[PATCH] D53554: [Argument Promotion] Only promote args when function attributes are compatible

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

I'm also seeing issues from ArgumentPromotion with my min-legal-vector-width attribute used by X86 with avx512 enabled and -mprefer-vector-width=256. I think I'll need to override the X86 implementation of areFunctionArgsABICompatible to check for this attribute as well.
