GetForTargetProcess()

inlinestatic

Creates a ExecutorResolutionGenerator that searches for symbols in the target process.

Load()

Expected< std::unique_ptr< ExecutorResolutionGenerator > > llvm::orc::ExecutorResolutionGenerator::Load ( ExecutionSession & ES, const char * LibraryPath, SymbolPredicate Allow = SymbolPredicate(), AbsoluteSymbolsFn AbsoluteSymbols = absoluteSymbols )

static

Permanently loads the library at the given path and, on success, returns an ExecutorResolutionGenerator that will search it for symbol definitions in the library.

On failure returns the reason the library failed to load.

tryToGenerate()

Error llvm::orc::ExecutorResolutionGenerator::tryToGenerate ( LookupState & LS, LookupKind K, JITDylib & JD, JITDylibLookupFlags JDLookupFlags, const SymbolLookupSet & LookupSet )

overridevirtual

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.
