--- Comment #30 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is another reduced testcase:
```
struct t
{
long coef[1];
t(const unsigned long &a) : coef{a} {};
t(const t &a);
};
extern void gen_int_mode(t, int);
struct expand_vec_perm_d {
unsigned char perm[64];
int vmode;
unsigned char nelt;
};
void expand_vec_perm_blend(struct expand_vec_perm_d *d) {
unsigned long mask = 0;
for (unsigned i = 0; i < 4; ++i)
mask |= (d->perm[i] >= 4 ? 3 : 0) << (i * 2);
gen_int_mode(mask, 0);
}
```
The first difference between -g0 vs -g2 starts in curoll where ssa names are
different.
