FYI clang devs don't want to take 1 line patch adding another no-op flag upstream. https://lists.llvm.org/pipermail/cfe-dev/2017-July/054588.html

Thanks for trying to push the change upstream. I'm sorry they weren't very receptive of it; your responses were on point and further clarified our intended use case. I'm not sure what Joerg meant by saying "Arch Linux can't do compiler-specific flag definitions". He could be thinking of a regular project that can check for supported compiler flags, but AFAIK that concept is not readily transferable to distro-wide flags. (Even if it was, it would also apply to stack-check and friends so it's a weak argument in my opinion.) At the end of the day, it's not an issue to carry this patch downstream in Arch. :-)
