GNU Compiler Collection (GCC) Internals
5.3.1 Subdirectories of `gcc'
The `gcc' directory contains the following subdirectories:
- 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 section Passes and Files of the Compiler); those for other languages are not.
See section Anatomy of a Language Front End, for details of
the files in these directories.
- Configuration files for supported architectures and operating
systems. See section Anatomy of a Target Back End, for
details of the files in thie directory.
- Texinfo documentation for GCC, together with automatically generated
man pages and support for converting the installation manual to
HTML. See section 5.3.7 Building Documentation.
- 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
- System headers installed by GCC, mainly those required by the C
standard of freestanding implementations. See section Headers Installed by GCC, for details of when these and other headers are
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.
- 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
make gcc.pot, and `EXCLUDES', a list of files from
which messages should not be extracted.
- The GCC test suites (except for those for runtime libraries).
See section 5.4 Test Suites.
