Dear Steve, >From what I can see the failure is for the expand_instantiations script of deal.II, which is compiled as part of deal.II. It uses slightly different flags as the full install, but assuming that you either passed -xHASWELL or -xCORE-AVX2 to CMAKE_CXX_FLAGS it should not generate that code. Before we look into the flags used for compilation, a basic question: Did you start with a clean build directory without any file left over from a more advanced architecture with AVX512 support?
