Niels,
We need a forum for both posting patches, and discussing the same
patches. To me, it seems easiest to have both on the same list.
however maybe not all people on gmp-devel are interested by the
detail of all patches and
I think all you T3/T4 changes are now in. Please check that I didn't
mess something up.
Thanks for this contribution!

The addmul code could be simularly improved.
Grumble... and I did this work already, I sent older versions
of my T3/T4 changes, let me go see how I screwed this

I optimised submul_1.asm, and then edited both addmul_1 and submul_1 to
use as similar operand order as possible. Please test these using
tests/devel/try, and please time this new submul_1.

Why doesn't your functions use the 'return' insns, btw?
