xoc's Introduction

xoc

Welcome to use XOC

What does XOC mean? eXtremely Optimizing Compiler. We build XOC compiler that intent to be a finely honed tool to squeezing the last performance out of ordinary code.

Contribution and License Agreement. If you contribute code to this project, you are implicitly allowing your code to be distributed under the BSD license.

Your ideas have no limits. Surprisingly powerful. Why let programming tools shackle your mind? XOC was designed for extensibility. Tailoring and retargeting the compiler is easy, and fun.

Truly open. XOC is not just open-source, it is open from end to end. You can tune its syntax, add new instructions, integrate arbitrary system capabilities, enforce custom policies, add specific optimizations ...

XOC is a compiler infrastructure that provides multi-level IR operations, flexibility, and the capability of representing almost all popular languages. There are two level IR representations used throughout all phases of the compilation. You can use XOC to perform optimization, program analysis or build diagnostic tools.

Build : cd xoc & make all

How to Contribute : All contributors must sign a contributor license agreement (CLA). A CLA basically says that you own the rights to any code you contribute, and that you give us permission to use that code in XOC. You maintain the copyright on that code. Submit a pull request for your changes. A project developer will review your work and then merge your request into the project.

Lack of unit tests for the project

I am not sure wether this is the right place to ask, my questions is: why there are not any unit tests for this project, how to ensure the correctness of the ir??

what's the use case of such ir

is it optimized for dynamic language? or like llvm ir, by reading the readme file, it is not clear to me

Fixes to build

I just cloned this project (actually https://github.com/stevenknown/xoc but it has not enabled issues there) and tried to build but got some warnings and an error related to try use of HeapSort::HeapValVector<T> hdata(data); with clang++ (6 and 11) and g++9.

Here is the output of git diff -u of my changes to be able to build it:

Allow targets to be added at runtime

Hey @stevenknown. I've been working on a Conan package for XOC.

One issue I see is that XOC builds with its targets at compile time (by default it supports DEX). This makes it hard to make a package because the XOC binary that gets installed by a package manager will only support DEX.

This design is ok for LLVM because it comes with many targets and most users won't make their own target. But XOC only supports DEX so most users will have to implement their own target, which means they cannot use a precompiled package.

I don't know much about the XOC design, but I'm wondering if it's possible to support something like this:

Library header in XOC

// A target interface that users can implement.
class XocTarget {
  virtual void func1() = 0;
  virtual void func2() = 0;
  virtual void func3() = 0;
  ...
};

Application code using XOC

// Implementing our own target.
class CustomTarget : public XocTarget {
  void func1() override;
  ...
};

...

// Now passing it into XOC so the library can use it.
int main(int argc, char** argv) {
  CustomTarget target;
  xoc_register_target(&target);

  REGION_MGR rm;
  rm.init_var_mgr();
  ...
}

If we can't support adding targets at runtime, then I don't think XOC can be packaged. I'm happy to help with the development work.
