[PATCH] D125301: [LoopVectorize] Add option to use active lane mask for loop control flow

[David Sherwood via Phabricator via llvm-commits]

david-arm updated this revision to Diff 434840.
david-arm added a comment.

- Changed name of new enum to PredicationStyle.
- Addressed other refactoring comments.
- Added new test simple_memset_v4i32 to demonstrate that the new style of tail-folding works when choosing a fixed-width VF. This can happen because SVE is enabled, but the cost model may still decide to choose a fixed-width VF.
