MilePost Compiler: AI optimises machine code

As part of the MilePost (Machine Learning for Embedded Programs Optimisation) 
project funded by Information Society Technologies (IST) of the European 
Union, the IBM research lab in Haifa, Israel, has released an open source 
compiler which automatically learns how to translate source code into machine 
code suitable for the respective hardware used. The compiler uses suggestions 
made by an ICI (Interactive Compilation Interface) plug-in.

IBM offers open source machine learning compiler

Called Milepost GCC, the compiler is the result of a collaboration between 
IBM and partners in the European Union-funded Milepost consortium. The 
project is an extension of the GCC (GNU Compiler Collection) effort.

GCC 4.4 improves open source compiler with Graphite

What does that all mean?
Well it means that (some) programs that are compiled with GCC (and that's a lot) will now benefit from the improved optimizations and could possibly as a result become faster themselves. It never ceases to amaze me how with every new GCC release, software vendors a few months later will come out and say how their software is now faster as a result.

GCC 4.4 Release Series

Changes, New Features, and Fixes

http://gcc.gnu.org/gcc-4.4/changes.html

GCC 4.4.0 Release Candidate Is Now Out There

If you are into compilers and have not already tried out the latest bits from GCC 4.4, you may want to give the GCC 4.4.0 Release Candidate 1 a whirl. GCC 4.4.0 RC1 was tar'ed up yesterday and is now ready for testing.
GCC 4.4 has a number of benefits over GCC 4.3 in all areas. One of the GCC 4.4 features that excite us is the merging of the Graphite framework, which will ultimately provide automatic parallelization support. Also on the multi-threaded front, GCC 4.4 supports version 3.0 of OpenMP. While still experimental, in this GNU Compiler Collection update there is also better support for the C++0x language.

GCC To Receive Automatic Parallelization Support

IBM's Razya Ladelsky today outlined plans for providing automatic parallelization support within the GNU Compiler Collection. The Graphite Framework, which provides high-level loop optimizations based upon the polyhedral model, was merged for the forthcoming release of GCC 4.4 and it will be used eventually to provide some level of automatic parallelization support. Graphite will be combined with autopar, which is an automatic parallelization code generator based upon GOMP that in turn implements OpenMP.

Plug-in architecture on the way for the gcc

When Richard Stallman began writing Bison in 1983, he was only trying to build the bits of an operating system he would need to write another operating system. But that recursive goal was no stranger than the recursive name he would create for the software he would eventually create: the GNU Project, where GNU standard for “ GNU is Not Unix.”
And now, 25 years later, one of the most important tools to come out of the GNU Project’s drive for the GNU Operating System—the GNU Compiler Collection— has received approval from the Free Software Foundation to begin work on a plug-in architecture.
Mark Mitchell, founder of CodeSourcery, confirmed that the FSF gave its permission to prepare the gcc for plug-ins. This is the first time that such permission has been granted.

BSD Licensed PCC Compiler Imported

It is not yet bug-free, but it can compile the i386 userspace. The big benefit of it (apart from that it's BSD licensed, for license geeks :-) is that it is fast, 5-10 times faster than gcc, while still producing reasonable code.

Tools: GCC 4.2.0 Released

Mark Mitchell announced the availability of GCC 4.2 saying, "GCC 4.2.0 is a major release, containing new functionality not available in GCC 4.1.x or previous GCC releases." He then linked the GCC 4.2 Release Series Changes, New Features, and Fixes document for more details as to what is new in this release.
