[PATCH] D134982: [X86] Add support for "light" AVX

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

I don’t think -mprefer-vector-width=128 has effect on most instructions. The 256 version was heavily integrated into the type legalization to split operations. I don’t think that was ever done for 128.
