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

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


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 ?
