[PATCH] D105807: [X86] pr51000 struct return tailcalling

[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: llvm/test/CodeGen/X86/sibcall.ll:854
   %b = call fastcc %struct.foo* @ret_struct()
   tail call fastcc void @t21_f_sret2(%struct.foo* noalias sret(%struct.foo) %a, %struct.foo* noalias %b) nounwind
   ret void
----------------
Oh, now I remember what happened the last time someone tried to fix this... t21_sret_to_sret_structs_mismatch() is also illegal to transform, for similar reasons to t21_sret_to_non_sret().
