--- Comment #1 from Walter Bright <bugzilla@digitalmars.com> ---
The MOVDQU instruction is:

    F3 0F 6F /r MOVDQU xmm1, xmm2/m128

    Move unaligned packed integer values from xmm2/m128 to xmm1.

--- Comment #2 from Walter Bright <bugzilla@digitalmars.com> ---
What's happening is in iasm.d the operand size is encoded into 5 bit flags, and there isn't room for another _128 bit, so the assembler just accepts any size.

The solution is to refactor the way operand sizes are encoded to accept more values.
