[PATCH] D89170: [AMDGPU] Select flat scratch instructions where available

[Sebastian Neubauer via Phabricator via llvm-commits]

Flakebi added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIFrameLowering.cpp:482
 
   if (MFI->hasFlatScratchInit()) {
     emitEntryFunctionFlatScratchInit(MF, MBB, I, DL, ScratchWaveOffsetReg);
----------------
Should this be `MFI->hasFlatScratchInit() || (ST.enableFlatScratch() && requiresStackPointerReference(MF))`?
Otherwise, the scratch does not get initialized (I guess it’s fine to do that in a later patch).
