x86-64 ASM - Instructions 1

With two operand instructions, read Intel as destination <- source(s) whereas AT&T syntax will be source(s) -> destination. In AT&T, registers will also be prefixed with % and immediates will be prefixed with $.

Instruction	What it does
NOP	Represents doing nothing. Useful for timing and NOP slides
CALL	Transfers control to another function. It does this by first pushing the next instruction onto the stack then changing RIP to the address given in the instruction
RET	Pops the top of the stack into RIP. Can also specify bytes to add to RSP
MOV	Move value from source to destination. Source will remain unchanged. CANNOT move from memory to memory. Must use a register
ADD	Add value from source to destination and save to destination. CANNOT do memory to memory
SUB	Subtract value of source from destination and save to destination. CANNOT do memory to memory
