...er there is no support for vector instructions. I see that vectorization is a very powerfull weapon from LLVM when compared to other compilers but in the case of the Allegrex CPU it is not supported. Are there any plans in the near future to add support for it? If not, which CPUs have some kind of VFPU support already implemented so someone totally noob into the LLVM tablegen could try to look to add it?

...? 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). > He seems to consult you. to "consult" me ? I'm not sure to understand what you mean. Regards

...s not complete yet but i'm working on it. I can compile simple sources.

That's cool, i have plans to do the same for ps2 :) > He seems to consult you. > > to "consult" me ? I'm not sure to understand what you mean. > > Regards > ______...
