--- Comment #2 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
In the future please show us what -march=native expands to.

markus@x4 tmp % cat bug295.i
unsigned short a;
int b, c;
int *d;
void fn1() {
  *d = 24;
  for (; *d <= 65;) {
    unsigned short *e = &a;
    b = (a &= 0 <= 0) < (c ?: (*e %= *d));
    for (; *d <= 83;)
      ;
  }
}

markus@x4 tmp % gcc -c -O3 -march=amdfam10 bug295.i
