We are excited to announce the release of Alt-Ergo 2.6! Alt-Ergo is an open-source automated prover used for formal verification in software development. It is part of the arsenal behind static analysis frameworks such as TrustInSoft Analyzer and Frama-C, and is one of the solvers behind Why3, a pla... (Read more)

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... (Read more)

In this post, I will present some work that we did on the GnuCOBOL compiler, the only fully-mature open-source compiler for COBOL. It all started with a bug issued by one of our customers that we fixed by improving the preprocessing pass of the compiler. We later went on and optimised it to get bett... (Read more)

Uncaught exception: Not_found This blog post probably won't teach anything new to OCaml veterans; but for the others, you might be glad to learn that this very basic, yet surprisingly little-known feature of OCaml will give you backtraces with source file positions on any uncaught exception. Since i... (Read more)

Welcome, dear reader, to a new opam blog post! Today we take an additional step down the metaphorical rabbit hole with opam pin, the easiest way to catch a ride on the development version of a package in opam. We are aware that our readers are eager to see these blog posts venture on the developer s... (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)

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)

Monitoring Edge Technical Endeavours As a company specialized in strongly-typed programming languages with strong static guarantees, OCamlPro closely monitors the ongoing trend of bringing more and more of these elements into mainstream programming languages. Rust is a relatively recent example of t... (Read more)
