After 5 years of work, I'm proud to announce Shed Skin 0.3, an experimental (but obviously restricted) Python-to-C++ compiler. Looking over the release notes, I'm convinced this must be the best release so far. I would like to thank especially Jeremie Roquet, for several major contributions to this release, and Thomas Spura, for reorganizing the codebase. Joris van Rantwijk provided the great new
Eric Lippert's Erstwhile Blog Why is deriving a public class from an internal class illegal? In C# it is illegal to declare a class D whose base class B is in any way less accessible than D.... Author: Eric Lippert Date: 11/13/2012 It's still essential! I am pleased to announce that Essential C# 5.0 by Mark Michaelis, and, new for this edition, yours...

Abdulaziz Ghuloum (Indiana University), An Incremental Approach to Compiler Construction Compilers are perceived to be magical artifacts, carefully crafted by the wizards, and unfathomable by the mere mortals. Books on compilers are better described as wizard-talk: written by and for a clique of all-knowing practitioners. Real-life compilers are too complex to serve as an educational tool. And the
Welcome to pcc, the Portable C Compiler. This website is a wiki. Please join and help improve the website and pcc. The compiler is based on the original Portable C Compiler by S. C. Johnson, written in the late 70's. About 50% of the frontend code and 80% of the backend code has been modified. See the PCC History wiki page for details. PCC 1.1.0 is out as of 2014-12-10!

Since its creation, the C language has been tightly tied to UNIX. C was designed as a portable assembly language for reimplementing UNIX, to make it easier to port to different platforms. In 1984, Richard Stallman began the GNU (GNUâs Not UNIX) Project to provide a clone of the UNIX operating system using entirely Free Software. Because a C compiler is a core component of any UNIX-like operating s

When: October 2, 2009 SPONSORED BY: Apple, Google, Adobe, Qualcomm Incorporated The meeting serves as a forum for both LLVM and Clang developers and users to get acquainted, lea rn how LLVM is used, and exchange ideas about LLVM and its (potential) applications.

News [Note: I am no longer working on TCC. Check the mailing list to get up to date information.] Features SMALL! You can compile and execute C code everywhere, for example on rescue disks (about 100KB for x86 TCC executable, including C preprocessor, C compiler, assembler and linker). FAST! tcc generates x86 code. No byte code overhead. Compile, assemble and link several times faster than GCC. UN
Introduction GNU C (and some other compilers) had inline functions long before standard C introduced them (in the 1999 standard); this page summarizes the rules they use, and makes some suggestions as to how to actually use inline functions. The point of making a function inline is to hint to the compiler that it is worth making some form of extra effort to call the function faster than it would o
Polymorphic inline caching is a technique to speed up method dispatch by generating custom code at method call sites that checks the receiver against only those classes that have come up at that call site. If the receiver's class does not appear in the polymorphic inline cache (this case is known as a "cache miss"), then a new call stub is generated, which checks the receiver's class in addition t
(To follow my compiler related posts, either subscribe to my main RSS feed, or the compiler specific one ) Back in March 2008 I started publishing a series on how to write a compiler in Ruby, bottom up, that is, starting with the code generator and working my way up instead of the more traditional approach of writing the parser first. Here are the parts I've published on my blog so far. (The bits
Overview Nanojit is a small, cross-platform C++ library that emits machine code. Both the Tamarin JIT and the SpiderMonkey JIT (a.k.a. TraceMonkey) use Nanojit as their back end. You can get Nanojit by cloning the tamarin-redux Mercurial repository at http://hg.mozilla.org/tamarin-redux. It's in the nanojit directory. The input for Nanojit is a stream of Nanojit LIR instructions. The term LIR is c

In computer science, an operator-precedence parser is a bottom-up parser that interprets an operator-precedence grammar. For example, most calculators use operator-precedence parsers to convert from the human-readable infix notation relying on order of operations to a format that is optimized for evaluation such as Reverse Polish notation (RPN). Edsger Dijkstra's shunting yard algorithm is commonl
