LLVM Begins Gaining Ground On Windows

While the LLVM compiler infrastructure is supported to some extent on Microsoft Windows, the main focus of LLVM development has been -- and continues to be -- around Linux and OS X support. However, with a recent push, the LLVM toolchain is beginning to make more serious progress on Windows.

Chromebook Cortex-A15: GCC 4.8 vs. LLVM/Clang 3.3

It's been a while since last publicly releasing any GCC vs. LLVM/Clang compiler benchmarks from the Samsung Chromebook with Exynos 5 Dual Cortex-A15 SoC. However, uploaded to I have now released some new results.

GCC Core-AVX2 "Haswell" CPU Optimization Tests

Our latest tests from an Intel Core i7 4900MQ "Haswell" laptop are looking at the impact of applying CPU compiler optimizations for this high-end "core-avx2" processor when using a recent GCC 4.9 development snapshot.

GCC 4.9 Stacks Up ADA, Fortran Changes

GCC 4.9 isn't anticipated for release until H1'2014, but it's already been stacking up changes for several months. We have covered some of the new GCC 4.9 work already on Phoronix for this open-source compiler, but here's an overview of some of the other changes.

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?

Benchmarking The SLP Vectorizer On LLVM Clang 3.4

Following word this weekend that Apple and Google engineers agree on SLP vectorization by default for the LLVM/Clang compiler, I carried out some fresh SLP Vectorizer benchmarks this weekend from the LLVM Clang 3.4 SVN development code.

GCC 4.9, Clang 3.4 Will Have Better C++14 Support

We're still many months out from seeing the release of GCC 4.9 and LLVM Clang 3.4 releases, but with the next major updates to these open-source code compilers will come better support for the C++14 (C++1y) language.

Duetto Project Continues For Web-Based C++ Support

Duetto is an alternative open-source project to EmScripten, the LLVM-based project for compiling C/C++ code-bases into JavaScript for execution by modern HTML5 web-browsers. Duetto is still LLVM-based and relies on JavaScript, but there's a few changes over EmScripten.

New LLVM Clang Compiler Benchmarks: 3.2, 3.3, 3.4 SVN

From an older Intel Core i7 990X Extreme Edition "Gulftown" system the LLVM/Clang compiler performance of the 3.2 and 3.3 releases were compared to the current SVN code as of today. There are some LLVM 3.4 performance improvements while for other workloads there isn't much evolution to see.

LLDB 3.3 Grows In Use For Linux Developers

While the innovative LLVM compiler infrastructure is mentioned extremely often on Phoronix along with its Clang C/C++ compiler, receiving less coverage is LLDB. However, with LLVM 3.3, the LLVM Debugger has grown in functionality and is growing in usefulness.

Running GCC 4.9 With Intel's Core i7 "Core-AVX2"

I've already delivered GCC vs. LLVM Clang compiler benchmarks on Intel's Core i7 4770K "Haswell" platform and tested the "core-avx2" optimizations offered by the latest compilers. That previous testing was done from the stable releases of LLVM Clang 3.1/3.2 and GCC 4.7/4.8 releases, but looking ahead, here's some benchmarks of the latest GCC 4.9 development snapshot.
