+/* Add any extra modes needed to represent the condition code.
+
+   For the i386, we need separate modes when floating-point
+   equality comparisons are being done.
+
+   Add CCNO to indicate comparisons against zero that requires
+   Overflow flag to be unset.  Sign bit test is used instead and
+   thus can be used to form "a&b>0" type of tests.
+
+   Add CCGC to indicate comparisons agains zero that allows
+   unspecified garbage in the Carry flag.  This mode is used
+   by inc/dec instructions.
+
+   Add CCGOC to indicate comparisons agains zero that allows
+   unspecified garbage in the Carry and Overflow flag. This
+   mode is used to simulate comparisons of (a-b) and (a+b)
+   against zero using sub/cmp/add operations.
+
+   Add CCZ to indicate that only the Zero flag is valid.  */
