2. [PATCH][MIPS] add "lwu" instruction

On which MIPS CPU is it defined ? Need to track instruction sets
exactly to be able to select a given MIPS CPU at compile time or
dynamically.
3. [PATCH] Add special MIPS multiply instructions
http://lists.gnu.org/archive/html/qemu-devel/2006-04/msg00375.html
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 ?
Fabrice.
