Using AddressSanitizer & ThreadSanitizer In GCC 4.8

While born originally at Google as projects for LLVM, AddressSanitizer and ThreadSanitizer have been ported to GCC and will be part of the forthcoming GCC 4.8 compiler release. Back at Google, they're onto developing MemorySanitizer for LLVM.

A Basic Look At How The LLVM Compiler Works

The LLVM compiler infrastructure is frequently talked about on Phoronix whether it be about its Clang C/C++ compiler or one of the innovative use-cases for LLVM such as with the LLVMpipe Gallium3D driver or as a JIT engine within some free software projects like Mono. However, for those that don't understand much of the internals of LLVM, here's a brief overview.

The State Of 64-Bit ARM (AArch64) On LLVM/Clang

ARM's AArch64 back-end for LLVM to handle the 64-bit ARMv8 architecture is working, but there's still more work ahead of the hardware's general availability in about one year's time.

Pairing A C Compiler With QEMU's Code Generator

Earlier this week when writing about the state of the Tiny C Compiler, I learned more about QCC. QCC is a new initiative to pair a forked version of the Tiny C Compiler (TCC) with QEMU's code generator.

Clang Can Analyze Code Comments, Generate Docs

Aside from why LLVM/Clang was ported to one of the fastest super computer's in the world and using Clang to implement Microsoft's C++ AMP, another interesting session at this month's LLVM Developers' Conference in San Jose was about using Clang to analyze code comments.

Why LLVM/Clang Was Ported To A Super Computer

Most often whenever writing about LLVM and its Clang C/C++ compiler front-end on Phoronix, within the forums is a flurry of comments from those in support of and against this modular compiler infrastructure. Some are against LLVM/Clang simply because its BSD-licensed and sponsored by Apple rather than the GPLv3-licensed GCC backed by the FSF. Others, meanwhile, see LLVM as presenting unique advantages and benefits. What reasons would a leading US national laboratory have for deploying LLVM/Clang to their leading super-computer? Here's an explanation from them.

Intel Makes Microsoft's C++ AMP Cross-Platform

Microsoft conceived C++ Accelerated Massive Parallelism (AMP) as a library atop DirectX 11 for offering data-parallelism directly in C++ that can make easy use of GPUs while having CPU fall-back support. With C++ AMP being similar to OpenCL, Intel engineers decided to implement the Microsoft specification within OpenCL and using LLVM/Clang so that it can be used cross-platform.
