x86 shift and rotate instructions

Question 1

This shifts the source operand to the left from 1 to 31 bit positions, while the empty bit positions are cleared. Then the CF flag is loaded with the last bit shifted out of the operand

Answer 1

SAL Op, Qty

Question 2

This shifts the source operand to the right from 1to 31 bit positions, while the empty bit positions are cleared if the operand is positive (+) and set if the operand is negative (-). Then, the CF flag is loaded with the last bit shifted out of the operand

Answer 2

SAR Op, Qty

Question 3

This shifts the source operand right by from 1 to 31 bit positions, while empty bit positions are cleared, and the CF flag is loaded with the last bit shifted out

Answer 3

SHR Op, Qty

Question 4

This rotates bits to the left, with wraparound. Then, the CF flag is loaded with the last bit shifted out of the operand.

Answer 4

ROL Op, Qty

Question 5

This rotates bits to the right, with wraparound. Then, the CF flag is loaded with the last bit shifted out of the operand.

Answer 5

ROR Op, Qty

Question 6

This rotates bits to the left, including the CF flag, with wraparound. This instruction treats the CF flag as a 1-bit extension on the upper end of the operand.

Answer 6

RCL Op, Qty

Question 7

This rotates bits to the right, including the CF flag, with wraparound. This instruction treats the CF flag as a 1-bit extension on the lower end of the operand.

Answer 7

RCR Op, Qty
