--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
s390x excessive unrolling params?
make check-gcc
RUNTESTFLAGS="--target_board=unix/--param=max-completely-peel-times=64
dg-torture.exp=pr117567.c"
reproduces this on x86_64 as well.
The testcase looks broken at runtime (but it's dg-do compile), it does
indeed access a[-63].
Adding -w to additional options should "fix" it.
