[LLVMdev] Mips target instruction set

[William Morland]

Hi,

This is my first time posting on the list so as an introduction 
I'm a computer science student at the University of 
Cambridge. I'm currently involved in architecture research 
which involves the MIPS architecture hence an interest in the 
MIPS target on LLVM.

I was wondering whether there was any MIPS 64-bit 
development in progress that I should be aware of and if 
anyone else is currently actively working on the MIPS target 
in general? If no one else is working on it then I'm planning 
to add some 64-bit instruction support to the MIPS target for 
LLVM. It appears at the moment that the current instructions 
are 32-bit with some extra to the MIPS I specification? I'm 
planning to make my additions as discrete as possible 
through an include and such so as to avoid disrupting the 
current code although it looks as though it may be best to 
aim eventually for some kind of distinction through sub-
targets.

Thanks,
William Morland
