What is EBP in assembly language?
The two special registers ebp (base pointer) and esp (stack pointer) handles call and return mechanisms of subroutine calls. The values are returned to the calling program via register eax.
What is EBP register?
A frame pointer (the ebp register on intel x86 architectures, rbp on 64-bit architectures) contains the base address of the function’s frame. The code to access local variables within a function is generated in terms of offsets to the frame pointer.
What is assembly source code?
An assembly language is a low-level programming language designed for a specific type of processor. It may be produced by compiling source code from a high-level programming language (such as C/C++) but can also be written from scratch. Assembly code can be converted to machine code using an assembler.
What is .LC0 assembly?
LC0 , which is the address of the constant string in the rodata section). Then we call printf() . addl $20, %esp. When printf() returns, we remove the space allocated for the arguments. This addl cancels what the subl above did.
What does EBP 4 mean?
ebp+4 points to the first parameter of your function (or the this value of a class method). ebp-4 points to the first local variable of your function, usually the old value of ebp so you can restore the prior frame pointer.
What is EBP address?
ebp: The ebp register stores the address of the “bottom” of the stack. More precisely, it points to the next byte AFTER the stack. The name ebp stands for extended base pointer, but it is usually just called the base pointer.
Which file is also called the source file?
A source program is a text file that contains instructions written in a high level language. It can not be executed (made to run) by a processor without some additional steps. A source program is also called a source file, source code, or sometimes, just source.
Which one is example of assembly code *?
Typical examples of large assembly language programs from this time are IBM PC DOS operating systems, the Turbo Pascal compiler and early applications such as the spreadsheet program Lotus 1-2-3.
What is Pushl?
Push Long. Description: The long word source operand is pushed onto the top of the stack. Notes: PUSHL is equivalent to MOVL src, -(SP), but is one byte shorter.
What does EBP-4 mean?
