Open Source Plan

Open source compiler framework code

  • Time: August, 2019
  • Scope: Compiler IR and middle-end language implementation
  • Benefits:
    • Provides an open source framework for understanding the architecture and framework code of OpenArkCompiler.
    • Allows developers to build a complete compiler toolchain that supports the compilation of Java samples (non-application).

Subsequent open source scope Open the front end, back end, and compilation optimization of compilers. Support the full compilation of Java programs and JavaScript applications.

Open Source Scope March 2020 May 2020
Front end Jbc front-end basic framework Front-end full open source
