## 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.

# This is just a simple series of instruction tests that should be able to be

# 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.
