# OpenArkCompiler ## Overview ----------------- > Unified programming platform supporting multiple devices and languages OpenArkCompiler is Huawei's open source project. ### Four Technical Features of OpenArkCompiler ### Compiles code of different languages into a set of executable files and efficiently executes the files in the running environment. - Supports joint optimization of multiple languages and eliminates cross-language calling overhead. - Achieves lightweight language runtime. - Collaborates hardware and software to maximize hardware energy efficiency. - Supports diversified terminal platforms. ## 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 | |Middle end |Weekly open source optimization phase | | |Back end |Backend open source (O0) (aarch64)|Weekly open source optimization (O2) (aarch64)| |Test framework|Test framework and basic Cases| | **Updating...** ## How to use - source build/envsetup.sh arm release or - source build/envsetup.sh arm debug - make setup - make - make libcore - make testall C example: - make demo ## OpenArkCompiler Incubator - FutureWei Mapleall https://gitee.com/openarkcompiler-incubator/mapleall - Maple Engine https://gitee.com/openarkcompiler-incubator/maple_engine - Maple FrondEnd https://gitee.com/openarkcompiler-incubator/MapleFE - Maple clang2mpl https://gitee.com/openarkcompiler-incubator/clang2mpl ## Related Documents - Architecture Design Principles - [MAPLE IR Design](doc/en/MapleIRDesign.md) - [RC API](doc/en/RcApi.md) - [Naive RC Insertion Principle](doc/en/NaiveRcInsertionDescription.md) - [Virtual Table and Interface Table Design](doc/en/VtableItableDescription.md) - [Phase Design](doc/en/CompilerPhaseDescription.md) - [Application Manual of Maple General Modules](doc/en/DeveloperGuide4Utility.md) - [Environment Configuration](doc/en/DevelopmentPreparation.md) - [Developer Guide](doc/en/DeveloperGuide.md) - [Programming Specifications](doc/en/ProgrammingSpecifications.md) - [Discussion of Pointer in C++ Programming](doc/en/CPPCodingTalkAboutPointer.md) ## License - [LICENSE](license/LICENSE) ## Real-time Chat Channel - [Discord-OpenArkCompiler](https://discord.gg/CJeJWQXxMP) - 9:00 am - 10:30 am everyday, developers can discuss community issues in the voice channel "panel discussion" - [Discord-MapleFE](https://discord.gg/sBj3cc4GhM) - we have weekly meeting about projects related to MapleFE
