In its current state it is infeasible to add support for another architecture (very difficult to say the least) - there are plans currently being formulated to deal with this and convert the JIT to the new MC architecture, which would allow much easier porting between platforms.

Yes, I read it and still need some time to understand it.

The JIT currently (and the next incarnation is also likely to) pulls in an awful lot of fat LLVM libraries that cause a JIT-based compiler to be 8MB-up on x86. MIPS would be substantially larger than this due to its RISC instruction set.
I will use it on a MIPS PC Which have typically more than one Gigebyte
memory. Anyway, I think I should spend some time to understand MC-JIT
