描述

In the context of Issue-115849 , I see that affine transformation is producing invalid IR like below where vector is being stored to a memref of size 1x1xf32.

affine.vector_store %5, %alloc[0, 0] : memref<1x1xf32>, vector<64x64xf32>

%6 = affine.vector_load %alloc[0, 0] : memref<1x1xf32>, vector<64x512xf32>

I think validity of the affine transformations need to be enhanced by introducing good verifiers.
