Subdirectories of gcc

The gcc directory contains the following subdirectories:

language

Subdirectories for various languages. Directories containing a file config-lang.in are language subdirectories. The contents of the subdirectories cp (for C++) and objc (for Objective-C) are documented in this manual (see Passes and Files of the Compiler); those for other languages are not. See Anatomy of a Language Front End, for details of the files in these directories.

config

Configuration files for supported architectures and operating systems. See Anatomy of a Target Back End, for details of the files in thie directory.

doc

Texinfo documentation for GCC, together with automatically generated man pages and support for converting the installation manual to HTML. See Documentation.

fixinc

The support for fixing system headers to work with GCC. See fixinc/README for more information. The headers fixed by this mechanism are installed in libsubdir/include. Along with those headers, README-fixinc is also installed, as libsubdir/include/README.

ginclude

System headers installed by GCC, mainly those required by the C standard of freestanding implementations. See Headers Installed by GCC, for details of when these and other headers are installed.

intl

GNU libintl, from GNU gettext, for systems which do not include it in libc. Properly, this directory should be at top level, parallel to the gcc directory.

po

Message catalogs with translations of messages produced by GCC into various languages, language.po. This directory also contains gcc.pot, the template for these message catalogues, exgettext, a wrapper around gettext to extract the messages from the GCC sources and create gcc.pot, which is run by make gcc.pot, and EXCLUDES, a list of files from which messages should not be extracted.

testsuite

The GCC test suites (except for those for runtime libraries). See Test Suites.
