That's what I am afraid of. Even if we manage to compile everything, there is no guarantee that the code will work. I suggest to simply disable libsanitizer build on the older systems which is what happens de facto now. If there is significant interest in maintaining asan&co on older systems (which I have not seen so far), then those interested will need to help us in upstream repository (llvm) by a) sending us patches using http://llvm.org/docs/Phabricator.html and b) setting up a public buildbot (attached to the LLVM master bot) with the system they care about. If there is no one interested enough to do a) and b) I say we should not spend time on this. And this discussion does not affect the merge since nothing that works today will get broken, right? > > I think the main problem is that you are mixing standard glibc headers and > linux kernel headers in the same source file, that is a big no no. > Lots of the kernel headers declare the same things as glibc headers. > > I'd strongly recommend splitting the files, so that you include absolute > minimum of > glibc headers when you include linux/* and/or asm/* headers and no kernel > headers > if you include tons of glibc headers. > And as the errors show up, there are also .cfi* directives that are used > unconditionally (you've set you've removed it from sanitizer_common or where > it > was used (IMHO a pitty, much better would be conditionalizing them on either > compiler > preprocessor macros or whatever clang provides as alternative for that when > not building > with gcc)), but they are used in tsan (in HACKY_CALL macro).
