URL: https://github.com/llvm/llvm-project/commit/1f729e0bc7a7012fa3a7618100f0865e4e32fc0d DIFF: https://github.com/llvm/llvm-project/commit/1f729e0bc7a7012fa3a7618100f0865e4e32fc0d.diff LOG: [LV] Reverse mask up front, not when creating vector pointer. Reverse mask early on when populating BlockInMask. This will enable separating mask management and address computation from the memory recipes in the future and is also needed to enable explicit unrolling in VPlan.
