[LLVMdev] Questions on using LLVM to build a VM

[Haohui Mai]

Tyler,

I think you might be looking for a JIT in ARM architecture. It seems  
that it has been "out of box" in LLVM distribution already, probably  
you might need some work to fit them into your system.

I suggest you have a look at the Kaleidoscope example. It uses a trick  
to make standard functions, like abs / cot available to Kaleidoscope.  
You might implement your system in similar way.
