Pull request overview

This pull request adds support for async thunk methods in GetNativeCodeInfo by enabling the debugger DAC to resolve async thunk methods to their actual implementation method descriptors. The runtime caches async thunks in the methoddef map, which causes the debugger to incorrectly return data for the thunk instead of the actual method. This PR addresses that by:

  1. Adding DAC support to the generic method infrastructure (genmeth.cpp, instmethhash.cpp, generics.cpp)
  2. Creating a new GetAsyncOtherVariantNoCreate method that finds async variants without creating new ones (DAC-safe)
  3. Using this new method in GetNativeCodeInfo to resolve async thunk methods to their actual implementations

Changes:

  • Added DAC compilation support to generic method code by moving genmeth.cpp to DAC+WKS build and adding appropriate DACCESS_COMPILE guards
  • Created GetAsyncOtherVariantNoCreate method to look up async method variants without allocation
  • Modified GetNativeCodeInfo to resolve async thunk methods to actual methods using the new lookup function

Pull request overview

This pull request adds support for async thunk methods in GetNativeCodeInfo by enabling the debugger DAC to resolve async thunk methods to their actual implementation method descriptors. The runtime caches async thunks in the methoddef map, which causes the debugger to incorrectly return data for the thunk instead of the actual method. This PR addresses that by:

  1. Adding DAC support to the generic method infrastructure (genmeth.cpp, instmethhash.cpp, generics.cpp)
  2. Creating a new GetAsyncOtherVariantNoCreate method that finds async variants without creating new ones (DAC-safe)
  3. Using this new method in GetNativeCodeInfo to resolve async thunk methods to their actual implementations

Changes:

  • Added DAC compilation support to generic method code by moving genmeth.cpp to DAC+WKS build and adding appropriate DACCESS_COMPILE guards
  • Created GetAsyncOtherVariantNoCreate method to look up async method variants without allocation
  • Modified GetNativeCodeInfo to resolve async thunk methods to actual methods using the new lookup function
