v7, v8? Thats for ssh2? > Incidentally, if anyone wants to write some good, fast, well-tested > asm code for gmp on 68060 it'd be gratefully received.

I don't think many people still write asm, especially not for 68060... But I heard the gcc compiler produced pretty good code, if you just give it the right options. > I guess as a minimum the gmp configs ought to select the 68000 code in > preference to the 68020 when building for 060. I didn't follow this too closely, but I think the reasoning was you use -m68020-060 to build code that is "optimized" for all chips, ie uses no instructions that need to be emulated. The drawback is, that it slows down 020-040 quite a bit. That's why Richard suggested one deb optimized for 020-040, which runs pretty fast on all those chips, and one for 060, which should be way faster than the one-for-all version. But I'd prefer if somebody who knows about this, ie Richard, explains it again. AFAIK this has never been done on m68k yet. Christian
