--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> ---
Thanks for the fix, I've got one another test-case that started to ICE since
the affected revision:
$ cat ice.i
int c;
unsigned char d;
int e (unsigned char *f)
{
int g;
for (int a; a; a++)
{
for (int b = 0; b < 6; b++)
g += __builtin_abs (f[b] - d);
f += c;
}
return g;
}
$ gcc -ftrapv -Ofast ice.i
during GIMPLE pass: vect
ice.i: In function ‘e’:
ice.i:3:5: internal compiler error: in vectorize_fold_left_reduction, at
tree-vect-loop.c:6217
