Description
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.
Our users have reported this occurs on: r600 driver nvidia gfx card AMD Athlon II X4 620 AMD Phenom II x4 N930 Intel Quad 9650 Intel i3 530
