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 ...

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... (Lire plus)

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... (Lire plus)

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... (Lire plus)

In some discussions among OCaml developers around the empty type (PR#9459), some people mused about the possibility of annotating functions with an attribute telling the compiler that the function should be trivial, and always return a value strictly equivalent to its argument.Curious about the feas...

Au cours de discussions parmi les développeurs OCaml sur le type vide (PR#9459), certains caressaient l’idée d’annoter des fonctions avec un attribut indiquant au compilateur que la fonction devrait être triviale, et toujours renvoyer une valeur strictement équivalente à son argument. Nous ... (Lire plus)

Nous sommes heureux de présenter certains travaux en cours sur le compilateur OCaml, travaux menés en étroite collaboration avec notre partenaire et client Janestreet. Un travail conséquent a été fait pour aboutir à un nouveau framework d’optimisation du compilateur, appelé Flambda2, dont ... (Lire plus)

The OCaml compiler team at OCamlPro is happy to present some of the work recently done jointly with JaneStreet's team. A lot of work has been done towards a new framework for optimizations in the compiler, called Flambda2, aiming at solving the shortcomings that became apparent in the Flambda optimi... (Lire plus)

As announced some time ago, I am working on a new intermediate language within the OCaml compiler to improve its inlining strategy. After some time of bug squashing, I prepared a testable version of the patchset, available either on Github (branch flambda_experiments), or through OPAM, in the follow... (Lire plus)

Doing the compiler's work Working at OCamlPro may have some drawbacks. I spend a lot of time hacking the OCaml compiler. Hence when I write some code, I have a good glimpse of what the generated assembly will look like. This is nice when I want to write performance sensitive code, but as I usually w... (Lire plus)
