[PATCH] D133486: [LICM] Consider sret as writable object

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Do we use the sret attribute for optimization anywhere else?

Since sret has ABI implications, I'd prefer to use sret specifically for those ABI implications, and use other attributes for any other semantic meaning, if possible.  (Maybe we need some stronger form of "dereferenceable"?)
