[PATCH] D112326: [AArch64] Async unwind - do not schedule frame setup/destroy

[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: llvm/lib/Target/AArch64/AArch64InstrInfo.cpp:1113
+          TFI.hasFP(MF) && MI.modifiesRegister(AArch64::FP) &&
+          MF.getFunction().needsUnwindTableEntry());
 }
----------------
Not sure I understand the logic here.  Can we just make CFI directives a scheduling barrier, like we do for SEH directives?  Why are instructions that modify the frame pointer special?
