各位同学:
JIT (Just-In-Time) 编译技术在现代编程语言中的运用十分广泛。我们使用的众多主流语言,包括
Java、JavaScript、C#、Python、Lua 等,都通过 JIT 技术实现了数倍至数百倍的性能提升。了解 JIT
的原理,有助于更精准地优化上层应用的性能。
内容:
- JIT 简介
- 例子:min-wasm - 代码生成基础 (x86-64)
- Stackmap: IR 机器状态与目标架构机器状态的映射
- 垃圾收集、机器代码替换 (On-Stack Replacement)
- 运行时特化
- (Meta-)tracing/partial evaluation, 解释器循环的自动展开
- JVM, CLR, V8, pypy - 常见 JIT 运行环境对比分析
时间:5 月 25 日(周六)晚 19:30 - 21:00
地点:江宁校区一号楼六楼IT创新区会议室
讲者:周鹤洋
