Welcome to a new episode of The Flambda2 Snippets! The F2S blog posts aim at gradually introducing the world to the inner-workings of a complex piece of software engineering: The Flambda2 Optimising Compiler for OCaml, a technical marvel born from a 10 year-long effort in Research & Development and ...

Flambda2 Ep. 2: Loopifying Tail-Recursive Functions

Authors: Nathanaëlle Courant, Guillaume Bury, Pierre Chambart, Vincent Laviron, Dario Pinto
Date: 2024-05-07
Category: OCaml
Tags: Flambda, Flambda2, loopify, optimisation, f2s, ep2, loopify, tailcall, tail-recursion

Welcome to a new episode of The Flambda2 Snippets! Today's topic is Loopify, one of Flambda2's many optimisation algorithms which specifically deals with optimising both purely tail-recursive and/or functions annotated with the [@@loop] attribute in OCaml. A lazy explanation for its utility would be... (Read more)

Welcome to The Flambda2 Snippets! In this first post of The Flambda2 Snippets, we dive into the powerful CPS-based internal representation used within the Flambda2 optimizer, which was one of the main motivation to move on from the former Flambda optimizer. Credit goes to Andrew Kennedy's paper Comp... (Read more)

Behind the Scenes of the OCaml Optimising Compiler Flambda2: Introduction and Roadmap

Introducing our Flambda2 snippets At OCamlPro, the main ongoing task on the OCaml Compiler is to improve the high-level optimisation. This is something that we have been doing for quite some time now. Indeed, we are the authors behind the Flambda optimisation pass and today we would like to introduc... (Read more)
