[Bug rtl-optimization/25629] New: -mcpu=601 doesn't use MQ register

[stef dot simoens at scarlet dot be]

(up to) gcc-3.4.3 -mcpu=601 compiled code uses the MQ register

(at least) gcc-4.0.1 -mcpu=601 compiled code doesn't use MQ any more

tested with:
simple function which calculates remainder

int mod(int a, int b) {
  return a % b;
}

Why is that?
