As mentioned in the preprocessor patches, there's a new kind of preprocessor directive for modules, and it interacts with the compiler-proper, as that has to stream in header-unit macro information (when the directive is an import that names a header-unit). This is that machinery. It's an FSM that inspects the token stream and does the minimal parsing to detect such imports. This ends up being called from the C++ parser's tokenizer and from the -E tokenizer (via a lang hook). The actual module streaming is a stub here. gcc/cp/ * cp-tree.h (module_token_pre, module_token_cdtor) (module_token_lang): Declare. * lex.c: Include langhooks. (struct module_token_filter): New. * cp-tree.h (module_token_pre, module_token_cdtor) (module_token_lang): Define. * module.cc (get_module, preprocess_module, preprocessed_module): Nop stubs.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
