# CS444 hw5 makefile
# Usage "make"  to build uprog123.lnx
#     "make U=testmutex" to build testmutex.lnx
# makefile for building C or assembly language programs for the
# Standalone 486 or Pentium IBM PC running in 32-bit protected mode, 
# or "SA PC" for short.
# also "make clean" to clean up non-source files in a directory

# system directories needed for compilers, libraries, header files--
# assumes the environment variables SAPC_TOOLS, SAPC_GNUBIN, and SAPC_SRC
# are set up, usually by the ulab module

# File suffixes:
# .c	C source (often useful both for UNIX host and SAPC)
# .s 	assembly language source
# .opc  relocatable machine code, initialized data, etc., for SA PC
# .lnx  executable image (bits as in memory), for SA PC (Linux a.out format)
# .syms text file of .lnx's symbols and their values (the "symbol table")
# Symbol file "syms"--for most recently built executable in directory

# PC executable--tell ld to start code at 0x1000e0, load special startup
# module, special PC C libraries--
# Code has 0x20 byte header, so use "go 100100" (hopefully easier to
# remember than 100020)
