Somebody in this dev-list alreday did it with LLVM.

I guess you are speaking about Bruno Cardoso Lopes ? I can see there is a MIPS implementation in LLVM repository but it looks like uncomplete (that is, I'm not even sure it can compile any source). What I hope is to have a complete MIPS implementation so I can adapt it for PlayStationPortable and add the necessary stuff so that it may use VFPU registers and instructions (processor specialised into vector and matrix operations).

to "consult" me ? I'm not sure to understand what you mean.
