--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.
main0.c:28:20: optimized: applying unroll and jam with factor 2
main0.c:29:24: optimized: loop with 16 iterations completely unrolled (header
execution count 59700049)
main0.c:45:24: optimized: loop vectorized using 16 byte vectors
main0.c:45:24: optimized: loop turned into non-loop; it never loops
main0.c:41:5: optimized: loop with 3 iterations completely unrolled (header
execution count 59700049)
main0.c:44:20: optimized: loop with 16 iterations completely unrolled (header
execution count 0)
-fno-loop-unroll-and-jam fixes it. Can't check trunk right now whether it's
fixed.
