--- Comment #1 from Gabriel Ravier <gabravier at gmail dot com> ---
For some reason, I can reproduce this, but only if `-mavx2` is not present.
Having AVX2 enabled somehow ends up makes it so this is optimized to a `return
~x`.

(Also, this means that it is a bitwise not and not a negate that this should
optimize down to)
