Shift bits of a 64-bit destination
register or memory operand to the
right the number of bits specified in
the CL register, while shifting in
bits from the second operand.
Set the carry flag (CF) to 1.
Set the direction flag (DF) to 1.
Store the contents of the AL register
to ES:rDI, and then increment or
decrement rDI.
Store the contents of the AX register
to ES:rDI, and then increment or
decrement rDI.
Store the contents of the EAX
register to ES:rDI, and then
increment or decrement rDI.
Store the contents of the RAX
register to ES:rDI, and then
increment or decrement rDI.
Store the contents of the AL register
to ES:rDI, and then increment or
decrement rDI.
Store the contents of the AX register
to ES:rDI, and then increment or
decrement rDI.
Store the contents of the EAX
register to ES:rDI, and then
increment or decrement rDI.
Store the contents of the RAX
register to ES:rDI, and then
increment or decrement rDI.

from the AL register and store the
result in AL.
Subtract an immediate 16-bit value
from the AX register and store the
result in AX.

from the EAX register and store the
result in EAX.

32-bit value from the RAX register
and store the result in RAX.

from a 16-bit destination register or
memory location.

from a 32-bit destination register or
memory location.
