I m trying to learn assembly language. i have intel processor . please suggest e some good books of intel instruction set and also want to know that how to run assemble prog from terminal..

thanks in advance.

You can also run assembler code directly from C, here's an a post which uses an example from Linus Torvalds demonstrating the performance of the cmov instruction (bad on out-of-order processors (most modern ones are), good on in-order processors like the intel atom)

Use 'as' and 'ld' from the binutils package

# hello.s

	.section .data
hello:	
	.ascii 	"Hello, world!\n"
hello_len:
	.long 	. - hello

	.section .text
	.globl _start
	
_start:
	## display string using write () system call
	xorl %ebx, %ebx		# %ebx = 0
	movl $4, %eax		# write () system call
	xorl %ebx, %ebx		# %ebx = 0
	incl %ebx		# %ebx = 1, fd = stdout
	leal hello, %ecx	# %ecx ---> hello
	movl hello_len, %edx	# %edx = count
	int $0x80		# execute write () system call
	
	## terminate program via _exit () system call 
	xorl %eax, %eax		# %eax = 0
	incl %eax		# %eax = 1 system call _exit ()
	xorl %ebx, %ebx		# %ebx = 0 normal program return code
	int $0x80		# execute system call _exit ()

$ as -o hello.o hello.s
$ ld -o hello -O0 hello.o

$ ./hello 
Hello, world!

(use 'objdump -d hello' to check the assembly code is correct)

use this....for doing it in a C program. usually ya need to add some commands to the makefile, which depends on what you do in the assembly. Otherwise just make it a <name>.S. which is the usual way assembly programs are labeled in linux. though some times you get funcy names form windows
