GCC is getting quite better on MIPS in most recent revisions. I've seen numbers quoted around the "30%" range, though I'm not sure if that's with 64-bit longs and ptrs, what processor that's on, etc. I've not tried to do any measurements of it, but it does look a lot better in ways. Targetting an Origin 2000 is a ways off. First have to get everything else done (multi-user, not crashy, devices supported, etc.) Then doing the CPU and machine-specific stuff is a bit of work. Then doing SMP is a bit of work. I don't know of anyone with time+hardware+interest. By the time I have interest and it's feasible, I'll probably be short on time, let alone time to work with remore hardware. Hope this helps. Thanx, juli. -- juli mallett. jmallett@freebsd.org. adrift in the pacific.
