[PATCH] D150706: [LAA] Update MaxSafeDepDistBytes when non-unit stride

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

Does this fix a miscompile in loop-vectorize (or elsewhere)?

AFAICT `MaxSafeDepDistBytes` is simply the distance in bytes between dependent accesses and it's not directly the number of elements/iterations that can be performed in parallel without conflict. Loop-vectorize uses `getMaxSafeVectorWidthInBits` to limit the max VF which is the number of elements that can be processed in parallel.
