GCC 4.8 Has Support For AMD Steamroller, Jaguar

Aside from improvements to Link-Time Optimizations, run-time library improvements, and a new optimization level, the coming release of GCC 4.8 also features support for yet-to-be-out AMD hardware. AMD's Steamroller "Bulldozer 3" processor is already supported with compiler optimizations and so is AMD Jaguar, their new low-power APU that's rumoured to be in the next-generation consoles.

64-bit ARM (AArch64) Support Merged Into LLVM

GCC has had support for 64-bit ARM, a.k.a. AArch64, going back to last summer for using the open-source compiler with next-generation ARMv8 hardware. Being merged today is finally support for the LLVM compiler infrastructure with an experimental 64-bit ARM/AArch64 back-end target.

C++11 & The Long-Term Viability Of GCC Is Questioned

Back on Tuesday there was a basic email by a developer volleyed on the GCC mailing list, which has since sparked dozens of responses and a rather interesting conversation about the future of the GNU Compiler Collection and its ultimate path and viability moving forward. The initial e-mail was simply an inquiry asking about an estimated time-frame for having full support of the ISO C++11 specification. Diego Novillo, a well known GCC developer and Google employee, has even expressed fear that GCC may be past the tipping point and could die out naturally.

GCC 4.8 Improves Its Runtime Library (libstdc++)

There's been many Phoronix articles already covering features and changes coming to GCC 4.8, the next major compiler update to come out of the Free Software Foundation in March or April. One of the areas that's seen improvements in GCC 4.8 and not talked about much yet is the improvements to its runtime library, libstdc++, with new features being present.

Emscripten-Qt: Bringing Qt, C++ To The Web

Since late 2011 there has been Emscripten, the interesting project that allows generating JavaScript out of LLVM Bitcode. Emscripten thus allows for C/C++ code -- and in effect anything else that can be lowered down into LLVM Bitcode -- to be turned into JavaScript and run from a modern web-browser. Another project that has since come about is Emscripten-Qt, which is a port of the Qt tool-kit to JavaScript and HTML5 for use by web-browsers.

LLVM Developers Ponder Using C++11 Features

While C++11 is an ISO standard and the Clang C/C++ compiler front-end to LLVM has been supporting C++11, developers behind the LLVM compiler infrastructure are still deciding whether to allow C++11 language features within their code-base.

You Can Now Run LLVM Assembly In Your Web-Browser

Thanks to some experimental and innovative work done on LLVM, it's now possible to parse and execute LLVM Assembly within your web-browser. This Assembly code from the LLVM compiler infrastructure is then translated to JavaScript using EmScripten.
