Besides shorter compile times and other benefits, one of the other commonly talked about advantages of using LLVM's Clang C/C++ compiler is its arguably excellent static analyzer tool.
Google has released a port of their GCC AutoFDO utility for LLVM for directing optimizations back into the compiler from the Linux kernel perf support.
Two weeks ago Apple open-sourced their 64-bit ARM back-end to LLVM. Following last week's EuroLLVM meeting, they have decided that the community's existing open-source 64-bit ARM back-end will likely be merged into Apple's now-public back-end.
The GCC 4.9 compiler that's about to be released has many improvements, including in the area of LTO (Link-Time Optimizations), but you must still have a fair amount of patience to compile with LTO support.
Fracture is another open-source project aiming to offer users/developers the ability to decompile binaries back into an intermediate form.
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.
