    • PR preprocessor/60723 - missing system-ness marks for macro tokens · a0bc2268 
      When a system macro is expanded in a non-system file during
out-of-line preprocessing, it can happen that the preprocessor forgets
to emit line markers to express the system-ness status of tokens that
come after the expansion of the macro.

That can lead to situations where the entire non-system file can be
considered as being a system file and thus have its warnings be
discarded during the compilation of the resulting preprocessed file.

My understanding is that this is due to the preprocessor not
systematically detecting (and reporting) the change in system-ness of
tokens.

And this is what this patch does.  Each time the system-ness of a
given token is different from the previous token that was emitted by
the preprocessor, it emits a line marker for the sole purpose of
marking the new system-ness of the subsequent tokens to come.

Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk.

gcc/c-family/ChangeLog:
	* c-ppoutput.c (struct print::prev_was_system_token): New data
	member.
	(init_pp_output): Initialize it.
	(maybe_print_line_1, maybe_print_line, print_line_1, print_line)
	(do_line_change): Return a flag saying if a line marker was
	emitted or not.
	(scan_translation_unit): Detect if the system-ness of the token we
	are about to emit is different from the one of the previously
	emitted token.  If so, emit a line marker.  Avoid emitting
	useless adjacent line markers.
	(scan_translation_unit_directives_only): Adjust.

gcc/testsuite/ChangeLog:
	* gcc.dg/cpp/syshdr{4,5}.{c,h}: New test files.
