Re: A89: matrix
you push all regs on stack first, since you destroy them, and it is nice to be
able to get them back :)
you could though save a7 (or all) to a fixed data-area in your program.
the pushes of the regs is to be considered in this method too, so you only gain
when you exceed a certain number of bytes too move.. I havn't calculated how
many yet though, maybe it isn't much.
