Version 2.6 of LLVM, the Low-Level Virtual Machine, has been released.

CodeSourcery has updated its commercially supported GNU- and Eclipse-based software development toolkits with compiler optimizations and other enhancements. The Spring release of Sourcery G++ also offers a QEMU emulator and updated runtime library routines, as well as new IDE debugging support, says the company.

"The GCC development team have announced the availability of a first release candidate for version 4.4 of their GNU Compiler Collection..."

The Linux® kernel uses several special capabilities of the GNU Compiler Collection (GCC) suite. These capabilities range from giving you shortcuts and simplifications to providing the compiler with hints for optimization. Discover some of these special GCC features and learn how to use them in the Linux kernel.

What is Post-Link Optimization for Linux on POWER? Post-Link Optimization for Linux® on POWER™, also known as FDPR-Pro, is a performance-tuning utility used to improve the execution time and the real memory utilization of user-level application programs, based on their run-time profiles.

"The GCC team has released Version 4.3.0 of its GNU Compiler Collection. [...] The C++ standard library (libstdc++) has been given new classes for parallel data processing [...] The developers have also incorporated parts of the future ISO C++ standard..."

Last week GCC 4.5.0 entered the world with improvements. Over the weekend we decided to benchmark this major update to the GNU Compiler Collection to see how its performance compares to that of GCC 4.3 and 4.4.

"Friends, neighbors, &c: ahem! May I present a new compiler! ... Check out and build the vm branch of the Guile repository: [...] The pleasant thing about all this is that it's a small group of people, and that one individual working hard and working smart can make an enormous difference. So come along and play out those compiler optimization fantasies that you've been keeping secret!"

In the last few years, the GNU Compiler Collection (GCC) has undergone a major transition from GCC version 3 to version 4. With GCC 4 comes a new optimization framework (and new intermediate code representation), new target and language support, and a variety of new attributes and options.
