C++ Module keywords
This adds the module keywords. These are special internal tokens
generated by the preprocessor's module-control-line token peeking
logic. Spelling them with a space means that they turn back into
regular tokens in preprocessor output (but do skew the column
numbering :()
gcc/c-family/
* c-common.c (module, import, export): New internal tokens (with
trailing space).
* c-common.h (RID__MODULE, RID__IMPORT & RID__EXPORT): Enumerate
them.
(D_CXX_MODULES, D_CXX_MODULES_FLAGS): Enable them.
* c-cppbuiltin.c (c_cpp_builtins): Feature macro.
gcc/cp/
* lex.c (init_reswords): Maybe enable module keywords.
