[PATCH] D156716: [AArch64][PAC] Check authenticated LR value during tail call

[Momchil Velikov via Phabricator via llvm-commits]

chill added inline comments.


================
Comment at: llvm/lib/Target/AArch64/AArch64PointerAuth.cpp:256
+
+  // FIXME If FEAT_FPAC is implemented by the CPU, this check can be skipped.
+
----------------
nit: The check for `FEAT_FPAC` perhaps can be done in `getAuthenticatedLRCheckMethod` (and possibly return `None`), so the logic of deciding whether to emit code or not is kept in one place.
