writeIndirectStubsBlock()

void llvm::orc::OrcMips64::writeIndirectStubsBlock ( char * StubsBlockWorkingMem, ExecutorAddr StubsBlockTargetAddress, ExecutorAddr PointersBlockTargetAddress, unsigned NumStubs )

static

Write NumStubs indirect stubs to working memory at StubsBlockWorkingMem.

Stubs will be written as if linked at StubsBlockTargetAddress, with the Nth stub using the Nth pointer in memory starting at PointersBlockTargetAddress.

writeResolverCode()

void llvm::orc::OrcMips64::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.

writeTrampolines()

void llvm::orc::OrcMips64::writeTrampolines ( char * TrampolineBlockWorkingMem, ExecutorAddr TrampolineBlockTargetAddress, ExecutorAddr ResolverFnAddr, unsigned NumTrampolines )

static

Write the requested number of trampolines into the given memory, which must be big enough to hold 1 pointer, plus NumTrampolines trampolines.
