--- Comment #3 from Antoine Balestrat antoine.balestrat at gmail dot com ---
I've got a short C testcase if this is of any help.
$ cat fail.c
int a, b, d;
unsigned c;
void f()
{
unsigned q;
for(; a; a++)
if(((c %= d 1) ? : 1) 1)
for(; b; q++);
}
$ xgcc -w -march=native -O2 -fmodulo-sched fail.c
fail.c: In function 'f':
fail.c:10:1: internal compiler error: in maybe_add_or_update_dep_1, at
sched-deps.c:933
}
