Yes, that's what you wrote in the code. But the "+ -1" operation gets canonicalized to "- +1" and the constant is changed, which is a valid transformation. This results in two constants being used. This could be fixed with some SH specific RTL pass to look out for +1 and -1 fp constant uses. Not sure if there's a simpler way.
