Hi Vincent,
while I really appreciate your work, I think you're development is going
into the wrong direction here. Those copies you're trying to avoid (not
only with this patch, but also with the previous REG_SEQUENCE patches),
shouldn't happen in the first place. I'm not so deeply into the R
Dot4 now uses 8 scalar operands instead of 2 vectors one which allows register
coalescer to remove some unneeded COPY.
This patch also defines some structures/functions that can be used to handle
every vector instructions (CUBE, Cayman special instructions...) in a similar
fashion.
