"Oh, crap"

I hope I can stick with my cmp/jmp model and manage them myself still,
though, because there's a LOT of patterns in m32c where the set of
flags affected depends on which alternative you select, and most
patterns affect the flags in some (usually nonorthagonal) way.

Or is gcc going to start putting things between the cmp and jmp?
