How to add c++ function to LLJIT?

[lanistor]

There is no addGlobalMapping in LLJIT, i found InProcessMemoryManager, but there is no demo to explain it, and also lack of docs.

Hi vifird. You should use LLJIT::defineAbsolute instead.

@lhames Thanks a lot.

@lhames And how to use it? how to get JITEvaluatedSymbol of c++ function? I cannot find any example in source code or stackoverflow.

[lhames]

defineAbsolute is just a wrapper for the absoluteSymbols function, which is documented in https://llvm.org/docs/ORCv2.html
