Member Function Documentation

◆ writeResolverCode()

void llvm::orc::OrcX86_64_Win32::writeResolverCode ( char ResolverWorkingMem,
JITTargetAddress  ResolverTargetAddress,
JITTargetAddress  ReentryFnAddr,
JITTargetAddress  ReentryCtxAddr 

Write the resolver code into the given memory.

The user is responsible for allocating the memory and setting permissions.

ReentryFnAddr should be the address of a function whose signature matches void* (*)(void *TrampolineAddr, void *ReentryCtxAddr). The ReentryCtxAddr argument of writeResolverCode will be passed as the second argument to the function at ReentryFnAddr.
