[PATCH] D69868: Allow "callbr" to return non-void values

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

It seems that callbr (with output) will now be similar to a catchpad. It can set live-in physical register information. (See `test/CodeGen/X86/{seh-catch-all.ll,seh-exception-code.ll,wineh-coreclr.ll,wineh-exceptionpointer.ll}`) Is there any caveat doing this?
