[PATCH] D105807: [X86] pr51000 in-register struct return tailcalling

[Nathan Sidwell via Phabricator via llvm-commits]

urnathan updated this revision to Diff 367214.
urnathan retitled this revision from "[X86] pr51000 struct return tailcalling" to "[X86] pr51000 in-register struct return tailcalling".
urnathan added a comment.

Ok, having had a nice long break here's an updated patch.  It addresses the case of tail calling a function that returns a struct in registers.  These are just like tail calling functions that return scalars.

Is it acceptable to have the FIXME comment pointing at pr51000 about the more complicated case when return is via an sret pointer parameter?
