## Filename:    Makefile
4
##
5
## Project:     Zip CPU -- a small, lightweight, RISC CPU soft core
6
##
7
## Purpose:     To direct and simplify the build of a variety of simple assembly
8
##              language test programs which will use one (or both) of the
9
##      ZipCPU simulators.
10
##
11
## Targets include:
12
##
13
##      hellosim
14
##              Using the SIM instruction, prints Hello World to the screen.
15
##
16
##      simuart
17
##              Same as hellosim, but without using the SIM instruction.  This
18
##              *should* be able to run successfully on a verilated or
19
##              synthesized hardware, although I hvae yet to test it there.
20
##
21
##      simtest
22
##              A set of simple tests designed to demonstrate if the simulator
23
##              works or not.
24
##
25
##      clean
26
##              Removes the object file directory and any executables that have
27
##              been created.
28
##
29
##      None of the files/targets below have any dependencies, or if they did,
30
##      GCC can't determine them, so thus there is no make depends step.
31
##
32
##      To actually run one of these programs, list the program on the command
33
##      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
118
# needs to be run through the C pre-processor before it can go through the
119
# assembler.  Hence the build is a tocuh trickier, but still simple enough.
