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.
