--- Comment #21 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
int
foo (int x, int y, int a)
{
int i = x;
int j = y;
if (__builtin_expect (x > y, 0))
{
i = a;
j = i;
}
return i * j;
}
shows that even without if IRA does the right job we get the same code as
before.
But the #c20 testcase does (or should have) approx. equal frequencies of the
bbs.
