[GitHub] [tvm] Lunderberg commented on pull request #12720: [TIR] Implement API for padded layout transformations

Lunderberg commented on PR #12720:

   Looks like the final failing unit test is due to an incorrect mapping in `tir.tensor_intrin.cuda.shared_32x16_to_ldmatrix_32x16_layout`.  It currently returns `[(i % 4) + 4 * (j % 8), 8 * (j // 8) + (i // 16) * 4 + i % 4]`, which doesn't fill all 32x16 indices, and fails when attempted to use `NonSurjectiveInverse` on it.
