writeIndirectStubsBlock()

void llvm::orc::OrcX86_64_Base::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.

static

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