I'm not sure that's realistic. Consider e.g. https://bugs.freedesktop.org/show_bug.cgi?id=99078 which is a regression in LLVM 3.9.1 caused by backporting a fix from trunk. Since there are no plans for an LLVM 3.9.2 release, distros have to revert the change in their 3.9.1 packages. Mesa can't tell the difference from the version number, but the generated code can be very different depending on whether the change in question is present or not. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
