[PATCH] D42600: [CodeGen][Shrink-wrap]split restore point

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

It looks like for 32-bit ARM, shrink-wrapping is blocking the formation of `pop {pc}` instructions to return from a function (so we instead `pop {lr}; bx lr`).  Is this new, or a side-effect of shrink-wrapping more cases?  Any idea what's causing it?  Is there an issue tracking it?
