[PATCH] D112429: [ARM] Implement PAC return address signing mechanism for PACBTI-M

[Ties Stuij via Phabricator via llvm-commits]

stuij added a comment.

Unfortunately we're seeing an issue where the shrinkwrap pass isn't aware of PACBTI, and moves the prologue further down the function. Now r12 can already have been used before PAC does.

Of course we'll fix that, however it would be great if someone could review this patch to see if there are other things that need to change.
