I also built GCC itself with -O3 (and -mcpu=ultrasparc3
-mtune=ultrasparc3); not yet sure whether that matters.
I rebuilt GCC with CFLAGS="-O3 -mcpu=niagara2 -mtune=niagara2".
And ... tada! It breaks when building GAP:
{{{
../../src/blister.c: In function 'InitKernel':
../../src/blister.c:2743:1: internal compiler error: in
simplify_immed_subreg, at simplify-rtx.c:5262
}}}
Exactly.
three times.
No problems with the same GCC built with CFLAGS="-O3 -mcpu=niagara2
-mtune=niagara2" if I build GAP with CFLAGS="-O2".
Yep. Although I didn't get them with GCC 4.7.0 and '-mcpu=...
-mtune=... -O3', so this might be a regression in 4.7.1 or 4.7.2.
Did you search GCC bugzilla? (I haven't yet.)
