A few hours ago I wrote about the most interesting features for the Linux 3.15 kernel from my perspective as it didn't look like anything else interesting would be introduced this late in the merge window before the imminent 3.15-rc1. However, this time I've been happily proven wrong with Clang patches being added to the Linux 3.15 kernel.
The annual European LLVM Conference happened this past week in Edinburgh, Scotland. Slides and other media from the LLVM compiler infrastructure presentation are now available.
Using the AMD Athlon 5350 AM1 APU with its four "Jaguar" cores operating at 2.05GHz, I ran some benchmarks from Ubuntu 14.04 Linux comparing the performance of binaries compiled under GCC 4.8.2 and this week's GCC 4.9.0 RC1. Is GCC 4.9 better able to exploit the potential out of AMD's Jaguar microarchitecture? Let's see.
Point releases to the LLVM compiler infrastructure are finally becoming a reality with the LLVM 3.4.1 release being just days away.
As the annual update to the GNU Compiler Collection, GCC 4.9 is poised to be released in the days ahead. The first release candidate was issued today and it's a very hefty update to this leading open-source compiler.
ARM Compiler 6 is beginning to use the LLVM/Clang compiler.
The Dropbox cloud storage provider has announced Pyston, their own open-source JIT compiler to Python. The big focus with Pyston is on speed.
Version 0.10 of Rust is not out from the Mozilla community and it's a huge update.
For years I've heard of LLVM planning to spin off into its own non-profit, independent organization and today that's finally moving forward.
With GCC 4.9 likely being released in the next few weeks, here are some benchmarks comparing the GCC 4.8.2 stable release against the latest GCC 4.9 snapshot.
Back in September of last year after Apple unveiled the iPhone 5S smart-phone with a 64-bit processor, they said they would ultimately open-source their 64-bit ARM compiler back-end... A half-year later, we're finally seeing this code that yields another AArch64 back-end for LLVM.
There's long been talk of doing LLVM point releases with an increasing number of external projects relying upon the open-source compiler infrastructure, but it looks like next month may be the first time for this to happen with LLVM 3.4.1.
The ISO C++ committee has reached the point of possibly having the final draft of C++14 as a minor update to the widely-used programming language. For those curious about the likely changes to find with C++14, here's an article to checkout.
While GCC 4.9 is running behind schedule compared to where GCC 4.8 was at this time last year, open-source developers banding together still might get out the GNU Compiler Collection 4.9 release in early April with its many new compiler features.
Support for the OpenACC parallel programming standard for heterogeneous CPU/GPU systems has been added to GCC's Fortran compiler front-end.
Version 2.1 of the LLVM-based Capstone Disassembly Framework is now available.
Besides GCC looking towards new features and improvements this year via Google's Summer of Code, the LLVM project also has a growing list of hopeful projects for student developers.
Ending out February, compiler developer Chandler Carruth at Google flipped the upstream LLVM build systems to building under C++11 by default. So far nothing has broken and in the days ahead they will carry out more tests in their approach to now using C++11 features by default as they develop this leading compiler infrastructure.
For any students looking to get involved with this year's Google Summer of Code, the GNU Compiler Collection (GCC) has several interesting projects that are looking to be tackled.
LLVM's Clang compiler now has a virtual file-system implementation.
The forthcoming release of the GCC 4.9 compiler will feature support for Advanced Vector Extensions 512 (AVX-512) although this instruction set extension won't be appearing on Intel CPUs for a while.
As an interesting turn of events after Richard Stallman called LLVM a "terrible setback" and the discussion that ensued, it turns out that the GCC and LLVM/Clang developers might start to better collaborate under some sort of open-source compiler initiative.
A group of developers remain hard at work on the LLVMLinux project to build the mainline Linux kernel on x86 and ARM with the Clang compiler.
For those users with SPARC64 hardware, LLVM's Clang compiler has received support for this CPU architecture.
Phoronix was the first to report widespread on Richard Stallman calling LLVM a "terrible setback" with the innovative and growing compiler infrastructure being put out under a BSD-style license instead of the GPL. Well, a little known fact is that when LLVM was first starting out, Apple tried integrating LLVM changes with GCC but it was rejected by the GCC developers.
Samsung is still working towards bringing OpenACC support to GCC. We've seen Samsung developers working on OpenACC for GCC over the past several months -- along with other OpenACC initiatives out of CodeSourcery, etc -- and now there's some new OpenACC GCC Fortran patches.
In the days since Eric S. Raymond had some choice words about GCC vs. Clang, the bickering and fighting over GCC vs. Clang compilers has continued. Richard M. Stallman has come out this morning on the Free Software Foundation's mailing list with his views to reiterate.
Eric S. Raymond has made some very interesting -- and what surely will be considered very controversial remarks -- about the Free Software Foundation's views on the GCC compiler and its lack of acceptance towards (potentially non-free) compiler plug-ins in a time of LLVM's Clang existence and ongoing acceptance.
