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)
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.
