[LLVMdev] Controlling the stack layout

Hi, Nicolas

Look into PrologEpilogInserter.cpp::PEI::runOnMachineFunction(). There
are calls to hooks inside TargetRegisterInfo:
TargetRegisterInfo::processFunctionBeforeCalleeSavedScan() and
TargetRegisterInfo::processFunctionBeforeFrameFinalized().

Maybe they are not so convenient when working via JIT but at least
you'll know the place, where all stack-related stuff is being cooked
:)
