    # Filter known bad flags before applying optimizations
    # 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 either AVX (and AVX2 as a side-effect) or tree
    # vectorization fixes the issue. I am not sure which one is better
    # to disable so below you can choose. Append either of these flags.
