Sorry. For amd there is 128 bytes of space beyond the end of the
stack that is free to use if there are no calls, at least in linux,
of which not all 128 bytes are used. It looks like some of the
other primitives also use this space. Is there another primitive
that allocates space that I can use as an example?<br>
