[PATCH] D70174: [AArch64][SVE] Use FP for scavenging slot

[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: llvm/lib/Target/AArch64/AArch64RegisterInfo.cpp:327
   const AArch64FrameLowering &TFI = *getFrameLowering(MF);
-  return TFI.hasFP(MF);
+  return TFI.hasFP(MF) && !TFI.estimateSVEStackObjectOffsets(MF.getFrameInfo());
 }
----------------
The problem here, I guess, is the spill slot can't be addressed relative to SP? That makes sense, I guess... but do we also need to check for stack realignment here?
