Web26 feb. 2024 · The basic unit of assembly language is the instruction. Each machine instruction is a small operation, like adding two numbers, loading some data from memory, jumping to another memory location (like the dreaded goto statement), or calling or returning from a function. (The x86 architecture has lots of not-so-small instructions as well. Web6.1.2 Preprocessed by Shifter o LSL: logical shift left n x << y, the least significant bits are filled with zeroes o LSR: logical shift right: n (unsigned) x >> y, the most significant bits are filled with zeroes o ASR: arithmetic shift right n (signed) x >> y, copy the sign bit to the most significant bit o ROR: rotate right n ((unsigned) x >> y) (x << (32-y))
