llvm dev - Apr 2017 - Using a function from lib/Target/(any arch)/ in lib/ExecutionEngine/RuntimeDyld/

Hello LLVMDevs,

I have written a .cpp file in lib/Target/(some arch)/ and i want to use one
of its function in a file in lib/ExecutionEngine/RuntimeDyld/. So is there
any specific way to do that. This may be a general question for any one who
writes a .cpp file in Target/(any arch)/ and tries to use it somewhere in
ExecitionEngine/RuntimeDyld/. Please guide.

Thanks,
Siddharth

Maybe you can see how other targets under ExecitionEngine/RuntimeDyld/Targets
do?

Hi Siddharth,

As far as I know this is not currently possible. Current RuntimeDyld
implementations are all self-contained and do not reference code from their
targets.

Having RuntimeDyld depend on code from a custom target seems reasonable
though. It might be better in the long term if we moved all the
target-specific code out of ExecutionEngine and just provided registration
functions so that targets could register their respective RuntimeDyld
implementations with ExecutionEngine. This would be a significant refactor
though, and we'd want to sanity-check its impact on LLVM's library
layering.

Cheers,
Lang.
