; /* We isolate a set of partial tile prefixes, which contains only partial
; tile prefixes that have exactly Mr x Nr iterations of the two innermost
; loops produced by the optimization of the matrix multiplication. Mr and
; Nr are parameters of the micro-kernel (see getMicroKernelParams and
; getMacroKernelParams from lib/Transform/ScheduleOptimizer.cpp for
; details). This test check that in case it cannot be proved that
; the number of loop iterations can be evenly divided by tile sizes
; and we tile and unroll the point loops, it helps to get rid of
; the conditional expressions of the unrolled innermost loops, which
; prevents stores and loads of the unrolled loops from being sunk
; and hoisted. Otherwise, it causes a run-time regression in comparison
; to the vectorized code with sunk and hoisted memory accesses. */
