The GHC reading list
Suppose you want to start contributing to GHC: what should you read by way of background? Here is an annotated list. Please add to it as you come across useful material.
- The GHC Commentary is a Wiki that describes GHC's implementation. It is a Wiki. That means that you can, and should, fix errors and write new chapters.
- The Glasgow Haskell Compiler, in The Architecture of Open Source Applications, Volume II, ed Brown & Wilson. This paper gives an up to date (2012) technical overview of GHC.
- Simon PJ's home page and publications page have lots of relevant papers. Some key ones appear below but not all.
- Simon PJ's books:
- The Implementation of Functional Programming Languages
- Implementing Functional Languages: a tutorial give useful general background. They are not GHC-specific at all, but they have lots of information about functional-language compilers.
Types and type inference
- Modular type inference with local assumptions, Simon Peyton Jones, Dimitrios Vytiniotis, Tom Schrijvers, Martin Suzmann, Journal of Functional Programming, 2011. This epic 83-page JFP paper brings together, in a single uniform framework, a series of our earlier papers on type inference for type systems involving local constraints, including GADTs and indexed type families.
- Papers about type equalities in GHC's intermediate language
- Equality proofs and deferred type errors, Simon Peyton Jones, Dimitrios Vytiniotis and Pedro Magalhaes (ICFP 2012). An exploration of what happens when you take equality proofs seriously in a compiler.
- Giving Haskell a promotion, Brent Yorgey, Stepanie Weirich, Julien Cretin, Simon Peyton Jones, and Dimitrios Vytiniotis (TLDI 2012). How to (a) add kind polymorphism and (b) promote data types to become data kinds.
- System F with Type Equality Coercions, Martin Sulzmann, Manuel Chakravarty, and Simon Peyton Jones (TLDI 2007). The first paper about System FC.
- Unboxed values as first class citizens, SL Peyton Jones and J Launchbury, Functional Programming Languages and Computer Architecture (FPCA'91), Boston, LNCS 523, Springer Verlag, Sept 1991, pp636-666. How unboxed data types work in GHC.
Please add: System FC, GADTs, kind polymorphism etc
- A transformation-based optimiser for Haskell, SL Peyton Jones and A Santos, Science of Computer Programming 32(1-3), pp3-47, September 1998. Gives an overview of many of the transformations GHC does on Core. Andre's PhD thesis gives more details.
- Secrets of the GHC inliner, Simon Peyton Jones and Simon Marlow, Journal of Functional Programming 12(4), July 2002, pp393-434. Describes how the Simplifier does inlining.
- A short cut to deforestation, A Gill, SL Peyton Jones, J Launchbury, Proc Functional Programming Languages and Computer Architecture (FPCA'93), Copenhagen, June 1993, pp223-232. The famous foldr/build rule. Andy's PhD thesis has more.
- Playing by the rules: rewriting as a practical optimisation technique in GHC, Simon Peyton Jones, Andrew Tolmach and Tony Hoare, Haskell Workshop 2001. Describes how RULES work, which are heavily used in GHC.
Back end issues
- How to make a fast curry: push/enter vs eval/apply, Simon Marlow and Simon Peyton Jones, International Conference on Functional Programming, Snowbird, Sept 2004, pp4-15.
- Implementing lazy functional languages on stock hardware: the Spineless Tagless G-machine, SL Peyton Jones, Journal of Functional Programming 2(2), Apr 1992, pp127-202. The original STG paper but still highly relevant.
