Note that while RX has one mode for floating-point, it has two other modes to deal with instructions that fail to set all of the flags (or fails to set the flags in a way that is useful for the comparison). Depending on how regular your instructions are, you may find that CCmode is not enough to eliminate all comparisons. It is, however, a good start. r~
