--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note really the loops at -O3 should really be optimized to:
void f3(int x, int y)
{
int t;
g(0);
for (t = 1; t < 50; t++)
{
g(1);
}
}
That is peel off the first iteration. I don't know why -O3 -fno-ssa-phiopt
-fno-tree-vrp does not do that either. I will file that as a different bug
because this is about converting the comparison only in COND_EXPR gimple.
