Static Public Member Functions
static LLVM_ABI void writeResolverCode (char *ResolverWorkingMem, ExecutorAddr ResolverTargetAddress, ExecutorAddr ReentryFnAddr, ExecutorAddr ReentryCtxAddr)
Write the resolver code into the given memory.
static LLVM_ABI void writeTrampolines (char *TrampolineBlockWorkingMem, ExecutorAddr TrampolineBlockTargetAddress, ExecutorAddr ResolverAddr, unsigned NumTrampolines)
Write the requested number of trampolines into the given memory, which must be big enough to hold 1 pointer, plus NumTrampolines trampolines.
static LLVM_ABI void writeIndirectStubsBlock (char *StubsBlockWorkingMem, ExecutorAddr StubsBlockTargetAddress, ExecutorAddr PointersBlockTargetAddress, unsigned NumStubs)
Write NumStubs indirect stubs to working memory at StubsBlockWorkingMem.

◆ writeIndirectStubsBlock()

void llvm::orc::OrcI386::writeIndirectStubsBlock ( char * StubsBlockWorkingMem, ExecutorAddr StubsBlockTargetAddress, ExecutorAddr PointersBlockTargetAddress, unsigned NumStubs ) static

◆ writeResolverCode()

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.
