+/* Like other non-CC0 ports, MMIX need to code which combination of

+/* The "usual" CC mode is used for a signed operands integer comparison,
+ where the CMP insn is used and the result is (integer) -1, 0 or 1 for
+ respectively a < b, a == b and a > b. */

+/* The CC_UNS mode is for an unsigned operands integer comparison using
+ the CMPU insn. Result values correspond to those in CCmode. */
