INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

this assignment is about writing the "cat" program in assembly, using the AT&T syntax, without reading / writing 1 char at a time. Obviously, the code needs to be written by a human (not by simply doing gcc -s on a c file)..

 

SUBMISSION FILES AUTHORIZED FUNCTIONS

Cat/ open(2) close(2)

Cat. S /7 read(2) write(2)

Goal

You have to implement a program that opens the file given as argument and prints it on the standard output.

. If there is not enough or too many arguments, the program must return 1.

. If the file cannot be opened, the program must return 2.

Otherwise, O is returned.

You must avoid reading/writing 1 char at a time.

Example

42sh$ cat -e foo

Hello$

World$

42sh$gcc -o cat cat.S

42sh$. /cat foo I cat -e

Hello$

World $
