It would seem that GCC 4.5.1 is still generating a call to func(), at -Os.
Considering the following reduced test-case:
extern int outcnt;
void test ()
{
outcnt = 0;
if (outcnt == 1) func ();
if (outcnt == 1) func ();
if (outcnt == 1) func ();
if (outcnt == 1) func ();
if (outcnt == 1) func ();
if (outcnt == 1) func ();
if (outcnt == 1) func ();
if (outcnt == 1) func ();
}
