--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Full testcase:
int a;
int b(int c, int d)
{
//int c, d;
if (a)
d = b(c, d);
return (1 + c) + d;
}
int b1(int c, int d)
{
// int c, d;
int t = (1 + c);
if (a)
d = b1(c, d);
return t + d;
}
Both of these should have a tail recursion but currently b1 only does.
