Unfortunately, the current state is objectively unknown, as MIPS 
is not part of the architectures that we do continuous 
integration testing on. I suggest trying to run the 
compiler/druntime/phobos tests on MIPS (either real hardware, or 
emulator) to see what works at this moment. It is likely that for 
bare metal enough of the language would be stable and working 
correctly, but we can't know for sure.

You can follow the instructions to cross-compile with LDC:
https://wiki.dlang.org/Building_LDC_runtime_libraries

And for GDC:
https://wiki.dlang.org/GDC_Cross_Compiler

If you need specific help any of those compilers, I suggest 
asking for help in their respective sections of the 
forum/newsgroup.
