State of MIPS

[April via Digitalmars-d-learn]

What's the current state of MIPS compiling for bare metal? 
Especially the R4300i processor. I see MIPS on both GDC and LDC 
"partial support/bare metal" lists but them being somewhat vague 
about it I'm not quite sure which it means and I'm sure by now 
the processors and instruction sets are different from what they 
were in 1995.

Thanks,
April.
