Compilers

For most of their lifetimes, C# and VB.NET have evolved at their own pace and in their own ways (C# added iterators, VB.NET didn't. VB.NET added XML Literals, C# didn't. etc, etc...). Today, Luca Bolognese and team have embarked on a new approach to how .NET's premiere languages will evolve going…

The VC++ 2012 auto-vectorizer tries to make loops in your code run faster by automatically vectorizing your code using the SSE instructions available in all current mainline Intel and AMD chips. In Visual C++ 2012, auto-vectorization is on by default and requires only that you…

In this installment of GoingNative, it's all about the latest C++ compiler technology from Microsoft. Most of the time is spent discussing VC11's Auto-Vectorizer with a few short forays into other VC compiler improvements (like Auto-Parallelizer). You meet the lead developer for VC11's…

Dynamics Program Manager Peter Villadsen and Software Developer Gustavo Plancarte teach us about a new tool they've developed that translates X++ byte code into MSIL. We learn a lot of history along the way and gain insights into the process of taking X++ into the .NET…

Happy Birthday, Channel 9!!! We are 7 years old today! Hard to believe... What a great 7 years it has been. THANK YOU, NINERS! In celebration, we bring you the latest episode of Checking In with Erik Meijer. Our very special guest is Eric Lippert. To Erik, thank you for some many years of great…

Ever wonder what really happens when you write a simple LINQ query? A lot of new language features went into the compilers in Visual Studio 2008 to make LINQ work. In this interview I sit down with Jonathan Aneja, a Program Manager on the Visual Basic Compiler team, who dives deep into these…

What is Roslyn? Traditionally, compilers are black boxes – source code goes in one end and object files or assemblies come out the other end. The Roslyn project changes that model by opening up the Visual Basic and C# compilers as APIs. These APIs allow tools and end-users to share in the wealth of…

Multicore JIT is a .NET 4.5 compiler technology that uses parallelization to reduce the JIT compilation time during application startup.Multicore JIT team says: "With Multicore JIT, methods are compiled on two cores in parallel. The more code you execute on your startup path, the more…

The IE9 Platform Preview includes the first release of the new JavaScript engine. This new engine compiles JavaScript source code into high-quality native machine code. It also has a new fast interpreter for sequentially executing script on traditional web pages and contains…

Profile Guided Optimization, or PGO, is an approach to optimization where the compiler uses profile information to make better optimization decisions for the program.  Profiling is the process of gathering information of how the program is used during runtime.  In a nutshell, PGO is…
