Data Movement Instructions

• MOV: Move data between registers, memory locations, or immediate values.

Arithmetic and Logical Instructions

• ADD: Perform addition operations on registers or memory locations.
• SUB: Perform subtraction operations on registers or memory locations.
• CMP: Compare two operands and set flags accordingly for conditional branching.
• INC: Increment the value of a register or memory location.
• DEC: Decrement the value of a register or memory location.
• AND: Perform bitwise AND operations on registers or memory locations.
• OR : Perform bitwise OR operations on registers or memory locations.
• XOR: Perform bitwise XOR operations on registers or memory locations.

Control Transfer Instructions

• JMP: Unconditionally jump to a specified location in the program.
• JE/JZ: Jump if equal or zero.
• JNE/JNZ: Jump if not equal or not zero.
• CALL: Call a function or subroutine at a specified memory address.
• RET: Return from a subroutine back to the calling function.

Stack Instructions

• PUSH: Push data onto the stack.
• POP: Pop data from the stack.

Arithmetic Instructions

• MUL: Perform multiplication operations.
• DIV: Perform division operations.

Bit Manipulation Instructions

• SHL/SHR: Shift the bits of a register or memory location left or right.

This is not an exhaustive list, but it covers some of the commonly used X86-64 assembly instructions. For a more comprehensive understanding of the instruction set, refer to the official Intel or AMD documentation.

Note: Understanding assembly language requires familiarity with the underlying computer architecture. It is recommended to study the official documentation and refer to appropriate learning resources for a thorough understanding of X86-64 assembly programming.
