Go up one level in this thread
I did manage to get the IPO and profile-guided optimizations to
work (the Users' guide is a bit sketchy here and doesn't mention
you have to use xilink). So the latest Intel results are (no
inline ASM, /Qprof_use /fast for optimization):
middlegame endgame
AMD 491 knps 818 knps
P4 559 knps 919 knps
A little below VC++ .NET for the middlegame but better than anything
else on the endgame test.
