It's 100% boilerplate. The whole "handicapping" debate that pops up every ICC thread is likely several years out of date (not that I don't expect to see it again and again for the next decade or two).
Case in point, take bench completion time on a Xeon supercomputer [1]. Compare that to relative completion time on an Opteron supercomputer [2] (for both, lower is better). If that's Intel's compiler handicapping AMD performance, I wonder what GCC is trying to do?
