Apple Open-Sources Its Unwinder For LLVM

Earlier this week there was the news of Intel contributing their OpenMP Runtime to LLVM in order to advance the open-source compiler project. Now to end off the week is news that Apple, who continues to invest significantly into LLVM and employs many of the key contributors, has open-sourced their stack unwinder for the project.

OpenMP 4.0 Support Is Ready For The GCC Compiler

Today in open-source multi-threading compiler news there's been word of Intel having their OpenMP Run-Time Library be a new LLVM sub-project and Cilk-Plus multi-threading support being cleared for GCC. In an abnormally interesting day for open-source compiler news, OpenMP 4.0 support is now ready for mainlining in GCC.

Intel Cilk Plus Multi-Threading Support Going Into GCC

This morning there was news of Intel committed their open-source OpenMP Run-Time Library as a new LLVM project. Now this afternoon there's more good news for multi-threading in open-source compilers: the GCC steering committee will allow Intel to add their Cilk+ Runtime Library to the GCC code-base as they add multi-threading Cilk Plus C/C++ support to the compiler.

Intel Ships Open-Source OpenMP Runtime For LLVM

While LLVM's Clang C/C++ compiler has made amazing progress in recent times, one of the features it's sorely been missing has been OpenMP support to allow it to better compete with GCC in many multi-threaded workloads. There's been numerous projects to work on OpenMP support in LLVM/Clang and most recently Intel has been taking up the work. Intel's latest announcement in the area is that they have decided to open-source their own OpenMP Runtime as a new LLVM sub-project.

Duetto Clang C++ For The HTML5 Web Is Now In Beta

Several months ago I wrote about the Duetto C++ compiler that is based upon LLVM's Clang and looks to take C++ programming to the HTML5 web. We hadn't heard anything out of the project since then, but today they're announcing their first public beta.

Cling: An Interactive, JIT-Based C++ Interpreter

After writing about ClangFormat yesterday as an interesting LLVM project that leverages Clang to automatically reformat C/C++ source-code, a Phoronix reader wrote in about another interesting project, Cling. Cling is an interactive C++ interpreter that uses Clang for Just-In-Time compilation.

Intel Core i7 4900MQ Haswell Running LLVM Clang 3.4

The latest benchmark results to share from the System76 Gazelle Pro, a Linux laptop with an Intel Core i7 4900MQ "Haswell" processor, are some current benchmarks of the LLVM Clang 3.4 SVN compiler development code. Is there much churn over the latest LLVM/Clang 3.3 stable on this latest-generation Intel CPU?
