Code:

use64
movq xmm0,[rcx]
movq xmm0,[Label]
movq xmm0,qword[rcx]
movq xmm0,qword[Label]

Operand sizes do not match error.

Code:

movq xmm0,xmm1

compiles without error

Opcode: F3 0F 7E /r
MOVQ xmm1,xmm2/mem64
From AMD SIMD documentation

So its 1 of 2 things:
-in 64bit mode you can't use addressing for 2nd operand in movq
-bug in compiler 1.67.8

erm, try using 1.67.11 or something Very Happy

and read the whatsnew...
...ok I'll do it myself:

Code:

version 1.67.9 (Sep 21, 2006)

[+] Added some Win64 headers and examples in the Windows package.

[-] Fixed another operand size checking bug with MOVQ instruction.

Works for me, I assumed I was using the newest version. Had I checked this thread wouldn't have been necessary.
