    # If using -march=native and the CPU supports AVX, launching a d3d9
    # game can cause an Unhandled exception. The cause seems to be the
    # combination of AVX instructions and tree vectorization (implied by O3),
    # all tested archictures from sandybridge to haswell are affected.
    # Disabling AVX (and AVX2 as a side-effect).
    # Since Wine 5.16 AVX is supported. Testing showed 32bit applications
    # crashing with AVX regardless, but 64bit applications worked just fine.
    # So disable AVX only for the 32bit binaries and AVX2 for the 64bit.
