79
This manual documents the internals of the GNU compilers, including
80
how to port them to new targets and some information about how to
81
write front ends for new languages.  It corresponds to the compilers
82
@ifset VERSION_PACKAGE
83
@value{VERSION_PACKAGE}
84
@end ifset
85
version @value{version-GCC}.  The use of the GNU compilers is documented in a
86
separate manual.  @xref{Top,, Introduction, gcc, Using the GNU
87
Compiler Collection (GCC)}.
88
 
89
This manual is mainly a reference manual rather than a tutorial.  It
90
discusses how to contribute to GCC (@pxref{Contributing}), the
91
characteristics of the machines supported by GCC as hosts and targets
92
(@pxref{Portability}), how GCC relates to the ABIs on such systems
93
(@pxref{Interface}), and the characteristics of the languages for
94
which GCC front ends are written (@pxref{Languages}).  It then
95
describes the GCC source tree structure and build system, some of the
96
interfaces to GCC front ends, and how support for a target system is
97
implemented in GCC@.
98

GCC's command line options are indexed here without any initial @samp{-}
182
or @samp{--}.  Where an option has both positive and negative forms
183
(such as @option{-f@var{option}} and @option{-fno-@var{option}}),
184
relevant entries in the manual are indexed under the most appropriate
185
form; it may sometimes be useful to look up both forms.
