[Bug c/45468] gcc does not warn about missing `-O' flag when specifying `-Wuninitialized'

[pinskia at gcc dot gnu dot org]

------- Comment #4 from pinskia at gcc dot gnu dot org  2010-08-31 20:28 -------
#include <stdio.h>

int main(void)
{
    int i;
    printf ("%d\n", i);

    return 0;
}

Is warned about with -Wuninitialized at -O0.  We don't warn about the uses that
might be used unitialized.  That means if i is gets put into a PHI before the
use, we don't warn.
