[PATCH] D70635: Reland [AArch64][MachineOutliner] Return address signing for outlined functions

[Scott Linder via Phabricator via llvm-commits]

scott.linder added inline comments.


================
Comment at: llvm/lib/Target/AArch64/AArch64InstrInfo.cpp:5649
 
   unsigned LastInstrOpcode = RepeatedSequenceLocs[0].back()->getOpcode();
 
----------------
You may already be aware, but there is a container-overflow here in the ASan build (see http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-fast/builds/37147/steps/check-llvm%20asan/logs/stdio for the failure). Seems like `RepeatedSequenceLocs` can be empty here.
