//
//	This file defines a function that computes the sum of 
//	the two integers whose values are transmitted via the
//	stack (and returns their total in the %eax register).
//	The values in other cpus register (except EFLAGS) are 
//	preserved.  The function's entry-point is declared to 
//	be a global symbol so that the linker can combine the
//	object-code with other, separately assembled modules.    
//
//	assemble using:	$ as myplus.s -o myplus.o
//	or alternately: $ gcc -c myplus.s
