John Polstra is really our most active ELF/Compiler person, and so he would likely be a better "official FreeBSD" interface. He is also less politically likely to insert his foot into his eating orifice. I do have some PPro mods, and they appear to help performance on average. The PPro is a really wierd creature (like the K6.) The darned processor does so much optimization, it appears to be insensitive to code mods. There are areas of reasonable payoffs, and lots of "obvious" optimizations that end up being neutral. -- John | Never try to teach a pig to sing, dyson@freebsd.org | it just makes you look stupid, jdyson@nc.com | and it irritates the pig.
