Detailed Description

A DefinitionGenerator that generates symbols by looking them up in the ORC runtime Session's instance symbols (via a Proxy).

Instance symbols are names that the ORC runtime gives to objects created at runtime, which have no symbols under the standard object models.

DefinitionGenerators should override this method to insert new definitions into the parent JITDylib.

K specifies the kind of this lookup. JD specifies the target JITDylib being searched, and JDLookupFlags specifies whether the search should match against hidden symbols. Finally, Symbols describes the set of unresolved symbols and their associated lookup flags.

Implements llvm::orc::DefinitionGenerator.
