C Language Modules For LLVM Still Being Tackled

Last year at the LLVM developers' meeting it was proposed by an Apple engineer the concept of "modules" for C code in LLVM/Clang to replace the common development approach for C/C++ languages of including header files and passing the library to the linker. LLVM modules seek to take a different approach.

Compilation Times, Binary Sizes For GCC 4.2 To GCC 4.8

Compiler benchmarks at Phoronix commonly look at the performance of resulting binaries while less of a focus is the compilation time and binary sizes. However, a developer has carried out GCC benchmarks of the compilation times and binary sizes in different scenarios for GCC releases going from GCC 4.2 to the upcoming GCC 4.8.

Tilera Publishes TILE-Gx CPU Back-End To LLVM

After already having integrated TILE-Gx support into GCC 4.7, Tilera is now calling for the mainlining of its TILE-Gx back-end into LLVM. The LLVM Tile-Gx back-end is needed for the company's forthcoming many-core processor.

GCC 4.8 To Bump Up Speed On NVIDIA's Tegra 3

How's the NVIDIA Tegra 3 performance with its four Cortex-A9 cores performing under the forthcoming GCC 4.8 release? Here's some new benchmarks, similar to the recent compiler testing with the ARM Cortex-A15.

GCC Prepares Compiler Support For Intel Broadwell

While Intel Haswell processors won't even be released to the public until later this year, compiler developers have already been working on supporting the new instruction set extensions of Haswell for more than one year. GCC developers already have early Intel Broadwell support ready for GCC 4.8.

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.

CLDOC: A Clang-Based C/C++ Document Generator

CLDOC is a document generator for C and C++ projects to create documentation automatically out of comments as well as creating XML-based descriptions of the API. CLDOC is a new project but already sounds promising and is being powered by LLVM's Clang C/C++ front-end for its parser.

Link-Time Optimizations With GCC 4.8

GCC 4.8 will feature a few improvements when it comes to LTO, a.k.a. Link-Time Optimization, but will this reflect in any greater performance for the resulting binaries?

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.

Unpleasant: LLVM/Clang 3.2 On The ARM Cortex-A15

Since publishing LLVM/Clang 3.2 benchmarks a few days ago that showed the Clang C/C++ compiler competing with -- and in some cases outperforming -- the GCC compiler on Intel x86_64, several Phoronix readers have been asking how things compare on the ARM side.
