ia32 instruction sets

ia32 instruction sets

[Frederic Beuserie]

hi,

i've downloaded the references from intel for ia32/P4 cpus and it appears it's not really easy to use it as a "hand" reference (pdf, ...)

did you know a location where there's a comprensive and easily browseable reference of ia32 instructions, coupled with the syntax i gas use.

thanks.

frederic b.

afaik, no comprehensive ia32 doc wrt att syntax exists but, some more or 
less incomplete, 'translations'.

the easiest choice, if sufficient, would be the "nasm" documentation, 
which can be generated in almost any commonly used output format.

best,

Hello  Everyone!!

	I was just looking at the asm code generated by gcc. I could not get some of the stuffs, here, I'm familiar with
nasm assembler syntax, but this does not seem to be nasm syntax. 

 the code is for the following c program
int main()
{
	char *c ="1"
	c[0]= "2" ;
}


asm code for the above..

  .file   "temp.c"
        .section        .rodata
.LC0:
        .string "1"
        .text
        .align 2
.globl main
        .type   main,@function
main:
        pushl   %ebp
        movl    %esp, %ebp
        subl    $8, %esp
        andl    $-16, %esp
        movl    $0, %eax
        subl    %eax, %esp
        movl    $.LC0, -4(%ebp)
        movl    -4(%ebp), %eax
        movb    $50, (%eax)
        leave
        ret
.Lfe1:
        .size   main,.Lfe1-main
        .ident  "GCC: (GNU) 3.2"

  what syntax is this, and what does $ represent. does the .rodata mean readonly data?

 Thanks in advance..

Hi !

  On Linux , the gcc compiler produces intermediate 
assembly code in  the AT&T syntax fromat .

$ refers to the immediate value . 

Google to find more about AT&T syntax .

Cheers !

hi vadiraj,
you're right, its not nasm syntax.....its gas (GNU assembler) syntax....
