# This is part of a GNU Makefile, included by the Makefiles in
# each of the subdirectories.  
#
# This file includes all of the baseline code provided by Nachos.
# Whenever you add a .h or .cc file, put it in the appropriate 
# _H,_C, or _O list.
#
# The dependency graph between assignments is:
#   1. THREADS before everything else
#   2. USERPROG must come before VM
#   3. USERPROG can come before or after FILESYS, but if USERPROG comes 
#	before (as in this distribution), then it must define FILESYS_STUB
#
#   Other than that, you have complete flexibility.
#
# Also whenever you change the include structure of your program, you should 
# do a gmake depend in the subdirectory -- this will modify the Makefile
# to keep track of the new dependency.

# You might want to play with the CFLAGS, but if you use -O it may
# break the thread system.  You might want to use -fno-inline if
# you need to call some inline functions from the debugger.
