[PATCH] D74621: ValueTracking: Fix crash on weird size bswap

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Sure, non-byte multiplies doesn't make sense, but byte multiples generally do. However, after checking LangRef we apparently do require the bitwidth to be a multiple of 16 for this intrinsic: https://llvm.org/docs/LangRef.html#llvm-bswap-intrinsics
