So if i want to store xmm0 register :
label(storexmm0)
moss [storexmm0],xmm0
storexmm0:
dd 00000000
it's not enough ?
have to do a movq with dd 00000000 00000000 00000000 00000000 ?

if you meant the packed xmm register, then you can use MOVDQA.

you may want to use movdqu instead of movdqa if the memory is not aligned.
