[Bug rtl-optimization/36758] [4.3/4.4 Regression] addition moved out of the loop when used with an argument

[pinskia at gcc dot gnu dot org]

------- Comment #11 from pinskia at gcc dot gnu dot org  2008-09-21 00:45 -------
Here is another testcase which shows the issue:
int f(int b);

float g(int a)
{
  while (f(a + 1));
  while (f(a));
}
--- CUT ---
This increases the need for another volatile register and in fact increases
register pressure even more.
