--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> 2011-07-07 22:48:48 UTC ---
Note the following is also broken:
int t;
static inline int cvmx_atomic_get32(int *ptr)
{
    return *(volatile int*)ptr;
}
void f(void)
{
  while (!cvmx_atomic_get32(&t))
    ;
}
--- CUT ----
But that is caused by IPA-SRA.
I have a fix for both issues.
