is there any way without resorting to machine code to generate
the (intel-named)
MOVDQ (AX), X0 // move 16-bytes into X0
by the way, it's easy to get the upper double-quad of X0 from acid
acid: *X0+8\Y
(groans from the back?) probablly not. you already knew that.

/sys/doc/asm.ms
Some instructions use
.CW O
(`octword') for 128-bit values, where the processor handbook
variously uses
.CW O
or
.CW DQ .
The assembler also consistently uses
.CW PL
for `packed long' in
XMM instructions, instead of
.CW Q ,
.CW DQ
or
.CW PI .
MOVO seems to be available.
