destination (first) operand.
In all forms of the MOV instruction, the two operands are the
same size, except for moving between a segment register and an
r/m32 operand. These instructions are treated exactly like the
corresponding 16-bit equivalent (so that, for example, \c{MOV
DS,EAX} functions identically to MOV DS,AX but saves a prefix
when in 32-bit mode), except that when a segment register is moved
into a 32-bit destination, the top two bytes of the result are
undefined.
MOV may not use CS as a destination.
CR4 is only a supported register on the Pentium and above.
Test registers are supported on 386/486 processors and on some
non-Intel Pentium class processors.
