--- Comment #11 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Thinking about this some more, this is a not a hoisting problem but a sinking
problem.
basically we have:
int f(void);
int h(void);
int g(int a)
{
if (a)
return f() + 10;
return h() + 10;
}
Which should be converted into:
int g1(int a)
{
int t;
if (a)
t = f();
else
t = h();
return t + 10;
}
We handle hoisting just fine; just not sinking common.
So we don't need reassoc in the original testcase if we do sinking.
