--- Comment #17 from H. Peter Anvin <hpa at zytor dot com> --- So I am still confused by this. It would seem that this really ought to be a very simple request, and that adding compiler support for all these cases would impose a really large burden on the gcc team (you guys!), *plus* that we would have to have a very long pipeline for compiler support. As I have said, the code that I have put here is only an example. I have some instances of code which involved a thousand lines of assembly, which I ended up having to throw out (and not be able to use that functionality) exactly because doing it without macros ended up being too painful. Using -Wa,-include,... sort of works, but it requires that either the Makefile system knows *a priori* which files will need to use this (and this will largely be based on #include files - which make doesn't know about until after the first run) or alternatively ALL files need to be rebuilt when one of these headers change -- which is impractical in the extreme. The kernel is shock full of examples of these things, and it does not seem fair to expect you to handle all of our strange requirements. If you *do* want me to submit tickets even for some of the most heavily used constructs, I would be happy to do so, though.
