1 # 方舟运行时使用指南 2 3 ## 方舟编译器简介 4 5 方舟编译器(ArkCompiler)是为支持多种编程语言、多种芯片平台的联合编译、运行而设计的统一编译运行时平台。 6 7 * ArkCompiler主要分成两个部分：编译工具链与运行时。 8 * ArkCompiler eTS Runtime主要由四个子系统组成：Core Subsystem、Execution Subsystem、Compiler Subsystem、Runtime subsystem。 9 * ArkCompiler 的设计特点：原生支持类型、并发模型优化与并发API、安全。 10 11 要了解虚拟机的详细设计请参考 [概述](overview-zh.md) 12 13 ## 环境搭建和编译 14 15 ### 环境配置 16 17 #### 搭建Ubuntu环境 18 19 - 初始环境软件安装（Ubuntu版本推荐18.04或20.04） 20 21 ``` 22 sudo apt-get update 23 sudo apt-get upgrade 24 sudo apt-get install git-lfs git bison flex gnupg build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses-dev x11proto-core-dev libx11-dev libc++1 lib32z1-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip m4 libtinfo5 bc npm genext2fs liblz4-tool libssl-dev ruby openjdk-8-jre-headless gdb python3-pip libelf-dev libxcursor-dev libxrandr-dev libxinerama-dev 25 ``` 26 27 详细Ubuntu安装搭建请参考 [搭建Ubuntu环境](https://developer.huawei.com/consumer/cn/training/course/video/C101639988048536240) 28 29 #### 源码获取 30 31 下载源码请参考 [下载说明](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/get-code/sourcecode-acquire.md) 32 33 ### 代码编译 34 35 注意：下列命令需在源码根目录下执行 36 37 1. 首次编译： 38 39 ``` 40 ./build.sh --product-name rk3568 41 ``` 42 2. 首次编译后增量编译方舟运行时： 43 44 编译linux-x86版本： 45 46 ``` 47 ./build.sh --product-name rk3568 --build-target ark_js_host_linux_tools_packages 48 ``` 49 50 编译oh-arm64版本： 51 52 ``` 53 ./build.sh --product-name rk3568 --gn-args use_musl=true --target-cpu arm64 --build-target ark_js_packages 54 ``` 55 56 编译oh-arm32版本: 57 58 ``` 59 ./build.sh --product-name rk3568 --build-target ark_js_packages 60 ``` 61 3. 首次编译后增量编译方舟前端： 62 63 ``` 64 ./build.sh --product-name rk3568 --build-target ets_frontend_build 65 ``` 66 67 更多编译命令请参考 [编译命令](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/subsystems/subsys-arkcompiler-guide.md) 68 69 **说明**：上述编译命令为release版本，编译debug版本需增加编译选项：--gn-args is_debug=true。 70 71 方舟相关的二进制文件在如下路径： 72 73 ``` 74 out/rk3568/arkcompiler/runtime_core/ 75 out/rk3568/arkcompiler/ets_frontend/ 76 out/rk3568/arkcompiler/ets_runtime/ 77 out/rk3568/clang_x64/arkcompiler/runtime_core/ 78 out/rk3568/clang_x64/arkcompiler/ets_frontend/ 79 out/rk3568/clang_x64/arkcompiler/ets_runtime 80 ``` 81 82 ## 开发实例 83 84 本章节将介绍基于方舟运行时的开发测试实例。 85 86 ### HelloWorld 87 88 #### 运行前准备 89 90 * 编译编译方舟运行时和方舟前端 91 92 ``` 93 ./build.sh --product-name rk3568 --build-target ark_js_host_linux_tools_packages --build-target ets_frontend_build 94 ``` 95 96 #### 运行hello-world.js 97 98 新建hello-world.js文件，写入以下源码： 99 100 ``` 101 print("Hello World!!!"); 102 ``` 103 104 运行步骤： 105 106 1. 通过方舟前端生成hello-world.abc文件，编译命令： 107 108 ``` 109 /your_code_path/out/rk3568/clang_x64/arkcompiler/ets_frontend/es2abc hello-world.js 110 ``` 111 112 2. 执行hello-world.abc文件： 113 114 1. 设置搜索路径： 115 116 ``` 117 export LD_LIBRARY_PATH=/your_code_path/out/rk3568/clang_x64/arkcompiler/ets_runtime:/your_code_path/prebuilts/clang/ohos/linux-x86_64/llvm/lib:/your_code_path/out/rk3568/clang_x64/thirdparty/zlib 118 ``` 119 2. 执行ark\_js\_vm： 120 121 ``` 122 /your_code_path/out/rk3568/clang_x64/arkcompiler/ets_runtime/ark_js_vm hello-world.abc 123 ``` 124 125 执行结果如下： 126 127 ``` 128 Hello World!!! 129 ``` 130 131 **说明**：此处“_your_code_path_”为源码目录路径。 132 133 #### 反汇编hello-world.abc 134 135 编译生成反汇编工具： 136 137 ``` 138 ./build.sh --product-name rk3568 --build-target arkcompiler/runtime_core:ark_host_linux_tools_packages 139 ``` 140 141 执行如下命令，结果输出到output.pa文件中： 142 143 ``` 144 /your_code_path/out/rk3568/clang_x64/arkcompiler/runtime_core/ark_disasm hello-world.abc output.pa 145 ``` 146 147 hello-world.abc反汇编结果如下： 148 149 ``` 150 # 151 # source binary: hello-world.abc 152 # 153 154 # ==================== 155 # LITERALS 156 157 # ==================== 158 # RECORDS 159 160 .record _ESAnnotation <external> 161 162 .record _ESModuleMode { 163 u8 isModule 164 } 165 166 # ==================== 167 # METHODS 168 169 .function any func_main_0_any_any_any_any_(any a0, any a1, any a2) <static> { 170 mov v2, a2 171 mov v1, a1 172 mov v0, a0 173 builtin.acc 174 sta v5 175 builtin.idi "print", 0x0 // 加载print函数 176 sta v3 177 lda.str "Hello World!!!" // 加载Hello World!!!字符串 178 sta v4 179 builtin.tern3 v3, v4 // 调用print函数 180 builtin.acc 181 } 182 ``` 183 184 ### 运行Test262测试用例 185 186 #### 运行前准备 187 188 1. 编译方舟运行时，编译命令： 189 190 ``` 191 ./build.sh --product-name rk3568 --build-target ark_js_host_linux_tools_packages 192 ``` 193 194 2. 编译方舟前端，编译命令： 195 196 ``` 197 ./build.sh --product-name rk3568 --build-target ets_frontend_build 198 ``` 199 200 **说明**：编译命令执行路径为项目根目录。 201 202 #### 运行Test262 203 204 运行run\_test262.py脚本，下载及运行Test262用例。 205 206 命令行格式： 207 208 ``` 209 python3 test262/run_test262.py [options] 210 ``` 211 212

ark_js_host_linux_tools_packages --build-target arkcompiler/runtime_core:ark_host_linux_tools_packages 379 ``` 380 381 * 新建hello-world.ts文件，写入以下源码： 382 383 ``` 384 declare function print(arg:any):string; 385 print('Hello World!!!') 386 ``` 387 388 #### 运行步骤 389 390 1. 通过方舟前端生成hello-world.abc文件，编译命令： 391 392 ``` 393 /your_code_path/out/rk3568/clang_x64/arkcompiler/ets_frontend/es2abc --module --type-extractor --merge-abc hello-world.ts 394 ``` 395 2. 设置搜索路径： 396 397 ``` 398 export LD_LIBRARY_PATH=/your_code_path/out/rk3568/clang_x64/arkcompiler/ets_runtime:/your_code_path/prebuilts/clang/ohos/linux-x86_64/llvm/lib:/your_code_path/out/rk3568/clang_x64/thirdparty/icu:/your_code_path/out/rk3568/clang_x64/thirdparty/zlib 399 ``` 400 3. 运行ark\_js\_vm，采集PGO信息，生成的PGO信息落盘在文件hello-world.ap： 401 ``` 402 /your_code_path/out/rk3568/clang_x64/arkcompiler/ets_runtime/ark_js_vm --enable-pgo-profiler=true --compiler-pgo-profiler-path=hello-world.ap --entry-point=hello-world hello-world.abc 403 ``` 404 4. 通过AOT编译器生成an和ai文件，可以通过info日志观察到被编译的函数列表： 405 406 ``` 407 /your_code_path/out/rk3568/clang_x64/arkcompiler/ets_runtime/ark_aot_compiler --enable-pgo-profiler=true --compiler-pgo-profiler-path=hello-world.ap --log-level=info --aot-file=./hello-world hello-world.abc 408 ``` 409 5. 执行ark\_js\_vm： 410 411 ``` 412 /your_code_path/out/rk3568/clang_x64/arkcompiler/ets_runtime/ark_js_vm --aot-file=./hello-world --entry-point=hello-world hello-world.abc 413 ``` 414 415 执行结果如下： 416 417 ``` 418 Hello World!!! 419 ``` 420 421 **说明**：此处“_your_code_path_”为源码目录路径。 422 423 ## 工具链使用 424 425 方舟前端工具采用命令行交互方式，支持将ArkTS代码转换为方舟字节码，使其能够在方舟运行时上运行。支持Windows/Linux/Mac平台。 426 427 ### ArkTS字节码编译工具概述 428 429 使用前端工具将ArkTS文件转换为方舟字节码文件。方舟前端工具在linux平台上可通过全量编译或指定编译前端工具链获取。 430 431 构建编译： 432 433 ``` 434 $ ./build.sh --product-name rk3568 --build-target ets_frontend_build 435 ``` 436 437 ``` 438 $ cd out/rk3568/clang_x64/arkcompiler/ets_frontend/ 439 $ ./es2abc [options] file.js 440 ``` 441 442 <a

rk3568 --build-target ark_js_host_linux_tools_packages 651 ``` 652 653 命令行格式： 654 655 ``` 656 ark_aot_compiler [选项] 输入文件 657 ``` 658 659 | 选项 | 描述 | 660 | ----------------------- | ----------------------------------------------------------------------------------- | 661 | --aot-file | AOT输出文件的路径（不需要文件后缀）。默认值：“aot_file” | 662 | --compiler-opt-type-lowering | 利用类型信息，生成优化级别更高的机器码。默认值：“true” | 663 | --compiler-opt-max-method | 设置AOT编译方法的大小阈值，当方法的大小超过该值时，则不进行编译。默认值：“32KB” | 664 | --compiler-opt-level | 设置AOT的优化级别。默认值：“3” | 665 | --compiler-log | AOT的日志选项，可打印出AOT生成的IR图、汇编码等信息。默认值“none” | 666 | --compiler-log-snapshot | 打印与序列化有关的日志信息。默认值“false” | 667 | --compiler-log-time | 打印AOT过程中各个优化pass的耗时情况。默认值值“false” | 668 669 670 输入文件：二进制格式的方舟字节码 671 672 输出文件：直接执行的机器码的an文件、存储序列化后ConstPool的ai文件（输出文件路径需使用--aot-file选项指定） 673 674 ### PGO工具概述 675 676 PGO为Profile-guided optimization的简称，也即配置文件引导的优化。该工具能够记录应用启动和性能场景中的高频（热点）函数，并将信息记录于对应的PGO Profiler文件。AOT编译器则可通过这些信息决策部分函数进行编译，从而在基本不影响应用运行性能的情况下，缩短编译时间，减少.an文件的大小。 677 678 编译生成aot编译器和ark js虚拟机 679 680 ``` 681 ./build.sh --product-name rk3568 --build-target ark_js_host_linux_tools_packages 682 ``` 683 684 ### 生成PGO Profiler文件 685 686 命令行格式： 687 688 ``` 689 ark_js_vm [选项] 输入文件 690 ``` 691 692 | 选项 | 描述 | 693 | ----------------------- |

profiler文件的保存路径。默认值："none" | 696 | --compiler-pgo-hotness-threshold | 热点函数的阈值，当函数的调用次数大于该值，则认为是热点函数。默认值：“2” | 697 698 输入文件：二进制格式的方舟字节码 699 700 输出文件：保存有热点函数信息的ap文件 701 702 ### 基于PGO Profiler的AOT编译 703

输出文件：直接执行的机器码的an文件（基于pgo） 717
