I've triaged the following regressions to be introduced at revision r154688:
FAIL: gcc.c-torture/execute/arith-rand-ll.c execution, -O3
-fomit-frame-pointer -funroll-loops
FAIL: gcc.c-torture/execute/arith-rand-ll.c execution, -O3
-fomit-frame-pointer -funroll-all-loops -finline-functions
FAIL: gcc.c-torture/execute/arith-rand.c execution, -O3 -fomit-frame-pointer
-funroll-loops
FAIL: gcc.c-torture/execute/arith-rand.c execution, -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions
Looking through other reports, that revision (including follow-ups) exposed
latent bugs in other ports, so it's not unlikely the case here as well.
Still, I think it's reasonable to CC the author of that revision and marking
this PR as middle-end, at least until I've looked closer.
