[Bug target/37488] register allocation spills floats needlessly

[bonzini at gnu dot org]

------- Comment #3 from bonzini at gnu dot org  2009-02-04 16:03 -------
requires computed gotos and floats, even smaller testcase

void test(char *ip, double *reg_f)
{
  static void * const addrs[] = {&&L1, &&L2};
  double reg_f_a;

  reg_f_a = 0.0;
  goto *addrs[*++ip];

L1: reg_f_a = reg_f[*++ip];
L2: reg_f[0] = reg_f_a;
}
