Hi,

the last snapshot of GCC 4.0 compiles the NetBSD kernel correctly, if 
some warnings regarding signedness compatibility between some pointers 
are ignored and two errors fixed by changing an extern declaration into 
a static one.

I was wondering, now that I have available a kernel built with GCC 4.0 
(and the new option -combine) and one with GCC 3.3 how I could compare 
the throughput of the two kernels ?

Any ideas ?

Thanks !
Vincent
