[LLVMdev] Is it possible to run llvm on mips machine?

[James Molloy]

Hi,

There are numerous emails flying around the list at the moment regarding the state of the JIT. 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.

Have a look for the subject "[LLVMdev] MC-JIT Design".

Also, what sort of memory footprint would you require to use the JIT on a MIPS target? 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.
