GCC hacks in the Linux kernel (developerWorks)

IBM developerWorks looks at several special capabilities of the GNU Compiler Collection (GCC) suite built into the Linux kernel. "GCC and Linux are a great pair. Although they are independent pieces of software, Linux is totally dependent on GCC to enable it on new architectures. Linux further exploits features in GCC, called extensions, for greater functionality and optimization. This article explores many of these important extensions and shows you how they're used within the Linux kernel."
