In most places, this is just a name change (with the exception of affine.dma_start swapping the operand positions of its tag memref and num_elements operands). Significant code changes occur here: *) Vectorization: LoopAnalysis.cpp, Vectorize.cpp *) Affine Transforms: Transforms/Utils/Utils.cpp PiperOrigin-RevId: 256395088
