3. [PATCH] Add special MIPS multiply instructions

Same remark.
These are NEC VR54xx specific extensions to the MIPS instruction set.
They are used if you use GCC's -march=vr5400 option. See
www.necelam.com/docs/files/1375_V2.pdf
as well.
Can you add some kind of define or dynamic processor definnition in your
patch so that we can keep track of the exact instruction set ?
Yes, I will update the patch. Any ideas or proposals from
anybody how to do this the best way? Are there already
examples from other architectures?
I think a define to be able to completely select/unselect it
at compile time combined with possibility for dynamic
runtime selection would be the best?

Dirk
