[PATCH] D75815: [InstCombine] Simplify calls with "returned" attribute

[Johannes Doerfert via Phabricator via llvm-commits]

jdoerfert added a comment.

I would really prefer not to overload existing attributes but instead introduce a new one or reuse existing ones them with their "current meaning" (e.g., `optnone`). I'm also against "complex" attributes when they are comprised of orthogonal parts we can split off, e.g., something like `nosanitize` should not imply `noipa`. That said, I think having `noipa` seems reasonable.
