Issue Handling +When creating a PR for an issue: +- [ ] Read the full issue and all linked references + - [ ] **new-feature:** State which version introduced the feature + - [ ] **bug:** Focus on correcting technical inaccuracies +- [ ] When you're assigned an issue, after you've completed your work and the workflows (status checks) have run, ensure there are no build warnings under the OpenPublishing.Build status check. If there are, open the build report (under View Details) and resolve any build warnings you introduced. +- [ ] When starting work on an issue, document your understanding in a comment: state the issue's purpose, expected outcome, and your implementation approach. + +### 2. Issue Discussion Analysis +When working on an issue: +- [ ] **Read the complete issue discussion** - Don't rely solely on the initial issue description +- [ ] **Prioritize maintainer guidance** - Comments from repository maintainers (especially those with "MEMBER" association) should take precedence over the original issue description +- [ ] **Look for updated analysis** - Later comments may contain revised understanding, additional context, or modified resolution approaches +- [ ] **Check for explicit instructions** - Look for phrases like "Action required by GitHub Copilot" or direct "@copilot" mentions that provide specific guidance +- [ ] **Validate your understanding** - If the discussion seems to contradict the initial issue description, follow the most recent maintainer guidance + +### 3. File Naming and Organization +**Naming conventions:** +- [ ] Name new Markdown files in all lowercase with hyphens separating words +- [ ] Omit filler words like "the" or "a" from file names + +**Folder structure:** +- [ ] Linux topics → `docs/linux/` +- [ ] C++ STL → `docs/standard-library/` +- [ ] C runtime → `docs/c-runtime-library/` +- [ ] C++ language → `docs/cpp/` +- [ ] Visual Studio IDE features → `docs/ide/` +- [ ] Build process/modules → `docs/build/reference/` +- [ ] Build Insights → `docs/build-insights/` + +### 4. Links and References +- [ ] Add links to related topics and resources where appropriate. +- [ ] Use relative links for files in this repo +- [ ] **[REQUIRED]** Links to other documentation articles should be relative, not absolute. Start relative links with `/docs/` and include the `.md` suffix. If you add a link to another page on learn.microsoft.com that's not in this repo, remove https://learn.microsoft.com/en-us from the link. +- [ ] **[REQUIRED]** Links to bookmarks within the same article should be relative and start with `#`. +- [ ] **[REQUIRED]** Link descriptions should be descriptive and make sense on their own. Don't use "click here" or "this link" or "here". +- [ ] **[STYLE]** When you are going to refer to another file or an article on the web, use this format: "For more information, see [descriptive name of link](link path)." The exception to this is the See Also links at the end of an article. Those should be markdown links and contain the title of the article you link to as the descriptive portion of the link. +- [ ] For external links to non-Microsoft sites: + - [ ] **[REQUIRED]** Use absolute URLs + - [ ] **[REQUIRED]** Remove any language or culture segment from the URL path (such as `/en-us/`, `/fr-fr/`, `/en/`, etc.) + - [ ] Example (MDN): + - [ ] Original: `https://developer.mozilla.org/en-US/docs/Web/API/Element/click_event` + - [ ] Correct: `https://developer.mozilla.org/docs/Web/API/Element/click_event` + +- [ ] For links to Microsoft Learn content in other repositories: + - [ ] **[REQUIRED]** Use the relative URL starting with a forward slash + - [ ] Don't include the scheme and the host (example: `https://learn.microsoft.com`) and don't include the locale (example: `en-us`) + - [ ] Example: For the target Learn website URL `https://learn.microsoft.com/en-us/dotnet/core/introduction`, use the relative URL `/dotnet/core/introduction` for the link destination + +## Repository-Specific Guidelines +- [ ] **[REQUIRED]** Follow the [Microsoft Writing Style Guide](https://learn.microsoft.com/en-us/style-guide/welcome/) + - [ ] Use contractions following the guidance in [Use contractions](https://learn.microsoft.com/en-us/style-guide/word-choice/use-contractions) +- [ ] **Repository Exceptions**: + - [ ] **[REQUIRED]** Use **bold** text for UI elements like menu items, dialog names, and names of text boxes. + - [ ] **[REQUIRED]** Number ordered lists as "1." for every item (don't use sequential numbers) + - [ ] **[REQUIRED]** Use backticks around content specifically for file names (`file.txt`), folders (`folder`), file paths (`folder/file.txt`), custom types (`myVariable`, `MyClass`), raw URLs in the text (`https://www.contoso.com`), file extensions (`.cpp`), and code like method names, property names, and language keywords. Also use for text that should never be localized. + - [ ] **[REQUIRED]** Use `code style` for resource names (like virtual machine names) that shouldn't be localized. + - [ ] **[C++-SPECIFIC]** Use `code style` for command-line commands. The style in some articles uses **bold** for command-line commands, but use `code style` instead. + - [ ] **[STYLE]** Use placeholders with braces in the format `{PLACEHOLDER NAME}` when used code examples and other contexts where placeholders are used.

Content Writing Guidelines +- [ ] **[STYLE]** Get to the point fast. Be concise and clear. +- [ ] **[STYLE]** Talk like a person. +- [ ] **[STYLE]** Simpler is better. +- [ ] **[STYLE]** Be brief. Give customers just enough information to make decisions confidently. Prune excess words. +- [ ] **[STYLE]** Break up long sentences. +- [ ] **[STYLE]** Use present tense verbs (is, open) instead of past tense (was, opened). For example, "The method returns a value" instead of "The method will return a value." +- [ ] **[STYLE]** Write factual statements and direct commands. Avoid hypotheticals. +- [ ] **[STYLE]** Use active voice where the subject performs the action. +- [ ] **[STYLE]** Write in second person (you) to speak directly to readers. +- [ ] **[STYLE]** Use gender-neutral language. +- [ ] **[STYLE]** Avoid multiple -ing words that could create ambiguity. +- [ ] **[STYLE]** Keep prepositional phrases simple and clear. +- [ ] **[STYLE]** Place modifiers close to what they modify. +- [ ] **[STYLE]** Use a conversational tone with contractions. +- [ ] **[STYLE]** Don't use "we" or "our" to refer to the authors of the documentation. +- [ ] **[STYLE]** Use the imperative mood for instructions. For example, "Call the method" instead of "You should call the method." +- [ ] **[STYLE]** Use "might" instead of "may" to indicate possibility. For example, "This method might throw an exception" instead of "This method may throw an exception." +- [ ] **[STYLE]** Use the Oxford comma in lists of three or more items. +- [ ] Introductory paragraph: + - [ ] When drafting the first paragraph of any new article, or when significantly updating an existing article: + - [ ] Explain why and when the topic matters in practical C++ development scenarios. + - [ ] Give a concise summary of what the article covers or enables, so readers know what to expect. + - [ ] When significantly updating, revise the introductory paragraph to match the new scope and content. + +### 6. PR Description Requirements +- [ ] ALWAYS include "Fixes #[issue-number]" in the PR description, at the first line of the description to link back to the original issue +- [ ] Include a clear summary of changes made +- [ ] List all files that were modified with brief descriptions + +## Capitalization + +- [ ] Use sentence-style capitalization for everything except proper nouns. +- [ ] Always capitalize proper nouns. +- [ ] Don’t capitalize the spelled-out form of an acronym unless it's a proper noun. +- [ ] Use title-style capitalization for product and service names. +- [ ] Don't use all uppercase for emphasis. + +## Numbers + +The following does NOT apply to step numbers but applies to all other numbers: +- [ ] Spell out numbers for zero through nine, unless space is limited. Use numerals for 10 and above. +- [ ] Spell out numbers at the beginning of a sentence. +- [ ] Spell out ordinal numbers such as first, second, and third. Don't add -ly to form adverbs from ordinal numbers. +- [ ] Number ordered list items all as 1. instead of sequentially as 1., 2., etc. Use bullets for unordered lists. + +## Punctuation + +- [ ] Use short, simple sentences. +- [ ] End all sentences with a period. +- [ ] Use one space after punctuation marks. +- [ ] After a colon, capitalize only proper nouns. +- [ ] Avoid semicolons - use separate sentences instead. +- [ ] Use question marks sparingly. +- [ ] Don't use slashes (/) - use "or" instead. + +## Headings + +- [ ] Headings should be in sentence case, not title case. Don't use gerunds in titles. +- [ ] Don't apply an inline style like italic, or bold to headings. But do use inline code style for headings that are code elements, like method names or property names. + +## Alerts + +- [ ] Alerts are a Markdown extension to create block quotes that render with colors and icons that indicate the significance of the content. The following alert types are supported: + + - [ ] `[!NOTE]` Information the user should notice even if skimming. + - [ ] `[!TIP]` Optional information to help a user be more successful. + - [ ] `[!IMPORTANT]` Essential information required for user success. + - [ ] `[!CAUTION]` Negative potential consequences of an action. + - [ ] `[!WARNING]` Dangerous certain consequences of an action. + +## Images + +- [ ] Use images only when they add value. +- [ ] Images have a descriptive and meaningful alt text that starts with "Screenshot showing" and ends with ".". +- [ ] Videos have a descriptive and meaningful alt text or title that starts with "Video showing" and ends with ".". + +## Numbered steps + +- [ ] Write complete sentences with capitalization and periods +- [ ] Use imperative verbs +- [ ] Clearly indicate where actions take place (UI location) +- [ ] For single steps, use a bullet instead of a number +- [ ] When allowed, use angle brackets for menu sequences (File > Open) + +## Terminology + +- [ ] Use "Select" instead of "Click" for UI elements like buttons, menu items, links, dropdowns, and checkboxes. \ No newline at end of file diff --git a/.github/copilot-issue-verification-action-plan.md b/.github/copilot-issue-verification-action-plan.md new file mode 100644 index 00000000000..3f6d7e270e6 --- /dev/null +++ b/.github/copilot-issue-verification-action-plan.md @@ -0,0 +1,220 @@ +--- +ai-usage: ai-assisted +author: TylerMSFT +ms.author: twhitney +ms.date: 11/13/2025 +--- + +# GitHub issue analysis and action plan prompt for C++ documentation + +## Goal +Analyze the GitHub issue and provide a **structured report** determining: +1.

Whenever two threads try to access the heap simultaneously, one thread is blocked until the other thread's request is finished. For many applications, this situation rarely occurs and the performance impact of the heap's locking mechanism is negligible.

This change prevents the template instantiation from happening in every file that includes `Templates.h`. Remove the current definition of `LargeValue()` from `Templates.h` and replace it with a declaration: + +```cpp +size_t LargeValue(); +``` + +Inside `LargeValue.cpp` add the definition: + +```cpp +size_t LargeValue() +{ + return sizeof(S3>); +} +``` + +Rebuild the project and run Build Insights again from the main menu. Select **Build** > **Run Build Insights on Selection** > **Rebuild**. + +The build time decreases. While the template instantiation of `S3` still contributes to the build time, including only necessary template instantiations cuts the build time nearly in half. The count of `S3` instantiations is now one instead of two. + +:::image type="complex" source="./media/templates-view-after-fix.png" alt-text="Screenshot of the Build Insights Templates view after optimization.

A program can safely rely on implementation-defined behavior, even though doing so might not be portable. Examples of implementation-defined behavior include the sizes of built-in data types and their alignment requirements. An example of an operation that might be affected by implementation-defined behavior is accessing the variable arguments list. -*Unspecified behavior* is behavior that the C++ standard leaves intentionally non-deterministic. Although the behavior is considered non-deterministic, particular invocations of unspecified behavior are determined by the compiler implementation. However, there is no requirement for a compiler vendor to predetermine the result or guarantee consistent behavior between comparable invocations, and there is no requirement for documentation. An example of unspecified behavior is the order in which sub-expressions, which include arguments to a function call, are evaluated. +*Unspecified behavior* is behavior that the C++ standard leaves intentionally nondeterministic.

For example, a 64-bit parameter is aligned on a 64-bit boundary. On x86 and x64, arguments that are passed on the stack are not subject to alignment and pack tightly. This difference can cause a variadic function like `printf` to read memory addresses that were intended as padding on ARM if the expected layout of the variable arguments list is not matched exactly, even though it might work for a subset of some values on the x86 or x64 architectures.

On the ARM architecture (except ARM64EC), the default is **/volatile:iso** because ARM processors have a weakly ordered memory model, and because ARM software doesn't have a legacy of relying on the extended semantics of **/volatile:ms** and doesn't usually have to interface with software that does. However, it's still sometimes convenient or even required to compile an ARM program to use the extended semantics. For example, it may be too costly to port a program to use the ISO C++ semantics, or driver software might have to adhere to the traditional semantics to function correctly. In these cases, you can use the **/volatile:ms** switch; however, to recreate the traditional volatile semantics on ARM targets, the compiler must insert memory barriers around each read or write of a **`volatile`** variable to enforce strong ordering, which can have a negative impact on performance. -On the x86, x64 and ARM64EC architectures, the default is **/volatile:ms** because much of the software that has already been created for these architectures by using MSVC relies on them.

If you place the decorated names produced by the Microsoft C++ (MSVC) compiler into a DEF file, applications that link to your DLL must also be built using the same version of MSVC so that the decorated names in the calling application match the exported names in the DLL's DEF file. > [!NOTE] > A DLL built with Visual Studio 2015 can be consumed by applications built with Visual Studio 2017 or Visual Studio 2019. diff --git a/docs/build/exporting-from-a-dll.md b/docs/build/exporting-from-a-dll.md index b05991ac322..d7513fc4776 100644 --- a/docs/build/exporting-from-a-dll.md +++ b/docs/build/exporting-from-a-dll.md @@ -4,6 +4,7 @@ title: "Exporting from a DLL" ms.date: "11/04/2016" helpviewer_keywords: ["exporting DLLs [C++], about exporting from DLLs", "exporting functions [C++], DLLs (exporting from)", "exporting DLLs [C++]", "DLLs [C++], exporting from", "DLL exports [C++]", "functions [C++], exporting", "exports table [C++]"] ms.assetid: a08f86c4-5996-460b-ae54-da2b764045f0 +ms.topic: concept-article --- # Exporting from a DLL diff --git a/docs/build/exporting-functions-from-a-dll-by-ordinal-rather-than-by-name.md b/docs/build/exporting-functions-from-a-dll-by-ordinal-rather-than-by-name.md index 1a3e10eeaeb..d5911954fb9 100644 --- a/docs/build/exporting-functions-from-a-dll-by-ordinal-rather-than-by-name.md +++ b/docs/build/exporting-functions-from-a-dll-by-ordinal-rather-than-by-name.md @@ -4,6 +4,7 @@ title: "Exporting Functions from a DLL by Ordinal Rather Than by Name" ms.date: "11/04/2016" helpviewer_keywords: ["exporting functions [C++], ordinal values", "ordinal exports [C++]", "exporting DLLs [C++], ordinal values", "NONAME attribute"] ms.assetid: 679719fd-d965-4df3-9f7a-7d86ad831702 +ms.topic: concept-article --- # Exporting Functions from a DLL by Ordinal Rather Than by Name diff --git a/docs/build/extension-dlls-overview.md b/docs/build/extension-dlls-overview.md index 9efaa880faa..b43f909510c 100644 --- a/docs/build/extension-dlls-overview.md +++ b/docs/build/extension-dlls-overview.md @@ -4,6 +4,7 @@ title: "Extension DLLs: Overview" ms.date: "05/06/2019" helpviewer_keywords: ["AFXDLL library", "MFC DLLs [C++], MFC extension DLLs", "DLLs [C++], extension", "shared DLL versions [C++]", "extension DLLs [C++], about MFC extension DLLs"] ms.assetid: eb5e10b7-d615-4bc7-908d-e3e99b7b1d5f +ms.topic: concept-article --- # MFC extension DLLs: Overview diff --git a/docs/build/fixing-release-build-problems.md b/docs/build/fixing-release-build-problems.md index b329363dc97..f10be40f3e4 100644 --- a/docs/build/fixing-release-build-problems.md +++ b/docs/build/fixing-release-build-problems.md @@ -4,6 +4,7 @@ title: "Fixing Release Build Problems" ms.date: "11/04/2016" helpviewer_keywords: ["release builds, troubleshooting", "debug builds, memory overwrites", "memory, overwrites", "troubleshooting Visual C++, release builds", "troubleshooting release builds"] ms.assetid: a0c0818e-4c47-4fe0-a611-50d61a41bd88 +ms.topic: concept-article --- # Fixing Release Build Problems diff --git a/docs/build/formatting-the-output-of-a-custom-build-step-or-build-event.md b/docs/build/formatting-the-output-of-a-custom-build-step-or-build-event.md index 938dc064259..b8c2ff6f181 100644 --- a/docs/build/formatting-the-output-of-a-custom-build-step-or-build-event.md +++ b/docs/build/formatting-the-output-of-a-custom-build-step-or-build-event.md @@ -4,6 +4,7 @@ title: "Formatting the output of a custom build step or build event" ms.date: 03/15/2022 helpviewer_keywords: ["builds [C++], build events", "custom build steps [C++], output format", "events [C++], build", "build events [C++], output format", "build steps [C++], output format", "builds [C++], custom build steps"] ms.assetid: 92ad3e38-24d7-4b89-90e6-5a16f5f998da +ms.topic: concept-article --- # Formatting the output of a custom build step or build event diff --git a/docs/build/get-started-linux-cmake.md b/docs/build/get-started-linux-cmake.md index 44cc20cf602..b2f59a73810 100644 --- a/docs/build/get-started-linux-cmake.md +++ b/docs/build/get-started-linux-cmake.md @@ -3,6 +3,7 @@ title: Create C++ cross-platform projects in Visual Studio description: "How to set up, compile, and debug a C++ open-source CMake project in Visual Studio that targets both Linux and Windows." ms.topic: tutorial ms.date: 02/07/2022 +ms.custom: sfi-image-nochange --- # Tutorial: Create C++ cross-platform projects in Visual Studio @@ -187,7 +188,7 @@ Because it's a desktop application, you need to provide some more configuration 1.

Scalar floating-point computations are usually performed with SSE or AVX instructions when available. Some calling conventions specify passing floating-point arguments on the x87 stack, and as a result, your code may use a mixture of both x87 and SSE/AVX instructions for floating-point computations.

Because SSE instructions were introduced with the subsequent Intel Pentium III processor, CMOVcc instructions may be generated except when **`/arch:IA32`** is specified. Floating-point operations are normally rounded to double-precision (64-bit) in x87 code, but you can use `_controlfp` to modify the FP control word, including setting the precision control to extended precision (80-bit) or single-precision (32-bit). For more information, see [`_control87`, `_controlfp`, `__control87_2`](../../c-runtime-library/reference/control87-controlfp-control87-2.md). SSE and AVX have separate single-precision and double-precision instructions for each operation, so there's no equivalent for SSE/AVX code.

For conversion to signed types, the sentinel is the minimum value for that type. Unsigned types use the maximum value. Floating-point operations may return a Not-a-Number (NaN) value to indicate an invalid operation. That indicator isn't an option for conversion to integer types, which don't have NaN values.

This gives you an opportunity to allocate or release additional resources as needed. Windows calls the entry-point function in four situations: process attach, process detach, thread attach, and thread detach. When a DLL is loaded into a process address space, either when an application that uses it is loaded, or when the application requests the DLL at runtime, the operating system creates a separate copy of the DLL data. This is called *process attach*. *Thread attach* occurs when the process the DLL is loaded in creates a new thread. *Thread detach* occurs when the thread terminates, and *process detach* is when the DLL is no longer required and is released by an application. The operating system makes a separate call to the DLL entry point for each of these events, passing a *reason* argument for each event type.

By using execution profile data collected from representative workloads, PGO enables the compiler to make smarter decisions about inlining, code layout, and hot/cold code separation. These decisions are impossible to make from static analysis alone. + +SPGO takes a different approach. Instead of instrumenting your binary and running it through synthetic training scenarios, SPGO uses hardware performance counter sampling collected from your actual release binaries. Modern processors provide hardware sampling capabilities. You can collect these samples with negligible runtime overhead, making it practical to gather runtime profiles directly from production code. + +Because SPGO profiles release bits instead of instrumented builds, it enables much more flexibility in where and how you collect data. You can gather runtime profiles from production servers, developer machines, performance labs, or any combination. The result is a binary that runs hot paths more efficiently, with a typical performance speedup of 5-15% depending on the quality of the profile data. + +For more information about Sample Profile‑Guided Optimization (PGO) in MSVC and how it improves performance using sampling‑based profiling, see [Introducing Sample Profile Guided Optimization in MSVC](https://devblogs.microsoft.com/cppblog/introducing-sample-profile-guided-optimization-in-msvc/) + +In this tutorial, you walk through the complete SPGO workflow: build a sample app, profile it by using `xperf`, prepare the profile data, and rebuild with the profile data.

The compiler uses that data to make better decisions about inlining, code layout, and branch prediction. A convenience is that no instrumentation is required. + +The workflow is: + +1. Build your binary with the [/spgo](./reference/spgo-enable-sample-profile-guided-optimization.md) linker flag. This step creates an empty **sample profile database** (`.spd` file). +1. Profile the binary by using `xperf` to produce an ETL trace file. +1. Convert the ETL to an **SPT** file by using [`SPTAggregate.exe`](sptaggregate.md), then convert the SPT to an **SPD** file by using [`SPDConvert.exe`](spdconvert.md). +1. Rebuild with the [/spdin](./reference/spdin-use-sample-profile-database.md) linker flag pointing to the populated sample profile database (SPD). The linker applies SPGO optimizations. + +The optimizer uses the SPD to answer questions like: which branches are taken most often? Which functions are called in hot loops? This process produces better code layout and inlining decisions than static analysis alone. + +SPGO works with both C and C++. The workflow and flags are identical for both languages. + +**Best candidates for SPGO:** Large, branch-filled C/C++ applications with tight inner loops. Gains scale with codebase size and branch complexity. The small sample in this tutorial shows around 7% improvement. Larger production codebases often see more improvement. + +## Build Process Comparison + +This section covers how SPGO fits into the build pipeline if you want to understand the mechanics. + +### Normal build process + +In a standard C/C++ release build: + +- **Inputs:** Source code files (`.cpp`, `.h`) and release-mode compiler flags (`/O2`, `/GL`, and so on). +- **Process:** The compiler applies standard optimizations such as inlining heuristics, branch prediction assumptions, and code layout decisions based on static analysis alone. It has no data about how the program actually behaves when it runs. +- **Output:** Executable (`.exe`), DLL files (`.dll`), debug information (`.pdb`). + +:::image type="content" source="media/normal-build-process.png" alt-text="Diagram of the normal release build process showing source code files and example compiler switch /GL as inputs flowing to a build step, which produces .exe, .dll, and .pdb outputs." lightbox="media/normal-build-process.png"::: + +Without runtime data, hot paths and cold paths receive similar treatment. + +### SPGO-enabled build process + +SPGO adds profiling data as a new input to the build pipeline: + +- **Inputs:** Source code, the `.spd` profile file (sample counts from a profiling run), release-mode compiler flags, `/link /spgo`, and `/spdin:` to specify an input SPD file (if not specified, defaults to a .spd using the binary name and located in the obj folder). +- **Process:** The linker reads the SPD alongside the intermediate code. It uses branch-frequency data to make better inlining, code layout, and branch-ordering decisions. Hot functions get laid out for fast access; cold code moves out of the critical path. +- **Output:** Optimized executable (`.exe`), optimized DLL files (`.dll`), debug information (`.pdb`), **and a new `.spd` file** for future profiling iterations. + +:::image type="content" source="media/sample-profile-guided-optimization-build-process.png" alt-text="Diagram of the SPGO-enabled build process showing source code and profile data files (.spd) as inputs to the build step with an additional linker switch /spgo.

The compiler gets exact execution counts but you have to instrument the code first. For more information about this process, see [Profile-guided optimizations](profile-guided-optimizations.md). + +SPGO uses hardware CPU performance counters to collect statistical samples from your uninstrumented release binary. Run your existing binary, profile it by using `xperf`, convert the trace to an SPD file, and rebuild. There's no instrumented build and no slowdown during profiling. The compiler gets statistical sampling data instead of exact counts, which is less precise but easier to get and requires no code changes. It also allows profiling of system components or realtime components that are difficult to collect data for with an instrumented approach. You can also profile final/shipping binaries. + +This tutorial covers three profiling methods: LBR, PMC, and OS timer. You choose your method in [Choose your profiling method](#choose-your-profiling-method). For a detailed comparison of the normal build process versus the SPGO build process, including a flag reference table, see [Build Process Comparison](#build-process-comparison). + +## Configure `perfcore.ini` + +> **⚠️ Required:** Without this step, `xperf` doesn't provide the necessary profiling data. Complete this step before running `xperf`. + +The Windows Performance Toolkit (WPT) uses `perfcore.ini`, located if you installed the WPT in the default location at `C:\Program Files (x86)\Windows Kits\10\Windows Performance Toolkit\perfcore.ini`, to register the DLL providers it needs for SPGO. + +Open Windows Notepad as Administrator. Then open `perfcore.ini`. Find the DLL list section and add the following entries, one per line: + +``` +perf_lbr.dll +perf_spt.dll +perf_hv.dll +``` + +If `xperf.exe` isn't installed, see [General issues](#general-issues-all-paths) to install it. + +Save and close `perfcore.ini`. The DLL files already ship in the same directory as `xperf.exe` so you don't need to copy them anywhere. You're only registering them in `perfcore.ini`. Ensure that `xperf` is in your path. + +## Create the sample app + +The sample app for this tutorial is a C++ program that reads text from standard input and produces a line count, word count, total character count, a character frequency table, and elapsed time to process the file in milliseconds.

A higher percentage is better. Coverage above 70% is excellent, while coverage below 40% might limit optimization effectiveness. If coverage is low, run the profiling workload longer or combine multiple SPT files from separate runs with different workloads. For example, you could run `textCount` against multiple text files to exercise different code paths. + +You might see a warning from `SPDConvert` like the following: + +``` +Compiler may be conservative on some hot functions due to sparse sample coverage. +SPGO is estimated to optimize better if sample density is increased to 5.4x of current level. +Sample density can be increased by sampling for longer period, or increasing sample rate. +``` + +This warning means your profiling run didn't collect enough samples for the optimizer to confidently optimize all hot functions. The SPD is still usable, but you can improve results by: + +- Running the workload longer (for example, 5 or more minutes instead of 1 minute) or using different workloads. +- Lowering the `-setProfInt` value in the `xperf` command to increase the sampling rate. The tradeoff is that this change produces a larger ETL file, which takes longer to process. +- Combining multiple SPT files from separate profiling runs by passing them all to `SPDConvert`. + +The SPT file is a binary format. To inspect its contents, you can run `SPTDump.exe textCount.spt`. Similarly, `PTDump.exe textCount.spt` shows the compiled profile data after running `SPDConvert`. Both tools are useful for verifying nonzero samples before proceeding. + +## Rebuild textCount with /spdin + +Rebuild `textCount` by using the populated SPD file. The linker reads the profile data and applies SPGO optimizations. + +This step is the same for all three profiling paths. + +```cmd +cl /Zi /EHsc /GL /O2 textCount.cpp /link /debug /spgo /spdin:textCount.spd +``` + +**New flag (compared to [Build textCount with /spgo](#build-textcount-with-spgo)):** + +| Flag | Purpose | +|------|---------| +| `/spdin:textCount.spd` | Provide the SPD profile data to the linker for optimization | + +The command still includes `/spgo`. It generates a new SPD file alongside the optimized binary, which you can use as the starting point for subsequent profiling iterations. + +> [!WARNING] +> The SPD file is associated with the exact binary it profiles against. If you rebuild `textCount` without `/spdin`, or rebuild from changed source, you must generate a new SPD file. The existing one doesn't match the new binary's GUID, and the linker won't use it. + +After the rebuild with `/spdin`, the linker outputs statistics about how much of your code was optimized using profile data. For example: + +``` +221 of 221 (100.00%) profiled functions will be compiled for speed +201 of 1383 inline instances were from dead/cold paths +474 of 474 profiled functions (100.0%) were optimized using profile data +202738780 of 202738780 instructions (100.0%) were optimized using profile data +``` + +A high percentage means the SPD covers your binary well. If the percentage is low (for example, below 90%), either the profiling workload didn't exercise enough of the binary, or the binary has changed significantly since the profile was collected. In both cases, reprofile against the current binary. + +### What SPGO does with your profile data + +SPGO uses the collected sample data to populate counts on each block and edge in the program's control flow graph. These counts drive optimizations such as: +- **Profile-guided inlining**: Aggressively inline hot call sites while avoiding code bloat from inlining cold paths. +- **Hot/cold code separation**: Move rarely executed code to separate sections of the binary, improving instruction cache utilization and paging behavior. +- **Function layout**: Place functions that call each other frequently near each other in the binary, reducing page faults and improving locality. Optimized functions are organized into high affinity COFF groups in the binary. +- **Size/speed decisions**: Compile hot functions for speed and cold functions for size. Routines with no observed profile hits might be compiled for size rather than speed, limiting optimizations like inlining and loop unrolling in those cold paths. +- **Speculative devirtualization**: When sampling reveals that an indirect call consistently targets the same function, SPGO can speculate on that target and inline it, with a fallback for the uncommon case. + +## Measure the results + +Run `textCount` again and compare elapsed times. + +```cmd +textCount.exe < warAndPeace.txt +``` + +Collect multiple runs for each configuration and use the median. A single run isn't reliable because OS scheduling and system noise can skew individual measurements. + +| Build | Representative elapsed time | +|-------|-----------------------------| +| Baseline (`cl /Zi /EHsc /O2 /link /debug`) | *(your measurement)* | +| `/spgo` build (no profile data yet) | *(should be close to baseline)* | +| SPGO-optimized (`/spdin`) | *(should show improvement)* | + +In one test, SPGO using the LBR method delivered approximately 7% reduction in elapsed time. Your results might vary with your own projects because SPGO gains depend on how well the profiling workload represents typical execution. Larger, branch filled codebases tend to see more improvement within the 5–10% range. The profiling method affects optimization quality. LBR typically produces better results than PMC, which produces better results than OS timer. If you're on the OS timer path, expect smaller gains. + +The LBR path followed in this tutorial was applied to the [SQLite](https://github.com/sqlite/sqlite) project, which is a production database library. The SPGO-optimized SQLite binary showed approximately a 7% improvement. + +## Apply SPGO to your own project + +Use this checklist to apply SPGO to your own C or C++ application. + +1. **Add `/Zi /link /debug /spgo` to your existing release build command.** Modify your build script or project file: + + ```cmd + cl /Zi /EHsc /GL /O2 myapp.cpp /link /debug /spgo + ``` + +1. **Choose a representative workload.** Select a real usage scenario that exercises the hot paths of your application. Use production-like data. Avoid the following as your primary profiling workload: code coverage tests (they don't stress performance bottlenecks), uncommon error paths, startup and shutdown phases, and deprecated code paths. This workload drives the profile that feeds the optimizer. +1. **Run xperf using your detected path.** Use the path you identified in [Choose your profiling method](#choose-your-profiling-method) (LBR, PMC, or OS timer). Start `xperf`, run the workload once, stop `xperf`, and capture the ETL file. +1. For the PMC or OS timer path, **run SPTAggregate and SPDConvert with the correct `/mode` flag.** Convert ETL to SPT then to SPD. Use `/mode:LBR` for LBR data; use `/mode:IP` for PMC or OS timer data. +1. **Rebuild with `/spdin:`.** Compile your application with the populated SPD: + + ```cmd + cl /Zi /EHsc /GL /O2 yourApp.cpp /link /debug /spgo /spdin:yourApp.spd + ``` + +1. **Measure before and after.** Run your workload with both the nonoptimized and SPGO-optimized binaries. Collect the **median of multiple runs** for each configuration. A single run isn't reliable for benchmarking. +1. **Store the `.spd` file in source control.** Check the `.spd` file into your source control system alongside your source code. +1. **Enable SPGO in developer Release builds.** Have your team's Release builds use the same SPGO-optimized binaries as production. This helps catch performance regressions early. +1. Disable SPGO in Debug builds. +1. **Watch the linker's profile completeness statistics.** After each build with `/spgo`, note the percentage of profiled functions optimized using profile data. If this drops significantly (below 90%), reprofile the current binary. Code changes accumulate and the SPD can become stale. + +### Alternative to using `xperf` + +Another way to gather profile data is to use a sampling profiler like Windows Performance Recorder (WPR). WPR is installed by default on Windows 10 and later. It collects similar data to `xperf`. You can configure WPR to collect CPU samples with call stacks, and then export the data to an ETL file that you can process with `SPTAggregate` and `SPDConvert` like the `xperf` ETL. Here's an example of using WPR to collect profile data: + +```cmd +wpr -start CPU.light -filemode +textCount.exe < warAndPeace.txt +wpr -stop spgo_data.etl +``` +For more information on using WPR, see [Using Windows Performance Recorder](/windows-hardware/test/wpt/recording-pmu-events). + +### SPD distribution + +You can: + +- Check the `.spd` file directly into source control alongside your source code. +- Share the `.spd` file with teammates so they can build with SPGO optimizations without reprofiling. +- Package the `.spd` file with your binaries as a versioned artifact (for example, a NuGet package) and record which version corresponds to which binary. +- Regenerate the `.spd` file at any time by repeating the profiling workflow. + +The SPD ties to the exact binary it was built from. After significant code changes, reprofile to generate a fresh SPD. During the `/spdin` build, the compiler also produces a new `.spd` file. Save this new SPD as a build artifact - it's the starting point for your next profiling iteration. + +## Reusing SPD information across builds + +The "carry forward" concept in SPGO allows you to add profiling data to an existing SPD file without profiling all your scenarios over again from scratch and without losing existing profile information. You can also adjust how much weight to give to older profile data. This flexibility is useful when there might be behavioral changes over time and you don't want to completely lose the profiling information from earlier scenario runs. For instance, a DLL might see different APIs called as the application that calls it evolves. You still want the optimizations from how it used to behave, but want to mix in optimization opportunities for how it sometimes behaves differently now. You can evolve the profile over time by mixing old and new data. + +When you run `SPDConvert` with a new SPT file, pass the name of the existing SPD file. Then use the `/retire:N` option to control how aggressively `SPDConvert` de-emphasizes older profile data when you add new SPT files: +- The default (`/retire:8`) weights newer data more heavily. +- Use `/retire:0` to give equal weight to all runs. +- Use `/retire:16` to let only the newest data count. + +## Troubleshooting + +> **Find your issue:** +> - **LBR path problems:** [LBR path problems](#lbr-path-problems) +> - **PMC path problems:** [PMC path problems](#pmc-path-problems) +> - **OS timer problems:** [OS timer path problems](#os-timer-path-problems) +> - **Issues affecting all paths:** [General issues](#general-issues-all-paths) + +### LBR path problems + +| Problem | Likely cause | Fix | +|---------|-------------|-----| +| Zero LBR samples in `SPTAggregate` output | CPU doesn't support LBR, or VM doesn't expose LBR | Run the detection command from [Detect your path](#detect-your-path).

A blended SPD reflects the full range of real usage patterns and produces better optimizations than a single-scenario profile. Use the `/retire:N` option to control how aggressively `SPDConvert` de-emphasizes older profile data when you add new SPT files. The default (`/retire:8`) weights newer data more heavily. Use `/retire:0` to give equal weight to all runs; use `/retire:16` to let only the newest data count. +- The best results come from blending profiles from multiple sources such as benchmarks that stress key scenarios plus real-world data (where available). Pass SPT files from all sources to `SPDConvert`. Repeat an SPT file in the argument list to give it more weight (for example, `SPDConvert myapp.spd critical.spt critical.spt common.spt` weights `critical.spt` twice as heavily as `common.spt`). +- **Iterative optimization:** Each rebuild with `/spdin` produces a new SPD. You can repeat the run, profile, rebuild cycle. Later iterations might show diminishing returns, but a second pass can sometimes capture patterns the first missed. +- **Code changes:** After significant source changes, recollect profile data. The existing SPD is tied to the binary it was profiled against. It won't match a substantially rebuilt binary. +- **Profile freshness:** The linker reports the percentage of profiled functions optimized using profile data after each `/spdin` build. If this percentage drops significantly, it's a signal that the code has diverged from the profile.

A *fundamental alignment* is an alignment that's less than or equal to the largest alignment that's supported by the implementation without an alignment specification.

For example, a four-byte allocation would be aligned on a boundary that supports any four-byte or smaller object. Visual C++ permits types that have *extended alignment*, which are also known as *over-aligned* types. For example, the SSE types [__m128](../cpp/m128.md) and `__m256`, and types that are declared by using `__declspec(align( n ))` where `n` is greater than 8, have extended alignment. Memory alignment on a boundary that's suitable for an object that requires extended alignment is not guaranteed by `malloc`.

First, the author of the assembly can manually create a manifest file by following the rules and naming requirements. For more information, see [Manifest files reference](/windows/win32/sbscs/manifest-files-reference). Alternatively, if a program only depends on Microsoft C++ (MSVC) assemblies such as CRT, MFC, ATL or others, then the linker can generate a manifest automatically. The headers of MSVC libraries contain assembly information, and when the libraries are included in application code, this assembly information is used by the linker to form a manifest for the final binary. By default, the linker doesn't embed the manifest file inside the binary. Having a manifest as an external file may not work for all scenarios. For example, it's recommended that private assemblies have embedded manifests. In command line builds such as ones that use NMAKE to build code, you can use the [`/MANIFEST:EMBED`](./reference/manifest-create-side-by-side-assembly-manifest.md) linker option to embed the manifest. Alternatively, a manifest can be embedded using the manifest tool. For more information, see [Manifest generation at the command line](#manifest-generation-at-the-command-line).

A client app _imports_ the names to use those variables, functions, and resources. Unlike a statically linked library, Windows connects the imports in your app to the exports in a DLL at load time or at run time, instead of connecting them at link time. Windows requires extra information that isn't part of the standard C++ compilation model to make these connections. The MSVC compiler implements some Microsoft-specific extensions to C++ to provide this extra information. We explain these extensions as we go. -This walkthrough creates two Visual Studio solutions; one that builds the DLL, and one that builds the client app. The DLL uses the C calling convention. It can be called from apps written in other programming languages, as long as the platform, calling conventions, and linking conventions match.

This linking lets the app call the DLL-supplied functions just like the functions in a statically linked library. +This walkthrough creates two Visual Studio solutions: one that builds the DLL, and one that builds the client app. The DLL uses the C calling convention.

The volatile portion consists of the six status flags, in `MXCSR\[0:5]`, while the rest of the register, `MXCSR\[6:15]`, is considered nonvolatile. The nonvolatile portion is set to the following standard values at the start of program execution: | Register\[bits] | Setting | |-|-| -| MXCSR\[6] | Denormals are zeros - 0 | -| MXCSR\[7:12] | Exception masks all 1's (all exceptions masked) | -| MXCSR\[13:14] | Rounding control - 0 (round to nearest) | -| MXCSR\[15] | Flush to zero for masked underflow - 0 (off) | +| `MXCSR\[6]` | Denormals are zeros - 0 | +| `MXCSR\[7:12]` | Exception masks all 1s (all exceptions masked) | +| `MXCSR\[13:14]` | Rounding control - 0 (round to nearest) | +| `MXCSR\[15]` | Flush to zero for masked underflow - 0 (off) | -A callee that modifies any of the nonvolatile fields within MXCSR must restore them before returning to its caller.

Exception-safe code which modifies the nonvolatile portions of `MXCSR` should resort to an exception finalizer (e.g. C++ destructor or a `__finally` clause) to restore it explicitly, when unwinding the stack. ## setjmp/longjmp -When you include setjmpex.h or setjmp.h, all calls to [`setjmp`](../c-runtime-library/reference/setjmp.md) or [`longjmp`](../c-runtime-library/reference/longjmp.md) result in an unwind that invokes destructors and **`__finally`** calls. This behavior differs from x86, where including setjmp.h results in **`__finally`** clauses and destructors not being invoked. +When you include `setjmpex.h` or `setjmp.h`, all calls to [`setjmp`](../c-runtime-library/reference/setjmp.md) or [`longjmp`](../c-runtime-library/reference/longjmp.md) result in an unwind that invokes destructors and `__finally` calls. This behavior differs from x86, where including `setjmp.h` results in `__finally` clauses and destructors not being invoked. + +A call to `setjmp` preserves the current stack pointer, nonvolatile registers, and `MXCSR` registers. Calls to `longjmp` return to the most recent `setjmp` call site and resets the stack pointer, nonvolatile registers, and `MXCSR` registers, back to the state as preserved by the most recent `setjmp` call. + +If APX is supported, `R30` and `R31` should not be modified in a function from the point `setjmp` is called to the point where the call which ultimately results in `longjmp` is made. This limitation is the result of `R30` and `R31` not being saved as part of `jmp_buf` - this structure definition cannot change. Instead, they are restored via the unwinder. The following example demonstrates how the difference on how the data is restored influences this restriction: + +```c +jmp_buf jmpbuffer; + +void function_a() { + ... + + int val = setjmp(jmpbuffer); // At this time R30 is 10 + + ... + + if (val == 0) { + function_b(); // At this time R30 is 20 + } + + ... +} + +void function_b() { + ... + + longjmp(jmpbuffer, 1); + + ... +} +``` + +In this example, the value of `R30` changes from the point where `setjmp` is called to the point `function_b` is called. In `function_b`, `longjmp` unwinds the stack until it reaches the function which called `setjmp` (`function_a` in this case). The value restored for `R30` will be `20` (the value at the point `function_b` was called), not `10` (the value at which `setjmp` was called). This means that when `setjmp` returns for the second time (as the result of `longjmp`) the value of `R30` will be set to `20` instead of `10`, which is incorrect. This is why compilers must ensure `R30` and `R31` remain constant from the point `setjmp` is called to the last place in the function which could ultimately result in `longjmp` being called. -A call to `setjmp` preserves the current stack pointer, non-volatile registers, and MXCSR registers. Calls to `longjmp` return to the most recent `setjmp` call site and resets the stack pointer, non-volatile registers, and MXCSR registers, back to the state as preserved by the most recent `setjmp` call. +Since `longjmp` can be called from an exception filter (not just a sub-routine), this effectively dictates that `R30` and `R31` should remain constant from the point `setjmp` is called through the rest of the function. ## See also -[x64 software conventions](../build/x64-software-conventions.md) +- [Overview of x64 ABI conventions](../build/x64-software-conventions.md) diff --git a/docs/build/x64-software-conventions.md b/docs/build/x64-software-conventions.md index 256fbdb581e..fdb9f859bd9 100644 --- a/docs/build/x64-software-conventions.md +++ b/docs/build/x64-software-conventions.md @@ -1,8 +1,9 @@ --- description: "Learn more about: x64 ABI conventions" title: "x64 ABI conventions" -ms.date: 04/21/2022 +ms.date: 03/28/2025 helpviewer_keywords: ["x64 coding conventions", "x64 abi", "Visual C++, x64 calling conventions"] +ms.topic: concept-article --- # Overview of x64 ABI conventions @@ -11,10 +12,11 @@ This topic describes the basic application binary interface (ABI) for x64, the 6 ## x64 calling conventions Two important differences between x86 and x64 are: + - 64-bit addressing capability - Sixteen 64-bit registers for general use. -Given the expanded register set, x64 uses the [__fastcall](../cpp/fastcall.md) calling convention and a RISC-based exception-handling model. +Given the expanded register set, x64 uses the [`__fastcall`](../cpp/fastcall.md) calling convention and a RISC-based exception-handling model.

Bit 1: `EPILOG_INFO_LARGE` - when set, the extended descriptor uses `EPILOG_INFO_LARGE_EX_V3` (16-bit `IpOffsetOfLastInstruction`) and each IP offset entry is 16-bit, accommodating epilogs exceeding 255 bytes. Bit 2: reserved (zero). | +| `NumberOfOps` | Number of WODs for this epilog (0–31). Zero is a special value meaning "inherit from previous epilog descriptor." | +| `EpilogOffset` | 16-bit signed displacement to the first instruction of this epilog. For the first epilog descriptor: positive values are byte offsets from the fragment start, and negative values are byte offsets from the fragment tail, that is, the first byte past the end. For subsequent epilog descriptors: delta from the start of the previous epilog. All epilogs must use the same sign - either all sorted ascending from start, or all sorted descending from tail. | +| `FirstOp` | Byte index into the WOD pool where the first WOD for this epilog resides. This is a byte offset, not a WOD index. Epilogs may share WODs with the prolog or with each other by pointing into the same pool region. | +| `IpOffsetOfLastInstruction` | Unsigned byte offset from the epilog start of the last instruction in the epilog, typically RET, or JMP. 8-bit in `EPILOG_INFO_EX_V3`; 16-bit in `EPILOG_INFO_LARGE_EX_V3`. The unwinder uses this value to determine where the epilog ends and the function body resumes. | + +#### Epilog IP Offsets + +Immediately after each full epilog descriptor (when `NumberOfOps > 0`), an array of `NumberOfOps` entries gives the IP offset of each epilog instruction that has a corresponding WOD. Each entry is an unsigned byte, or an unsigned 16-bit word when `EPILOG_INFO_LARGE` is set. Ordering: first entry = operation closest to the body (first epilog instruction with an unwind effect), last entry = operation closest to the control-transfer instruction. + +### WOD Pool + +The remaining bytes in the payload form the WOD pool. The prolog's WODs implicitly start at byte offset 0 of this pool. Each epilog's WOD list start at the byte offset given by its `FirstOp` field. WODs are packed with no alignment or padding between them. + +The number of WODs consumed for the prolog is `UNWIND_INFO_V3.NumberOfOps`.

The default behavior is to print the message. `_CALL_REPORTFAULT`, if set, invokes the Windows Error Reporting Service mechanism (formerly known as Dr. Watson) to report failures to Microsoft when `abort` is called. By default, crash dump reporting is enabled in non-DEBUG builds.

A function may introduce a locking side effect by making an observable modification to the concurrency state. For example, a lock wrapper function increments the number of lock acquisitions, or lock count, for a given lock. You can annotate a function that has a side effect from a lock acquire or lock release by using `_Acquires_lock_` or `_Releases_lock_`, respectively. Without such annotations, a function is expected not to change any lock count after it returns. If acquires and releases aren't balanced, they're considered to be *orphaned*. Warning C26117 is issued when a function that hasn't been annotated with `_Releases_lock_` releases a lock that it doesn't hold, because the function must own the lock before it releases it. ## Examples diff --git a/docs/code-quality/c26130.md b/docs/code-quality/c26130.md index fb1912520c6..990d87c2b3e 100644 --- a/docs/code-quality/c26130.md +++ b/docs/code-quality/c26130.md @@ -1,15 +1,16 @@ --- +title: "Warning C26130" description: "Learn more about: Warning C26130" -title: Warning C26130 ms.date: 11/04/2016 f1_keywords: ["C26130"] helpviewer_keywords: ["C26130"] -ms.assetid: 535e2356-bc84-4549-983d-7d29aee2249c --- # Warning C26130 > Missing annotation \_Requires\_lock\_held\_('*lock*') or \_No\_competing\_thread\_ at function '*func*'.

If the type hierarchy is designed to disallow client code to destroy objects directly, destructors should be defined as protected non-virtual. diff --git a/docs/code-quality/c26437.md b/docs/code-quality/c26437.md index 5757f17f667..1ec3dbc4327 100644 --- a/docs/code-quality/c26437.md +++ b/docs/code-quality/c26437.md @@ -4,7 +4,6 @@ description: "Learn more about: Warning C26437 DONT_SLICE" ms.date: 05/17/2023 f1_keywords: ["C26437", "DONT_SLICE"] helpviewer_keywords: ["C26437"] -ms.assetid: ed2f55bc-a6d8-4cc4-8069-5c96e581a96a --- # Warning C26437 diff --git a/docs/code-quality/c26438.md b/docs/code-quality/c26438.md index e6c696ca31d..dd7f16b4ebf 100644 --- a/docs/code-quality/c26438.md +++ b/docs/code-quality/c26438.md @@ -11,7 +11,7 @@ ms.assetid: c7b3f59c-fb2f-4816-bda4-0fad23c80d83 > Avoid `goto` (es.76) **C++ Core Guidelines**:\ -[ES.76](https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#es76-avoid-goto): Avoid goto +[ES.76](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Res-goto): Avoid goto The use of **`goto`** is widely considered a dangerous and error-prone practice.

You can typically resolve these cases in one of two ways: Either change `_Out_` to a more appropriate annotation, or use the `_Success_()` annotation to help define the success/error states of the function. It's important for the static analysis tools to have correct annotations on the function when analyzing the call sites of the function. diff --git a/docs/code-quality/c6102.md b/docs/code-quality/c6102.md index d1dd840a693..e003c84636b 100644 --- a/docs/code-quality/c6102.md +++ b/docs/code-quality/c6102.md @@ -1,14 +1,16 @@ --- +title: "Warning C6102" description: "Learn more about: Warning C6102" -title: Warning C6102 ms.date: 11/04/2016 f1_keywords: ["C6102"] -ms.assetid: cfd49a8c-df46-48de-8dcb-02ecf2450034 +helpviewer_keywords: ["C6102"] --- # Warning C6102 > Using '*variable*' from failed function call at line '*location*'. +## Remarks + This warning is reported instead of [C6001](../code-quality/c6001.md) when a variable isn't set because it was marked as an `_Out_` parameter on a prior function call that failed.

A *module* is a set of source code files that are compiled independently of the source files (or more precisely, the [translation units](https://wikipedia.org/wiki/Translation_unit_(programming))) that import them. Modules eliminate or reduce many of the problems associated with the use of header files. They often reduce compilation times, sometimes significantly. Macros, preprocessor directives, and nonexported names declared in a module aren't visible outside the module. They have no effect on the compilation of the translation unit that imports the module. You can import modules in any order without concern for macro redefinitions. Declarations in the importing translation unit don't participate in overload resolution or name lookup in the imported module. After a module is compiled once, the results are stored in a binary file that describes all the exported types, functions, and templates. The compiler can process that file much faster than a header file.

If a hidden parameter is required for struct returns, it's passed in `r13` (the first parameter register), reducing available parameter registers to 9. Registers `r10`-`r12` are reserved for various CRT and Windows runtimes. All parameters must be passed through registers; stack-based parameters aren't currently supported. | +| Register allocation strategy | To help minimize register spilling when calling functions with different calling conventions, the allocator assigns `rcx`, `rdx`, `r8`, and `r9` only after other registers have been used, since those registers are used first by the [__vectorcall](vectorcall.md) and [__cdecl](cdecl.md) calling conventions. | +| Argument limit | Functions are restricted to a maximum of 10 parameters. An error is generated if this limit is exceeded. | +| Return value convention | Follows the regular x64 calling convention rules. Scalar return values are returned in `rax`. Structs of size 1, 2, 4, or 8 bytes are returned through the `rax` register. For structs of other sizes, a pointer to memory allocated by the caller and passed through the hidden parameter is returned in `rax`. | +| Volatile registers | All general-purpose registers except `r12`, `rsp` (stack pointer) and `rbp` (base pointer) are treated as volatile and don't need to be preserved across function calls. While `r10` and `r11` are volatile, they aren't used for parameter passing to maintain compatibility with existing programs. | +| Nonvolatile registers | Only `rsp`, `rbp`, and `r12` are nonvolatile. | +| Stack alignment | The stack must maintain 16-byte alignment. | +| Frame pointer | The `rbp` register and frame chain follow the [/Gy switch](../build/reference/gy-enable-function-level-linking.md) settings. | +| Stack-maintenance responsibility | The callee is responsible for cleaning up its own stack space. | +| Shadow space | 32 bytes are reserved on the stack as a shadow space to maintain compatibility with profilers and debugging tools. *(Shadow space is a reserved area on the stack where register parameters can be spilled if needed.

Before standard library modules, you'd include the part of the standard library you needed with a directive like `#include `. Header files are fragile and difficult to compose because their semantics may change depending on the order you include them, or whether certain macros are defined. They also slow compilation because they're reprocessed by every source file that includes them. C++20 introduces a modern alternative called *modules*. In C++23, we were able to capitalize on module support to introduce named modules to represent the standard library. Like header files, modules allow you to share declarations and definitions across source files. But unlike header files, modules aren't fragile and are easier to compose because their semantics don't change due to macro definitions or the order in which you import them.

In some cases—for example, if you are not making a large number of lookups or insertions, and you are passing the collection across the ABI frequently—it might be less expensive to use `Platform::Collections::Map` from the beginning and avoid the cost of converting the `std::map`. In any case, avoid lookup and insert operations on an `IMap` because these are the least performant of the three types. Convert to `IMap` only at the point that you pass the container across the ABI. ## Value types in Map -Elements in a [Platform::Collections::Map](../cppcx/platform-collections-map-class.md) are ordered. Any element to be stored in a `Map` must support less-than comparison with strict weak ordering, either implicitly or by using a custom [stl::less](../standard-library/less-struct.md) comparator that you provide. Scalar types support the comparison implicitly. For non-scalar value types such as `Windows::Foundation::DateTime`, or for custom comparisons—for example, `objA->UniqueID < objB->UniqueID`—you must provide a custom comparator. +Elements in a [`Platform::Collections::Map`](platform-collections-map-class.md) are ordered.

In addition, C++/CX enhances collections by providing three iterator classes that simplify the accessing of collections. -Elements of a modifiable collection can be changed, but elements of a read-only collection, which is known as a *view*, can only be read. Elements of a [Platform::Collections::Vector](../cppcx/platform-collections-vector-class.md) or[Platform::Collections::VectorView](../cppcx/platform-collections-vectorview-class.md) collection can be accessed by using an iterator or the collection's [Vector::GetAt](../cppcx/platform-collections-vector-class.md#getat) and an index. Elements of an associative collection can be accessed by using the collection's [Map::Lookup](../cppcx/platform-collections-map-class.md#lookup) and a key. +Elements of a modifiable collection can be changed, but elements of a read-only collection, which is known as a *view*, can only be read.

Code reuse can save both time and effort when creating apps for multiple platforms. diff --git a/docs/data/catalog-information-mfc-data-access.md b/docs/data/catalog-information-mfc-data-access.md index 6935e8ae313..39e786d3e45 100644 --- a/docs/data/catalog-information-mfc-data-access.md +++ b/docs/data/catalog-information-mfc-data-access.md @@ -1,11 +1,10 @@ --- -description: "Learn more about: Catalog Information (MFC Data Access)" -title: "Catalog Information (MFC Data Access)" -ms.date: "11/04/2016" +title: "Catalog Information (MFC Data Access)" +description: "Learn more about: Catalog Information (MFC Data Access)" +ms.date: 11/04/2016 helpviewer_keywords: ["tables [C++], catalog information", "tables [C++]", "ODBC [C++], catalog information", "catalog information database [C++]", "databases [C++], catalog information database"] -ms.assetid: c184e80f-ff17-409f-9df8-05275080bb8d --- -# Catalog Information (MFC Data Access) +# Catalog Information (MFC Data Access) Information about the tables in a data source can include the names of tables and the columns in them, table privileges, names of primary and foreign keys, information about predefined queries or stored procedures, information about indexes on tables, and statistics about tables. diff --git a/docs/data/changes-you-might-make-to-the-default-code-mfc-data-access.md b/docs/data/changes-you-might-make-to-the-default-code-mfc-data-access.md index d524c7ae40c..36779b2c17c 100644 --- a/docs/data/changes-you-might-make-to-the-default-code-mfc-data-access.md +++ b/docs/data/changes-you-might-make-to-the-default-code-mfc-data-access.md @@ -1,10 +1,10 @@ --- -title: "Changes You Might Make to the Default Code (MFC Data Access)" -description: "Learn more about: Changes You Might Make to the Default Code (MFC Data Access)" -ms.date: "11/04/2016" +title: "Changes You Might Make to the Default Code (MFC Data Access)" +description: "Learn more about: Changes You Might Make to the Default Code (MFC Data Access)" +ms.date: 11/04/2016 helpviewer_keywords: ["record views [C++], customizing default code"] --- -# Changes You Might Make to the Default Code (MFC Data Access) +# Changes You Might Make to the Default Code (MFC Data Access) The [MFC Application Wizard](../mfc/reference/database-support-mfc-application-wizard.md) writes a recordset class for you that selects all records in a single table.

However, we're no longer adding features or updating the documentation. + Over the years, Visual C++ has provided several ways to work with databases. In 2011 Microsoft announced that it is aligning on Open Database Connectivity (ODBC) as the preferred technology for accessing SQL Server products from native code. ODBC is an industry standard, and by using it you gain maximum portability of your code over multiple platforms and data sources. Most SQL database products and many NoSQL products support ODBC. You can use ODBC directly by calling the low-level ODBC APIs, or you can use the MFC ODBC wrapper classes, or a third-party C++ wrapper library. OLE DB is a low-level, high-performance API based on the COM specification, and is only supported on Windows. Use OLE DB if your program is accessing [linked servers](/sql/relational-databases/linked-servers/linked-servers-database-engine). ATL provides OLE DB templates that make it easier to create custom OLE DB providers and consumers. The most recent provider for Microsoft SQL Server can be found in the documentation for the [OLE DB Driver for SQL Server](/sql/connect/oledb/oledb-driver-for-sql-server). diff --git a/docs/data/data-exchange-for-record-views-mfc-data-access.md b/docs/data/data-exchange-for-record-views-mfc-data-access.md index 08307d190cf..cf7e9e780d0 100644 --- a/docs/data/data-exchange-for-record-views-mfc-data-access.md +++ b/docs/data/data-exchange-for-record-views-mfc-data-access.md @@ -1,11 +1,10 @@ --- -description: "Learn more about: Data Exchange for Record Views (MFC Data Access)" -title: "Data Exchange for Record Views (MFC Data Access)" -ms.date: "11/19/2018" +title: "Data Exchange for Record Views (MFC Data Access)" +description: "Learn more about: Data Exchange for Record Views (MFC Data Access)" +ms.date: 11/19/2018 helpviewer_keywords: ["RFX (record field exchange), data exchange mechanism", "RFX (record field exchange), record views", "record views, data exchange", "DDX (dialog data exchange), record views", "RFX (record field exchange)"] -ms.assetid: abc52ca7-6997-47a7-98f3-f347f52b1f72 --- -# Data Exchange for Record Views (MFC Data Access) +# Data Exchange for Record Views (MFC Data Access) When you use [Add Class](../mfc/reference/adding-an-mfc-odbc-consumer.md) to map the controls in a record view's dialog template resource to the fields of a recordset, the framework manages data exchange in both directions — from recordset to controls and from controls to recordset.

Because `CException` has an inherited private copy constructor, the class and its derivatives aren't copyable, and can't be passed by value, which also means they can't be caught by value. Catch statements that caught MFC exceptions by value previously led to uncaught exceptions at runtime. Now the compiler correctly identifies this situation and reports error C2316. To fix this issue, we recommend you use the MFC TRY/CATCH macros rather than write your own exception handlers. If that's not appropriate for your code, catch MFC exceptions by reference instead. ## Example -The following sample generates C2316, and shows a way to fix it: +The following example generates C2316, and shows a way to fix it: ```cpp // C2316.cpp diff --git a/docs/error-messages/compiler-errors-1/compiler-error-c2317.md b/docs/error-messages/compiler-errors-1/compiler-error-c2317.md index 79f823cb0e5..fc575b588a1 100644 --- a/docs/error-messages/compiler-errors-1/compiler-error-c2317.md +++ b/docs/error-messages/compiler-errors-1/compiler-error-c2317.md @@ -1,18 +1,21 @@ --- -description: "Learn more about: Compiler Error C2317" title: "Compiler Error C2317" -ms.date: "11/04/2016" +description: "Learn more about: Compiler Error C2317" +ms.date: 11/04/2016 f1_keywords: ["C2317"] helpviewer_keywords: ["C2317"] -ms.assetid: e44d129b-8d3e-4ce9-9d79-6791ee77f25e --- # Compiler Error C2317 -'try' block starting on line 'number' has no catch handlers +> 'try' block starting on line 'number' has no catch handlers + +## Remarks A **`try`** block must have at least one catch handler. -The following sample generates C2317: +## Example + +The following example generates C2317: ```cpp // C2317.cpp diff --git a/docs/error-messages/compiler-errors-1/compiler-error-c2318.md b/docs/error-messages/compiler-errors-1/compiler-error-c2318.md index b5482c8358f..5a67e8cb5a3 100644 --- a/docs/error-messages/compiler-errors-1/compiler-error-c2318.md +++ b/docs/error-messages/compiler-errors-1/compiler-error-c2318.md @@ -1,18 +1,21 @@ --- -description: "Learn more about: Compiler Error C2318" title: "Compiler Error C2318" -ms.date: "11/04/2016" +description: "Learn more about: Compiler Error C2318" +ms.date: 11/04/2016 f1_keywords: ["C2318"] helpviewer_keywords: ["C2318"] -ms.assetid: 169e30b9-df78-46cb-90bf-576ad3c32fd4 --- # Compiler Error C2318 -no try block associated with this catch handler +> no try block associated with this catch handler + +## Remarks A **`catch`** handler is defined but not preceded by a **`try`** block. -The following sample generates C2318: +## Example + +The following example generates C2318: ```cpp // C2318.cpp diff --git a/docs/error-messages/compiler-errors-1/compiler-error-c2319.md b/docs/error-messages/compiler-errors-1/compiler-error-c2319.md index 0a9d1381842..87a4c1537f5 100644 --- a/docs/error-messages/compiler-errors-1/compiler-error-c2319.md +++ b/docs/error-messages/compiler-errors-1/compiler-error-c2319.md @@ -1,18 +1,21 @@ --- -description: "Learn more about: Compiler Error C2319" title: "Compiler Error C2319" -ms.date: "11/04/2016" +description: "Learn more about: Compiler Error C2319" +ms.date: 11/04/2016 f1_keywords: ["C2319"] helpviewer_keywords: ["C2319"] -ms.assetid: 25263e6e-f5ba-4d2c-8727-8c2d8ca2e5ce --- # Compiler Error C2319 -'try/catch' must be followed by a compound statement.

If the compiler file listed has a utc or C2 path segment, it is probably an optimization error. If the file has a cxxfe or c1xx path segment, or is msc1.cpp, it is probably a parser error. If the file named is cl.exe, there is no other information available. You can often fix an optimization problem by removing one or more optimization options. To determine which option is at fault, remove options one at a time and recompile until the error message goes away. The options most commonly responsible are [/Og (Global optimizations)](../../build/reference/og-global-optimizations.md) and [/Oi (Generate Intrinsic Functions)](../../build/reference/oi-generate-intrinsic-functions.md). Once you determine which optimization option is responsible, you can disable it around the function where the error occurs by using the [optimize](../../preprocessor/optimize.md) pragma, and continue to use the option for the rest of the module. For more information about optimization options, see [Optimization best practices](../../build/optimization-best-practices.md). diff --git a/docs/error-messages/compiler-errors-1/fatal-error-c1002.md b/docs/error-messages/compiler-errors-1/fatal-error-c1002.md index c001659abf6..d254d4e5ced 100644 --- a/docs/error-messages/compiler-errors-1/fatal-error-c1002.md +++ b/docs/error-messages/compiler-errors-1/fatal-error-c1002.md @@ -1,14 +1,15 @@ --- -description: "Learn more about: Fatal Error C1002" title: "Fatal Error C1002" -ms.date: "11/04/2016" +description: "Learn more about: Fatal Error C1002" +ms.date: 11/04/2016 f1_keywords: ["C1002"] helpviewer_keywords: ["C1002"] -ms.assetid: bd6d274a-c7b4-43af-8bf2-23c5e442aa22 --- # Fatal Error C1002 -compiler is out of heap space in pass 2 +> compiler is out of heap space in pass 2 + +## Remarks The compiler ran out of dynamic memory space during its second pass, probably due to a program with too many symbols or complex expressions. diff --git a/docs/error-messages/compiler-errors-1/fatal-error-c1003.md b/docs/error-messages/compiler-errors-1/fatal-error-c1003.md index 651a5259eac..453e163d0d4 100644 --- a/docs/error-messages/compiler-errors-1/fatal-error-c1003.md +++ b/docs/error-messages/compiler-errors-1/fatal-error-c1003.md @@ -1,13 +1,14 @@ --- -description: "Learn more about: Fatal Error C1003" title: "Fatal Error C1003" -ms.date: "11/04/2016" +description: "Learn more about: Fatal Error C1003" +ms.date: 11/04/2016 f1_keywords: ["C1003"] helpviewer_keywords: ["C1003"] -ms.assetid: 27d2d009-2e0f-41fb-8bfc-372752fbe920 --- # Fatal Error C1003 -error count exceeds number; stopping compilation +> error count exceeds number; stopping compilation + +## Remarks Errors in the program are too numerous to allow recovery.

When a derived class overrides a public base class, it may return a pointer or reference to the derived class instead of a base-class pointer or reference.

If the objects are of the same type, consider use of a single static array of that type, and reference individual members as required. diff --git a/docs/error-messages/compiler-errors-2/compiler-error-c2605.md b/docs/error-messages/compiler-errors-2/compiler-error-c2605.md index a11f99a7a35..ee73a6aa642 100644 --- a/docs/error-messages/compiler-errors-2/compiler-error-c2605.md +++ b/docs/error-messages/compiler-errors-2/compiler-error-c2605.md @@ -1,20 +1,21 @@ --- -description: "Learn more about: Compiler Error C2605" title: "Compiler Error C2605" -ms.date: "11/04/2016" +description: "Learn more about: Compiler Error C2605" +ms.date: 11/04/2016 f1_keywords: ["C2605"] helpviewer_keywords: ["C2605"] -ms.assetid: a0e6f132-5acf-4e19-b277-ddf196d182bf --- # Compiler Error C2605 -'name' : this method is reserved within a managed or WinRT class +> 'name' : this method is reserved within a managed or WinRT class + +## Remarks Certain names are reserved by the compiler for internal functions.

It can also happen if you set specific compiler options for individual source files. To resolve this error, regenerate the precompiled header by using the specified command-line option. To regenerate the precompiled header, build the associated source file. For example, projects created by a Visual Studio template usually create a source file named *`pch.cpp`* to generate the precompiled header. (In older versions of Visual Studio, this file is named *`stdafx.cpp`*.) In other projects, the source file to rebuild is the one built by using the [`/Yc` (Create precompiled header file)](../../build/reference/yc-create-precompiled-header-file.md) compiler option.

In other source files compiled by using the **/Yu**filename option to use the PCH file, an include of *filename* must be the first non-comment line in the file.

When you use a placement new expression, the compiler looks for a matching `operator delete` function that takes the same parameters (after the first one). If one is found and its signature matches a usual deallocation function, the compiler reports error C2956. diff --git a/docs/error-messages/compiler-errors-2/compiler-error-c2957.md b/docs/error-messages/compiler-errors-2/compiler-error-c2957.md index e2d17ce3dd2..2c1e921c6a3 100644 --- a/docs/error-messages/compiler-errors-2/compiler-error-c2957.md +++ b/docs/error-messages/compiler-errors-2/compiler-error-c2957.md @@ -1,18 +1,21 @@ --- -description: "Learn more about: Compiler Error C2957" title: "Compiler Error C2957" -ms.date: "11/04/2016" +description: "Learn more about: Compiler Error C2957" +ms.date: 11/04/2016 f1_keywords: ["C2957"] helpviewer_keywords: ["C2957"] -ms.assetid: 9cb4526f-4af8-47e9-b786-56192627ca72 --- # Compiler Error C2957 -'delim' : invalid left delimiter : expected '<' +> 'delim' : invalid left delimiter : expected '<' + +## Remarks A generic class was ill formed. -The following sample generates C2957: +## Example + +The following example generates C2957: ```cpp // C2957.cpp diff --git a/docs/error-messages/compiler-errors-2/compiler-error-c2958.md b/docs/error-messages/compiler-errors-2/compiler-error-c2958.md index 72706383992..341ff3c1dd6 100644 --- a/docs/error-messages/compiler-errors-2/compiler-error-c2958.md +++ b/docs/error-messages/compiler-errors-2/compiler-error-c2958.md @@ -1,14 +1,15 @@ --- -description: "Learn more about: Compiler Error C2958" title: "Compiler Error C2958" -ms.date: "11/04/2016" +description: "Learn more about: Compiler Error C2958" +ms.date: 11/04/2016 f1_keywords: ["C2958"] helpviewer_keywords: ["C2958"] -ms.assetid: 332bf6d3-7cd1-4b1a-8ddb-d4a8cbf01115 --- # Compiler Error C2958 -the left delimiter found at 'location' was not matched correctly +> the left delimiter found at 'location' was not matched correctly + +## Remarks A delimiter is not properly matched. diff --git a/docs/error-messages/compiler-errors-2/compiler-error-c2959.md b/docs/error-messages/compiler-errors-2/compiler-error-c2959.md index 6855bf67bb9..af70755a70c 100644 --- a/docs/error-messages/compiler-errors-2/compiler-error-c2959.md +++ b/docs/error-messages/compiler-errors-2/compiler-error-c2959.md @@ -1,20 +1,21 @@ --- -description: "Learn more about: Compiler Error C2959" title: "Compiler Error C2959" -ms.date: "11/04/2016" +description: "Learn more about: Compiler Error C2959" +ms.date: 11/04/2016 f1_keywords: ["C2959"] helpviewer_keywords: ["C2959"] -ms.assetid: d66bb2a8-70c3-4209-a358-b0c47f111a50 --- # Compiler Error C2959 -a generic class or function may not be a member of a template +> a generic class or function may not be a member of a template + +## Remarks For more information, see [Windows Runtime and Managed Templates](../../extensions/windows-runtime-and-managed-templates-cpp-component-extensions.md) and [Generics](../../extensions/generics-cpp-component-extensions.md). ##

Pointer-to-member now requires a qualified name and the address-of operator (&). C4407 can occur if you cast between a multiple inheritance pointer-to-member to a single inheritance pointer-to-member. Sometimes this can work, but sometimes it can't because the single inheritance pointer-to-member representation doesn't hold sufficient information. Compiling with the **`/vmm`** might help. For more information, see [`/vmm`, `/vms`, `/vmv` (General purpose representation)](../../build/reference/vmm-vms-vmv-general-purpose-representation.md).

You can use Unicode [escape sequences](../../c-language/escape-sequences.md) to create characters or strings that use only the basic ANSI character set in your source code.

Because it's greater than the maximum **`int`** value of 2147483647, but still fits in an **`unsigned int`**, the type of 2147483648 is **`unsigned int`**. 1. Unary minus is applied to the unsigned value, with an unsigned result, which also happens to be 2147483648. The unsigned type of the result can cause unexpected behavior. If the result is used in a comparison, then an unsigned comparison might be used, for example, when the other operand is an **`int`**. -You can avoid C4146 by using `INT_MIN` or `LLONG_MIN` from *``* or the C++ equivalent, *``*.

Code is sometimes written that uses parent directory relative paths to include headers from external libraries. When these parent directory-relative header paths are specified in source files, it creates a risk: The program could be compiled by including a different header file than the programmer intends. These relative paths may not be portable to other developers' build environments. Instead, we recommend you specify the paths to such headers in the build environment, such as in the `INCLUDE` environment variable or in parameters to the [`/I` (Additional include directories)](../../build/reference/i-additional-include-directories.md) compiler option. In the Visual Studio IDE, you can set the paths in your project's **Configuration Properties** > **C/C++** > **General** property page, in the **Additional Include Directories** property. Although there's no specific warning for it, we also don't recommend use of parent directory path segments when you specify your project's include directories. diff --git a/docs/error-messages/compiler-warnings/compiler-warning-level-4-c4471.md b/docs/error-messages/compiler-warnings/compiler-warning-level-4-c4471.md index 958561ae411..fdba3fbfe5b 100644 --- a/docs/error-messages/compiler-warnings/compiler-warning-level-4-c4471.md +++ b/docs/error-messages/compiler-warnings/compiler-warning-level-4-c4471.md @@ -1,14 +1,15 @@ --- -description: "Learn more about: Compiler Warning (level 4) C4471" title: "Compiler Warning (level 4) C4471" -ms.date: "04/24/2017" +description: "Learn more about: Compiler Warning (level 4) C4471" +ms.date: 04/24/2017 f1_keywords: ["C4471"] helpviewer_keywords: ["C4471"] -ms.assetid: ccfd8bd5-bc1b-4be7-a6ea-0e3a7add6607 --- # Compiler Warning (level 4) C4471 -'*enumeration*': a forward declaration of an unscoped enumeration must have an underlying type (int assumed) +> '*enumeration*': a forward declaration of an unscoped enumeration must have an underlying type (int assumed) + +## Remarks A forward declaration of an unscoped enumeration was found without a specifier for the underlying type.

If the tools make the wrong assumption, later errors or warnings may not apply to your project. When you correct issues in your project, always start with the first error or warning that's reported, and rebuild often. One fix may resolve multiple subsequent errors. To get help on a particular diagnostic message in Visual Studio, select it in the **Output** window and press the **F1** key. Visual Studio opens the documentation page for that error, if one exists. You can also use the search tool at the top of the page to find articles about specific errors or warnings. Or, browse the list of errors and warnings by tool and type in the table of contents on this page. > [!NOTE] -> Not every Visual Studio error or warning is documented. In many cases, the diagnostic message provides all of the information that's available. If you landed on this page when you used **F1** and you think the error or warning message needs additional explanation, let us know. You can use the feedback buttons on this page to raise a documentation issue on [GitHub](https://github.com/MicrosoftDocs/cpp-docs/issues). If you think the error or warning is wrong, or you've found another problem with the toolset, report a product issue on the [Developer Community](https://aka.ms/feedback/report?space=62) site. You can also send feedback and enter bugs within the IDE. In Visual Studio, go to the menu bar and choose **Help > Send Feedback > Report a Problem**, or submit a suggestion by using **Help > Send Feedback > Send a Suggestion**.

You may want to break up how response files are generated and consumed by your build system, for instance, by generating some code as static libraries. diff --git a/docs/error-messages/tool-errors/linker-tools-error-lnk1179.md b/docs/error-messages/tool-errors/linker-tools-error-lnk1179.md index 6b95e3bc95d..9007d33d95c 100644 --- a/docs/error-messages/tool-errors/linker-tools-error-lnk1179.md +++ b/docs/error-messages/tool-errors/linker-tools-error-lnk1179.md @@ -1,14 +1,15 @@ --- -description: "Learn more about: Linker Tools Error LNK1179" title: "Linker Tools Error LNK1179" -ms.date: "11/04/2016" +description: "Learn more about: Linker Tools Error LNK1179" +ms.date: 11/04/2016 f1_keywords: ["LNK1179"] helpviewer_keywords: ["LNK1179"] -ms.assetid: 4b1536d7-0d3d-4f29-a9c1-6fa5cf6cb665 --- # Linker Tools Error LNK1179 -invalid or corrupt file: duplicate COMDAT 'filename' +> invalid or corrupt file: duplicate COMDAT 'filename' + +## Remarks An object module contains two or more COMDATs with the same name. diff --git a/docs/error-messages/tool-errors/linker-tools-error-lnk1181.md b/docs/error-messages/tool-errors/linker-tools-error-lnk1181.md index 0a8bdc45693..3212fbf52a1 100644 --- a/docs/error-messages/tool-errors/linker-tools-error-lnk1181.md +++ b/docs/error-messages/tool-errors/linker-tools-error-lnk1181.md @@ -1,14 +1,15 @@ --- -description: "Learn more about: Linker Tools Error LNK1181" title: "Linker Tools Error LNK1181" -ms.date: "08/22/2018" +description: "Learn more about: Linker Tools Error LNK1181" +ms.date: 08/22/2018 f1_keywords: ["LNK1181"] helpviewer_keywords: ["LNK1181"] -ms.assetid: 984b0db6-e331-4284-b2a7-a212fe96c486 --- # Linker Tools Error LNK1181 -cannot open input file 'filename' +> cannot open input file 'filename' + +## Remarks The linker could not find `filename` because it does not exist or the path was not found. diff --git a/docs/error-messages/tool-errors/linker-tools-error-lnk1188.md b/docs/error-messages/tool-errors/linker-tools-error-lnk1188.md index f5800616ee0..fa68aa2479c 100644 --- a/docs/error-messages/tool-errors/linker-tools-error-lnk1188.md +++ b/docs/error-messages/tool-errors/linker-tools-error-lnk1188.md @@ -1,13 +1,14 @@ --- -description: "Learn more about: Linker Tools Error LNK1188" title: "Linker Tools Error LNK1188" -ms.date: "11/04/2016" +description: "Learn more about: Linker Tools Error LNK1188" +ms.date: 11/04/2016 f1_keywords: ["LNK1188"] helpviewer_keywords: ["LNK1188"] -ms.assetid: 4af574b0-5b41-4580-9a37-52a634add995 --- # Linker Tools Error LNK1188 -BADFIXUPSECTION:: invalid fixup target 'symbol'; possible zero length section +> BADFIXUPSECTION:: invalid fixup target 'symbol'; possible zero length section + +## Remarks During a VxD link, the target of a relocation did not have a section.

Some intrinsics, such as **`__assume`** and `__ReadWriteBarrier`, provide information to the compiler, which affects the behavior of the optimizer. diff --git a/docs/intrinsics/debugbreak.md b/docs/intrinsics/debugbreak.md index 4b752926d38..ed576d932d1 100644 --- a/docs/intrinsics/debugbreak.md +++ b/docs/intrinsics/debugbreak.md @@ -1,10 +1,9 @@ --- -description: "Learn more about: __debugbreak" title: "__debugbreak" -ms.date: "09/02/2019" +description: "Learn more about: __debugbreak" +ms.date: 09/02/2019 f1_keywords: ["__debugbreak_cpp", "__debugbreak"] helpviewer_keywords: ["breakpoints, __debugbreak intrinsic", "__debugbreak intrinsic"] -ms.assetid: 1d1e1c0c-891a-4613-ae4b-d790094ba830 --- # __debugbreak @@ -34,7 +33,7 @@ The `__debugbreak` compiler intrinsic, similar to [DebugBreak](/windows/win32/ap For example: ```C -main() { +int main() { __debugbreak();

Through this interface, the container can ask to create (and possibly enumerate) the views that the active document can display.

These classes provide a convenient C++ member function interface to the structures in Windows that they encapsulate. For more about using these classes, see [Window Object Topics](window-objects.md).

The collections are dynamically sized. These classes can be used in any program, whether written for Windows or not. However, they are most useful for implementing the data structures that define your document classes in the application framework. You can readily derive specialized collection classes from these, or you can create them based on the template classes. For more information about these approaches, see the article [Collections](collections.md). For a list of the template collection classes, see the article [Template Classes for Arrays, Lists, and Maps](template-classes-for-arrays-lists-and-maps.md). Arrays are one-dimensional data structures that are stored contiguously in memory. They support very fast random access since the memory address of any given element can be calculated by multiplying the index of the element by the size of an element and adding the result to the base address of the array. But arrays are very expensive if you have to insert elements into the array, since the entire array past the element inserted has to be moved to make room for the element to be inserted. Arrays can grow and shrink as necessary. diff --git a/docs/mfc/asynchronous-monikers-on-the-internet.md b/docs/mfc/asynchronous-monikers-on-the-internet.md index f9ea5ad99cd..0387ba229f9 100644 --- a/docs/mfc/asynchronous-monikers-on-the-internet.md +++ b/docs/mfc/asynchronous-monikers-on-the-internet.md @@ -3,10 +3,12 @@ description: "Learn more about: Asynchronous Monikers on the Internet" title: "Asynchronous Monikers on the Internet" ms.date: "11/04/2016" helpviewer_keywords: ["ActiveX controls [MFC], asynchronous", "MFC, asynchronous monikers", "asynchronous monikers [MFC]", "Web applications [MFC], asynchronous", "downloading Internet resources and asynchronous monikers", "optimization [MFC], asynchronous downloading across Internet", "Internet [MFC], asynchronous downloading"] -ms.assetid: 418b0c64-0046-4dae-8118-c9c762b5822e --- # Asynchronous Monikers on the Internet +>[!NOTE] +> The Microsoft Foundation Classes (MFC) library continues to be supported.

One of the important members of **CHARFORMAT** is **dwMask**. In `SetSelectionCharFormat` and `SetWordCharFormat`, **dwMask** specifies which character attributes will be set by this function call. `GetSelectionCharFormat` reports the attributes of the first character in the selection; **dwMask** specifies the attributes that are consistent throughout the selection. diff --git a/docs/mfc/class-library-overview.md b/docs/mfc/class-library-overview.md index f30e76f9ec3..95f1076e12d 100644 --- a/docs/mfc/class-library-overview.md +++ b/docs/mfc/class-library-overview.md @@ -4,10 +4,13 @@ title: "Class Library Overview" ms.date: "09/17/2019" f1_keywords: ["vc.classes.mfc"] helpviewer_keywords: ["grouping MFC classes", "MFC, class library", "classes [MFC], MFC", "class libraries, MFC", "class libraries"] -ms.assetid: 9b0e3152-ac39-4f52-91b4-f20aa3a674aa +ms.topic: concept-article --- # Class Library Overview +>[!NOTE] +> The Microsoft Foundation Classes (MFC) library continues to be supported.

These classes abstract the Internet protocols for HTTP, FTP, and gopher into a high-level application programming interface, providing a fast and straightforward path to making applications Internet-aware.

When your application runs, most of the flow of control resides in the framework's code. The framework manages the message loop that gets messages from Windows as the user chooses commands and edits data in a view. Events that the framework can handle by itself do not rely on your code at all. For example, the framework knows how to close windows and how to exit the application in response to user commands. As it handles these tasks, the framework uses message handlers and C++ virtual functions to give you opportunities to respond to these events as well. Your code is not in control, however; the framework is. The framework calls your code for application-specific events. For example, when the user chooses a menu command, the framework routes the command along a sequence of C++ objects: the current view and frame window, the document associated with the view, the document's document template, and the application object. If one of these objects can handle the command, it does so, calling the appropriate message-handler function.

Just one option in the Application Wizard supports both. When a status bar is present, the application automatically provides helpful feedback as the user moves the pointer over items on the menus. The application automatically displays a prompt string in the status bar when the menu item is highlighted. For example, when the user moves the pointer over the **Cut** command on the **Edit** menu, the status bar might display "Cuts the selection and puts it on the Clipboard" in the message area of the status bar. The prompt helps the user understand the purpose of the menu item. This also works when the user clicks a toolbar button. You can add to this status-bar help by defining prompt strings for menu items that you add to the program. To do this, provide the prompt strings when you edit the properties of the menu item in the menu editor.

These include flat toolbars, toolbars with hot images, large icons, pager buttons, locked toolbars, rebar controls, text under images, background images, and tabbed toolbars. The `CMFCToolBar` class also contains built-in support for user customization of toolbars and menus, drag-and-drop between toolbars and menus, combo box buttons, edit box buttons, color pickers, and roll-up buttons.

The difference between the size of your structure and the size of the `TCITEMHEADER` structure should equal the number of extra bytes per tab. ### Example diff --git a/docs/mfc/reference/ctabview-class.md b/docs/mfc/reference/ctabview-class.md index b084e0afbd3..2a38b3edd1b 100644 --- a/docs/mfc/reference/ctabview-class.md +++ b/docs/mfc/reference/ctabview-class.md @@ -1,13 +1,15 @@ --- -description: "Learn more about: CTabView Class" title: "CTabView Class" -ms.date: "11/04/2016" +description: "Learn more about: CTabView Class" +ms.date: 11/04/2016 f1_keywords: ["CTabView", "AFXTABVIEW/CTabView", "AFXTABVIEW/CTabView::AddView", "AFXTABVIEW/CTabView::FindTab", "AFXTABVIEW/CTabView::GetActiveView", "AFXTABVIEW/CTabView::GetTabControl", "AFXTABVIEW/CTabView::RemoveView", "AFXTABVIEW/CTabView::SetActiveView", "AFXTABVIEW/CTabView::IsScrollBar", "AFXTABVIEW/CTabView::OnActivateView"] helpviewer_keywords: ["CTabView [MFC], AddView", "CTabView [MFC], FindTab", "CTabView [MFC], GetActiveView", "CTabView [MFC], GetTabControl", "CTabView [MFC], RemoveView", "CTabView [MFC], SetActiveView", "CTabView [MFC], IsScrollBar", "CTabView [MFC], OnActivateView"] -ms.assetid: 8e6ecd9d-d28d-432b-8ec8-0446f0204d52 --- # CTabView Class +>[!NOTE] +> The Microsoft Foundation Classes (MFC) library continues to be supported.

The more laborious manual approach is to call functions such as the `SetDlgItemText` and `GetDlgItemText` member functions of class `CWnd`, which apply to control windows. With these functions, you access each control individually to set or get its value, calling functions such as `SetWindowText` and `GetWindowText`. The framework's approach automates both initialization and retrieval. Dialog data exchange (DDX) lets you exchange data between the controls in the dialog box and member variables in the dialog object more easily. This exchange works both ways. To initialize the controls in the dialog box, you can set the values of data members in the dialog object, and the framework will transfer the values to the controls before the dialog box is displayed.

Later, the object can be re-created by reading, or "deserializing," the object's state from persistent storage. A key point here is that the object itself is responsible for reading and writing its own state. Thus, for a class to be persistent, it must implement the basic serialization operations. The framework provides a default implementation for saving documents to disk files in response to the Save and Save As commands on the File menu and for loading documents from disk files in response to the Open command.

The Visual Studio graphics editor and the Windows File Manager are examples of programs that use this splitter style. This style of splitter window does not use splitter boxes. In "dynamic splitters," additional panes are created and destroyed as the user splits and un-splits new views. This splitter starts out with a single view and provides splitter boxes for the user to initiate splitting. The splitter window dynamically creates a new view object when the view is split in one direction. This new view object represents the new pane. If the view is split in two directions by using the keyboard interface, the splitter window creates three new view objects for the three new panes. While the split is active, Windows displays the splitter box as a splitter bar between the panes. Windows destroys additional view objects when the user removes a split, but the original view remains until the splitter window itself is destroyed. Microsoft Excel and Microsoft Word are examples of applications that use the dynamic splitter style. diff --git a/docs/mfc/tn030-customizing-printing-and-print-preview.md b/docs/mfc/tn030-customizing-printing-and-print-preview.md index 851f9d6ad6d..859df12533e 100644 --- a/docs/mfc/tn030-customizing-printing-and-print-preview.md +++ b/docs/mfc/tn030-customizing-printing-and-print-preview.md @@ -4,10 +4,12 @@ title: "TN030: Customizing Printing and Print Preview" ms.date: "06/28/2018" f1_keywords: ["vc.print"] helpviewer_keywords: ["TN030", "customizing printing and print preview", "printing [MFC], views", "printing views [MFC]", "print preview [MFC], customizing"] -ms.assetid: 32744697-c91c-41b6-9a12-b8ec01e0d438 --- # TN030: Customizing Printing and Print Preview +>[!NOTE] +> The Microsoft Foundation Classes (MFC) library continues to be supported.

Making direct DAO calls to the methods of an MFC-managed DAO object should require only a few lines of code.

With the introduction of windowless activation, this distinction is no longer universal, but still applies to many controls. Compared with the rest of the initialization typically performed by an ActiveX control, the creation of a window is an extremely expensive operation. Ideally, a control would defer creating its window until absolutely necessary. diff --git a/docs/mfc/two-ways-to-create-a-carchive-object.md b/docs/mfc/two-ways-to-create-a-carchive-object.md index 9347fd20f75..b63004007b1 100644 --- a/docs/mfc/two-ways-to-create-a-carchive-object.md +++ b/docs/mfc/two-ways-to-create-a-carchive-object.md @@ -3,10 +3,12 @@ description: "Learn more about: Two Ways to Create a CArchive Object" title: "Two Ways to Create a CArchive Object" ms.date: "11/04/2016" helpviewer_keywords: ["CArchive class [MFC], closing CArchive objects", "CArchive objects [MFC], closing", "I/O [MFC], creating CArchive objects", "serialization [MFC], CArchive class", "CArchive objects [MFC]", "storage [MFC], CArchive class [MFC]", "data storage [MFC], CArchive class", "CArchive class [MFC], constructor"] -ms.assetid: aefa28ce-b55c-40dc-9e42-5f038030985d --- # Two Ways to Create a CArchive Object +>[!NOTE] +> The Microsoft Foundation Classes (MFC) library continues to be supported.

A status bar — a window object of class [CStatusBar](../mfc/reference/cstatusbar-class.md) — contains several "panes." Each pane is a rectangular area of the status bar that you can use to display information. For example, many applications display the status of the CAPS LOCK, NUM LOCK, and other keys in the rightmost panes. Applications also often display informative text in the leftmost pane (pane 0), sometimes called the "message pane." For example, the default MFC status bar uses the message pane to display a string explaining the currently selected menu item or toolbar button. The figure in [Status Bars](../mfc/status-bar-implementation-in-mfc.md) shows a status bar from an Application Wizard-created MFC application. By default, MFC does not enable a `CStatusBar` pane when it creates the pane. To activate a pane, you must use the ON_UPDATE_COMMAND_UI macro for each pane on the status bar and update the panes. Because panes do not send WM_COMMAND messages (they aren't like toolbar buttons), you must type the code manually. diff --git a/docs/mfc/upgrading-an-existing-activex-control.md b/docs/mfc/upgrading-an-existing-activex-control.md index e2b88e3db99..5af223c224e 100644 --- a/docs/mfc/upgrading-an-existing-activex-control.md +++ b/docs/mfc/upgrading-an-existing-activex-control.md @@ -3,10 +3,13 @@ description: "Learn more about: Upgrading an Existing ActiveX Control" title: "Upgrading an Existing ActiveX Control" ms.date: 11/03/2021 helpviewer_keywords: ["ActiveX controls [MFC], Internet", "LPK files for Internet controls", "safe for scripting and initialization (controls)", "OLE controls [MFC], upgrading to ActiveX", "CAB files, for ActiveX controls", "Internet applications [MFC], ActiveX controls", "Internet applications [MFC], packaging code for download", "upgrading ActiveX controls", "licensing ActiveX controls"] -ms.assetid: 4d12ddfa-b491-4f9f-a0b7-b51458e05651 +ms.topic: how-to --- # Upgrading an Existing ActiveX Control +>[!NOTE] +> The Microsoft Foundation Classes (MFC) library continues to be supported.

The `CWnd` object is a C++ window object, distinct from the `HWND` that represents a Windows window but containing it. Use `CWnd` to derive your own child window classes, or use one of the many MFC classes derived from `CWnd`. Class `CWnd` is the base class for all windows, including frame windows, dialog boxes, child windows, controls, and control bars such as toolbars.

MFC provides some default functionality and management of windows, but you can derive your own class from `CWnd` and use its member functions to customize the provided functionality.

This release focuses on compile-time evaluation improvements, Unicode support enhancements, and refined `consteval` handling. + +This version shipped first with Visual Studio 2026 version 18.6 and includes version 19.51 of the MSVC compiler. + +Key highlights of this release include: +- Static `constexpr` variables in `constexpr` functions (P2647R1) +- Relaxed `constexpr` restrictions (P2448R2) +- Unicode support improvements (P2029R4, P2071R2, P2314R4) +- Improved `consteval` function handling with default-enabled experimental features +- New standard library headers `` and `` + +For more information about library features and other updates, see [C++23 Support in MSVC Build Tools 14.51](https://devblogs.microsoft.com/cppblog/c23-support-in-msvc-build-tools-14-51) and [STL Changelog](https://github.com/microsoft/STL/wiki/Changelog). + +### P2647R1: Static constexpr variables in constexpr functions + +[P2647R1](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p2647r1.html) allows static local variables to be declared `constexpr` within `constexpr` functions, reducing friction when marking existing functions as `constexpr`. + +```cpp +constexpr char xdigit(int n) +{ + static constexpr char digits[] = "0123456789abcdef"; + return digits[n]; +} +``` + +This feature improves both compile-time evaluation and run-time optimization. Previously, static local variables couldn't be marked `constexpr`, which made it difficult to declare lookup tables inside `constexpr` functions. Now the compiler can evaluate these functions at compile time when possible, while also generating optimized run-time code that accesses the static storage directly. + +### Other C++23 features + +Other C++23 features implemented in this release include Unicode support improvements, labels at the end of compound statements for C compatibility, Class Template Argument Deduction (CTAD) from inherited constructors, and meaningful exports for modules. For more information and related Core Working Group (CWG) issue resolutions, see the [C++23 Support in MSVC Build Tools 14.51](https://devblogs.microsoft.com/cppblog/c23-support-in-msvc-build-tools-14-51). + +### Standard Library + +MSVC Build Tools v14.51 adds new standard library features including: +- `` and `` headers +- Type traits for detecting references binding to temporaries ([P2255R2](https://wg21.link/p2255r2)) +- Explicit lifetime management ([P2590R2](https://wg21.link/p2590r2)), and `is_implicit_lifetime` ([P2674R1](https://wg21.link/P2674R1)). +- Major `` overhaul, SIMD-vectorized STL algorithms using NEON for ARM64/ARM64EC, and 18 Library Working Group (LWG) issue resolutions. +For the complete list, see the [STL Changelog](https://github.com/microsoft/STL/wiki/Changelog). + +## C++ conformance improvements, behavior changes, and bug fixes in MSVC Build Tools v14.50 + +MSVC Build Tools v14.50 introduces improvements to the MSVC compiler and standard library including better C++23 standards conformance, enhanced reliability, and improved correctness. This release also includes numerous bug fixes and updates that benefit large-scale C++ development. + +This version shipped first with Visual Studio 2026 version 18.0 and includes version 19.50 of the MSVC compiler. + +Key highlights of this release include: +- Advanced C++23 feature support including `auto(x)` decay-copy and `#warning` directive. +- Comprehensive `constexpr` improvements, particularly for virtual functions. +- Major stability improvements for C++ modules. +- Extensive reliability fixes reducing internal compiler errors. +- Enhanced C++/CLI support for managed code scenarios. +- The Microsoft C++ standard library (MSVC STL) no longer supports targeting Windows 7/Server 2008 R2, Windows 8/Server 2012, or Windows 8.1/Server 2012 R2. +- Windows 10/Server 2016 are the minimum supported operating systems. + +For more information about performance improvements, bug fixes, and conformance updates in the standard library, see [STL Changelog](https://github.com/microsoft/STL/wiki/Changelog), which is updated regularly. + +## C++23 features + +MSVC Build Tools v14.50 adds support for several C++23 features, bringing the compiler closer to full C++23 conformance. + +### P0849R8: auto(x) - decay-copy in the language + +[P0849R8](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p0849r8.html) introduces the `auto(x)` syntax for decay-copy operations directly in the language, providing a more concise way to express decay-copy semantics. + +Before P0849R8, you needed to explicitly perform decay operations: + +```cpp +// Before P0849R8: +void pop_front_alike(auto& x) +{ + using T = std::decay_t; + std::erase(x, T(x.front())); +} +``` + +After P0849R8, you can use the simpler `auto(x)` syntax: + +```cpp +// After P0849R8: +void pop_front_alike(auto& x) +{ + std::erase(x, auto(x.front())); +} +``` + +This feature provides a standardized way to perform decay-copy operations, making code more readable and reducing the need for verbose template metaprogramming. + +### P2437R1: C++23 `#warning` directive + +[P2437R1](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p2437r1.pdf) implements the C++23 `#warning` preprocessor directive, providing a standard way to emit warnings during compilation. + +```cpp +// Valid before C++23. +#error bad configuration... + +// Valid after C++23. +#warning configuration deprecated... +``` + +The `#warning` directive allows you to emit diagnostic messages without stopping compilation, making it useful for deprecation notices and configuration warnings. For more information, see [#warning directive (C/C++)](/cpp/preprocessor/hash-warning-directive-c-cpp). + +### CWG Issue 2586: Explicit object parameter for assignment and comparison + +[CWG Issue 2586](https://cplusplus.github.io/CWG/issues/2586) allows explicit object parameters in assignment and comparison operators, enabling more flexible operator definitions. + +```cpp +struct S +{ + S& operator=(this S&, const S&) = default; // Valid after CWG2586. + auto operator<=>(this const S&, const S&) = default; // Valid after CWG2586. +}; +``` + +This change allows you to use the explicit object parameter syntax (deducing `this`) in assignment and comparison operators, providing more consistent syntax across different types of member functions. + +### P2266R1 : Simpler implicit move + +The introduction of [P2266R1](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2266r1.html) may cause code that was previously treated as an lvalue to be treated as an xvalue or a prvalue. For example: + +```cpp +#include + +template +T& f(T&& t) +{ + return t; +} + +struct S { }; + +void g() +{ + S s1{ }; + S& s2 = f(std::move(s1)); +} +``` + +In C++20, and earlier, this code compiled because even though the type of `t` is `S&&` the use of `t` in `return t` is treated as a glvalue and so it can bind to the return type.\ +With C++23, `t` is treated as an xvalue and so it can't bind to an lvalue reference.\ +One fix is to change to the return type of the function from `T&` to `T&&` but this may affect code that calls this function. An alternative is to use the feature test macro that is associated with this change. For example: + +```cpp +#include + +template +T& f(T&& t) +{ +#if defined(__cpp_implicit_move) + return static_cast&>(t); +#else + return t; +#endif +} +``` + +Adding the cast means that the value-category of the return expression is now an lvalue and so it can bind to the return type. + +### P2280R4: References to unknown values during constant evaluation + +[P2280R4](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p2280r4.html) allows references to unknown values during constant evaluation, relaxing restrictions on `constexpr` evaluation. + +```cpp +template +constexpr size_t array_size(T (&)[N]) +{ + return N; +} + +void check(int const (¶m)[3]) +{ + constexpr auto s2 = array_size(param); // Previously ill-formed, now accepted as a constant expression after P2280R4. +} +``` + +This improvement allows more code to be evaluated at compile time, particularly when dealing with function parameters in template contexts. + +## Conformance enhancements + +Improved adherence to C++ standards includes better handling of attributes, templates, and C++20/C++23 features. + +### Attribute support + +- Added support for [`[[maybe_unused]]` on labels](https://developercommunity.visualstudio.com/t/unreferenced-label-when-ref-hidden-by-if/102076). +- Fixed warning C4102 (unreferenced label) when the only reference was from a discarded `if constexpr` branch. + +### Template and specialization fixes + +- [Diagnosed ill-formed friend explicit specializations](https://developercommunity.visualstudio.com/t/Defining-explicit-function-template-spec/10933841) that were incorrectly accepted in C++20 or later. +- Added `/Zc:enumEncoding` switch to [correctly encode enum nontype template parameters](https://developercommunity.visualstudio.com/t/Overload-resolution-fails-for-enum-non-t/10398088). +- Fixed issues with [missing 'template' keyword diagnostics](https://developercommunity.visualstudio.com/t/No-diagnostic-for-missing-template-in-d/10501221) + +### C++20 and C++23 Features + +- Enhanced [multidimensional `operator[]` support](https://developercommunity.visualstudio.com/t/Multidimensional-operator-with-Wall-r/10876026) +- Improved [concept and constraint evaluation](https://developercommunity.visualstudio.com/t/VS-1714-if-constexpr-requires--does/10905731) + +### Smaller conformance updates + +MSVC Build Tools v14.50 includes numerous smaller conformance improvements that enhance C++ standard compliance: + +- [CWG2635](https://cplusplus.github.io/CWG/issues/2635): Constrained structured bindings support +- [CWG2465](https://cplusplus.github.io/CWG/issues/2465): Coroutine parameters passed to promise constructor improvements +- [CWG2496](https://cplusplus.github.io/CWG/issues/2496): Ref-qualifiers and virtual overriding corrections +- [CWG2506](https://cplusplus.github.io/CWG/issues/2506): Structured bindings and array cv-qualifiers fixes +- [CWG2507](https://cplusplus.github.io/CWG/issues/2507): Default arguments for `operator[]` support +- [CWG2585](https://cplusplus.github.io/CWG/issues/2585): Behavior alignment with standard requirements +- [CWG2521](https://cplusplus.github.io/CWG/issues/2521): Deprecation of 'operator string-literal identifier' +- [CWG2528](https://cplusplus.github.io/CWG/issues/2528): Relaxed conversion rules for the spaceship operator +- [P2360R0](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2360r0.html): Extended init-statement definition to allow alias-declarations +- [P2290R3](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p2290r3.pdf): C++23 hexadecimal/octal delimited escape sequence support in string literals +- [P2797R0](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2023/p2797r0.html): Resolution for CWG2692 regarding static and explicit object member functions with the same parameter-type-lists +- [P2266R3](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p2266r3.html): Simpler implicit move semantics + +## Bug fixes + +Bug fixes for C++ Modules, `constexpr`, and other fixes were made in MSVC Build Tools v14.50. + +For a detailed list of bug fixes, see [Compiler Improvements in v14.50](https://devblogs.microsoft.com/cppblog/c-language-updates-in-msvc-build-tools-v14-50/#compiler-improvements-in-v14.50). + +**Encoding of certain nontype template arguments corrected** + +Affects `/std:c++20` or later. + +Certain nontype pointer type template arguments involving subobjects could lead to linking issues or in some cases silent bad code generation where what should be distinct specializations collide. + +```cpp +struct A +{ + int x;

In C++17, P0003R5 removed most dynamic exception specifications, except for one vestige: the standard deprecated `throw()` and requires it to behave as a synonym for **`noexcept`**.

It's likely that `throw()` will be removed in a future version of C++.

This setting enables the latest C++23 features and bug fixes. For more information, see [/std (Specify Language Standard Version)](../build/reference/std-specify-language-standard-version.md#stdc23preview). + - Support for C++23’s `size_t` literal suffix, which helps avoid truncations or signed comparison mismatches--especially when writing loops. For example: + ```cpp + // Infinite loop if v.size > max unsigned int + for (auto i = 0u; i < v.size(); ++i) + { + ... + } + + // Fixed because of uz literal + for (auto i = 0uz; i < v.size(); ++i) + { + ... + } + ``` + + - Support for vector lengths for code generation on x86 and x64. For more information, see [/vlen](../build/reference/vlen.md). + - Support for Intel Advanced Vector Extensions 10 version 1. For more information about `/arch:AVX10.1`, see [/arch (x64)](../build/reference/arch-x64.md). + +- **Standard Library enhancements** + + - Standard library support for coroutines. In this example from [P2502R2](https://wg21.link/p2502r2), the `fib` function is a coroutine. When the `co_yield` statement is executed, `fib` is suspended and the value is returned to the caller. You can resume the `fib` coroutine later to produce more values without requiring any manual state handling: + + ```cpp + std::generator fib() + { + auto a = 0, b = 1; + + while (true) + { + co_yield std::exchange(a, std::exchange(b, a + b)); + } + } + + int answer_to_the_universe() + { + auto rng = fib() | std::views::drop(6) | std::views::take(3); + return std::ranges::fold_left(std::move(rng), 0, std::plus{}); + } + ``` + + - Moved `system_clock`, `high_resolution_clock`, and `chrono_literals` from a commonly included internal header to ``. If you see compiler errors that types like `system_clock` or user-defined literals like `1729ms` aren't recognized, include ``. + - Improved the vectorized implementations of `bitset` constructors from strings, `basic_string::find_last_of()`, `remove()`, `ranges::remove`, and the `minmax_element()` and `minmax()` algorithm families. + - Added vectorized implementations of: + - `find_end()` and `ranges::find_end` for 1-byte and 2-byte elements. + - `basic_string::find()` and `basic_string::rfind()` for a substring. + - `basic_string::rfind()` for a single character. + - Merged C++23 Defect Reports: + - [P3107R5](https://wg21.link/P3107R5) Permit an efficient implementation of ``. + - [P3235R3](https://wg21.link/P3235R3) `std::print` More types faster with less memory. + +- **GitHub Copilot** + + - GitHub Copilot Free is now available.

By using C++ AMP, you can code multi-dimensional data algorithms so that execution can be accelerated by using parallelism on heterogeneous hardware. The C++ AMP programming model includes multidimensional arrays, indexing, memory transfer, tiling, and a mathematical function library. You can use C++ AMP language extensions to control how data is moved from the CPU to the GPU and back, so that you can improve performance. - -## System Requirements - -- Windows 7 or later - -- Windows Server 2008 R2 through Visual Studio 2019. - -- DirectX 11 Feature Level 11.0 or later hardware - -- For debugging on the software emulator, Windows 8 or Windows Server 2012 is required. For debugging on the hardware, you must install the drivers for your graphics card. For more information, see [Debugging GPU Code](/visualstudio/debugger/debugging-gpu-code). - -- Note: AMP is currently not supported on ARM64. - -## Introduction - -The following two examples illustrate the primary components of C++ AMP. Assume that you want to add the corresponding elements of two one-dimensional arrays. For example, you might want to add `{1, 2, 3, 4, 5}` and `{6, 7, 8, 9, 10}` to obtain `{7, 9, 11, 13, 15}`. Without using C++ AMP, you might write the following code to add the numbers and display the results. - -```cpp -#include - -void StandardMethod() { - - int aCPP[] = {1, 2, 3, 4, 5}; - int bCPP[] = {6, 7, 8, 9, 10}; - int sumCPP[5]; - - for (int idx = 0; idx < 5; idx++) - { - sumCPP[idx] = aCPP[idx] + bCPP[idx]; - } - - for (int idx = 0; idx < 5; idx++) - { - std::cout << sumCPP[idx] << "\n"; - } -} -``` - -The important parts of the code are as follows: - -- Data: The data consists of three arrays. All have the same rank (one) and length (five). - -- Iteration: The first **`for`** loop provides a mechanism for iterating through the elements in the arrays. The code that you want to execute to compute the sums is contained in the first **`for`** block. - -- Index: The `idx` variable accesses the individual elements of the arrays. - -Using C++ AMP, you might write the following code instead. - -```cpp -#include -#include -using namespace concurrency; - -const int size = 5; - -void CppAmpMethod() { - int aCPP[] = {1, 2, 3, 4, 5}; - int bCPP[] = {6, 7, 8, 9, 10}; - int sumCPP[size]; - - // Create C++ AMP objects. - array_view a(size, aCPP); - array_view b(size, bCPP); - array_view sum(size, sumCPP); - sum.discard_data(); - - parallel_for_each( - // Define the compute domain, which is the set of threads that are created. - sum.extent, - // Define the code to run on each thread on the accelerator. - [=](index<1> idx) restrict(amp) { - sum[idx] = a[idx] + b[idx]; - } - ); - - // Print the results. The expected output is "7, 9, 11, 13, 15". - for (int i = 0; i < size; i++) { - std::cout << sum[i] << "\n"; - } -} -``` - -The same basic elements are present, but C++ AMP constructs are used: - -- Data: You use C++ arrays to construct three C++ AMP [array_view](../../parallel/amp/reference/array-view-class.md) objects. You supply four values to construct an `array_view` object: the data values, the rank, the element type, and the length of the `array_view` object in each dimension. The rank and type are passed as type parameters. The data and length are passed as constructor parameters. In this example, the C++ array that is passed to the constructor is one-dimensional. The rank and length are used to construct the rectangular shape of the data in the `array_view` object, and the data values are used to fill the array. The runtime library also includes the [array Class](../../parallel/amp/reference/array-class.md), which has an interface that resembles the `array_view` class and is discussed later in this article. - -- Iteration: The [parallel_for_each Function (C++ AMP)](reference/concurrency-namespace-functions-amp.md#parallel_for_each) provides a mechanism for iterating through the data elements, or *compute domain*. In this example, the compute domain is specified by `sum.extent`. The code that you want to execute is contained in a lambda expression, or *kernel function*. The `restrict(amp)` indicates that only the subset of the C++ language that C++ AMP can accelerate is used. - -- Index: The [index Class](../../parallel/amp/reference/index-class.md) variable, `idx`, is declared with a rank of one to match the rank of the `array_view` object. By using the index, you can access the individual elements of the `array_view` objects. - -## Shaping and Indexing Data: index and extent - -You must define the data values and declare the shape of the data before you can run the kernel code. All data is defined to be an array (rectangular), and you can define the array to have any rank (number of dimensions). The data can be any size in any of the dimensions. - -### index Class - -The [index Class](../../parallel/amp/reference/index-class.md) specifies a location in the `array` or `array_view` object by encapsulating the offset from the origin in each dimension into one object. When you access a location in the array, you pass an `index` object to the indexing operator, `[]`, instead of a list of integer indexes. You can access the elements in each dimension by using the [array::operator() Operator](reference/array-class.md#operator_call) or the [array_view::operator() Operator](reference/array-view-class.md#operator_call). - -The following example creates a one-dimensional index that specifies the third element in a one-dimensional `array_view` object. The index is used to print the third element in the `array_view` object. The output is 3. - -```cpp -int aCPP[] = {1, 2, 3, 4, 5}; -array_view a(5, aCPP); - -index<1> idx(2); - -std::cout << a[idx] << "\n"; -// Output: 3 -``` - -The following example creates a two-dimensional index that specifies the element where the row = 1 and the column = 2 in a two-dimensional `array_view` object. The first parameter in the `index` constructor is the row component, and the second parameter is the column component. The output is 6. - -```cpp -int aCPP[] = {1, 2, 3, 4, 5, 6}; -array_view a(2, 3, aCPP); - -index<2> idx(1, 2); - -std::cout < a(2, 3, 4, aCPP); - -// Specifies the element at 3, 1, 0. -index<3> idx(0, 1, 3); - -std::cout << a[idx] << "\n"; -// Output: 8 -``` - -### extent Class - -The [extent Class](../../parallel/amp/reference/extent-class.md) specifies the length of the data in each dimension of the `array` or `array_view` object. You can create an extent and use it to create an `array` or `array_view` object. You can also retrieve the extent of an existing `array` or `array_view` object. The following example prints the length of the extent in each dimension of an `array_view` object. - -```cpp -int aCPP[] = { - 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, - 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}; -// There are 3 rows and 4 columns, and the depth is two. -array_view a(2, 3, 4, aCPP); - -std::cout << "The number of columns is " << a.extent[2] << "\n"; -std::cout << "The number of rows is " << a.extent[1] << "\n"; -std::cout << "The depth is " << a.extent[0] << "\n"; -std::cout << "Length in most significant dimension is " << a.extent[0] << "\n"; -``` - -The following example creates an `array_view` object that has the same dimensions as the object in the previous example, but this example uses an `extent` object instead of using explicit parameters in the `array_view` constructor. - -```cpp -int aCPP[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24}; -extent<3> e(2, 3, 4); - -array_view a(e, aCPP); - -std::cout << "The number of columns is " << a.extent[2] << "\n"; -std::cout << "The number of rows is " << a.extent[1] << "\n"; -std::cout << "The depth is " << a.extent[0] << "\n"; -``` - -## Moving Data to the Accelerator: array and array_view - -Two data containers used to move data to the accelerator are defined in the runtime library. They are the [array Class](../../parallel/amp/reference/array-class.md) and the [array_view Class](../../parallel/amp/reference/array-view-class.md). The `array` class is a container class that creates a deep copy of the data when the object is constructed. The `array_view` class is a wrapper class that copies the data when the kernel function accesses the data. When the data is needed on the source device the data is copied back. - -### array Class - -When an `array` object is constructed, a deep copy of the data is created on the accelerator if you use a constructor that includes a pointer to the data set. The kernel function modifies the copy on the accelerator. When the execution of the kernel function is finished, you must copy the data back to the source data structure. The following example multiplies each element in a vector by 10. After the kernel function is finished, the `vector conversion operator` is used to copy the data back into the vector object. - -```cpp -std::vector data(5); - -for (int count = 0; count <5; count++) -{ - data[count] = count; -} - -array a(5, data.begin(), data.end()); - -parallel_for_each( - a.extent, - [=, &a](index<1> idx) restrict(amp) { - a[idx] = a[idx]* 10; - }); - -data = a; -for (int i = 0; i < 5; i++) -{ - std::cout << data[i] << "\n"; -} -``` - -### array_view Class - -The `array_view` has nearly the same members as the `array` class, but the underlying behavior is not the same. Data passed to the `array_view` constructor is not replicated on the GPU as it is with an `array` constructor. Instead, the data is copied to the accelerator when the kernel function is executed. Therefore, if you create two `array_view` objects that use the same data, both `array_view` objects refer to the same memory space. When you do this, you have to synchronize any multithreaded access. The main advantage of using the `array_view` class is that data is moved only if it is necessary. - -### Comparison of array and array_view - -The following table summarizes the similarities and differences between the `array` and `array_view` classes. - -|Description|array class|array_view class| -|-----------------|-----------------|-----------------------| -|When rank is determined|At compile time.|At compile time.| -|When extent is determined|At run time.|At run time.| -|Shape|Rectangular.|Rectangular.| -|Data storage|Is a data container.|Is a data wrapper.| -|Copy|Explicit and deep copy at definition.|Implicit copy when it is accessed by the kernel function.| -|Data retrieval|By copying the array data back to an object on the CPU thread.|By direct access of the `array_view` object or by calling the [array_view::synchronize Method](reference/array-view-class.md#synchronize) to continue accessing the data on the original container.| - -### Shared memory with array and array_view - -Shared memory is memory that can be accessed by both the CPU and the accelerator. The use of shared memory eliminates or significantly reduces the overhead of copying data between the CPU and the accelerator. Although the memory is shared, it cannot be accessed concurrently by both the CPU and the accelerator, and doing so causes undefined behavior. - -`array` objects can be used to specify fine-grained control over the use of shared memory if the associated accelerator supports it. Whether an accelerator supports shared memory is determined by the accelerator's [supports_cpu_shared_memory](reference/accelerator-class.md#supports_cpu_shared_memory) property, which returns **`true`** when shared memory is supported. If shared memory is supported, the default [access_type Enumeration](reference/concurrency-namespace-enums-amp.md#access_type) for memory allocations on the accelerator is determined by the `default_cpu_access_type` property. By default, `array` and `array_view` objects take on the same `access_type` as the primary associated `accelerator`. - -By setting the [array::cpu_access_type Data Member](reference/array-class.md#cpu_access_type) property of an `array` explicitly, you can exercise fine-grained control over how shared memory is used, so that you can optimize the app for the hardware's performance characteristics, based on the memory access patterns of its computation kernels. An `array_view` reflects the same `cpu_access_type` as the `array` that it's associated with; or, if the array_view is constructed without a data source, its `access_type` reflects the environment that first causes it to allocate storage. That is, if it's first accessed by the host (CPU), then it behaves as if it were created over a CPU data source and shares the `access_type` of the `accelerator_view` associated by capture; however, if it's first accessed by an `accelerator_view`, then it behaves as if it were created over an `array` created on that `accelerator_view` and shares the `array`'s `access_type`. - -The following code example shows how to determine whether the default accelerator supports shared memory, and then creates several arrays that have different cpu_access_type configurations. - -```cpp -#include -#include - -using namespace Concurrency; - -int main() -{ - accelerator acc = accelerator(accelerator::default_accelerator); - - // Early out if the default accelerator doesn't support shared memory. - if (!acc.supports_cpu_shared_memory) - { - std::cout << "The default accelerator does not support shared memory" << std::endl; - return 1; - } - - // Override the default CPU access type. - acc.default_cpu_access_type = access_type_read_write - - // Create an accelerator_view from the default accelerator. The - // accelerator_view inherits its default_cpu_access_type from acc. - accelerator_view acc_v = acc.default_view; - - // Create an extent object to size the arrays. - extent<1> ex(10); - - // Input array that can be written on the CPU. - array arr_w(ex, acc_v, access_type_write); - - // Output array that can be read on the CPU. - array arr_r(ex, acc_v, access_type_read); - - // Read-write array that can be both written to and read from on the CPU. - array arr_rw(ex, acc_v, access_type_read_write); -} -``` - -## Executing Code over Data: parallel_for_each - -The [parallel_for_each](reference/concurrency-namespace-functions-amp.md#parallel_for_each) function defines the code that you want to run on the accelerator against the data in the `array` or `array_view` object. Consider the following code from the introduction of this topic. - -```cpp -#include -#include -using namespace concurrency; - -void AddArrays() { - int aCPP[] = {1, 2, 3, 4, 5}; - int bCPP[] = {6, 7, 8, 9, 10}; - int sumCPP[5] = {0, 0, 0, 0, 0}; - - array_view a(5, aCPP); - array_view b(5, bCPP); - array_view sum(5, sumCPP); - - parallel_for_each( - sum.extent, - [=](index<1> idx) restrict(amp) - { - sum[idx] = a[idx] + b[idx]; - } - ); - - for (int i = 0; i < 5; i++) { - std::cout << sum[i] << "\n"; - } -} -``` - -The `parallel_for_each` method takes two arguments, a compute domain and a lambda expression. - -The *compute domain* is an `extent` object or a `tiled_extent` object that defines the set of threads to create for parallel execution. One thread is generated for each element in the compute domain. In this case, the `extent` object is one-dimensional and has five elements. Therefore, five threads are started. - -The *lambda expression* defines the code to run on each thread. The capture clause, `[=]`, specifies that the body of the lambda expression accesses all captured variables by value, which in this case are `a`, `b`, and `sum`. In this example, the parameter list creates a one-dimensional `index` variable named `idx`. The value of the `idx[0]` is 0 in the first thread and increases by one in each subsequent thread. The `restrict(amp)` indicates that only the subset of the C++ language that C++ AMP can accelerate is used. The limitations on functions that have the restrict modifier are described in [restrict (C++ AMP)](../../cpp/restrict-cpp-amp.md). For more information, see, [Lambda Expression Syntax](../../cpp/lambda-expression-syntax.md). - -The lambda expression can include the code to execute or it can call a separate kernel function. The kernel function must include the `restrict(amp)` modifier. The following example is equivalent to the previous example, but it calls a separate kernel function. - -```cpp -#include -#include -using namespace concurrency; - -void AddElements( - index<1> idx, - array_view sum, - array_view a, - array_view b) restrict(amp) { - sum[idx] = a[idx] + b[idx]; -} - -void AddArraysWithFunction() { - - int aCPP[] = {1, 2, 3, 4, 5}; - int bCPP[] = {6, 7, 8, 9, 10}; - int sumCPP[5] = {0, 0, 0, 0, 0}; - - array_view a(5, aCPP); - array_view b(5, bCPP); - array_view sum(5, sumCPP); - - parallel_for_each( - sum.extent, - [=](index<1> idx) restrict(amp) { - AddElements(idx, sum, a, b); - } - ); - - for (int i = 0; i < 5; i++) { - std::cout << sum[i] << "\n"; - } -} -``` - -## Accelerating Code: Tiles and Barriers - -You can gain additional acceleration by using tiling. Tiling divides the threads into equal rectangular subsets or *tiles*. You determine the appropriate tile size based on your data set and the algorithm that you are coding. For each thread, you have access to the *global* location of a data element relative to the whole `array` or `array_view` and access to the *local* location relative to the tile. Using the local index value simplifies your code because you don't have to write the code to translate index values from global to local. To use tiling, call the [extent::tile Method](reference/extent-class.md#tile) on the compute domain in the `parallel_for_each` method, and use a [tiled_index](../../parallel/amp/reference/tiled-index-class.md) object in the lambda expression. - -In typical applications, the elements in a tile are related in some way, and the code has to access and keep track of values across the tile. Use the [tile_static Keyword](../../cpp/tile-static-keyword.md) keyword and the [tile_barrier::wait Method](reference/tile-barrier-class.md#wait) to accomplish this. A variable that has the **tile_static** keyword has a scope across an entire tile, and an instance of the variable is created for each tile. You must handle synchronization of tile-thread access to the variable. The [tile_barrier::wait Method](reference/tile-barrier-class.md#wait) stops execution of the current thread until all the threads in the tile have reached the call to `tile_barrier::wait`. So you can accumulate values across the tile by using **tile_static** variables. Then you can finish any computations that require access to all the values. - -The following diagram represents a two-dimensional array of sampling data that is arranged in tiles. - -![Index values in a tiled extent.](../../parallel/amp/media/camptiledgridexample.png "Index values in a tiled extent") - -The following code example uses the sampling data from the previous diagram. The code replaces each value in the tile by the average of the values in the tile. - -```cpp -// Sample data: -int sampledata[] = { - 2, 2, 9, 7, 1, 4, - 4, 4, 8, 8, 3, 4, - 1, 5, 1, 2, 5, 2, - 6, 8, 3, 2, 7, 2}; - -// The tiles: -// 2 2 9 7 1 4 -// 4 4 8 8 3 4 -// -// 1 5 1 2 5 2 -// 6 8 3 2 7 2 - -// Averages: -int averagedata[] = { - 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, -}; - -array_view sample(4, 6, sampledata); - -array_view average(4, 6, averagedata); - -parallel_for_each( - // Create threads for sample.extent and divide the extent into 2 x 2 tiles. - sample.extent.tile<2,2>(), - [=](tiled_index<2,2> idx) restrict(amp) { - // Create a 2 x 2 array to hold the values in this tile. - tile_static int nums[2][2]; - - // Copy the values for the tile into the 2 x 2 array. - nums[idx.local[1]][idx.local[0]] = sample[idx.global]; - - // When all the threads have executed and the 2 x 2 array is complete, find the average. - idx.barrier.wait(); - int sum = nums[0][0] + nums[0][1] + nums[1][0] + nums[1][1]; - - // Copy the average into the array_view. - average[idx.global] = sum / 4; - }); - -for (int i = 0; i <4; i++) { - for (int j = 0; j <6; j++) { - std::cout << average(i,j) << " "; - } - std::cout << "\n"; -} - -// Output: -// 3 3 8 8 3 3 -// 3 3 8 8 3 3 -// 5 5 2 2 4 4 -// 5 5 2 2 4 4 -``` - -## Math Libraries - -C++ AMP includes two math libraries. The double-precision library in the [Concurrency::precise_math Namespace](../../parallel/amp/reference/concurrency-precise-math-namespace.md) provides support for double-precision functions. It also provides support for single-precision functions, although double-precision support on the hardware is still required. It conforms to the [C99 Specification (ISO/IEC 9899)](https://go.microsoft.com/fwlink/p/?linkid=225887). The accelerator must support full double precision. You can determine whether it does by checking the value of the [accelerator::supports_double_precision Data Member](reference/accelerator-class.md#supports_double_precision). The fast math library, in the [Concurrency::fast_math Namespace](../../parallel/amp/reference/concurrency-fast-math-namespace.md), contains another set of math functions. These functions, which support only **`float`** operands, execute more quickly but aren't as precise as those in the double-precision math library. The functions are contained in the \ header file and all are declared with `restrict(amp)`. The functions in the \ header file are imported into both the `fast_math` and `precise_math` namespaces. The **`restrict`** keyword is used to distinguish the \ version and the C++ AMP version. The following code calculates the base-10 logarithm, using the fast method, of each value that is in the compute domain. - -```cpp -#include -#include -#include -using namespace concurrency; - -void MathExample() { - - double numbers[] = { 1.0, 10.0, 60.0, 100.0, 600.0, 1000.0 }; - array_view logs(6, numbers); - - parallel_for_each( - logs.extent, - [=] (index<1> idx) restrict(amp) { - logs[idx] = concurrency::fast_math::log10(numbers[idx]); - } - ); - - for (int i = 0; i < 6; i++) { - std::cout << logs[i] << "\n"; - } -} -``` - -## Graphics Library - -C++ AMP includes a graphics library that is designed for accelerated graphics programming. This library is used only on devices that support native graphics functionality. The methods are in the [Concurrency::graphics Namespace](../../parallel/amp/reference/concurrency-graphics-namespace.md) and are contained in the \ header file. The key components of the graphics library are: - -- [texture Class](../../parallel/amp/reference/texture-class.md): You can use the texture class to create textures from memory or from a file. Textures resemble arrays because they contain data, and they resemble containers in the C++ Standard Library with respect to assignment and copy construction. For more information, see [C++ Standard Library Containers](../../standard-library/stl-containers.md). The template parameters for the `texture` class are the element type and the rank. The rank can be 1, 2, or 3. The element type can be one of the short vector types that are described later in this article. - -- [writeonly_texture_view Class](../../parallel/amp/reference/writeonly-texture-view-class.md): Provides write-only access to any texture. - -- Short Vector Library: Defines a set of short vector types of length 2, 3, and 4 that are based on **`int`**, `uint`, **`float`**, **`double`**, [norm](../../parallel/amp/reference/norm-class.md), or [unorm](../../parallel/amp/reference/unorm-class.md). - -## Universal Windows Platform (UWP) Apps - -Like other C++ libraries, you can use C++ AMP in your UWP apps.

Some common scenarios are: - -- You can use the [`texture`](../../parallel/amp/reference/texture-class.md) class as a data container for computation and exploit the *spatial locality* of the texture cache and layouts of GPU hardware. Spatial locality is the property of data elements being physically close to each other. - -- The runtime provides efficient interoperability with non-compute shaders. Pixel, vertex, tessellation, and hull shaders frequently consume or produce textures that you can use in your C++ AMP computations. - -- The graphics APIs in C++ AMP provide alternative ways to access sub-word packed buffers. Textures that have formats that represent *texels* (texture elements) that are composed of 8-bit or 16-bit scalars allow access to such packed data storage. - -> [!NOTE] -> C++ AMP headers are deprecated starting with Visual Studio 2022 version 17.0. -> Including any AMP headers will generate build errors. Define `_SILENCE_AMP_DEPRECATION_WARNINGS` before including any AMP headers to silence the warnings. - -## The norm and unorm Types - -The `norm` and `unorm` types are scalar types that limit the range of **`float`** values; this is known as *clamping*. These types can be explicitly constructed from other scalar types. In casting, the value is first cast to **`float`** and then clamped to the respective region that's allowed by `norm [-1.0, 1.0]` or `unorm [0.0, 1.0]`. Casting from +/- infinity returns +/-1. Casting from NaN is undefined. A `norm` can be implicitly constructed from a `unorm` and there is no loss of data. The implicit conversion operator to **`float`** is defined on these types. Binary operators are defined between these types and other built-in scalar types such as **`float`** and **`int`**: `+`, `-`, `*`, `/`, `==`, `!=`, `>`, `<`, `>=`, `<=`. The compound assignment operators are also supported: `+=`, `-=`, `*=`, `/=`. The unary negation operator (`-`) is defined for `norm` types. - -## Short Vector Library - -The Short Vector Library provides some of the functionality of the [Vector Type](/windows/win32/direct3dhlsl/dx-graphics-hlsl-vector) that's defined in HLSL and is typically used to define texels. A short vector is a data structure that holds one to four values of the same type. The supported types are **`double`**, **`float`**, **`int`**, `norm`, `uint`, and `unorm`. The type names are shown in the following table. For each type, there is also a corresponding **`typedef`** that doesn't have an underscore in the name. The types that have the underscores are in the [Concurrency::graphics Namespace](../../parallel/amp/reference/concurrency-graphics-namespace.md). The types that don't have the underscores are in the [Concurrency::graphics::direct3d Namespace](../../parallel/amp/reference/concurrency-graphics-direct3d-namespace.md) so that they are clearly separated from the similarly-named fundamental types such as **`__int8`** and **`__int16`**. - -|Type|Length 2|Length 3|Length 4| -|-|--------------|--------------|--------------| -|double|double_2

Also, one of these must be true: - -- The scalar's type must be the same as the short vector's element type. - -- The scalar's type can be implicitly converted to the vector's element type by using only one user-defined conversion. - -The operation is carried component-wise between each component of the short vector and the scalar. Here are the valid operators: - -|Operator type|Valid types| -|-------------------|-----------------| -|Binary operators|Valid on all types: `+`, `-`, `*`, `/`,

Valid on integer types: `%`, `^`, `|`, `&`, `<<`, `>>`

The two vectors must have the same size, and the result is a vector of the same size.| -|Relational operators|Valid on all types: `==` and `!=`| -|Compound assignment operator|Valid on all types: `+=`, `-=`, `*=`, `/=`

Valid on integer types: `%=`, `^=`, `|=`, `&=`, `<<=`, `>>=`| -|Increment and decrement operators|Valid on all types: `++`, `--`

Both prefix and postfix are valid.| -|Bitwise NOT operator (`~`)|Valid on integer types.| -|Unary `-` operator|Valid on all types except `unorm` and `uint`.| - -### Swizzling Expressions - -The Short Vector Library supports the `vector_type.identifier` accessor construct to access the components of a short vector. The `identifier`, which is known as a *swizzling expression*, specifies the components of the vector. The expression can be an l-value or an r-value. Individual characters in the identifier may be: x, y, z, and w; or r, g, b, and a. "x" and "r" mean the zero-th component, "y" and "g" mean the first component, and so on. (Notice that "x" and "r" cannot be used in the same identifier.) Therefore, "rgba" and "xyzw" return the same result. Single-component accessors such as "x" and "y" are scalar value types. Multi-component accessors are short vector types. For example, if you construct an `int_4` vector that's named `fourInts` and has the values 2, 4, 6, and 8, then `fourInts.y` returns the integer 4 and `fourInts.rg` returns an `int_2` object that has the values 2 and 4. - -## Texture Classes - -Many GPUs have hardware and caches that are optimized to fetch pixels and texels and to render images and textures. The [`texture`](../../parallel/amp/reference/texture-class.md) class, which is a container class for texel objects, exposes the texture functionality of these GPUs. A texel can be: - -- An **`int`**, `uint`, **`float`**, **`double`**, `norm`, or `unorm` scalar. - -- A short vector that has two or four components. The only exception is `double_4`, which is not allowed. - -The `texture` object can have a rank of 1, 2, or 3. The `texture` object can be captured only by reference in the lambda of a call to `parallel_for_each`. The texture is stored on the GPU as Direct3D texture objects. For more information about textures and texels in Direct3D, see [Introduction to Textures in Direct3D 11](/windows/win32/direct3d11/overviews-direct3d-11-resources-textures-intro). - -The texel type you use might be one of the many texture formats that are used in graphics programming. For example, an RGBA format could use 32 bits, with 8 bits each for the R, G, B, and A scalar elements. The texture hardware of a graphics card can access the individual elements based on the format. For example, if you are using the RGBA format, the texture hardware can extract each 8-bit element into a 32-bit form. In C++ AMP, you can set the bits per scalar element of your texel so that you can automatically access the individual scalar elements in the code without using bit-shifting. - -### Instantiating Texture Objects - -You can declare a texture object without initialization. The following code example declares several texture objects. - -```cpp -#include -#include -using namespace concurrency; -using namespace concurrency::graphics; - -void declareTextures() { - // Create a 16-texel texture of int. - texture intTexture1(16); - texture intTexture2(extent<1>(16)); - - // Create a 16 x 32 texture of float_2. - texture floatTexture1(16, 32); - texture floatTexture2(extent<2>(16, 32)); - - // Create a 2 x 4 x 8 texture of uint_4. - texture uintTexture1(2, 4, 8); - texture uintTexture2(extent<3>(2, 4, 8)); -} -``` - -You can also use a constructor to declare and initialize a `texture` object. The following code example instantiates a `texture` object from a vector of `float_4` objects. The bits per scalar element is set to the default. You cannot use this constructor with `norm`, `unorm`, or the short vectors of `norm` and `unorm`, because they do not have a default bits per scalar element. - -```cpp -#include -#include -#include -using namespace concurrency; -using namespace concurrency::graphics; - -void initializeTexture() { - std::vector texels; - for (int i = 0; i < 768 * 1024; i++) { - int_4 i4(i, i, i, i); - texels.push_back(i4); - } - - texture aTexture(768, 1024, texels.begin(), texels.end()); -} -``` - -You can also declare and initialize a `texture` object by using a constructor overload that takes a pointer to the source data, the size of source data in bytes, and the bits per scalar element. - -```cpp -void createTextureWithBPC() { // Create the source data. - float source[1024* 2]; - for (int i = 0; i <1024* 2; i++) { - source[i] = (float)i; - } - // Initialize the texture by using the size of source in bytes // and bits per scalar element. - texture floatTexture(1024, source, (unsigned int)sizeof(source), 32U); -} -``` - -The textures in these examples are created on the default view of the default accelerator. You can use other overloads of the constructor if you want to specify an `accelerator_view` object. You cannot create a texture object on a CPU accelerator. - -There are limits on the size of each dimension of the `texture` object, as shown in the following table. A run-time error is generated if you exceed the limits. - -|Texture|Size limitation per dimension| -|-------------|---------------------| -|texture\|16384| -|texture\|16384| -|texture\|2048| - -### Reading from Texture Objects - -You can read from a `texture` object by using [texture::operator\[\]](reference/texture-class.md#operator_at), [texture::operator() Operator](reference/texture-class.md#operator_call), or [texture::get Method](reference/texture-class.md#get). The two operators return a value, not a reference. Therefore, you cannot write to a `texture` object by using `texture::operator\[\]`. - -```cpp -void readTexture() { - std::vector src; - for (int i = 0; i <16 *32; i++) { - int_2 i2(i, i); - - src.push_back(i2); - } - - std::vector dst(16* 32); - - array_view arr(16, 32, dst); - - arr.discard_data(); - - const texture tex9(16, 32, src.begin(), src.end()); - - parallel_for_each(tex9.extent, [=, &tex9] (index<2> idx) restrict(amp) { // Use the subscript operator. - arr[idx].x += tex9[idx].x; // Use the function () operator. - arr[idx].x += tex9(idx).x; // Use the get method. - arr[idx].y += tex9.get(idx).y; // Use the function () operator. - arr[idx].y += tex9(idx[0], idx[1]).y; - }); - - arr.synchronize(); -} -``` - -The following code example demonstrates how to store texture channels in a short vector, and then access the individual scalar elements as properties of the short vector. - -```cpp -void UseBitsPerScalarElement() { // Create the image data. // Each unsigned int (32-bit) represents four 8-bit scalar elements(r,g,b,a values). - const int image_height = 16; - const int image_width = 16; - std::vector image(image_height* image_width); - - extent<2> image_extent(image_height, image_width); - - // By using uint_4 and 8 bits per channel, each 8-bit channel in the data source is // stored in one 32-bit component of a uint_4. - texture image_texture(image_extent, image.data(), image_extent.size()* 4U, 8U); - - // Use can access the RGBA values of the source data by using swizzling expressions of the uint_4. - parallel_for_each(image_extent, - [&image_texture](index<2> idx) restrict(amp) - { // 4 bytes are automatically extracted when reading. - uint_4 color = image_texture[idx]; - unsigned int r = color.r; - unsigned int g = color.g; - unsigned int b = color.b; - unsigned int a = color.a; - }); -} -``` - -The following table lists the valid bits per channel for each sort vector type. - -|Texture data type|Valid bits per scalar element| -|-----------------------|-----------------------------------| -|int, int_2, int_4

unorm, unorm_2, unorm, 4|8, 16| - -### Writing to Texture Objects - -Use the [texture::set](reference/texture-class.md#set) method to write to `texture` objects. A texture object can be readonly or read/write. For a texture object to be readable and writeable, the following conditions must be true: - -- T has only one scalar component. (Short vectors are not allowed.) - -- T is not **`double`**, `norm`, or `unorm`. - -- The `texture::bits_per_scalar_element` property is 32. - -If all three are not true, then the `texture` object is readonly. The first two conditions are checked during compilation. A compilation error is generated if you have code that tries to write to a `readonly` texture object. The condition for `texture::bits_per_scalar_element` is detected at run time, and the runtime generates the [unsupported_feature](../../parallel/amp/reference/unsupported-feature-class.md) exception if you try to write to a readonly `texture` object. - -The following code example writes values to a texture object. - -```cpp -void writeTexture() { - texture tex1(16); - - parallel_for_each(tex1.extent, [&tex1] (index<1> idx) restrict(amp) { - tex1.set(idx, 0); - }); -} -``` - -### Copying Texture Objects - -You can copy between texture objects by using the [copy](reference/concurrency-namespace-functions-amp.md#copy) function or the [copy_async](reference/concurrency-namespace-functions-amp.md#copy_async) function, as shown in the following code example. - -```cpp -void copyHostArrayToTexture() { // Copy from source array to texture object by using the copy function. - float floatSource[1024* 2]; - for (int i = 0; i <1024* 2; i++) { - floatSource[i] = (float)i; - } - texture floatTexture(1024); - - copy(floatSource, (unsigned int)sizeof(floatSource), floatTexture); - - // Copy from source array to texture object by using the copy function. - char charSource[16* 16]; - for (int i = 0; i <16* 16; i++) { - charSource[i] = (char)i; - } - texture charTexture(16, 16, 8U); - - copy(charSource, (unsigned int)sizeof(charSource), charTexture); - // Copy from texture object to source array by using the copy function. - copy(charTexture, charSource, (unsigned int)sizeof(charSource)); -} -``` - -You can also copy from one texture to another by using the [texture::copy_to](reference/texture-class.md#copy_to) method. The two textures can be on different accelerator_views. When you copy to a `writeonly_texture_view` object, the data is copied to the underlying `texture` object. The bits per scalar element and the extent must be the same on the source and destination `texture` objects. If those requirements are not met, the runtime throws an exception. - -## Texture View Classes - -C++ AMP introduces the [texture_view Class](../../parallel/amp/reference/texture-view-class.md) in Visual Studio 2013. Texture views support the same texel types and ranks as the [texture Class](../../parallel/amp/reference/texture-class.md), but unlike textures, they provide access to additional hardware features such as texture sampling and mipmaps. Texture views support read-only, write-only, and read-write access to the underlying texture data. - -- Read-only access is provided by the `texture_view` template specialization, which supports elements that have 1, 2, or 4 components, texture sampling, and dynamic access to a range of mipmap levels that are determined when the view is instantiated. - -- Write-only access is provided by the non-specialized template class `texture_view`, which supports elements that have either 2 or 4 components and can access one mipmap level that's determined when the view is instantiated. It does not support sampling. - -- Read-write access is provided by the non-specialized template class `texture_view`, which, like textures, supports elements that have only one component; the view can access one mipmap level that's determined when it is instantiated. It does not support sampling. - -Texture views are analogous to array views, but do not provide the automatic data management and movement functionality that the [array_view Class](../../parallel/amp/reference/array-view-class.md) provides over the [array class](../../parallel/amp/reference/array-class.md). A `texture_view` can only be accessed on the accelerator view where the underlying texture data resides. - -### writeonly_texture_view Deprecated - -For Visual Studio 2013, C++ AMP introduces better support for hardware texture features such as sampling and mipmaps, which could not be supported by the [writeonly_texture_view Class](../../parallel/amp/reference/writeonly-texture-view-class.md). The newly introduced `texture_view` class supports a superset of the functionality in `writeonly_texture_view`; as a result, `writeonly_texture_view` is deprecated. - -We recommend—at least for new code—that you use `texture_view` to access functionality that was formerly provided by `writeonly_texture_view`. Compare the following two code examples that write to a texture object that has two components (int_2). Notice that in both cases, the view, `wo_tv4`, must be captured by value in the lambda expression. Here is the example that uses the new `texture_view` class: - -```cpp -void write2ComponentTexture() { - texture tex4(16); - - texture_view wo_tv4(tex4); - - parallel_for_each(extent<1>(16), [=] (index<1> idx) restrict(amp) { - wo_tv4.set(idx, int_2(1, 1)); - }); -} -``` - -And here is the deprecated `writeonly_texture_view` class: - -```cpp -void write2ComponentTexture() { - texture tex4(16); - - writeonly_texture_view wo_tv4(tex4); - - parallel_for_each(extent<1>(16), [=] (index<1> idx) restrict(amp) { - wo_tv4.set(idx, int_2(1, 1)); - }); -} -``` - -As you can see, the two code examples are nearly identical when all you are doing is writing to the primary mipmap level. If you used `writeonly_texture_view` in existing code and you're not planning to enhance that code, you don't have to change it. However, if you're thinking about bringing that code forward, we suggest that you rewrite it to use `texture_view` because the enhancements in it support new hardware texture features. Read on for more information about these new capabilities. - -For more information about the deprecation of `writeonly_texture_view`, see [Overview of the Texture View Design in C++ AMP](/archive/blogs/nativeconcurrency/overview-of-the-texture-view-design-in-c-amp) on the Parallel Programming in Native Code blog. - -### Instantiating Texture View Objects - -Declaring a `texture_view` is similar to declaring an `array_view` that's associated with an **array**. The following code example declares several `texture` objects and `texture_view` objects that are associated with them. - -```cpp -#include -#include -using namespace concurrency; -using namespace concurrency::graphics; - -void declareTextureViews() -{ - // Create a 16-texel texture of int, with associated texture_views. - texture intTexture(16); - texture_view intTextureViewRO(intTexture); // read-only - texture_view intTextureViewRW(intTexture); // read-write - - // Create a 16 x 32 texture of float_2, with associated texture_views. - texture floatTexture(16, 32); - texture_view floatTextureViewRO(floatTexture); // read-only - texture_view floatTextureViewRO(floatTexture); // write-only - - // Create a 2 x 4 x 8 texture of uint_4, with associated texture_views. - texture uintTexture(2, 4, 8); - texture_view uintTextureViewRO(uintTexture); // read-only - texture_view uintTextureViewWO(uintTexture); // write-only -} -``` - -Notice how a texture view whose element type is non-const and has one component is read-write, but a texture view whose element type is non-const but has more than one componenent are write-only. Texture views of const element types are always read-only, but if the element type is non-const, then the number of components in the element determines whether it is read-write (1 component) or write-only (multiple components). - -The element type of a `texture_view`—its const-ness and also the number of components it has—also plays a role in determining whether the view supports texture sampling, and how mipmap levels can be accessed: - -|Type|Components|Read|Write|Sampling|Mipmap access| -|----------|----------------|----------|-----------|--------------|-------------------| -|texture_view\|1, 2, 4|Yes|No (1)|Yes|Yes, indexable. Range is determined at instantiation.| -|Texture_view\|1

2, 4|Yes

No (2)|Yes

Yes|No (1)

No (1)|Yes, one level. Level is determined at instantiation.

Yes, one level. Level is determined at instantiation.| - -From this table, you can see that read-only texture views fully support the new capabilities in exchange for not being able to write to the view. Writable texture views are limited in that they can only access one mipmap level. Read-write texture views are even more specialized than writable ones, because they add the requirement that the element type of the texture view has only one component. Notice that sampling is not supported for writable texture views because it's a read-oriented operation. - -### Reading from Texture View Objects - -Reading unsampled texture data through a texture view is just like reading it from the texture itself, except that textures are captured by reference, whereas texture views are captured by value. The following two code examples demonstrate; first, by using `texture` only: - -```cpp -void write2ComponentTexture() { - texture text_data(16); - - parallel_for_each(extent<1>(16), [&] (index<1> idx) restrict(amp) { - tex_data.set(idx, int_2(1, 1)); - }); -} -``` - -And here is the same example, except it now uses the `texture_view` class: - -```cpp -void write2ComponentTexture() { - texture tex_data(16); - - texture_view tex_view(tex_data); - - parallel_for_each(extent<1>(16), [=] (index<1> idx) restrict(amp) { - tex_view.set(idx, int_2(1, 1)); - }); -} -``` - -Texture views whose elements are based on floating-point types—for example, float, float_2, or float_4—can also be read by using texture sampling to take advantage of hardware support for various filtering modes and addressing modes. C++ AMP supports the two filtering modes that are most common in compute scenarios—point-filtering (nearest-neighbor) and linear-filtering (weighted average)—and four addressing modes—wrapped, mirrored, clamped, and border. For more information about addressing modes, see [address_mode Enumeration](reference/concurrency-graphics-namespace-enums.md#address_mode). - -In addition to modes that C++ AMP supports directly, you can access other filtering modes and addressing modes of the underlying platform by using the interop APIs to adopt a texture sampler that was created by using the platform APIs directly. For example, Direct3D supports other filtering modes such as anisotropic filtering, and can apply a different addressing mode to each dimension of a texture. You could create a texture sampler whose coordinates are wrapped vertically, mirrored horizontally, and sampled with anisotropic filtering by using the Direct3D APIs, and then leverage the sampler in your C++ AMP code by using the `make_sampler` interop API. For more information see [Texture Sampling in C++ AMP](/archive/blogs/nativeconcurrency/texture-sampling-in-c-amp) on the Parallel Programming in Native Code blog. - -Texture views also support the reading of mipmaps. Read-only texture views (those that have a const element type) offer the most flexibility because a range of mip-levels that is determined at instantiation can be dynamically sampled, and because elements that have 1, 2, or 4 components are supported. Read-write texture views that have elements that have one component also support mipmaps, but only of a level that's determined at instantiation. For more information, see [Texture with Mipmaps](/archive/blogs/nativeconcurrency/texture-with-mipmaps) on the Parallel Programming in Native Code blog. - -### Writing to Texture View Objects - -Use the [texture_view::get Method](reference/texture-view-class.md#get) to write to the underlying `texture` through the `texture_view` object. A texture view can be read-only, read-write, or write-only. For a texture view to be writable it must have an element type that is non-const; for a texture view to be readable and writable, its element type must also have only one component. Otherwise, the texture view is read-only. You can only access one mipmap level of a texture at a time through a texture view, and the level is specified when the view is instantiated. - -This example shows how to write to the second-most detailed mipmap level of a texture that has 4 mipmap levels. The most detailed mipmap level is level 0. - -```cpp -// Create a texture that has 4 mipmap levels : 16x16, 8x8, 4x4, 2x2 -texture tex(extent<2>(16, 16), 16U, 4); - -// Create a writable texture view to the second mipmap level :4x4 -texture_view w_view(tex, 1); - -parallel_for_each(w_view.extent, [=](index<2> idx) restrict(amp) -{ - w_view.set(idx, 123); -}); -``` - -## Interoperability - -The C++ AMP runtime supports interoperability between `texture` and the [ID3D11Texture1D interface](/windows/win32/api/d3d11/nn-d3d11-id3d11texture1d), between `texture` and the [ID3D11Texture2D interface](/windows/win32/api/d3d11/nn-d3d11-id3d11texture2d), and between `texture` and the [ID3D11Texture3D interface](/windows/win32/api/d3d11/nn-d3d11-id3d11texture3d). The [get_texture](reference/concurrency-graphics-direct3d-namespace-functions.md#get_texture) method takes a `texture` object and returns an `IUnknown` interface. The [make_texture](reference/concurrency-graphics-direct3d-namespace-functions.md#make_texture) method takes an `IUnknown` interface and an `accelerator_view` object and returns a `texture` object. - -## See also - -[double_2 Class](../../parallel/amp/reference/double-2-class.md)

When you access the object remotely, views are copied and cached as necessary. Except for the effects of automatic caching, `array_view` objects have a performance profile similar to that of `array` objects. There is a small performance penalty when you access the data through views. - -There are three remote usage scenarios: - -- A view to a system memory pointer is passed by means of a [parallel_for_each](../../../parallel/concrt/reference/concurrency-namespace-functions.md#parallel_for_each) call to an accelerator and accessed on the accelerator. - -- A view to an array located on an accelerator is passed by means of a `parallel_for_each` call to another accelerator and is accessed there. - -- A view to an array located on an accelerator is accessed on the CPU. - -In any one of these scenarios, the referenced views are copied by the runtime to the remote location and, if modified by the calls to the `array_view` object, are copied back to the local location. The runtime might optimize the process of copying changes back, might copy only changed elements, or might copy unchanged portions also. Overlapping `array_view` objects on one data source are not guaranteed to maintain referential integrity in a remote location. - -You must synchronize any multithreaded access to the same data source. - -The runtime makes the following guarantees regarding the caching of data in `array_view` objects: - -- All well-synchronized accesses to an `array` object and an `array_view` object on it in program order obey a serial happens-before relationship. - -- All well-synchronized accesses to overlapping `array_view` objects on the same accelerator on a single `array` object are aliased through the `array` object. They induce a total occurs-before relationship which obeys program order. There is no caching. If the `array_view` objects are executing on different accelerators, the order of access is undefined, creating a race condition. - -When you create an `array_view` object using a pointer in system memory, you must change the view `array_view` object only through the `array_view` pointer. Alternatively, you must call `refresh()` on one of the `array_view` objects that are attached to the system pointer, if the underlying native memory is changed directly, instead of through the `array_view` object. - -Either action notifies the `array_view` object that the underlying native memory is changed and that any copies that are located on an accelerator are outdated. If you follow these guidelines, the pointer-based views are identical to those provided to views of data-parallel arrays. - -## Inheritance Hierarchy - -`_Array_view_shape` - -`_Array_view_base` - -`array_view` - -## Requirements - -**Header:** amp.h - -**Namespace:** Concurrency - -## ~array_view - -Destroys the `array_view` object. - -```cpp -~array_view()restrict(amp,cpu); -``` - -## array_view - -Initializes a new instance of the `array_view` class. - -```cpp -array_view( - array& _Src)restrict(amp,cpu); - -array_view( - const array_view& _Other)restrict(amp,cpu); - -explicit array_view( - const Concurrency::extent<_Rank>& _Extent) restrict(cpu); - -template < - typename _Container -> -array_view( - const Concurrency::extent<_Rank>& _Extent, - _Container& _Src) restrict(cpu); - -array_view( - const Concurrency::extent<_Rank>& _Extent, - value_type* _Src)restrict(amp,cpu); - -explicit array_view( - int _E0) restrict(cpu); - -template < - typename _Container -> -explicit array_view( - _Container& _Src, - typename std::enable_if::type::value, void **>::type = 0) restrict(cpu); - -template < - typename _Container -> -explicit array_view( - int _E0, - _Container& _Src) restrict(cpu); - -explicit array_view( - int _E0, - int _E1) __CPU_ONLY; - -template < - typename _Container -> -explicit array_view( - int _E0, - int _E1, - _Container& _Src) restrict(cpu); - -explicit array_view( - int _E0, - int _E1, - int _E2) __CPU_ONLY; - -template < - typename _Container -> -explicit array_view( - int _E0, - int _E1, - int _E2, - _Container& _Src); - -explicit array_view( - int _E0, - _In_ value_type* _Src)restrict(amp,cpu); - -template < - typename _Arr_type, - int _Size -> -explicit array_view( - _In_ _Arr_type (& _Src) [_Size]) restrict(amp,cpu); - -explicit array_view( - int _E0, - int _E1, - _In_ value_type* _Src)restrict(amp,cpu); - -explicit array_view( - int _E0, - int _E1, - int _E2, - _In_ value_type* _Src)restrict(amp,cpu); - -array_view( - const array& _Src)restrict(amp,cpu); - -array_view( - const array_view& _Src)restrict(amp,cpu); - -array_view( - const array_view& _Src)restrict(amp,cpu); - -template < - typename _Container -> -array_view( - const Concurrency::extent<_Rank>& _Extent, - const _Container& _Src) restrict(cpu); - -template < - typename _Container -> -explicit array_view( - const _Container& _Src, - typename std::enable_if::type::value, void **>::type = 0) restrict(cpu); - -array_view( - const Concurrency::extent<_Rank>& _Extent, - const value_type* _Src)restrict(amp,cpu); - -template < - typename _Arr_type, - int _Size -> -explicit array_view( - const _In_ _Arr_type (& _Src) [_Size]) restrict(amp,cpu); - -template < - typename _Container -> -array_view( - int _E0, - const _Container& _Src); - -template < - typename _Container -> -array_view( - int _E0, - int _E1, - const _Container& _Src); - -template < - typename _Container -> -array_view( - int _E0, - int _E1, - int _E2, - const _Container& _Src); - -array_view( - int _E0, - const value_type* _Src)restrict(amp,cpu); - -array_view( - int _E0, - int _E1, - const value_type* _Src) restrict(amp,cpu); - -array_view( - int _E0, - int _E1, - int _E2, - const value_type* _Src) restrict(amp,cpu); -``` - -### Parameters - -*_Arr_type*

A system might have several devices or emulators that differ by amount of memory, shared memory support, debugging support, or double-precision support. C++ Accelerated Massive Parallelism (C++ AMP) provides APIs that you can use to examine the available accelerators, set one as the default, specify multiple accelerator_views for multiple calls to parallel_for_each, and perform special debugging tasks. - -> [!NOTE] -> C++ AMP headers are deprecated starting with Visual Studio 2022 version 17.0. -> Including any AMP headers will generate build errors. Define `_SILENCE_AMP_DEPRECATION_WARNINGS` before including any AMP headers to silence the warnings. - -## Using the Default Accelerator - -The C++ AMP runtime picks a default accelerator, unless you write code to pick a specific one. The runtime chooses the default accelerator as follows: - -1. If the app is running in debug mode, an accelerator that supports debugging. - -2. Otherwise, the accelerator that's specified by the `CPPAMP_DEFAULT_ACCELERATOR` environment variable, if it's set. - -3. Otherwise, a non-emulated device. - -4. Otherwise, the device that has the greatest amount of available memory. - -5. Otherwise, a device that's not attached to the display. - -Additionally, the runtime specifies an `access_type` of `access_type_auto` for the default accelerator. This means that the default accelerator uses shared memory if it's supported and if its performance characteristics (bandwidth and latency) are known to be the same as dedicated (non-shared) memory. - -You can determine the properties of the default accelerator by constructing the default accelerator and examining its properties. The following code example prints the path, amount of accelerator memory, shared memory support, double-precision support, and limited double-precision support of the default accelerator. - -```cpp -void default_properties() { - accelerator default_acc; - std::wcout << default_acc.device_path << "\n"; - std::wcout << default_acc.dedicated_memory << "\n"; - std::wcout << (accs[i].supports_cpu_shared_memory ? - "CPU shared memory: true" : "CPU shared memory: false") << "\n"; - std::wcout << (accs[i].supports_double_precision ? - "double precision: true" : "double precision: false") << "\n"; - std::wcout << (accs[i].supports_limited_double_precision ? - "limited double precision: true" : "limited double precision: false") << "\n"; -} -``` - -### CPPAMP_DEFAULT_ACCELERATOR Environment Variable - -You can set the CPPAMP_DEFAULT_ACCELERATOR environment variable to specify the `accelerator::device_path` of the default accelerator. The path is hardware-dependent. The following code uses the `accelerator::get_all` function to retrieve a list of the available accelerators and then displays the path and characteristics of each accelerator. - -```cpp -void list_all_accelerators() -{ - std::vector accs = accelerator::get_all(); - - for (int i = 0; i accs = accelerator::get_all(); - accelerator acc_chosen = accs[0]; - - for (int i = 0; i acc_chosen.dedicated_memory) { - acc_chosen = accs[i]; - } - } - - std::wcout << "The accelerator with the most memory is " - << acc_chosen.device_path << "\n" - << acc_chosen.dedicated_memory << ".\n"; -} -``` - -> [!NOTE] -> One of the accelerators that are returned by `accelerator::get_all` is the CPU accelerator. You cannot execute code on the CPU accelerator. To filter out the CPU accelerator, compare the value of the [device_path](reference/accelerator-class.md#device_path) property of the accelerator that's returned by `accelerator::get_all` with the value of the [accelerator::cpu_accelerator](reference/accelerator-class.md#cpu_accelerator). For more information, see the "Special Accelerators" section in this article. - -## Shared Memory - -Shared memory is memory that can be accessed by both the CPU and the accelerator. The use of shared memory eliminates or significantly reduces the overhead of copying data between the CPU and the accelerator. Although the memory is shared, it cannot be accessed concurrently by both the CPU and the accelerator, and doing so causes undefined behavior. The accelerator property [supports_cpu_shared_memory](reference/accelerator-class.md#supports_cpu_shared_memory) returns **`true`** if the accelerator supports shared memory, and the [default_cpu_access_type](reference/accelerator-class.md#default_cpu_access_type) property gets the default [access_type](reference/concurrency-namespace-enums-amp.md#access_type) for memory allocated on the `accelerator`—for example, **array**s associated with the `accelerator`, or `array_view` objects accessed on the `accelerator`. - -The C++ AMP runtime automatically chooses the best default `access_type` for each `accelerator`, but the performance characteristics (bandwidth and latency) of shared memory can be worse than those of dedicated (non-shared) accelerator memory when reading from the CPU, writing from the CPU, or both. If shared memory performs as well as dedicated memory for reading and writing from the CPU, the runtime defaults to `access_type_read_write`; otherwise, the runtime chooses a more conservative default `access_type`, and allows the app to override it if the memory access patterns of its computation kernels benefit from a different `access_type`. - -The following code example shows how to determine whether the default accelerator supports shared memory, and then overrides its default access type and creates an `accelerator_view` from it. - -```cpp -#include -#include - -using namespace Concurrency; - -int main() -{ - accelerator acc = accelerator(accelerator::default_accelerator); - - // Early out if the default accelerator doesn't support shared memory. - if (!acc.supports_cpu_shared_memory) - { - std::cout << "The default accelerator does not support shared memory" << std::endl; - return 1; - } - - // Override the default CPU access type. - acc.set_default_cpu_access_type(access_type_read_write); - - // Create an accelerator_view from the default accelerator.

If you use an appropriate tile size and tiled algorithm, you can get even more acceleration from your C++ AMP code. The basic components of tiling are: - -- `tile_static` variables. The primary benefit of tiling is the performance gain from `tile_static` access. Access to data in `tile_static` memory can be significantly faster than access to data in the global space (`array` or `array_view` objects). An instance of a `tile_static` variable is created for each tile, and all threads in the tile have access to the variable. In a typical tiled algorithm, data is copied into `tile_static` memory once from global memory and then accessed many times from the `tile_static` memory. - -- [tile_barrier::wait Method](reference/tile-barrier-class.md#wait). A call to `tile_barrier::wait` suspends execution of the current thread until all of the threads in the same tile reach the call to `tile_barrier::wait`. You cannot guarantee the order that the threads will run in, only that no threads in the tile will execute past the call to `tile_barrier::wait` until all of the threads have reached the call. This means that by using the `tile_barrier::wait` method, you can perform tasks on a tile-by-tile basis rather than a thread-by-thread basis. A typical tiling algorithm has code to initialize the `tile_static` memory for the whole tile followed by a call to `tile_barrier::wait`. Code that follows `tile_barrier::wait` contains computations that require access to all the `tile_static` values. - -- Local and global indexing. You have access to the index of the thread relative to the entire `array_view` or `array` object and the index relative to the tile. Using the local index can make your code easier to read and debug. Typically, you use local indexing to access `tile_static` variables, and global indexing to access `array` and `array_view` variables. - -- [tiled_extent Class](../../parallel/amp/reference/tiled-extent-class.md) and [tiled_index Class](../../parallel/amp/reference/tiled-index-class.md).

The type parameters of the call to `extent::tile()`, `<2,3>`, specify that 2x3 tiles are created. Thus, the 8x9 matrix is tiled into 12 tiles, four rows and three columns. - -3. The `parallel_for_each` method is called by using a `tiled_index<2,3>` object (`t_idx`) as the index. The type parameters of the index (`t_idx`) must match the type parameters of the compute domain (`descriptions.extent.tile< 2, 3>()`). - -4. When each thread is executed, the index `t_idx` returns information about which tile the thread is in (`tiled_index::tile` property) and the location of the thread within the tile (`tiled_index::local` property). - -## Tile Synchronization—tile_static and tile_barrier::wait - -The previous example illustrates the tile layout and indices, but is not in itself very useful. Tiling becomes useful when the tiles are integral to the algorithm and exploit `tile_static` variables. Because all threads in a tile have access to `tile_static` variables, calls to `tile_barrier::wait` are used to synchronize access to the `tile_static` variables. Although all of the threads in a tile have access to the `tile_static` variables, there is no guaranteed order of execution of threads in the tile. The following example shows how to use `tile_static` variables and the `tile_barrier::wait` method to calculate the average value of each tile. Here are the keys to understanding the example: - -1. The rawData is stored in an 8x8 matrix. - -2. The tile size is 2x2. This creates a 4x4 grid of tiles and the averages can be stored in a 4x4 matrix by using an `array` object. There are only a limited number of types that you can capture by reference in an AMP-restricted function. The `array` class is one of them. - -3. The matrix size and sample size are defined by using `#define` statements, because the type parameters to `array`, `array_view`, `extent`, and `tiled_index` must be constant values. You can also use `const int static` declarations. As an additional benefit, it is trivial to change the sample size to calculate the average over 4x4 tiles. - -4. A `tile_static` 2x2 array of float values is declared for each tile. Although the declaration is in the code path for every thread, only one array is created for each tile in the matrix. - -5. There is a line of code to copy the values in each tile to the `tile_static` array. For each thread, after the value is copied to the array, execution on the thread stops due to the call to `tile_barrier::wait`. - -6. When all of the threads in a tile have reached the barrier, the average can be calculated. Because the code executes for every thread, there is an `if` statement to only calculate the average on one thread. The average is stored in the averages variable. The barrier is essentially the construct that controls calculations by tile, much as you might use a **`for`** loop. - -7. The data in the `averages` variable, because it is an `array` object, must be copied back to the host. This example uses the vector conversion operator. - -8. In the complete example, you can change SAMPLESIZE to 4 and the code executes correctly without any other changes. - -```cpp -#include -#include -using namespace concurrency; - -#define SAMPLESIZE 2 -#define MATRIXSIZE 8 -void SamplingExample() { - - // Create data and array_view for the matrix. - std::vector rawData; - for (int i = 0; i < MATRIXSIZE * MATRIXSIZE; i++) { - rawData.push_back((float)i); - } - extent<2> dataExtent(MATRIXSIZE, MATRIXSIZE); - array_view matrix(dataExtent, rawData); - - // Create the array for the averages. - // There is one element in the output for each tile in the data. - std::vector outputData; - int outputSize = MATRIXSIZE / SAMPLESIZE; - for (int j = 0; j < outputSize * outputSize; j++) { - outputData.push_back((float)0); - } - extent<2> outputExtent(MATRIXSIZE / SAMPLESIZE, MATRIXSIZE / SAMPLESIZE); - array averages(outputExtent, outputData.begin(), outputData.end()); - - // Use tiles that are SAMPLESIZE x SAMPLESIZE. - // Find the average of the values in each tile. - // The only reference-type variable you can pass into the parallel_for_each call - // is a concurrency::array. - parallel_for_each(matrix.extent.tile(), - [=, &averages] (tiled_index t_idx) restrict(amp) - { - // Copy the values of the tile into a tile-sized array. - tile_static float tileValues[SAMPLESIZE][SAMPLESIZE]; - tileValues[t_idx.local[0]][t_idx.local[1]] = matrix[t_idx]; - - // Wait for the tile-sized array to load before you calculate the average. - t_idx.barrier.wait(); - - // If you remove the if statement, then the calculation executes for every - // thread in the tile, and makes the same assignment to averages each time. - if (t_idx.local[0] == 0 && t_idx.local[1] == 0) { - for (int trow = 0; trow < SAMPLESIZE; trow++) { - for (int tcol = 0; tcol < SAMPLESIZE; tcol++) { - averages(t_idx.tile[0],t_idx.tile[1]) += tileValues[trow][tcol]; - } - } - averages(t_idx.tile[0],t_idx.tile[1]) /= (float) (SAMPLESIZE * SAMPLESIZE); - } - }); - - // Print out the results. - // You cannot access the values in averages directly.

The second problem is that there is a race condition on the assignment to `total`, because all of the threads in the tile have access to the variable in no particular order. You could program an algorithm to only allow one thread to access the total at each barrier, as shown next. However, this solution is not extensible. - -```cpp -// Do not do this. -tile_static float total; -if (t_idx.local[0] == 0&& t_idx.local[1] == 0) { - total = matrix[t_idx]; -} -t_idx.barrier.wait(); - -if (t_idx.local[0] == 0&& t_idx.local[1] == 1) { - total += matrix[t_idx]; -} -t_idx.barrier.wait(); - -// etc. -``` - -## Memory Fences - -There are two kinds of memory accesses that must be synchronized—global memory access and `tile_static` memory access. A `concurrency::array` object allocates only global memory. A `concurrency::array_view` can reference global memory, `tile_static` memory, or both, depending on how it was constructed. There are two kinds of memory that must be synchronized: - -- global memory - -- `tile_static` - -A *memory fence* ensures that memory accesses are available to other threads in the thread tile, and that memory accesses are executed according to program order. To ensure this, compilers and processors do not reorder reads and writes across the fence. In C++ AMP, a memory fence is created by a call to one of these methods: - -- [tile_barrier::wait Method](reference/tile-barrier-class.md#wait): Creates a fence around both global and `tile_static` memory. - -- [tile_barrier::wait_with_all_memory_fence Method](reference/tile-barrier-class.md#wait_with_all_memory_fence): Creates a fence around both global and `tile_static` memory. - -- [tile_barrier::wait_with_global_memory_fence Method](reference/tile-barrier-class.md#wait_with_global_memory_fence): Creates a fence around only global memory. - -- [tile_barrier::wait_with_tile_static_memory_fence Method](reference/tile-barrier-class.md#wait_with_tile_static_memory_fence): Creates a fence around only `tile_static` memory. - -Calling the specific fence that you require can improve the performance of your app. The barrier type affects how the compiler and the hardware reorder statements. For example, if you use a global memory fence, it applies only to global memory accesses and therefore, the compiler and the hardware might reorder reads and writes to `tile_static` variables on the two sides of the fence. - -In the next example, the barrier synchronizes the writes to `tileValues`, a `tile_static` variable. In this example, `tile_barrier::wait_with_tile_static_memory_fence` is called instead of `tile_barrier::wait`. - -```cpp -// Using a tile_static memory fence. -parallel_for_each(matrix.extent.tile(), - [=, &averages] (tiled_index t_idx) restrict(amp) -{ - // Copy the values of the tile into a tile-sized array. - tile_static float tileValues[SAMPLESIZE][SAMPLESIZE]; - tileValues[t_idx.local[0]][t_idx.local[1]] = matrix[t_idx]; - - // Wait for the tile-sized array to load before calculating the average. - t_idx.barrier.wait_with_tile_static_memory_fence(); - - // If you remove the if statement, then the calculation executes - // for every thread in the tile, and makes the same assignment to - // averages each time. - if (t_idx.local[0] == 0&& t_idx.local[1] == 0) { - for (int trow = 0; trow -[tile_static Keyword](../../cpp/tile-static-keyword.md) diff --git a/docs/parallel/amp/walkthrough-debugging-a-cpp-amp-application.md b/docs/parallel/amp/walkthrough-debugging-a-cpp-amp-application.md deleted file mode 100644 index d9c3ddfd4e3..00000000000 --- a/docs/parallel/amp/walkthrough-debugging-a-cpp-amp-application.md +++ /dev/null @@ -1,405 +0,0 @@ ---- -description: "Learn more about: Walkthrough: Debugging a C++ AMP application" -title: "Walkthrough: Debugging a C++ AMP application" -ms.date: 10/27/2021 -helpviewer_keywords: ["debugging, C++ Accelerated Massive Parallelism", "C++ AMP, debugging", "C++ Accelerated Massive Parallelism, debugging", "debugging, C++ AMP"] ---- -# Walkthrough: Debugging a C++ AMP application - -This article demonstrates how to debug an application that uses C++ Accelerated Massive Parallelism (C++ AMP) to take advantage of the graphics processing unit (GPU).

To open the **GPU Threads** window, on the menu bar, choose **Debug** > **Windows** > **GPU Threads**. - - You can inspect the state the GPU threads in the **GPU Threads** window that appears. - -2. Dock the **GPU Threads** window at the bottom of Visual Studio. Choose the **Expand Thread Switch** button to display the tile and thread text boxes. The **GPU Threads** window shows the total number of active and blocked GPU threads, as shown in the following illustration. - - ![GPU Threads window with 4 active threads.](../../parallel/amp/media/campc.png "GPU Threads window with 4 active threads")
- GPU Threads window - - 313 tiles get allocated for this computation. Each tile contains 32 threads. Because local GPU debugging occurs on a software emulator, there are four active GPU threads. The four threads execute the instructions simultaneously and then move on together to the next instruction. - - In the **GPU Threads** window, there are four GPU threads active and 28 GPU threads blocked at the [tile_barrier::wait](reference/tile-barrier-class.md#wait) statement defined at about line 21 (`t_idx.barrier.wait();`). All 32 GPU threads belong to the first tile, `tile[0]`. An arrow points to the row that includes the current thread. To switch to a different thread, use one of the following methods: - - - In the row for the thread to switch to in the **GPU Threads** window, open the shortcut menu and choose **Switch To Thread**. If the row represents more than one thread, you'll switch to the first thread according to the thread coordinates. - - - Enter the tile and thread values of the thread in the corresponding text boxes and then choose the **Switch Thread** button. - - The **Call Stack** window displays the call stack of the current GPU thread. - -### To use the Parallel Stacks window - -1. To open the **Parallel Stacks** window, on the menu bar, choose **Debug** > **Windows** > **Parallel Stacks**. - - You can use the **Parallel Stacks** window to simultaneously inspect the stack frames of multiple GPU threads. - -2. Dock the **Parallel Stacks** window at the bottom of Visual Studio. - -3. Make sure that **Threads** is selected in the list in the upper-left corner. In the following illustration, the **Parallel Stacks** window shows a call-stack focused view of the GPU threads that you saw in the **GPU Threads** window. - - ![Parallel Stacks window with 4 active threads.](../../parallel/amp/media/campd.png "Parallel Stacks window with 4 active threads")
- Parallel Stacks window - - 32 threads went from `_kernel_stub` to the lambda statement in the `parallel_for_each` function call and then to the `sum_kernel_tiled` function, where the parallel reduction occurs. 28 out of the 32 threads have progressed to the [`tile_barrier::wait`](reference/tile-barrier-class.md#wait) statement and remain blocked at line 22, while the other four threads remain active in the `sum_kernel_tiled` function at line 30. - - You can inspect the properties of a GPU thread. They're available in the **GPU Threads** window in the rich DataTip of the **Parallel Stacks** window. To see them, hover the pointer on the stack frame of `sum_kernel_tiled`. The following illustration shows the DataTip. - - ![DataTip for Parallel Stacks window.](../../parallel/amp/media/campe.png "DataTip for Parallel Stacks window")
- GPU thread DataTip - - For more information about the **Parallel Stacks** window, see [Using the Parallel Stacks Window](/visualstudio/debugger/using-the-parallel-stacks-window). - -### To use the Parallel Watch window - -1. To open the **Parallel Watch** window, on the menu bar, choose **Debug** > **Windows** > **Parallel Watch** > **Parallel Watch 1**. - - You can use the **Parallel Watch** window to inspect the values of an expression across multiple threads. - -2. Dock the **Parallel Watch 1** window to the bottom of Visual Studio. There are 32 rows in the table of the **Parallel Watch** window. Each corresponds to a GPU thread that appeared in both the GPU Threads window and the **Parallel Stacks** window. Now, you can enter expressions whose values you want to inspect across all 32 GPU threads. - -3. Select the **Add Watch** column header, enter `localIdx`, and then choose the **Enter** key. - -4. Select the **Add Watch** column header again, type `globalIdx`, and then choose the **Enter** key. - -5. Select the **Add Watch** column header again, type `localA[localIdx[0]]`, and then choose the **Enter** key. - - You can sort by a specified expression by selecting its corresponding column header. - - Select the **localA[localIdx[0]]** column header to sort the column. The following illustration shows the results of sorting by **localA[localIdx[0]]**. - - ![Parallel Watch window with sorted results.](../../parallel/amp/media/campf.png "Parallel Watch window with sorted results")
- Results of sort - - You can export the content in the **Parallel Watch** window to Excel by choosing the **Excel** button and then choosing **Open in Excel**. If you have Excel installed on your development computer, the button opens an Excel worksheet that contains the content. - -6. In the upper-right corner of the **Parallel Watch** window, there's a filter control that you can use to filter the content by using Boolean expressions. Enter `localA[localIdx[0]] > 20000` in the filter control text box and then choose the **Enter** key. - - The window now contains only threads on which the `localA[localIdx[0]]` value is greater than 20000. The content is still sorted by the `localA[localIdx[0]]` column, which is the sorting action you chose earlier. - -## Flagging GPU Threads - -You can mark specific GPU threads by flagging them in the **GPU Threads** window, the **Parallel Watch** window, or the DataTip in the **Parallel Stacks** window. If a row in the GPU Threads window contains more than one thread, flagging that row flags all threads contained in the row. - -### To flag GPU threads - -1. Select the **[Thread]** column header in the **Parallel Watch 1** window to sort by tile index and thread index. - -2. On the menu bar, choose **Debug** > **Continue**, which causes the four threads that were active to progress to the next barrier (defined at line 32 of AMPMapReduce.cpp). - -3. Choose the flag symbol on the left side of the row that contains the four threads that are now active. - - The following illustration shows the four active flagged threads in the **GPU Threads** window. - - ![GPU Threads window with flagged threads.](../../parallel/amp/media/campg.png "GPU Threads window with flagged threads")
- Active threads in the GPU Threads window - - The **Parallel Watch** window and the DataTip of the **Parallel Stacks** window both indicate the flagged threads. - -4. If you want to focus on the four threads that you flagged, you can choose to show only the flagged threads. It limits what you see in the **GPU Threads**, **Parallel Watch**, and **Parallel Stacks** windows. - - Choose the **Show Flagged Only** button on any of the windows or on the **Debug Location** toolbar. The following illustration shows the **Show Flagged Only** button on the **Debug Location** toolbar. - - ![Debug Location toolbar with Show Only Flagged icon.](../../parallel/amp/media/camph.png "Debug Location toolbar with Show Only Flagged icon")
- **Show Flagged Only** button - - Now the **GPU Threads**, **Parallel Watch**, and **Parallel Stacks** windows display only the flagged threads. - -## Freezing and Thawing GPU Threads - -You can freeze (suspend) and thaw (resume) GPU threads from either the **GPU Threads** window or the **Parallel Watch** window. You can freeze and thaw CPU threads the same way; for information, see [How to: Use the Threads Window](/visualstudio/debugger/how-to-use-the-threads-window). - -### To freeze and thaw GPU threads - -1. Choose the **Show Flagged Only** button to display all the threads. - -2. On the menu bar, choose **Debug** > **Continue**. - -3. Open the shortcut menu for the active row and then choose **Freeze**. - - The following illustration of the **GPU Threads** window shows that all four threads are frozen. - - ![GPU Threads windows showing frozen threads.](../../parallel/amp/media/campk.png "GPU Threads windows showing frozen threads")
- Frozen threads in the **GPU Threads** window - - Similarly, the **Parallel Watch** window shows that all four threads are frozen. - -4. On the menu bar, choose **Debug** > **Continue** to allow the next four GPU threads to progress past the barrier at line 22 and to reach the breakpoint at line 30. The **GPU Threads** window shows that the four previously frozen threads remain frozen and in the active state. - -5. On the menu bar, choose **Debug**, **Continue**. - -6. From the **Parallel Watch** window, you can also thaw individual or multiple GPU threads. - -### To group GPU threads - -1. On the shortcut menu for one of the threads in the **GPU Threads** window, choose **Group By**, **Address**. - - The threads in the **GPU Threads** window are grouped by address. The address corresponds to the instruction in disassembly where each group of threads is located. 24 threads are at line 22 where the [tile_barrier::wait Method](reference/tile-barrier-class.md#wait) is executed. 12 threads are at the instruction for the barrier at line 32. Four of these threads are flagged. Eight threads are at the breakpoint at line 30. Four of these threads are frozen. The following illustration shows the grouped threads in the **GPU Threads** window. - - ![GPU Threads window with threads grouped by Address.](../../parallel/amp/media/campl.png "GPU Threads window with threads grouped by Address")
- Grouped threads in the **GPU Threads** window - -2. You can also do the **Group By** operation by opening the shortcut menu for the **Parallel Watch** window's data grid. Select **Group By**, and then choose the menu item that corresponds to how you want to group the threads. - -## Running All Threads to a Specific Location in Code - -You run all the threads in a given tile to the line that contains the cursor by using **Run Current Tile To Cursor**. - -### To run all threads to the location marked by the cursor - -1. On the shortcut menu for the frozen threads, choose **Thaw**. - -2. In the **Code Editor**, put the cursor in line 30. - -3. On the shortcut menu for the **Code Editor**, choose **Run Current Tile To Cursor**. - - The 24 threads that were previously blocked at the barrier at line 21 have progressed to line 32.

The product is calculated by multiplying the rows of A by the columns of B element by element. - -![Diagram showing the result 3 by 3 product matrix.](../../parallel/amp/media/campmatrixproductnontiled.png) - -### To multiply without using C++ AMP - -1. Open MatrixMultiply.cpp and use the following code to replace the existing code. - - ```cpp - #include - - void MultiplyWithOutAMP() { - int aMatrix[3][2] = {{1, 4}, {2, 5}, {3, 6}}; - int bMatrix[2][3] = {{7, 8, 9}, {10, 11, 12}}; - int product[3][3] = {{0, 0, 0}, {0, 0, 0}, {0, 0, 0}}; - - for (int row = 0; row < 3; row++) { - for (int col = 0; col < 3; col++) { - // Multiply the row of A by the column of B to get the row, column of product. - for (int inner = 0; inner < 2; inner++) { - product[row][col] += aMatrix[row][inner] * bMatrix[inner][col]; - } - std::cout << product[row][col] << " "; - } - std::cout << "\n"; - } - } - - int main() { - MultiplyWithOutAMP(); - getchar(); - } - ``` - - The algorithm is a straightforward implementation of the definition of matrix multiplication. It does not use any parallel or threaded algorithms to reduce the computation time. - -1. On the menu bar, choose **File** > **Save All**. - -1. Choose the **F5** keyboard shortcut to start debugging and verify that the output is correct. - -1. Choose **Enter** to exit the application. - -### To multiply by using C++ AMP - -1. In MatrixMultiply.cpp, add the following code before the `main` method. - - ```cpp - void MultiplyWithAMP() { - int aMatrix[] = { 1, 4, 2, 5, 3, 6 }; - int bMatrix[] = { 7, 8, 9, 10, 11, 12 }; - int productMatrix[] = { 0, 0, 0, 0, 0, 0, 0, 0, 0 }; - - array_view a(3, 2, aMatrix); - - array_view b(2, 3, bMatrix); - - array_view product(3, 3, productMatrix); - - parallel_for_each(product.extent, - [=] (index<2> idx) restrict(amp) { - int row = idx[0]; - int col = idx[1]; - for (int inner = 0; inner <2; inner++) { - product[idx] += a(row, inner)* b(inner, col); - } - }); - - product.synchronize(); - - for (int row = 0; row <3; row++) { - for (int col = 0; col <3; col++) { - //std::cout << productMatrix[row*3 + col] << " "; - std::cout << product(row, col) << " "; - } - std::cout << "\n"; - } - } - ``` - - The AMP code resembles the non-AMP code. The call to `parallel_for_each` starts one thread for each element in `product.extent`, and replaces the **`for`** loops for row and column. The value of the cell at the row and column is available in `idx`. You can access the elements of an `array_view` object by using either the `[]` operator and an index variable, or the `()` operator and the row and column variables. The example demonstrates both methods. The `array_view::synchronize` method copies the values of the `product` variable back to the `productMatrix` variable. - -1. Add the following `include` and **`using`** statements at the top of MatrixMultiply.cpp. - - ```cpp - #include - using namespace concurrency; - ``` - -1.

Press the **Spacebar** to exit the application. - -## Multiplication with tiling - -Tiling is a technique in which you partition data into equal-sized subsets, which are known as tiles. Three things change when you use tiling. - -- You can create `tile_static` variables. Access to data in `tile_static` space can be many times faster than access to data in the global space. An instance of a `tile_static` variable is created for each tile, and all threads in the tile have access to the variable. The primary benefit of tiling is the performance gain due to `tile_static` access. - -- You can call the [tile_barrier::wait](reference/tile-barrier-class.md#wait) method to stop all of the threads in one tile at a specified line of code. You cannot guarantee the order that the threads will run in, only that all of the threads in one tile will stop at the call to `tile_barrier::wait` before they continue execution. - -- You have access to the index of the thread relative to the entire `array_view` object and the index relative to the tile. By using the local index, you can make your code easier to read and debug. - -To take advantage of tiling in matrix multiplication, the algorithm must partition the matrix into tiles and then copy the tile data into `tile_static` variables for faster access. In this example, the matrix is partitioned into submatrices of equal size. The product is found by multiplying the submatrices. The two matrices and their product in this example are: - -![Diagram showing 4 by 4 matrix A.](../../parallel/amp/media/campmatrixatiled.png) - -![Diagram showing 4 by 4 matrix B.](../../parallel/amp/media/campmatrixbtiled.png) - -![Diagram showing result 4 by 4 product matrix.](../../parallel/amp/media/campmatrixproducttiled.png) - -The matrices are partitioned into four 2x2 matrices, which are defined as follows: - -![Diagram showing 4 by 4 matrix A partitioned into 2 by 2 sub matrices.](../../parallel/amp/media/campmatrixapartitioned.png) - -![Diagram showing 4 by 4 matrix B partitioned into 2 by 2 sub matrices.](../../parallel/amp/media/campmatrixbpartitioned.png) - -The product of A and B can now be written and calculated as follows: - -![Diagram showing 4 by 4 matrix A B partitioned into 2 by 2 sub matrices.](../../parallel/amp/media/campmatrixproductpartitioned.png) - -Because matrices `a` through `h` are 2x2 matrices, all of the products and sums of them are also 2x2 matrices. It also follows that the product of A and B is a 4x4 matrix, as expected. To quickly check the algorithm, calculate the value of the element in the first row, first column in the product. In the example, that would be the value of the element in the first row and first column of `ae + bg`. You only have to calculate the first column, first row of `ae` and `bg` for each term. That value for `ae` is `(1 * 1) + (2 * 5) = 11`. The value for `bg` is `(3 * 1) + (4 * 5) = 23`. The final value is `11 + 23 = 34`, which is correct. - -To implement this algorithm, the code: - -- Uses a `tiled_extent` object instead of an `extent` object in the `parallel_for_each` call. - -- Uses a `tiled_index` object instead of an `index` object in the `parallel_for_each` call. - -- Creates `tile_static` variables to hold the submatrices. - -- Uses the `tile_barrier::wait` method to stop the threads for the calculation of the products of the submatrices. - -### To multiply by using AMP and tiling - -1. In MatrixMultiply.cpp, add the following code before the `main` method. - - ```cpp - void MultiplyWithTiling() { - // The tile size is 2. - static const int TS = 2; - - // The raw data. - int aMatrix[] = { 1, 2, 3, 4, 5, 6, 7, 8, 1, 2, 3, 4, 5, 6, 7, 8 }; - int bMatrix[] = { 1, 2, 3, 4, 5, 6, 7, 8, 1, 2, 3, 4, 5, 6, 7, 8 }; - int productMatrix[] = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; - - // Create the array_view objects. - array_view a(4, 4, aMatrix); - array_view b(4, 4, bMatrix); - array_view product(4, 4, productMatrix); - - // Call parallel_for_each by using 2x2 tiles. - parallel_for_each(product.extent.tile(), - [=] (tiled_index t_idx) restrict(amp) - { - // Get the location of the thread relative to the tile (row, col) - // and the entire array_view (rowGlobal, colGlobal). - int row = t_idx.local[0]; - int col = t_idx.local[1]; - int rowGlobal = t_idx.global[0]; - int colGlobal = t_idx.global[1]; - int sum = 0; - - // Given a 4x4 matrix and a 2x2 tile size, this loop executes twice for each thread. - // For the first tile and the first loop, it copies a into locA and e into locB. - // For the first tile and the second loop, it copies b into locA and g into locB. - for (int i = 0; i < 4; i += TS) { - tile_static int locA[TS][TS]; - tile_static int locB[TS][TS]; - locA[row][col] = a(rowGlobal, col + i); - locB[row][col] = b(row + i, colGlobal); - // The threads in the tile all wait here until locA and locB are filled. - t_idx.barrier.wait(); - - // Return the product for the thread. The sum is retained across - // both iterations of the loop, in effect adding the two products - // together, for example, a*e. - for (int k = 0; k < TS; k++) { - sum += locA[row][k] * locB[k][col]; - } - - // All threads must wait until the sums are calculated. If any threads - // moved ahead, the values in locA and locB would change. - t_idx.barrier.wait(); - // Now go on to the next iteration of the loop. - } - - // After both iterations of the loop, copy the sum to the product variable by using the global location. - product[t_idx.global] = sum; - }); - - // Copy the contents of product back to the productMatrix variable. - product.synchronize(); - - for (int row = 0; row <4; row++) { - for (int col = 0; col <4; col++) { - // The results are available from both the product and productMatrix variables. - //std::cout << productMatrix[row*3 + col] << " "; - std::cout << product(row, col) << " "; - } - std::cout << "\n"; - } - } - ``` - - This example is significantly different than the example without tiling. The code uses these conceptual steps: - 1. Copy the elements of tile[0,0] of `a` into `locA`. Copy the elements of tile[0,0] of `b` into `locB`. Notice that `product` is tiled, not `a` and `b`. Therefore, you use global indices to access `a, b`, and `product`. The call to `tile_barrier::wait` is essential. It stops all of the threads in the tile until both `locA` and `locB` are filled. - - 1. Multiply `locA` and `locB` and put the results in `product`. - - 1. Copy the elements of tile[0,1] of `a` into `locA`. Copy the elements of tile [1,0] of `b` into `locB`. - - 1. Multiply `locA` and `locB` and add them to the results that are already in `product`. - - 1. The multiplication of tile[0,0] is complete. - - 1. Repeat for the other four tiles. There is no indexing specifically for the tiles and the threads can execute in any order. As each thread executes, the `tile_static` variables are created for each tile appropriately and the call to `tile_barrier::wait` controls the program flow. - - 1. As you examine the algorithm closely, notice that each submatrix is loaded into a `tile_static` memory twice. That data transfer does take time. However, once the data is in `tile_static` memory, access to the data is much faster. Because calculating the products requires repeated access to the values in the submatrices, there is an overall performance gain. For each algorithm, experimentation is required to find the optimal algorithm and tile size. - - In the non-AMP and non-tile examples, each element of A and B is accessed four times from the global memory to calculate the product. In the tile example, each element is accessed twice from the global memory and four times from the `tile_static` memory. That is not a significant performance gain. However, if the A and B were 1024x1024 matrices and the tile size were 16, there would be a significant performance gain. In that case, each element would be copied into `tile_static` memory only 16 times and accessed from `tile_static` memory 1024 times. - -1.

If you didn't already upgrade the project, the agent guides you through that process before creating its assessment. After ensuring that your project is upgraded, the agent builds your codebase, analyzes the reported warnings and errors, and generates an `assessment.md` file that describes the problems that it found, their severity, and other useful information. This is your opportunity to tell the agent any other context that could help it make a plan. + +One of the things you might choose to do here is to tell the agent not to fix certain discovered problems, because you know that resolving them involves some strategic decisions or because they were preexisting warnings that you decided are acceptable for your project.

Once you approve the assessment, the agent moves on to creating a concrete plan on addressing the problems. + +### Planning stage + +Based on the approved assessment and any other context or instructions you provide, the agent creates a `plan.md` file that proposes a detailed plan for resolving each of the identified problems. If the agent produces a plan that doesn't match your organization's coding style or practices, you can provide that guidance to the agent and have it solve the problem differently. After you agree on the plan, the agent moves to the execution stage. + +### Execution stage + +Now that the agent has a plan, it breaks down the necessary tasks to execute the plan. You can define these tasks as finely as you want. The tasks can even include steps to work on a branch or to commit specific changes together in the same commit. After making any changes, the agent builds the project again to confirm that the problems are resolved. If the problems aren't resolved, the agent iterates with you until they're resolved to your satisfaction. + +### Post-upgrade validation + +When the agent finishes, run the changes through any testing infrastructure you have. Have a colleague review the changes in a pull request. Since this feature is currently in preview, you might receive an infobar to complete a product survey to let the product team know how the agent performed on your codebase. The product team looks forward to hearing how they can improve the agent to solve your problems and accelerate your upgrade and modernization efforts. \ No newline at end of file diff --git a/docs/porting/features-deprecated-in-visual-studio.md b/docs/porting/features-deprecated-in-visual-studio.md index 71383dbc034..21848bb9152 100644 --- a/docs/porting/features-deprecated-in-visual-studio.md +++ b/docs/porting/features-deprecated-in-visual-studio.md @@ -1,21 +1,61 @@ --- -description: "Learn more about: C++ features deprecated in Visual Studio" -title: "C++ features deprecated in Visual Studio" -ms.date: 04/07/2022 -helpviewer_keywords: ["Features deprecated in Visual Studio"] +description: "Learn more about: C++ features deprecated or removed from Visual Studio" +title: "C++ features deprecated or removed from Visual Studio" +ms.date: 05/11/2026 +helpviewer_keywords: ["Features deprecated or removed from Visual Studio"] --- -# C++ features deprecated in Visual Studio +# C++ features deprecated or removed from Visual Studio -This article is a non-exhaustive list of C++ features deprecated in Visual Studio 2019 and 2022.

In general, the new results are correct to within the limits specified by the language standard. Read on to find out what's changed, and if it's important, how to get the same results your functions got before. ## New math functions and Universal CRT changes -Most CRT math functions have been available in Visual Studio for years, but starting in Visual Studio 2013, all of the functions required by ISO C99 are included. These functions are implemented to balance performance with correctness. Because producing the correctly rounded result in every case may be prohibitively expensive, these functions are designed to efficiently produce a close approximation to the correctly rounded result. In most cases, the result produced is within +/-1 unit of least precision, or *ulp*, of the correctly rounded result, though there may be cases where there is greater inaccuracy. If you were using a different math library to get these functions before, implementation differences may be responsible for the change in your results. +Most CRT math functions have been available in Visual Studio for years, but starting in Visual Studio 2013, all of the functions required by ISO C99 are included.

These changes can lead to detectable differences in the results of floating-point calculations that use these functions. The functions that had bug issues were erf, exp2, remainder, remquo, scalbln, and scalbn, and their float and long double variants.

Other changes in Visual Studio 2015 fixed issues in preserving floating point status word and exception state information in `_clear87`, `_clearfp`, `fegetenv`, `fesetenv`, and `feholdexcept` functions. ## Processor differences and compiler flags -Many of the floating point math library functions have different implementations for different CPU architectures. For example, the 32-bit x86 CRT may have a different implementation than the 64-bit x64 CRT. In addition, some of the functions may have multiple implementations for a given CPU architecture. The most efficient implementation is selected dynamically at run-time depending on the instruction sets supported by the CPU. For example, in the 32-bit x86 CRT, some functions have both an x87 implementation and an SSE2 implementation. When running on a CPU that supports SSE2, the faster SSE2 implementation is used. When running on a CPU that does not support SSE2, the slower x87 implementation is used. You may see this when migrating old code, because the default x86 compiler architecture option changed to [/arch:SSE2](../build/reference/arch-x86.md) in Visual Studio 2012. Because different implementations of the math library functions may use different CPU instructions and different algorithms to produce their results, the functions may produce different results on different platforms. In most cases, the results are within +/-1 ulp of the correctly rounded result, but the actual results may vary across CPUs. +Many of the floating point math library functions have different implementations for different CPU architectures.

For example, the code generated by Visual Studio 2010 when [/fp:precise](../build/reference/fp-specify-floating-point-behavior.md) (the default) or `/fp:strict` was specified may not have propagated intermediate not-a-number (NaN) values through expressions correctly. Thus, some expressions that gave a numeric result in older compilers may now correctly produce a NaN result. You may also see differences because the code optimizations enabled for `/fp:fast` now take advantage of more processor features. These optimizations can use fewer instructions, but may impact the generated results because some previously visible intermediate operations have been removed. +Code-generation improvements in various floating-point modes can also alter floating-point results when comparing old code to new code, even with identical compiler flags.

You may even see better processor power performance when SSE2 instructions replace x87 instructions. However, if you have code that must precisely replicate the floating point behavior of an older compiler, consider using Visual Studio native multi-targeting capabilities, and build the affected project with the older toolset.

For more information, see [Overview of potential upgrade issues](overview-of-potential-upgrade-issues-visual-cpp.md). When you upgrade an application from Visual Studio 2015 or later, it isn't necessary to upgrade dependencies because the code generated by those versions is binary-compatible. For more information, see [C++ binary compatibility between Visual Studio versions](binary-compat-2015-2017.md). ## Use vcpkg for open-source libraries -In the past, finding and upgrading third-party libraries was sometimes a non-trivial task. To make it easier to acquire and rebuild C++ third-party open-source libraries, the Visual C++ team has created a command-line tool called the **VC++ Packaging Tool** or **vcpkg**. Vcpkg has a searchable catalog of many popular C++ open-source libraries. You can install any library in the catalog directly from the vcpkg command line. When you install a library, Vcpkg creates a directory tree on your machine and adds the *`.h`* files, the *`.lib`* files, and binaries in this folder. You can use this folder in your compilation command line, or integrate it into Visual Studio 2015 or later by using the `vcpkg integrate install` command. After you integrate a library location, Visual Studio can find it and add it to any new project that you create. To use a library, just `#include` it. Visual Studio will automatically add the library path to your project settings and copy the DLL to your solution folder. For more information, see [vcpkg](/vcpkg/). +In the past, finding and upgrading third-party libraries was sometimes a non-trivial task. To make it easier to acquire and rebuild C++ third-party open-source libraries, the Microsoft C++ team has created a command-line tool called **[vcpkg](https://vcpkg.io)**.

You can either install [vcpkg from GitHub](https://github.com/microsoft/vcpkg/) or use the built-in version that ships with Visual Studio 2022 or later. To learn more about vcpkg, see the [vcpkg documentation](/vcpkg). ## Reporting issues -If your open-source library isn't found in the **vcpkg** catalog, you can open an issue on the [GitHub repo](https://github.com/Microsoft/vcpkg/issues). That's where the community and the Visual C++ team can see it and potentially create the port file for this library. +If your open-source library isn't found in the **vcpkg** curated registry, you can open an issue on the [GitHub repo](https://github.com/Microsoft/vcpkg/issues).

For more information, see [CMake projects in Visual Studio](../build/cmake-projects-in-visual-studio.md) - -## Reasons to upgrade C++ code - -If a legacy application is running satisfactorily, in a secure environment, and isn't under active development, there might not be much incentive to upgrade it. However, consider an upgrade in these cases: Your application requires ongoing maintenance. Or, you're doing new feature development, or making performance or security improvements. An upgrade brings these benefits: - -- The same code can run faster, because we've improved compiler optimizations. - -- Modern C++ features and programming practices eliminate many common causes of bugs, and produce code that's far easier to maintain than older C-style idioms. - -- Build times are faster, because of performance improvements in the compiler and linker. -- Better standards conformance. The [/permissive-](../build/reference/permissive-standards-conformance.md) compiler option helps you identify code that doesn't conform to the current C++ standard. The [new preprocessor](../preprocessor/preprocessor-experimental-overview.md) supports code conformance, too. - -- Better run-time security, including more secure [C Runtime library](../c-runtime-library/security-features-in-the-crt.md) features. And, compiler features such as [guard checking](../build/reference/guard-enable-guard-checks.md) and address sanitizers (new in Visual Studio 2019 version 16.4). - -## Multitargeting vs. upgrading - -Perhaps upgrading your code base to a new toolset isn't an option for you. You can still use the latest Visual Studio to build and edit projects that use older toolsets and libraries. In Visual Studio 2019, you can take advantage of features such as: - -- modern static analysis tools, including the C++ Core Guidelines checkers and Clang-Tidy, to help identify potential problems in your source code. - -- automatic formatting according to your choice of modern styles can help make legacy code much more readable. - -For more information, see [Use native multi-targeting in Visual Studio to build old projects](use-native-multi-targeting.md). - -## In this section +# Microsoft C++ porting and upgrading guide -| Title | Description | -|--|--| -| [Upgrading C++ projects from earlier versions of Visual Studio](upgrading-projects-from-earlier-versions-of-visual-cpp.md) | How to upgrade your code base to the latest version of Visual Studio and the compiler. | -| [IDE tools for upgrading C++ code](ide-tools-for-upgrading-code.md) | Useful IDE features that help in the upgrade process. | -| [C++ binary compatibility between Visual Studio versions](binary-compat-2015-2017.md) | Consume v140 and later libraries as-is from v140 and later projects. | -| [Use native multi-targeting in Visual Studio to build old projects](use-native-multi-targeting.md) | Use Visual Studio with older compilers and libraries. | -| [Visual C++ change history 2003 - 2015](visual-cpp-change-history-2003-2015.md) | A list of all the changes in the Microsoft C++ libraries and build tools from Visual Studio 2003 through 2015 that might require changes in your code. | -| [Visual C++ What's New 2003 through 2015](visual-cpp-what-s-new-2003-through-2015.md) | All the "what's new" information for Microsoft C++ from Visual Studio 2003 through Visual Studio 2015. | -| [Porting and Upgrading: Examples and Case Studies](porting-and-upgrading-examples-and-case-studies.md) | For this section, we ported and upgrades several samples and applications and discussed the experiences and results.

For user-mode ASan, the compiler and runtime are updated together because Visual Studio provides both. [Kernel-mode ASan (KASan)](/windows-hardware/drivers/devtest/kasan) is part of the Windows OS, so it updates on a different cadence than the compiler. To avoid issues with a new compiler using new intrinsics that the installed version of KASan doesn't support, link the compatibility library (`asan_compat.lib`) to avoid link-time issues. When using `asan_compat.lib`, the program behaves as though the unsupported ASan intrinsics aren't used. Linking with a newer runtime library that supports the new ASan intrinsics supersedes the versions provided by `asan_compat.lib`. This decision is made at link time, so it's imperative to link with the KASan library provided by the Windows SDK that matches the OS version you're targeting. + +The following options are supported in Visual Studio 2022 17.14 Preview 2 and later: +- To include this compatibility library as a default library, use the **`/fsanitize-address-asan-compat-lib`** compiler option.

This call looks like a call to a function, but it's actually calling `operator()` of the `LessThanFunctor` type. This similarity between calling a function object and a function is how the term function object came about. ## Function Objects and Containers -The C++ Standard Library contains several function objects in the [``](../standard-library/functional.md) header file. One use of these function objects is as a sorting criterion for containers. For example, the `set` container is declared as follows: +The C++ Standard Library contains several function objects in the [``](functional.md) header file.

This function object returns **`true`** if the first parameter is less than the second parameter. Since some containers sort their elements, the container needs a way of comparing two elements.

The comparison is done by using the function object. You can define your own sorting criteria for containers by creating a function object and specifying it in the template list for the container. ## Function Objects and Algorithms -Another use of functional objects is in algorithms. For example, the `remove_if` algorithm is declared as follows: +Another use of function objects is in algorithms. For example, the [`remove_if`](algorithm-functions.md#remove_if) algorithm is declared as follows: ```cpp -template +template ForwardIterator remove_if( ForwardIterator first, ForwardIterator last, - Predicate pred); + UnaryPredicate pred); ``` -The last argument to `remove_if` is a function object that returns a boolean value (a *predicate*). If the result of the function object is **`true`**, then the element is removed from the container being accessed by the iterators `first` and `last`. You can use any of the function objects declared in the [``](../standard-library/functional.md) header for the argument `pred` or you can create your own. +The last argument to `remove_if` is a function object that returns a boolean value (a *predicate*). If the result of the function object is **`true`**, then the element is shifted such that it's beyond the new end returned by `remove_if`. You can use any of the function objects declared in the [``](functional.md) header for the argument `pred` or you can create your own. ## See also -[C++ Standard Library Reference](../standard-library/cpp-standard-library-reference.md) +[C++ Standard Library Reference](cpp-standard-library-reference.md) diff --git a/docs/standard-library/future-enums.md b/docs/standard-library/future-enums.md index 087f8291808..565311c0645 100644 --- a/docs/standard-library/future-enums.md +++ b/docs/standard-library/future-enums.md @@ -1,19 +1,16 @@ --- -description: "Learn more about: enums" title: " enums" -ms.date: "11/04/2016" +description: "Learn more about: enums" +ms.date: 11/04/2016 f1_keywords: ["future/std::future_errc", "future/std::future_status", "future/std::launch"] -ms.assetid: 8c675645-db47-4cab-bc0e-7b87f8a302df --- # `` enums -[future_errc](#future_errc)\ -[future_status](#future_status)\ -[launch](#launch) +The `` header provides the following enums: -## future_errc Enumeration +## `future_errc` enumeration -Supplies symbolic names for all of the errors that are reported by the [future_error](../standard-library/future-error-class.md) class. +Supplies symbolic names for all of the errors that are reported by the [`future_error`](../standard-library/future-error-class.md) class. ```cpp class future_errc { @@ -24,7 +21,7 @@ class future_errc { };

In general, the elements need be merely less than comparable to establish this order: so that, given any two elements, it may be determined either that they're equivalent (in the sense that neither is less than the other) or that one is less than the other. This results in an ordering between the nonequivalent elements. On a more technical note, the comparison function is a binary predicate that induces a strict weak ordering in the standard mathematical sense. A binary predicate f(x y) is a function object that has two argument objects `x` and `y` and a return value of **`true`** or **`false`**. An ordering imposed on a `hash_map` is a strict weak ordering if the binary predicate is irreflexive, antisymmetric, and transitive and if equivalence is transitive, where two objects `x` and `y` are defined to be equivalent when both f(x, y) and f(y, x) are `false`. If the stronger condition of equality between keys replaces that of equivalence, then the ordering becomes total (in the sense that all the elements are ordered with respect to each other) and the keys matched will be indiscernible from each other. @@ -371,8 +371,6 @@ Erases all the elements of a `hash_map`. void clear(); ``` -### Remarks - ### Example The following example demonstrates the use of the `hash_map::clear` member function. @@ -463,8 +461,6 @@ A type that provides a reference to a **`const`** element stored in a `hash_map` typedef list::const_reference const_reference; ``` -### Remarks - ### Example ```cpp @@ -516,7 +512,7 @@ The data value of the first element in the hash_map is 10.

In general, the elements need be merely less than comparable to establish this order: so that, given any two elements, it may be determined either that they're equivalent (in the sense that neither is less than the other) or that one is less than the other. This results in an ordering between the nonequivalent elements.

This comparison function is a function object of class `Traits`. To work with `priority_queue`, your elements only need to support comparison using the less-than operator (`<`) so that it can arrange the elements in order. -Suitable underlying container classes for `priority_queue` include [`deque` Class](../standard-library/deque-class.md) and the default [`vector` Class](../standard-library/vector-class.md) or any other sequence container that supports the operations of `front`, `push_back`, and `pop_back` and a random-access iterator.

You may want to do that for performance reasons. The default, `vector`, is usually best for cache locality because elements are stored in contiguous storage, and does fewer allocations as it grows.

This allows you to create a `scoped_lock` object without locking the mutexes again, which can be useful in certain scenarios where you have already acquired the locks and want to manage their lifetime with a `scoped_lock`. + +The `scoped_lock` class manages locking and unlocking of one or more mutexes throughout a scope. When you create a `scoped_lock` object, it acquires ownership of the mutexes passed to it. When the `scoped_lock` object is destroyed (for example, when it goes out of scope), the mutexes are released. This ensures that mutexes are always properly released, even if an exception is thrown. + +If you need to lock only a single mutex, consider using [`lock_guard`](lock-guard-class.md) or [`unique_lock`](unique-lock-class.md). Use `scoped_lock` when you need to lock multiple mutexes simultaneously without risk of deadlock. + +The `scoped_lock` class isn't copyable. + +If only one mutex type is passed to `scoped_lock`, the `scoped_lock` provides a type alias named `mutex_type` that refers to that one mutex type. However, if you create a `scoped_lock` with two or more mutex types, the `mutex_type` alias does not exist because `mutex_type` only makes sense when there is a single underlying mutex type.

In general, the elements need to be merely less than comparable to establish this order so that, given any two elements, it may be determined either that they're equivalent (in the sense that neither is less than the other) or that one is less than the other. This results in an ordering between the nonequivalent elements.

The third constructor constructs an object that's associated with the thread that's associated with `Other`. `Other` is then set to a default-constructed state. diff --git a/docs/standard-library/thread-functions.md b/docs/standard-library/thread-functions.md index eea1f7215e9..ed86df6516b 100644 --- a/docs/standard-library/thread-functions.md +++ b/docs/standard-library/thread-functions.md @@ -1,65 +1,80 @@ --- -description: "Learn more about: functions" title: " functions" -ms.date: "11/04/2016" +description: "Learn more about: functions" +ms.date: 11/04/2016 f1_keywords: ["thread/std::get_id", "thread/std::sleep_for", "thread/std::sleep_until", "thread/std::swap", "thread/std::yield"] -ms.assetid: bb1aa1ef-fe3f-4e2c-8b6e-e22dbf2f5a19 helpviewer_keywords: ["std::get_id [C++]", "std::sleep_for [C++]", "std::sleep_until [C++]", "std::swap [C++]", "std::yield [C++]"] --- # `` functions -## get_id +The `` header provides the following functions: + +## `get_id` Uniquely identifies the current thread of execution. ```cpp -thread::id this_thread::get_id() noexcept; +thread::id get_id() noexcept; ``` ### Return Value -An object of type [thread::id](../standard-library/thread-class.md) that uniquely identifies the current thread of execution. +An object of type [`thread::id`](thread-class.md#id_class) that uniquely identifies the current thread of execution. + +### Example + +```cpp +#include +#include + +int main() +{ + std::thread::id current_thread_id = std::this_thread::get_id(); + std::cout << "Current thread id: " << current_thread_id; +} +``` -## sleep_for +```Output +Current thread id: 16196 +``` + +## `sleep_for` Blocks the calling thread. ```cpp -template -inline void sleep_for(const chrono::duration& Rel_time); +template +void sleep_for(const chrono::duration& Rel_time); ``` ### Parameters -*Rel_time*\ -A [duration](../standard-library/duration-class.md) object that specifies a time interval. +*`Rel_time`*\ +A [`duration`](duration-class.md) object that specifies a time interval. ### Remarks -The function blocks the calling thread for at least the time that's specified by *Rel_time*.
