The most recent source code for Clang -- the default compiler in Xcode -- now shows support for a quad-core Marvell processor, the ARM-based Armada XP, according to Ars Technica. The chip is notably built for low-powered cloud computing tasks. Support can only be enabled when an "open source" flag is left undefined, something believed to imply that only Apple's own Clang binaries can compile for the XP.
