# This is a template that can be used as a starting point for 
# writing assembly code functions, not just main().

# data section: global vars
	.data
x:	.long 7		# x = 7
y:	.long 23	# y = 23

# bss section: un-initialized global vars
	.bss
z:	.long		# global var z

# text section: code
	.text
format:		.ascii "Hello world\0"

#
# Function: _main()
# void _main()
# This function is a shell demonstrating how to setup the entry, 
# body and exit parts of a function.

    .globl _main		# required by linker to find _main()
_main:

	pushl %ebp		# enter _main(), save caller's FP
	movl %esp, %ebp	# set our FP

	pushl %ebx		# save regs we change in this function
	pushl %edi
	pushl %esi

	#
	# your code goes here!
	#

	pop %esi		# restore regs that we saved at the top
	pop %edi
	pop %ebx

	movl %ebp, %esp	# exit _main(), restore caller's SP
	pop %ebp		# restore caller's FP
	ret
