GCC Explorer - an interactive take on compilation

Matt Godbolt announces GCC explorer, a web-based tool for exploring how code tweaks change the machine code emitted by the compiler. "Particularly with some of the newer features of C++11 — lambdas, move constructors, threading primitives etc — it’s nice to be able to see how your elegant code becomes beautiful (and maybe even fairly optimal) machine code." The GCC explorer code is on github for those who want to set up their own instance.
