6.3.1 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 c (for C), cp (for C++),
objc (for Objective-C), objcp (for Objective-C++),
and lto (for LTO) 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
- Source files shared between the compiler drivers (such as
gcc) and the compilers proper (such as cc1). If an
architecture defines target hooks shared between those places, it also
has a subdirectory in common/config. See Target Structure.
- Configuration files for supported architectures and operating
systems. See Anatomy of a Target Back End, for
details of the files in this directory.
- Texinfo documentation for GCC, together with automatically generated
man pages and support for converting the installation manual to
HTML. See Documentation.
- 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
- 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.
- The GCC testsuites (except for those for runtime libraries).
