16 cxref-cpp - A modified C preprocessor to use with cxref.
24 To improve the output that is available a modified version of the GNU CPP V2.7.2
25 is supplied (named cxref-cpp).
27 This modified C preprocessor allows for a finer control over some features of
28 the preprocessing that are not important for a compiler. In a standard
29 preprocessor, the preprocessor directives are intended for use only by the
30 preprocessor, so passing the information through is not important.
32 With cxref-cpp, there are two features that are different to the standard GNU
36 The #include directives from the file are output in the same way as the #defines
37 are output. An extra flag has been added to cpp to do this, '-dI', it works in
38 the same way as the existing '-dD' flag for #defines.
40 Comments trailing a #include or a #define are dropped with GNU CPP even if -C is
41 used. This is not important while compiling, but is useful for documenting.
46 The same as for gcc, apart from '-dI' described above.
