;; We need to be able to move around the values used as condition codes.
;; First spotted as reported in
;; <URL:http://gcc.gnu.org/ml/gcc-bugs/2003-03/msg00008.html> due to
;; changes in loop optimization. The file machmode.def says they're of
;; size 4 QI. Valid bit-patterns correspond to integers -1, 0 and 1, so
;; we treat them as signed entities; see mmix-modes.def. The following
;; expanders should cover all MODE_CC modes, and expand for this pattern.
