GCC Link-Time-Optimization and the Linux Kernel - Andi Kleen, Intel

Sign up or log in to save this to your schedule and see who's attending!

One of the major new features in gcc 4.7 was Link Time Optimization. This allows aggressive optimizations over whole programs. This talkis about applying LTO to a large and sophisticated existing project: the Linux kernel. It required numerous changes both to gcc and the kernel and also to binutils. This talk discusses some experiences gained from the project, the state of the LTO kernel, and some open problems in the gcc LTO implementation.
