Blocking version of lookup above.

Returns the resolved symbol map. If WaitUntilReady is true (the default), will not return until all requested symbols are ready (or an error occurs). If WaitUntilReady is false, will return as soon as all requested symbols are resolved, or an error occurs. If WaitUntilReady is false and an error occurs after resolution, the function will return a success value, but the error will be reported via reportErrors.

Expected< ExecutorSymbolDef > llvm::orc::ExecutionSession::lookup	(	const JITDylibSearchOrder &	SearchOrder,

◆ lookup() [5/5]

		const JITDylibSearchOrder &	SearchOrder,
		SymbolLookupSet	Symbols,
		SymbolState	RequiredState,
		SymbolsResolvedCallback	NotifyComplete,
		RegisterDependenciesFunction	RegisterDependencies
	)

Search the given JITDylibs for the given symbols.

SearchOrder lists the JITDylibs to search. For each dylib, the associated boolean indicates whether the search should match against non-exported (hidden visibility) symbols in that dylib (true means match against non-exported symbols, false means do not match).

The NotifyComplete callback will be called once all requested symbols reach the required state.

If all symbols are found, the RegisterDependencies function will be called while the session lock is held. This gives clients a chance to register dependencies for on the queried symbols for any symbols they are materializing (if a MaterializationResponsibility instance is present, this can be implemented by calling MaterializationResponsibility::addDependencies). If there are no dependenant symbols for this query (e.g. it is being made by a top level client to get an address to call) then the value NoDependenciesToRegister can be used.

The handler becomes callable from the executor using the ORC runtime __orc_rt_jit_dispatch function and the given tag.

Tag symbols will be looked up in JD using LookupKind::Static, JITDylibLookupFlags::MatchAllSymbols (hidden tags will be found), and LookupFlags::WeaklyReferencedSymbol. Missing tag definitions will not cause an error, the handler will simply be dropped.

Closes the given JITDylib.

This method clears all resources held for the JITDylib, puts it in the closed state, and clears all references held by the ExecutionSession and other JITDylibs. No further code can be added to the JITDylib, and the object will be freed once any remaining JITDylibSPs to it are destroyed.
