It should be "movd xmm3,r9d". If you want to move the qword, use "movq xmm3,r9".

This's actually the opcode for "movq mm3,r9". At first I thought that the correct opcode should be 49 66 0f 6e d9 but I was wrong  . Masm-generated opcode is 66 49 0f 6e d9 (REX must follow the legacy prefix). This is also the same as the disassembled result of Windbg. |

I had this strange feeling that I've been already fixing this. Anyway, it's fixed in 1.65.25.
I'm planning it to be the last release before the 1.66 milestone. So if you've got some more bug reports, please hurry.  |

[bug?]Operand size checking with LEA
Is it correct that lea should check the operand size? I think it might be a bug. Code: a rd 1 b rw 1 lea ax,[bx+b-a] ;<-- Error: operand sizes do not match |
