NAME

cxref-cpp - A modified C preprocessor to use with cxref.

SYNOPSIS

cxref-cpp ...

DESCRIPTION

To improve the output that is available a modified version of the GNU CPP V2.7.2 is supplied (named cxref-cpp).

This modified C preprocessor allows for a finer control over some features of the preprocessing that are not important for a compiler. In a standard preprocessor, the preprocessor directives are intended for use only by the preprocessor, so passing the information through is not important.

With cxref-cpp, there are two features that are different to the standard GNU CPP:

: The #include directives from the file are output in the same way as the #defines are output. An extra flag has been added to cpp to do this, '-dI', it works in the same way as the existing '-dD' flag for #defines.
: Comments trailing a #include or a #define are dropped with GNU CPP even if -C is used. This is not important while compiling, but is useful for documenting.

OPTIONS

The same as for gcc, apart from '-dI' described above.
