--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note we don;t optimize at -O1 yet, that is PR 102138.
With this code:
int g(); int h();
int lenzero1(int f, int l) {
if ( len(f, l) == 0)
return g();
return h();
}
We can optimize this one at -O1 since GCC 8 with DOM optimizing it out the
second conditional (I did not look to see what fixed it though).
