[Bug target/37668] New: Obvious bug in arm.c: arm_size_rtx_costs() case NEG:

["martinwguy at yahoo dot it" <gcc-bugzilla at gcc dot gnu dot org>]

Hi
  I spotted this while trawling through the arm code generator: the code in the
NEG case has no effect. I assume the NEG case should return if the condition
matches; patch attached. It's still present in trunk.

    case NEG:
      if (TARGET_HARD_FLOAT && GET_MODE_CLASS (mode) == MODE_FLOAT)
        *total = COSTS_N_INSNS (1);
      /* Fall through */
    case NOT:
      *total = COSTS_N_INSNS (ARM_NUM_REGS (mode));
      return false;
