"universe" means all arches, and all kernel configs, so no. The status for head with clang is as follows: - buildworld with default options, e.g. no WITH_XXX or WITHOUT_XXX settings, will complete without any (fatal) warnings. - buildkernel of the default GENERIC config still has one warning left, in sys/dev/mps/mps_sas.c. It should be simple to fix, but I'm checking it with Ken first. - The LINT kernel configs probably have many warnings left. I haven't tested those extensively. As soon as world & kernel compile without warnings, I'd like to have a tinderbox that continually builds with clang. So head won't be regressing any more. :) > ps: are there any plans to add support for compiling kernel+userland with clang > tot? maybe this can be accomplished by doing something like > > echo "WITH_CLANG_TOT=yes" >> /etc/src.conf I'm not working on this at the moment. Pawel Worach (CC'd) has a buildbot setup that builds FreeBSD daily with clang ToT. Apparently just a few patches are needed. > which will turn all -Wformat-invalid-specifier and -Wformat-extra-args errors > into warnings (because clang tot doesn't support -fformat-extensions)? It would be better to push our format extensions upstream, I think. Though the option should probably be renamed to something else, e.g. -ffreebsd-extensions, or such.
