Maple 编译器和引擎

输入图片说明

Linux服务器环境设置

需要一台Linux x86_64服务器,至少16GB或以上内存,安装Ubuntu 16.04或18.04系统. 若您的服务器只有16GB内存,需要创建8GB或以上的swap空间。

编译和链接 OpenJDK 核心库时,会占用很多内存。对于少于16GB内存的服务器,可以考虑 在其它内存较多的服务器上先构建好libcore.so, 将maple_engine/maple_build/out/这个 目录打包传到您的本地机器,展开后放到本地机器 同名目录下,再拷贝其中的文件 libcore.so 到maple_engine/maple_runtime/lib/x86_64/libcore.so,就可以本地编译和运行应用程序了。

登录服务器后,执行如下命令安装所需的软件包:

    sudo apt install -y build-essential clang cmake libffi-dev libelf-dev libunwind-dev \
            libssl-dev openjdk-8-jdk-headless unzip python-minimal python3 gdb bc highlight

Maple 构建环境设置

下载代码并设置Maple 构建环境:

  git clone https://gitee.com/openarkcompiler-incubator/maple_engine.git
  cd maple_engine
  source ./envsetup.sh

若要执行后续命令,需先执行source ./envsetup.sh.

构建Maple 编译器和Maple引擎

  ./maple_build/tools/build-maple.sh

构建Java 核心库

按照文档./maple_build/doc/build_OpenJDK8.md 中介绍的方法构建定制的OpenJDK-8. 将文档中提到的必需的.jar 文件拷贝到./maple_build/jar/ 目录中,再执行如下命令:

   ./maple_build/tools/build-libcore.sh

构建Java 核心库完成后,会将编译应用代码所需要的文件拷贝到maple_runtime/lib/x86_64/目录下。

编译和执行应用程序

以HelloWorld为例,编译和执行一个应用程序:

  cd ./maple_build/examples/HelloWorld
  "$MAPLE_BUILD_TOOLS"/java2asm.sh HelloWorld.java
  "$MAPLE_BUILD_TOOLS"/asm2so.sh HelloWorld.s

  "$MAPLE_BUILD_TOOLS"/run-app.sh -classpath ./HelloWorld.so HelloWorld

调试应用程序

  "$MAPLE_BUILD_TOOLS"/run-app.sh -gdb -classpath ./HelloWorld.so HelloWorld

Build envionment setup

Needs a Linux x86_64 server with 16GB or more RAM and Ubuntu 16.04/18.04 installed. If your server has 16GB RAM, please setup 8GB or more swap space.

Execute the following command to install the packages used by the Maple build.

sudo apt install -y build-essential clang cmake libffi-dev libelf-dev libunwind-dev \
        libssl-dev openjdk-8-jdk-headless unzip python-minimal python3 gdb bc highlight

Setup Maple environment

  cd maple_engine
  source ./envsetup.sh

Build Maple compiler and engine

  ./maple_build/tools/build-maple.sh

Build Java core library

Following the doc at ./maple_build/doc/build_OpenJDK8.md to build the customized OpenJDK8. Make sure the needed .jar files are copied into ./maple_build/jar/ directory.

   ./maple_build/tools/build-libcore.sh

Build and run app

  cd ./maple_build/examples/HelloWorld
  "$MAPLE_BUILD_TOOLS"/java2asm.sh HelloWorld.java
  "$MAPLE_BUILD_TOOLS"/asm2so.sh HelloWorld.s

  "$MAPLE_BUILD_TOOLS"/run-app.sh -classpath ./HelloWorld.so HelloWorld

Debug app with Maple debugger

  "$MAPLE_BUILD_TOOLS"/run-app.sh -gdb -classpath ./HelloWorld.so HelloWorld
