#
# Filename: Makefile
#
# Project: Zip CPU -- a small, lightweight, RISC CPU soft core
#
# Purpose: To direct and simplify the build of a variety of simple assembly
# language test programs which will use one (or both) of the
# ZipCPU simulators.
#
# Targets include:
#
# hellosim
# Using the SIM instruction, prints Hello World to the screen.
#
# simuart
# Same as hellosim, but without using the SIM instruction. This
# *should* be able to run successfully on a verilated or
# synthesized hardware, although I hvae yet to test it there.
#
# simtest
# A set of simple tests designed to demonstrate if the simulator
# works or not.
#
# clean
# Removes the object file directory and any executables that have
# been created.
#
# None of the files/targets below have any dependencies, or if they did,
# GCC can't determine them, so thus there is no make depends step.
#
# To actually run one of these programs, list the program on the command
# line with the ZipCPU simulator, zsim.

# simtest

# This is just a simple series of instruction tests that should be able to be
# used to determine whether the simulator has a basic amount of functionality.
# Because the test includes #define, #ifdef, and #endif statements, though, it
# needs to be run through the C pre-processor before it can go through the
# assembler. Hence the build is a tocuh trickier, but still simple enough.
