That's not really a fair assessment. By far the most important thing in Fedora that needs llvm is Mesa. The llvm build system has a fairly comprehensive test suite (which, btw, fails on at least arm with 3.6.1, but passes on all arches with 3.7), and Mesa has another test suite in the form of piglit that we can use to ensure that changing llvm doesn't regress llvmpipe or r600 or radeonsi. So we can in fact be pretty confident that llvm upgrades won't break the things we actually use llvm for in Fedora. - ajax -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
