Compiling Scala to LLVM

This is the paper presented at the Second Scala Workshop to be held at Stanford on June 2nd 2011.

Abstract

This paper describes ongoing work to implement a new backend for the Scala compiler that targets the Low Level Virtual Machine (LLVM). LLVM aims to provide a universal intermediate representation for compilers to target and a framework for program transformations and analyses. LLVM also provides facilities for ahead-of-time and just-in-time native code generation. Targeting LLVM allows us to take advantage of this framework to compile Scala source code to optimized native executables. We discuss the design and implementation of our backend. We also outline the additional work needed to produce a robust backend.
