The MOVQ instruction moves a 64-bit data value from one MMX register to another
MMX register or memory, or it moves the 64-bit data from one MMX register or
memory to another MMX register. Copying data from one memory location to another
memory location cannot be accomplished with the MOVQ instruction.

The emulate MMX instruction bit (EM) of the control register (CR0) is set to 1.
Save the floating-point or MMX state if the task switch bit (TS) of the control
register (CR0) is set to 1.
During instruction execution, the stack segment limit was exceeded.
During instruction execution, the effective address of one of the segment
registers used for the operand points to an illegal memory location.
One of the instruction data operands falls outside the address range 00000h
to 0FFFFh.
A page fault resulted from the execution of the instruction.
An exception is pending due to the floating-point execution unit.
