macOS 下如何编译 hsdis

要顺利使用 Java 的 "-XX:+PrintAssembly" 参数，需要手动编译（其实下载也行）和安装 "hsdis-amd64.dylib" 到本地系统。

编译 hsdis

git clone https://github.com/openjdk/jdk.git
cd jdk/src/utils/hsdis

# 下载 binutils: https://ftp.gnu.org/gnu/binutils/
wget https://ftp.gnu.org/gnu/binutils/binutils-2.35.1.tar.xz
tar -xf binutils-2.35.1.tar.xz

make BINUTILS=binutils-2.35.1 ARCH=amd64

如果一切顺利，构建产物位于 build/macosx-amd64/hsdis-amd64.dylib

安装

安装非常简单，只需要把 hsdis-amd64.dylib 拷贝到对应的目录。

# Java 8
sudo cp build/macosx-amd64/hsdis-amd64.dylib /Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home/jre/lib/server/

# Java 9 or higher
sudo cp build/macosx-amd64/hsdis-amd64.dylib /Library/Java/JavaVirtualMachines/jdk-9.0.4.jdk/Contents/Home/lib/server/

# If you install JDK via Sdkman
cp build/macosx-amd64/hsdis-amd64.dylib ~/.sdkman/candidates/java/11.0.9-zulu/zulu-11.jdk/Contents/Home/lib
