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;
