> @aaron.ballman's point that maybe this should be -Werror by default in clang sounds plausible - because not all projects will be using -Werror, etc. If that helps some users who work on LLVM itself but don't want to turn on -Werror (not sure why - the buildbots will do it and so things will break/you'll have to fix stuff if you're not building with -Werror using a fairly recent clang) that's OK.

thanks, I'll open a diff to make `return-type` and error by default and see how that goes.
