; To properly support the matrix intrinsics on, e.g., 32-bit platforms (without
; the need to emit `libc` calls), we perform strided index calculations using
; the same pointer bit-width as the matrix pointers, as determined by the data
; layout. To verify this behaviour, this test runs several strided loads and
; stores through the lowering pass with (32|64)-bit pointers, and verifies the
; generated code extends / truncates strides accordingly. Similarly,
; `data-layout-multiply-fused.ll` adopts this approach to verify the same
; behaviour for index calculations emitted while lowering fused matrix
; multiplies.
