[mlir][vector] Add ApplyMultiReductionPatternsOp by amd-eochoalo · Pull Request #183846 · llvm/llvm-project

amd-eochoalo · 2026-02-27T21:52:07Z

Almost a revert of #182332.

Effectively it is a change of name from ApplyLowerMultiReductionPatternsOp (which existed before #182332) to ApplyMultiReductionPatternsOp. This is change of name serve as a disambiguation as we will add a new lowering method that is separate from unrolling, flattening, and reorder_and_expand.

@banach-space this PR corresponds to this comment here

ApplyLowerMultiReductionPatternsOp -> ApplyMultiReductionPatternsOp. This is an umbrella Op rather than just "lowering" (provided that we are OK with the notation that "unrolling" != "lowering").
