+/* Like other non-CC0 ports, MMIX need to code which combination of
+   comparison insn and branch insn or conditional-set insn to use into the
+   condition mode.  The CC mode depends partly on which condition is used
+   and partly on the type of the operands.  */
+
+/* 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.  */
 CC (CC_UNS)
+
+/* The CC_FP mode is for an non-equality floating-point comparison, using
+   the FCMP or FCMPE insn.  The result is (integer) -1 or 1 for

 CC (CC_FP)
+
+/* The CC_FPEQ mode is for an equality floating-point comparison, using

 CC (CC_FPEQ)
+
+/* The CC_FUN mode is for an ordering comparison, using the FUN or FUNE
