Assembly basics—arithmetic shift, logic shift, cyclic shift, cyclic shift with carry

tags: compilation C language Development language rear end

The arithmetic left shift and the logical left shift are both right-handed 0.
To move the logic right, just move the binary number as a whole right and add 0 to the left.
After the arithmetic shifts right, the binary number should be filled with the sign bit on the left.
Arithmetic left shift and arithmetic right shift are mainly used to multiply signed numbers and reduce them by half;
Logical left shift and logical right shift are mainly used to multiply unsigned numbers. Half.
