Requirement

  • build kernel using clang into binary successfully
  • golang
  • The related kernel module are enabled in Linux kernel configuration

Build Linux kernel into LLVM Bitcode

go run path/of/v5.12/KernelBitcode.go --help
  1. Build Kernel with clang
make LLVM=<Path_to_llvm> -j16

Note

You can find out your llvm-* or clang in the Path_to_llvm

  1. Generate script to build kernel into LLVM Bitcode
go run path/of/v5.12/KernelBitcode.go

Important

If you do not use the llvm installed by the system but compile your own llvm version, you need to modify the specified parameters by viewing the -help parameter

  1. Get LLVM Bitcode
bash build.sh

built-in.bc is in each directory. All external modules are in the end of build.sh. Now you can perform analysis on those LLVM bitcode files.
