-@defmac EXTRA_CC_MODES
-Condition codes are represented in registers by machine modes of class
-@code{MODE_CC}. By default, there is just one mode, @code{CCmode}, with
-this class. If you need more such modes, create a file named
-@file{@var{machine}-modes.def} in your @file{config/@var{machine}}
-directory (@pxref{Back End, , Anatomy of a Target Back End}), containing
-a list of these modes. Each entry in the list should be a call to the
-macro @code{CC}. This macro takes one argument, which is the name of
-the mode: it should begin with @samp{CC}. Do not put quotation marks
-around the name, or include the trailing @samp{mode}; these are
-automatically added. There should not be anything else in the file
-except comments.
-
-A sample @file{@var{machine}-modes.def} file might look like this:
-
-@smallexample
-CC (CC_NOOV) /* @r{Comparison only valid if there was no overflow.} */
-CC (CCFP) /* @r{Floating point comparison that cannot trap.} */
-CC (CCFPE) /* @r{Floating point comparison that may trap.} */
-@end smallexample
-
-When you create this file, the macro @code{EXTRA_CC_MODES} is
-automatically defined by @command{configure}, with value @samp{1}.
