[Mesa-dev] [Bug 109259] Mesa compiled with LLVM/clang-7.0 segfaults
https://bugs.freedesktop.org/show_bug.cgi?id=109259 --- Comment #3 from Dylan Baker --- I'm confused, you're targeting generic x86_64, but compiling with -mavx and -mavx2? Additionally, there's a bug with SWR (I can't find it right now), due to global constructors that mean that if you build SWR you have to have the special instructions it relies on. -- You are receiving this mail because: You are the QA Contact for the bug.

[Mesa-dev] [Bug 109259] Mesa compiled with LLVM/clang-7.0 segfaults
https://bugs.freedesktop.org/show_bug.cgi?id=109259 Bug ID: 109259 Summary: Mesa compiled with LLVM/clang-7.0 segfaults Product: Mesa Version: 18.3 Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Mesa core Assignee: mesa-dev@lists.freedesktop.org Reporter: tpg...@gmail.com QA Contact: mesa-dev@lists.freedesktop.org Hi, we have noticed that mesa-18.3.x segfault when it is compiled with LLVM/clang-7.0.x and run on older hardware. After some deep digging we noticed this may be related to missing AVX instructions on these machines, even if we build for generic x86_64, i686 targets. Fast workaround for eliminating segfaults was to build Mesa with gcc :( https://github.com/OpenMandrivaAssociation/mesa/commit/4d330587a4d80012c5888e1a33a01a7a979b84e8 Rebuilding Mesa with LLVM/clang-7.0.1 still segfaults.
