Code: Select all

#PURPOSE:		This program finds the maximum number of 
#				a set of data items
#VARIABLES:		The registers have the following uses:
#
#	%edi - Holds the index of the data item being examined
#	%ebx - Largest data item found
#	%eax - Current data item
#
#	The following memory locations are used:

#	data_items - contains the item data. A 0 is used to terminate data
#
#

.section .data

data_items:			#These are the data items
 .long 3, 67, 34, 222, 45, 75, 54, 34, 44, 33, 22, 11, 66, 0
 
.section .text

.globl _start
_start:
 movl $0, %edi			# move 0 into the index register
 movl data_items (,%edi,4), %eax # load the first byte of data
 movl %eax, %ebx 		#since this is the first item, %eax is the biggest
 
 start_loop:			#start loop
 cmpl $0, %eax			#check to see if we've hit the end
 je loop_exit
 incl %edi				#load the next value
 movl data_items(,%edi,4), %eax
 cmpl %ebx, %eax		#compare values
 jle start_loop			#jump to loop beginning if the new
						#one isnt bigger
movl %eax, %ebx			#move the value as the largest
jmp start_loop			#jump to loop beginning

loop_exit:
#%ebx is the status code for the exit system call
#and it already has the maximum number

movl $1, %eax		#1 is the exit() sys call
