Topic created on: July 13, 2011 19:44 CDT by Illiac .

Hey All,

Just a random Assembler (x86) question.
I got the following code that I can't change:

  .globl function_name;
  .align 4, 0x90;
  function_name:
    xor   eax, eax
    mov    ah, 0x02
    mov    dl, 0xda
    mov    dh, 0xde


I require to get the the function addr of the function written in assembler.
I can write this code in either asm or C.

Any advice? I know how to do it if the target function is in C but in this case I should have a way to &'it' so I can get the functions address.

Hope to get a pointer to a document. (hehe a 'pointer' get it.. (hehe))

Cheers,
  Illiac.

Maybe i'm misunderstanding your question.
But seem lea instruction is what you're looking for, is't it?

D'oh of course.
I knew it couldn't be hard.
