Abstract
With the advent of machines with large address spaces, and inexpensive very fast networking, it is possible to defer most of the optimization to a point where most, if not all of the program is available for analysis. As the name suggests, Link Time Optimization (LTO) does most of the work at link time. With that addition of profile directed feedback, it is possible to perform many optimizations that are simply not feasible for conventual compilation or just in time compilation. This talk will discuss the addition of LTO into the Gnu Compiler Collection.
