README

        
This is a toolchain for a parallel processor architecture called

[Nyuzi](https://github.com/jbush001/NyuziProcessor), based on

[LLVM](http://llvm.org/).  It includes a C/C++ compiler (clang), assembler,

linker and debugger (lldb).

While this project includes a C/C++ compiler, the LLVM backend can support

any language.

Questions or issues can be directed to the [mailing list](https://groups.google.com/forum/#!forum/nyuzi-processor-dev) or...

# Building

The NyuziProcessor repository README has instructions for building this as

well. These instructions are only necessary if you want to build this

separately.

## Required Software

The following sections describe how to install these packages.

- gcc 4.8+ or Apple clang 4.2+

- cmake 3.4.3+

- python 2.7

- libxml (including headers)

- zlib (including headers)

- bison 2.7+

- flex 2.5+

- swig 3.0.11+ (http://www.swig.org/) with python wrappers

- libedit (http://thrysoee.dk/editline/)

- ncurses

- ninja 1.3+

## Building on Linux

You can install required packages using the built-in package manager (apt-get,

yum, etc). As LLVM needs newer versions of many packages, you should be on

a recent version of your Linux distribution. Instructions are below are for Ubuntu

(which must be on at least version 16). You may need to change the package names

for other distributions:

    sudo apt-get install libxml2-dev cmake gcc g++ python bison flex \

        zlib1g-dev swig python-dev libedit-dev libncurses5-dev ninja-build

    git clone [email protected]:jbush001/NyuziToolchain.git

    cd NyuziToolchain

    mkdir build

    cd build

    cmake -G Ninja ..

    ninja

    sudo ninja install

## Building on MacOS

On Mavericks and later, you can install the host command line compiler like this:

    xcode-select --install

On earlier versions, you can download XCode from the app store. You will also

need to install a package manager like [Homebrew](https://brew.sh/) to

get the remaining dependencies. Open a new terminal to do the build after

installing Brew, because it installs alternate versions of some utilities

and updates the PATH. Once you have done this:

    brew install cmake bison swig sdl2 emacs ninja

    git clone https://github.com/jbush001/NyuziToolchain.git

    cd NyuziToolchain

    mkdir build

    cd build

    cmake -G Ninja ..

    ninja

    sudo ninja install

**Upgrading 'flex' using the package manager may cause build errors. I

would recommend using the system supplied version.**

## Building on Windows

I have not tested this natively on Windows. Many of the libraries are already cross

platform, so it should theoretically be possible.

## Other Notes

* The toolchain is installed into /usr/local/llvm-nyuzi/

* The triple for this target is 'nyuzi-'.

## Tests

Change PATH environment variable to include the binary directory (build/bin). This is only required

for llvm-lit based tests. Run the tests as follows (assuming you are at the top of the project

directory):

```

export PATH=/build/bin:$PATH

llvm-lit test

llvm-lit tools/clang/test/CodeGen/

llvm-lit tools/lld/test/ELF/nyuzi-*

```

All tests should pass.

* The command above for the LLD tests uses a wildcard to only run tests for the Nyuzi

target. This is because many tests are architecture specific but don't specify a

REQUIRES line in the file. They are assuming LLVM is built for all architectures,

where I have modified the build files in this project to only build for Nyuzi.*

It is also useful to run the

[random test generator](https://github.com/jbush001/NyuziToolchain/wiki/Validating-LLVM-with-random-programs)

to validate the backend.

There is a set of whole-program tests in the NyuziProcessor repository

[test/whole-program](https://github.com/jbush001/NyuziProcessor/tree/master/tests/whole-program)

Each test case is compiled and then run in the instruction set simulator, which

checks the output for validity. This is similar to the test-suite project in LLVM.

Instructions are in that directory.

In the same repository, there is also a test to validates the LLDB debugger by

running a real program in the emulator:

[tests/tools/lldb](https://github.com/jbush001/NyuziProcessor/tree/master/tests/tools/lldb)
