Walter, looks like you have the src/dst register mod/rm selection swapped for the movq2dq instruction:

    movq2dq XMM4, MM0;



assembles thusly:



    movq2dq XMM0, MM4



This is probably the first time anyone has tried to use this instruction with your compilers.  ;)

I have it in my test suite, I'll check it again. -Walter
