Swift Might Not Be As Fast As Apple Claims It To Be: First Benchmarks

by Sergio De Simone on  Jun 11, 2014

Performance is one of the benefits that Apple claims its new Swift programming language should bring to OS X and iOS developers, and being in beta hasn't prevented independent developers from running benchmarks and reporting their findings. Perhaps unsurprisingly these show that in some cases Swift performance is not yet satisfactory.

Apple Releases Swift, a High-performance High-level Language for iOS and OSX

by Alex Blewitt on  Jun 03, 2014 6

Today at WWDC 2014, Apple announced the beta availability of a new programming language, swift, which is set to ship with iOS 8 and OSX Yosemite later this year. Swift is a high-level programming language that will be familiar to JavaScript developers, but is compiled using LLVM to produce highly performant executable code for both OSX and iOS platforms.

FreeBSD 10 Alpha Built With clang

by Alex Blewitt on  Sep 16, 2013

FreeBSD 10 has had its first alpha release, bringing with it a long planned for change to switch to the Clang compiler instead of GCC on platforms where it is available. It is also the first FreeBSD release to run on the Raspberry Pi. Read on to find out more about the decision to switch compilers, and what it means for users.

Debate: Do We Need a Universal Web Bytecode?

by Abel Avram on  May 22, 2013 11

Is a universal web bytecode worth the trouble creating it? Is LLVM the solution? Which is better at running native code in the browser: Mozilla asm.js or Google PNaCl? This article contains opinions expressed on the web on these issues.

LLVM Proposes Adding Modules to C

by Alex Blewitt on  Nov 30, 2012

At the November LLVM developers meeting, Doug Gregor of Apple gave a presentation on adding modules to C. This provides a transitional approach to providing modules as a means to both speed up compilation time and to improve the amount of semantic information provided by libraries, which can be used to improve both IDEs and debugging.

Automatic Reference Counting in Objective-C

by Alex Blewitt on  Jun 16, 2011 3

A document has appeared on the Clang website describing requirements for Automatic Reference Counting in Objective-C. This provides a service, akin to C++'s auto, which allows objects to automatically take part in the retain/release/autorelease cycle without requiring the user to do anything explicitly about it.

The Last Flight of the Unladen Swallow

by Alex Blewitt on  Mar 30, 2011

Unladen Swallow was an attempt to bring LLVM optimisations to the CPython runtime, but hasn't seen significant activity for the last year. Now, a Unladen swallow retrospective confirms that the project is defunct and is no longer being developed. What happened?

Languages Come to Javascript VMs: CoffeeScript 1.0, StratifiedJS, C/C++ with Emscripten, Python

by Werner Schuster on  Dec 25, 2010 7

Javascript's ubiquity and increasingly fast VMs have made it an interesting runtime for languages. InfoQ looks at languages and tools that compile to Javascript: CoffeeScript 1.0, StratifiedJS, the Emscripten LLVM backend which brings C/C++ to Javascript, and more.

LLVM 2.8 Released

by Alex Blewitt on  Oct 07, 2010 1

The LLVM team yesterday released LLVM 2.8, the low-level virtual machine infrastructure that includes a next-generation C/C++ compiler, optimiser, and run-time. In addition, the LLVM also sports a VMKit for CLR and JVM runtime and is used in tools as diverse as MacRuby and Python's Unladen Swallow. Additionally, the recently-released Mono 2.8 has a mono-llvm runtime. So what's new in LLVM 2.8?
