    Phoronix: Intel Core 2, Core i7 Optimizations For GCC 4.6

    CodeSourcery, a company that works on GCC for various companies like with Texas Instruments for bringing the GNU Toolchain to new CPUs and also offers their own software development environment, has shared their intentions to provide a new set of GCC optimizations for Intel's Core 2 and Core i7 processors...

    Are they going to boycott AMD processors as Intel Compiler always did?

          Read the Phoronix article.

            Isn't the case with GCC that AMD themselves work on it, but Intel contracts it out?

              Looks like I may once again run Gentoo on my ThinkPad.

                Correction, seems Intel does have at least one person on GCC. Why this, then?

                  "They" is community. Patches for AMD won't be rejected unless it is just not good quality.

                  The thing with FLOSS is that 'what people do, happens. What they do not, does not happen'.

                  It just happens that nobody is in for making AMD optimizations, while there are people in for Intel optimizations.

                  Welcome to the world of customers take care for themselves. It is the opposite side of the "What gets the most users" as it is "What do I as a user want?".

                  Which is ultimately why Linux kicks so much ass

                    Well, if these optimization can be applied to AMD cpu's they will be. It's not like with Intel's own compiler where they can cripple the codepath for anything not genuine Intel. For Intel to use CodeSourcery seems smart since they have worked on GCC for a very long time and also has a member on the GCC steering commitee. My Core i7 looks forward to these optimizations

                      You probably don't have to worry:

                      I wonder if llvm also gets such optimizations? Thankfully there's only one way - BSD with clauses or not → GPL and no way back.

                        What sandbank has your head been hiding in? AMD has done of optimizations for GCC on their processor line. They aren't the only ones. PGI, Sun, Rapidmind, Pathscale, Absoft, Microsoft, etc. AMD has a long history of commiting patches to GCC as well as other projects such as open64 for processor optimizations with each family of processor release. Intel traditionally has done very little for optimizations with GCC.

                          Well they never "Boycotted" them, they did however cripple support for them. They can't do that however after the AMD/intel antitrust. It was part of the settlement.

                            If only intel farmed out their graphics development as well. You might see some decent performance then in linux from their graphics instead of the crippled performance they put out now.

                              Nope. They outsourced Poulsbo, both hardware and driver and it's a mess.
