Which of the shift, rotate, and logical instructions do not affect the zero flag? 8 Which flag(s) does the 80x86 use to check for unsigned arithmetic Zero flag (ZF), Sign flag (SF) and parity flag (PF)are updated to reflect the result. Carry flag (CF): Contains the last bit shifted out. Overflow flag (OF) There are three shift instructions---SAR, SHR, and SHL. The "shift-left'' instruction, SHL, shifts the highest bit of the operand into the Carry flag and fills Most often, it means “ROtate Left.” This shifts all the bits left, and shifts new bits in at the right that are based on the bits shifted out on the left. Shifting means to move bits right and left inside an operand. • All of the Shift and Rotate instructions affect. Overflow and Carry Flags. Bits rotated out of an operand are not lost as in a shift, but are "circled" back into the other "end" of the operand. Rotates affect only the carry and the MOVZX instruction fills (extends) the upper half of No operands are modified, but the flags are affected. Shift and Rotate Instructions. Increment instructions affect the flag bits, as do most other arithmetic and logic operations. −The difference is that increment instructions do not affect
