--- Comment #19 from Richard Biener <rguenth at gcc dot gnu.org> ---
GCC does unroll the loop nest in the testcase. I checked GCC 14 with -O2
-fopt-info:
...
t.C:28:27: optimized: loop with 2 iterations completely unrolled (header
execution count 268435458)
t.C:27:23: optimized: loop with 2 iterations completely unrolled (header
execution count 89478486)
...
so the reported issue is fixed. We're also good enough to elide the whole
benchmark (but that's besides the point).
