[LLVMdev] Using lazyFunctionCreator with external libraries in MCJIT

[Kaylor, Andrew]

Hi Jonatan,

When MCJIT encounters an unresolved symbol it calls a function in the memory manager (getSymbolAddress) to see if the memory manager can resolve the symbol.  It should be possible for a custom memory manager to use this call to generate a function.

I don't think that MCJIT supports the lazyFunctionCreator in the way the old JIT engine did.

I had posted a related problem earlier, howver I have made great progress since then and can re-address this as a much simpler question:

Is it possible to resolve external funtion symbols in dynamic libraries using a lazyFunctionCreator while running in MCJIT?

And if not, is it possible to in any other way get a dynamic library to call back into MCJIT to generate functions during runtimes?

For context, my previous thread is: Selectively Jitting using MCJIT
