preprocessor: main-file cleanup
Thu Nov 19 12:46:50 GMT 2020
In preparing module patch 7 I realized there was a cleanup I could
make to simplify it. This is that cleanup. Also, when doing the
cleanup I noticed some macros had been turned into inline functions,
but not renamed to the preprocessors internal namespace
(_cpp_$INTERNAL rather than cpp_$USER). Thus, this renames those
functions, deletes an internal field of the file structure, and
determines whether we're in the main file by comparing to
pfile->main_file, the _cpp_file of the main file.
* internal.h (cpp_in_system_header): Rename to ...
(_cpp_in_system_header): ... here.
(cpp_in_primary_file): Rename to ...
(_cpp_in_main_source_file): ... here. Compare main_file equality
and check main_search value.
* lex.c (maybe_va_opt_error, _cpp_lex_direct): Adjust for rename.
* macro.c (_cpp_builtin_macro_text): Likewise.
* directives.c (do_include_next): Likewise.
(do_pragma_once, do_pragma_system_header): Likewise.
* files.c (struct _cpp_file): Delete main_file field.
(pch_open): Check pfile->main_file equality.
(make_cpp_file): Drop cpp_reader parm, don't set main_file.
(_cpp_stack_file): Check pfile->main_file equality.
(struct report_missing_guard_data): Add cpp_reader field.
(report_missing_guard): Check pfile->main_file equality.
