Rotate instructions in x86 assembly language

There are four rotate instructions in x86 assembly language: ROR(rotate right), ROL(rotate left), RCR(rotate right through carry), RCL(rotate left through carry).

Possible instruction formats are:
ROR/ROL/RCR/RCL register, 8-bit immediate operand
ROR/ROL/RCR/RCL register, CL
ROR/ROL/RCR/RCL memory location, 8-bit immediate operand
ROR/ROL/RCR/RCL memory location, CL

The second operand determines for how many bits the first operand is rotated.

The rotate right(ROR) instruction shifts all the bits towards less significant bit positions, except for the LSB, which is rotated to the MSB location. Also, the LSB is copied to the carry flag....
