+/* Add any extra modes needed to represent the condition code.
+
+   We have a CCNZ mode which is used for implicit comparisons with zero when
+   arithmetic instructions set the condition code.  Only the N and Z flags
+   are valid in this mode, which means that only the =,!= and <,>= operators
+   can be used in conjunction with it.
+
+   We also have a CCCmode which is used by the arithmetic instructions when
+   they explicitly set the C flag (unsigned overflow) and by the bit-test
+   instruction.  Only the =,!= and unsigned <,>= operators can be used in
+   conjunction with it.
+
+   We also have a CCVmode which is used by the arithmetic instructions when
+   they explicitly set the V flag (signed overflow).  Only the =,!= operators
+   can be used in conjunction with it.
+
+   We also have two modes to indicate that the condition code is set by the
+   the floating-point unit.  One for comparisons which generate an exception
+   if the result is unordered (CCFPEmode) and one for comparisons which never
+   generate such an exception (CCFPmode).  */
