It is as if you change the source to be:
int g, g2;
int foo(int p, int *gp)
{
int t = 0;
if (p)
t = *gp + 1;
return (*gp + t);
}
--- CUT ---
We get the correct optimization:
foo (p, gp)
{
int prephitmp.9;
int t;
<bb 2>:
if (p != 0)
goto <bb 4>;
else
goto <bb 3>;
<bb 3>:
prephitmp.9 = *gp;
t = 0;
goto <bb 5>;
<bb 4>:
prephitmp.9 = *gp;
t = prephitmp.9 + 1;
<bb 5>:
return prephitmp.9 + t;
}
