    # Override this to indicate what CPU architecture's assembly-language files

    # compatibility, but we strongly recommend overriding this value to
    # improve performance. Turning it off or leaving it turned off is not
    # recommended unless your CPU architecture is unsupported or you are using
    # a tool that does not play nice with assembly language, like Address
    # Sanitizer.
