Description

Instruction.MatchCall() and similar throw NullReferenceException because MonoMod.Utils.Extensions.Is(this MethodReference method, ...) tries to do method.DeclaringType.Whatever() and DeclaringType is null on dynamic methods

Relevant extension methods:

• MonoMod/src/MonoMod.Utils/Extensions.UtilsIL.cs

  Line 60 in f2da9f5

  public static bool Is(this MethodReference method, string typeFullName, string name)

• MonoMod/src/MonoMod.Utils/Extensions.UtilsIL.cs

  Line 77 in f2da9f5

  public static bool Is(this MethodReference method, Type type, string name)

Example

var dynamicMethod = new System.Reflection.Emit.DynamicMethod("method", typeof(void), [], true);

var dmd = new DynamicMethodDefinition("", null, []);
var il = dmd.GetILProcessor();

var instr = il.Create(OpCodes.Call, dynamicMethod);

instr.MatchCall("TestType", "TestName");
