Member Function Documentation

writeResolverCode()

void llvm::orc::OrcX86_64_SysV::writeResolverCode ( char *  ResolverWorkingMem, ExecutorAddr  ResolverTargetAddress, ExecutorAddr  ReentryFnAddr, ExecutorAddr  ReentryCtxAddr  )

static

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.
