X86 INSTRUCTIONS:::::DATA TRANSFER INSTRUCTION::::::1- MOVE

Data Transfer Some of the most important and most frequently used instructions are those that move data. Without them, there would be no way for registers or memory to even have anything in them to operate on. Data Transfer Instructions Move Syntax : mov src, dest #GAS Syntax mov dest, src #Intel syntax Move : The mov instruction copies the src operand into the dest operand. Operands src Immediate Register Memory dest Register Memory Modified flags No FLAGS are modified by this instruction Example : .data value: .long 2 .text .global _start _start: movl $6, %eax # %eax is now 6 movw %ax, value # value is now 6 movl $0, %ebx # %ebx is now 0 movb %al, %bl # %ebx is now 6 movl value, %ebx # %ebx is now 6 movl $value, %esi # %esi is now the address of value xorl %ebx, %ebx # %ebx is now 0 movw value(, %ebx, 1), %bx # %ebx is now 6 # Linux sys_exit mov $1, %eax xorl %ebx, %ebx int $0x80
