llvm dev - May 2019 - ORC - which example code?

Trying to put together a simple test JIT compiler, using ORC which as I
understand it will be the supported API going forward, I noticed that in
the first chapter of the updated Kaleidoscope tutorial, there is sample
code that starts like this:

ExecutionSession ES;
RTDyldObjectLinkingLayer ObjectLayer;
IRCompileLayer CompileLayer;

DataLayout DL;
MangleAndInterner Mangle;
ThreadSafeContext Ctx;

But in https://llvm.org/devmtg/2016-11/Slides/Hames-ORC.pdf there is sample
code that looks like this:

ObjectLinkingLayer LinkLayer;
SimpleCompiler Compiler(TargetMachine());
IRCompileLayer<…> CompileLayer(LinkLayer, Compiler);

Related but significantly different.

Which version is now considered correct/preferred?

Hi Russell
As far as I know, the second is preferred. You can also look at the LLJIT
&& LLLazyJIT stack in the trunk which is off the shelf utility.
Thanks

It turns out that ObjectLinkingLayer doesn't exist; that identifier occurs
in the source tree only in comments, never as an identifier.

Does that mean the second version of the API has been deleted and the first
is now correct?
