Ahmed Taei 499e89fc91 Add patterns to lower vector.multi_reduction into a sequence of vector.reduction ... Three patterns are added to convert into vector.multi_reduction into a sequence of vector.reduction as the following: - Transpose the inputs so inner most dimensions are always reduction. - Reduce rank of vector.multi_reduction into 2d with inner most reduction dim (get the 2d canical form) - 2D canonical form is converted into a sequence of vector.reduction. There are two things we might worth in a follow up diff: - An scf.for (maybe optionally) around vector.reduction instead of unrolling it. - Breakdown the vector.reduction into a sequence of vector.reduction (e.g tree-based reduction) instead of relying on how downstream dialects handle it. Note: this will requires passing target-vector-length Differential Revision: https://reviews.llvm.org/D101570		2021-04-30 10:52:21 -07:00
