[PATCH] D83741: [libunwind] Fix CIE v1 return address parsing

[Ryan Prichard via Phabricator via llvm-commits]

rprichard added a comment.

For reference, here's where Clang selects the CIE version:

And here's where Clang emits the return address register:

LLVM has another CIE parser (for dumping tools, I think):
