"-mv8" compiles SparcLite code AKA SuperSPARC. As todays' machines are
usually using UltraSPARC processors, e.g. "uname -m" says "sun4u", using
anything better than the default (which is -mv7) should improve on
pipeline stalls, register handling, etc, and all the nifty actions a RISC
CPU expects from its compiler. You might want to look into the gcc info
page -> invocation -> submodel options -> SPARC options.

BTW, the gcc 2.8 series seems to compile things o.k. when using
-mcpu=ultrasparc, but the 2.95 series (used on an E450/Sol7/32&64 bit
mode) seems to break the code, when using -mcpu=ultrasparc. Anybody some
lead on this?

It should be available with the libkvm interface, but you might want to
have a look into "netstat -k" instead. Please don't ask me what all the
stuff in there is for...
