copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|

to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|

designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

## Introduction<a name="section11660541593"></a>
|
||||
|
||||
ARK is a unified programming platform developed by Huawei. Its key components include a compiler, toolchain, and runtime. ARK supports compilation and running of high-level programming languages on the multi-chip platform and accelerates the running of the OpenHarmony operating system and its applications and services on mobile phones, PCs, tablets, TVs, automobiles, and smart wearables. The ARK-JS open sourced this time provides the capability of compiling and running the JavaScript \(JS\) language on the OpenHarmony operating system.
|
||||
|
||||
The ARK-JS consists of two parts: JS compiler toolchain and JS runtime. The JS compiler toolchain compiles JS source code into ARK bytecodes. The JS runtime executes the generated ARK bytecodes. Unless otherwise specified, bytecodes refer to ARK bytecodes in this document.
|
||||
|
||||
The following figure shows the architecture of the JS compiler toolchain.
|
||||
|
||||
|
||||
|
||||
The JS front-end compiler parses the JS source code into an abstract syntax tree \(AST\), which is processed by the AST transformer, bytecode generator, and register allocator. The native emiter generates the ARK bytecode file \(.abc\).
|
||||
|
||||
The following figure shows the JS runtime architecture.
|
||||
|
||||
|
||||
|
||||
ARK-JS Runtime runs ARK bytecode files to implement JS semantic logic.
|
||||
|
||||
ARK-JS Runtime consists of the following:
|
||||
|
||||
- Core Runtime
|
||||
|
||||
Core Runtime consists of basic language-irrelevant runtime libraries, including ARK File, Tooling, and ARK Base. ARK File provides bytecodes. Tooling supports Debugger. ARK Base is responsible for implementing system calls.
|
||||
|
||||
- Execution Engine
|
||||
|
||||
The Execution Engine consists of an interpreter that executes bytecodes, Inline Caches that store hidden classes, and Profiler that analyzes and records runtime types.
|
||||
|
||||
- ECMAScript Runtime
|
||||
|
||||
ECMAScript Runtime consists of the JS object allocator, garbage collector \(GC\), and an internal library that supports ECMAScript specifications.
|
||||
|
||||
- ARK Foreign Function Interface \(AFFI\)
|
||||
|
||||
The AFFI provides a C++ function interface for ARK-JS runtime.

This section describes how to develop and test ARK runtime.
|
||||
|
||||
## HelloWorld<a name="section105987593810"></a>
|
||||
|
||||
Preparations
|
||||
|
||||
1. Run the following command to compile ARK runtime:
|
||||
|
||||
```
|
||||
./build.sh --product-name Hi3516DV300 --build-target ark_js_runtime
|
||||
```
|
||||
|
||||
1. Run the following command to compile the ARK frontend:
|
||||
|
||||
```
|
||||
./build.sh --product-name Hi3516DV300 --build-target ark_ts2abc_build
|
||||
```
|
||||
|
||||
Note: Run the compilation commands in the project root directory.
|
||||
|
||||
Running **hello-world.js**
|
||||
|
||||
Create the **hello-world.js** file and write the following source code into the file:
|
||||
|
||||
```
|
||||
print("Hello World!!!");
|
||||
```
|
||||
|
||||
Run the **hello-world.js** file.
|
||||
|
||||
1. Use the ARK frontend to create the **hello-world.abc** file.
|
||||
|
||||
```
|
||||
node --expose-gc /your code path/out/ohos-arm-release/clang_x64/ark/ark/build/src/index.js hello-world.js
|
||||
```
|
||||
|
||||
2. Run the **hello-world.abc** file.
|
||||
1. Set the search path.
|
||||
|
||||
```
|
||||
export LD_LIBRARY_PATH=/your code path/prebuilts/clang/ohos/linux-x86_64/llvm/lib/:/your code path/out/ohos-arm-release/clang_x64/ark/ark:/your code path/out/ohos-arm-release/clang_x64/global/i18n_standard
|
||||
```
|
||||
|
||||
2. Run **ark\_js\_vm**.
|
||||
|
||||
```
|
||||
/your code path/out/ohos-arm-release/clang_x64/ark/ark_js_runtime//ark_js_vm hello-world.abc _GLOBAL::func_main_0
|
||||
```
|
||||
|
||||
The execution result is as follows:
|
||||
|
||||
```
|
||||
Hello World!!!
|
||||
```
|
||||
|
||||
|
||||
|
||||
> **NOTE:**
|
||||
>In the preceding command, _your code path_ indicates the source code directory.
|
||||
|
||||
Disassembling **hello-world.abc**
|
||||
|
||||
Run the following command to export the result to the **output** file:
|
||||
|
||||
```
|
||||
./your code path/out/ohos-arm-release/clang_x64/ark/ark/ark_disasm hello-world.abc output
|
||||
```
|
||||
|
||||
The output is as follows:
|
||||
|
||||
```
|
||||
#
|
||||

# Overview<a name="EN-US_TOPIC_0000001174295771"></a>
|
||||
|
||||
ARK is a unified programming platform developed by Huawei. Its key components include a compiler, toolchain, and runtime. ARK supports compilation and running of high-level programming languages on the multi-chip platform and accelerates the running of the OpenHarmony standard operating system and its applications and services on mobile phones, PCs, tablets, TVs, automobiles, and smart wearables. The ARK-JS open sourced this time provides the capability of compiling and running the JavaScript \(JS\) language on the OpenHarmony operating system.
|
||||
|
||||
The ARK-JS consists of two parts: JS compiler toolchain and JS runtime. The JS compiler toolchain compiles JS source code into ARK bytecodes. The JS runtime executes the generated ARK bytecodes. Unless otherwise specified, bytecodes refer to ARK bytecodes in this document.
|
||||
|
||||
The following figure shows the architecture of the JS compiler toolchain.
|
||||
|
||||
|
||||
|
||||
The ARK-JS source code compiler receives the JS source code, and ts2abc converts the JS source code into an abc file.
|
||||
|
||||
The following figure shows the JS runtime architecture.
|
||||
|
||||
|
||||
|
||||
ARK-JS Runtime runs ARK bytecode files to implement JS semantic logic.
|
||||
|
||||
ARK-JS Runtime consists of the following:
|
||||
|
||||
- Core Runtime
|
||||
|
||||
Core Runtime consists of basic language-irrelevant runtime libraries, including ARK File, Tooling, and ARK Base. ARK File provides bytecodes. Tooling supports Debugger. ARK Base is responsible for implementing system calls.
|
||||
|
||||
- Execution Engine
|
||||
|
||||
The Execution Engine consists of an interpreter that executes bytecodes, Inline Caches that store hidden classes, and Profiler that analyzes and records runtime types.
|
||||
|
||||
- ECMAScript Runtime
|
||||
|
||||
ECMAScript Runtime consists of the JS object allocator, garbage collector \(GC\), and an internal library that supports ECMAScript specifications.
|
||||
|
||||
- ARK Foreign Function Interface \(AFFI\)
|
||||
|
||||
The AFFI provides a C++ function interface for ARK-JS runtime.
|
||||
|
||||
|
||||
Future plan:
|
||||
|
||||
- High-performance TypeScript support
|
||||
|
||||
OpenHamony uses TypeScript \(TS\) as one of its main development languages. TS is simply JS with syntax for static types. The common way to process TS in the industry is to convert TS into JS and execute JS code with JS runtime.
|
||||
|
||||
ARK-JS is planned to support the native TS. When compiling the TS source code, ts2abc analyzes and obtains the TS type information and sends the TS type information to ARK-JS runtime. The ARK-JS runtime directly uses the type information to statically generate an inline cache to accelerate bytecode execution.
|
||||
|
||||
The TS Ahead of Time \(AOT\) compiler directly converts the source code into high-quality machine code based on the TS type information sent from ts2abc, which greatly improves the running performance.
|
||||
|
||||
- Lightweight Actor concurrency model
|
||||
|
||||
ECMAScript does not provide concurrency specifications. The Actor concurrency model is used in the JS engines in the industry to implement concurrent processing. In this model, executors do not share data and communicate with each other using the messaging mechanism. The JS Actor model \(web-worker\) in the industry has defects such as slow startup and high memory usage. ARK-JS is required to provide the Actor implementation that features fast startup and low memory usage to better leverage the device's multi-core feature to improve performance.
|
||||
|
||||
ARK-JS is planned to share immutable objects, built-in code blocks, and method bytecodes in Actor instances based on the Actor memory isolation model to accelerate the startup of JS Actor and reduce memory overhead and implement the lightweight Actor concurrency model.

# Using the Toolchain<a name="EN-US_TOPIC_0000001128256014"></a>
|
||||
|
||||
The ARK front-end tools use the command line interaction mode and convert JS code into ARK bytecodes that can run on ARK runtime. The toolchain supports Windows, Linux, and macOS.

本章节将介绍基于方舟运行时的开发测试实例。
|
||||
|
||||
## HelloWorld<a name="section105987593810"></a>
|
||||
|
||||
运行前准备
|
||||
|
||||
1. 编译方舟运行时，编译命令：
|
||||
|
||||
```
|
||||
./build.sh --product-name Hi3516DV300 --build-target ark_js_runtime
|
||||
```
|
||||
|
||||
1. 编译方舟前端，编译命令：
|
||||
|
||||
```
|
||||
./build.sh --product-name Hi3516DV300 --build-target ark_ts2abc_build
|
||||
```
|
||||
|
||||
_注：编译命令执行路径为项目根目录。_
|
||||
|
||||
运行hello-world.js
|
||||
|
||||
新建hello-world.js文件，写入以下源码：
|
||||
|
||||
```
|
||||
print("Hello World!!!");
|
||||
```
|
||||
|
||||
运行步骤：
|
||||
|
||||
1. 通过方舟前端生成hello-world.abc文件，编译命令：
|
||||
|
||||
```
|
||||
node --expose-gc /your code path/out/ohos-arm-release/clang_x64/ark/ark/build/src/index.js hello-world.js
|
||||
```
|
||||
|
||||
2. 执行hello-world.abc文件：
|
||||
1. 设置搜索路径：
|
||||
|
||||
```
|
||||
export LD_LIBRARY_PATH=/your code path/prebuilts/clang/ohos/linux-x86_64/llvm/lib/:/your code path/out/ohos-arm-release/clang_x64/ark/ark:/your code path/out/ohos-arm-release/clang_x64/global/i18n_standard
|
||||
```
|
||||
|
||||
2. 执行ark\_js\_vm：
|
||||
|
||||
```
|
||||
/your code path/out/ohos-arm-release/clang_x64/ark/ark_js_runtime//ark_js_vm hello-world.abc _GLOBAL::func_main_0
|
||||
```
|
||||
|
||||
执行结果如下：
|
||||
|
||||
```
|
||||
Hello World!!!
|
||||
```
|
||||
|
||||
|
||||
|
||||
> **说明：**
|
||||
>此处“_your code path_”为源码目录路径。
|
||||
|
||||
反汇编hello-world.abc
|
||||
|
||||
执行如下命令，结果输出到output文件中：
|
||||
|
||||
```
|
||||
./your code path/out/ohos-arm-release/clang_x64/ark/ark/ark_disasm hello-world.abc output
|
||||
```
|
||||
|
||||
hello-world.abc反汇编结果如下：
|
||||
|
||||
```
|
||||

## 简介<a name="section11660541593"></a>
|
||||
|
||||
方舟\(ARK\)是华为自研的统一编程平台，包含编译器、工具链、运行时等关键部件，支持高级语言在多种芯片平台的编译与运行，并支撑OpenHarmony操作系统及其应用和服务运行在手机、个人电脑、平板、电视、汽车和智能穿戴等多种设备上的需求。本次开源的ARK-JS提供的能力是在OpenHarmony操作系统中编译和运行JavaScript语言\(本文后面简称JS\)。
|
||||
|
||||
本次开源的ARK-JS分成两个部分，分别是JS编译工具链与JS运行时。JS工具链将JS源码编译成方舟字节码\(ARK Bytecode\)，JS运行时负责执行生成的方舟字节码\(后续如无特殊说明，字节码特指方舟字节码\)。
|
||||
|
||||
JS编译工具链架构：
|
||||
|
||||
|
||||
|
||||
js前端编译器，将JavaScript源码解析为AST后，经过AST变换、字节码生成器、寄存器分配后由native emiter产生方舟字节码文件\(abc文件\)
|
||||
|
||||
JS运行时（Runtime）架构：
|
||||
|
||||
|
||||
|
||||
ARK-JS Runtime以方舟字节码文件作为输入并直接运行字节码文件，实现对应的JS语义逻辑。
|
||||
|
||||
ARK-JS Runtime主要由四个部分组成：
|
||||
|
||||
- Core Runtime
|
||||
|
||||
Core Runtime主要由语言无关的基础运行库组成，包括承载字节码的ARK File组件、支持Debugger的Tooling组件、负责对应系统调用的ARK Base组件等。
|
||||
|
||||
- Execution Engine
|
||||
|
||||
执行引擎目前包含执行字节码的解释器、缓存隐藏类和内联缓存、以及剖析记录运行时类型的Profiler。
|
||||
|
||||
- ECMAScript Runtime
|
||||
|
||||
ECMAScript Runtime则包含了各种JS对象的分配器、垃圾回收器、以及用以支撑ECMAScript规范的内部运行库。
|
||||
|
||||
- AFFI \(ARK Foreign Function Interface\)
|
||||
|
||||
AFFI是ARK JS运行时的C++语言外部函数接口。

方舟\(ARK\)是华为自研的统一编程平台，包含编译器、工具链、运行时等关键部件，支持高级语言在多种芯片平台的编译与运行，并支撑OpenHarmony标准操作系统及其应用和服务运行在手机、个人电脑、平板、电视、汽车和智能穿戴等多种设备上的需求。本次开源的ARK-JS提供的能力是在OpenHarmony操作系统中编译和运行JavaScript语言\(本文后面简称JS\)。

|
||||
|
||||
JS编译工具链架构：
|
||||
|
||||
|
||||
|
||||
ARK-JS的源码编译器接收JS源码的输入，再由ts2abc（将JavaScript文件转换为字节码的工具）转化为abc文件。
|
||||
|
||||
JS运行时（Runtime）架构：
|
||||
|
||||
|
||||
|
||||
ARK-JS Runtime以方舟字节码文件作为输入并直接运行字节码文件，实现对应的JS语义逻辑。
|
||||
|
||||
ARK-JS Runtime主要由四个部分组成：
|
||||
|
||||

|
||||

|
||||

||||

|
||||
|
||||
执行引擎目前包含执行字节码的解释器、缓存隐藏类和内联缓存、以及剖析记录运行时类型的Profiler。
|
||||
|
||||
- ECMAScript Runtime
|
||||
|
||||
ECMAScript Runtime则包含了各种JS对象的分配器、垃圾回收器、以及用以支撑ECMAScript规范的内部运行库。
|
||||
|
||||
- AFFI \(ARK Foreign Function Interface\)
|
||||
|
||||
AFFI是ARK-JS运行时的C++语言外部函数接口。
|
||||
|
||||
|
||||
未来规划：
|
||||
|
||||
- 高性能TypeScript支持
|
||||
|
||||
OpenHamony目前选用了TS（TypeScript）作为主要开发语言之一，而TS简单地概括就是具有静态类型的JS。业界通用的执行方式是把TS转化为JS，再使用JS运行时来执行生成的JS代码。
|
||||
|
||||
ARK-JS规划原生支持TS。在ts2abc编译TS源码时，会推导分析TS的类型信息并传递给ARK-JS运行时，运行时直接利用类型信息静态生成内联缓存从而加速字节码执行。
|
||||
|
||||
TS AOT \(Ahead of Time\) Compiler，利用ts2abc传递的类型信息，直接编译生成高质量的机器码，使得应用可以直接以机器码形式运行，提升运行性能。
|
||||
|
||||
- 轻量级Actor并发模型
|
||||
|
||||
ECMAScript没有提供并发规范，业界JS引擎的实现中常用Actor并发模型。此模型下执行体之间不共享任何数据，通过消息机制进行通信。业界当前实现的JS Actor模型（web-worker）有启动速度慢、内存占用高这些缺陷。为了利用设备的多核能力获得更好的性能提升，ARK-JS需要提供启动快、内存占用少的Actor实现。
|
||||
|
||||
ARK-JS规划在Actor内存隔离模型的基础上，共享actor实例中的不可变或者不易变的对象、内建代码块、方法字节码等，来提升JS Actor的启动性能和节省内存开销，达到实现轻量级Actor并发模型的目标。
