26. LLVM

27. 아이디어의 시작은…
• JVMs do all optimizations online at JIT time:
- Hugely redundant across runs
- Applications launch slowly
- What if we could do heavy lifting at install time?
!
• Problem: Java bytecode is too limiting!
- Memory safety prevents some optzns (eg. bounds checks)
- JVM type system doesn’t lend itself to machine optzns

28. With some sort of low level virtual machine,
we could optimize better and a JIT compiler
would have to do less work online!

29. Introduction
• LLVM
- Low-Level Virtual Machine
• An Infrastructure for Multi-stage Optimization
- by Chris Arthur Lattner @2002
• Design and Implementation of a compiler infrastructure
- support a unique multi-stage optimization system
- support inter-procedural and profile-driven optimizations
• LLVM virtual instruction (IR)
- with high-level type information
• Sponsored by APPLE

33. LLVM use in Open Source OSes
• Minix moved to Clang as default compiler
• FreeBSD is working on ClangBSD
• LLVM is the basis of the Renderscript
compiler in Android
• LLVM a hard dependency for Gallium3D
• Building Debian with Clang
• Unsupported GCC Flags / C Extensions

34. Use-case #1 - New Compiler
• Cling - CERN
• CtoVerilog - Haifa University
• OpenCL - AMD
• Click - Ericsson
• EDGtoLLVM - ARM
• Jaguar - Cray
• Delphi XE- Embarcadero

35. Use-case #2 - Optimization
Flash ActionScript (.as3)
➔ ActionScript Bytecode (.abc)
➔ LLVM Bytecode (.bc)
➔.abc ➔ .swf

36. Use-case #3 - Cross Language
Crack Scripting Language
➔ C/C++/Java-like Scripting Language
➔ Speed of a compiled language,
ease of use of a scripting language
➔ Unladen Sparrow(Python), Rubinius(Ruby), V8(JS)
cf. PNaCl (Portable Native Client)

37. Use-case #3 - Emscripten
compiles LLVM bytecode into JavaScript
➔ C/C++ to JavaScript
➔ can be run on the web
➔ Python, the Bullet physics engine, eSpeak (TTS)
https://github.com/kripken/emscripten/wiki
Everything compiles into LLVM bitcode
The web is everywhere, and runs JavaScript
Compiling LLVM bitcode to JavaScript lets us run
~ everything, everywhere

41. Continuous Integration
• 여러 버전의 OS와 하드웨어 모델별로 테스트
• 프로젝트의 빌드, 분석, 테스트를 자주
• 자동으로 빠르게 문제를 파악하고
• 과도한 작업은 서버로 이관
• 프로젝트의 빌드/테스트 이력을 보관
• 개발팀 분산 작업에 도움
cf. Jenkins, Hudson, CruiseControl
