LLVM's 64-bit ARM Back-End Is Almost Merged With Apple's Code

Back in March Apple open-sourced their 64-bit LLVM compiler back-end (ARM64) but by the time that was done there was already a 64-bit ARM back-end (AArch64) present within mainline LLVM that was created by other ARM stakeholders. For the past several weeks, all of the LLVM developers have been working on converting towards a single LLVM 64-bit ARM back-end. In the days ahead, that work should be complete.

Apple, LLVM Developers Figure Out Their 64-Bit ARM Approach

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.

Link-Time Optimizing Improved, But Still Takes A While On GCC 4.9

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.

Linux 3.15 Can Almost Be Compiled Under LLVM's Clang

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.

Running GCC 4.9 On AMD's AM1 Kabini With Jaguar Cores

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.
