################################################################################
##
## 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.

# 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.
