according to AMD Volume 4,

Quote:

movd xmm, reg/mem64 ; 66 0F 6E /r


Razz

but when I try:

Quote:

use64
movd xmm0, rax


Smile

I get error:

Quote:

error: invalid size of operand.


Confused


the above movd zero extends rax to 128 bits in xmm0,
not sure what size the operand is then, 128 bits? 64 bits? Sad

I tried also:

Quote:

use64
movd qword xmm0, rax
movd xmm0, dqword rax


both of which dont function. Mad
