Compilers and Virtual Machines

Igalia is the most experienced JavaScript virtual machine engineering consultancy contributing code upstream to V8, JavaScriptCore and SpiderMonkey. We also apply our compilers knowledge to work in other dynamic language implementations like Python, Scheme, Ruby and more.

Compiler technology is at the heart of performance optimization: compilers generate the machine code that will run your software, and as such, they are the main responsible actors in making the best use of the CPU instruction set to get the job done in the most efficient way possible.

We have the best team of WebKit developers with a strong competence in JavaScript engines like V8, JavaScriptCore and SpiderMonkey, making Igalia the best partner of choice for optimizing consumer electronic solutions based on client-side web technology.

We specialize in JavaScript upstream work as well as other domains such as debuggers (GDB and integrated debuggers), dynamic language environments integration to existing C/C++ systems, and Guile Scheme compiler, especially in the optimizer and its next-generation virtual machine.

Igalia has talented engineers who understand how compilers work and can optimize how they generate machine code for your programs, providing that performance boost that can make a real difference. Our team can provide holistic optimizations: in the runtime, on the frontend, the optimizer and in the backend.

We can also help companies developing Javascript-based software and products, advising on their design and implementation choices or programming and upstreaming new features required in the javascript engine.

Awaiting the future of JavaScript in V8

On the evening of Monday, May 16th, 2016, we have made history. We’ve landed the initial implementation of “Async Functions” in V8, the JavaScript runtime in use by the Google Chrome and Node.js. We do these things not because they...

a lambda is not (necessarily) a closure

prefaceGreets, folks! Check it out: Guile had a whole track devoted to it at FOSDEM this year. OK, so it was only half a day, but there were like a dozen talks! And the room was full all the morning! And -- get this -- I had nothing to do with its...

guile compiler tasks

Hey! We released Guile 2.1.2, including the unboxing work, and we fixed the slow bootstrap problem by shipping pre-built bootstraps in tarballs. A pretty OK solution in my opinion; check it out!future workAt this point I think I'm happy with...

talks i would like to give in 2016

Every year I feel like I'm trailing things in a way: I hear of an amazing conference with fab speakers, but only after the call for submissions had closed. Or I see an event with exactly the attendees I'd like to schmooze with, but I...

unboxing in guile

Happy snowy Tuesday, hackfolk! I know I said in my last dispatch that I'd write about Lua soon, but that article is still cooking. In the meantime, a note on Guile and unboxing.on boxen, on blitzenBoxing is a way for a programming language...
