Create an AbsoluteSymbolsMaterializationUnit with the given symbols.

JITEvaluatedSymbol FooSym = ...;
if (auto Err = JD.define(absoluteSymbols({{Foo, FooSym}})))

◆ cloneFunctionDecl()

Function * llvm::orc::cloneFunctionDecl	(	Module &	Dst,
		const Function &	F,
		ValueToValueMapTy *	VMap = `nullptr`
	)

Clone a function declaration into a new module.

This function can be used as the first step towards creating a callback stub (see makeStub), or moving a function body (see moveFunctionBody).

If the VMap argument is non-null, a mapping will be added between F and the new declaration, and between each of F's arguments and the new declaration's arguments. This map can then be passed in to moveFunction to move the function body if required. Note: When moving functions between modules with these utilities, all decls should be cloned (and added to a single VMap) before any bodies are moved. This will ensure that references between functions all refer to the versions in the new module.

◆ getObjectSymbolFlags()

Expected< SymbolFlagsMap > llvm::orc::getObjectSymbolFlags	(	ExecutionSession &	ES,
		MemoryBufferRef	ObjBuffer
	)

Returns a SymbolFlagsMap for the object file represented by the given buffer, or an error if the buffer does not contain a valid object file.

◆ getResponsibilitySetWithLegacyFn()

template<typename FindSymbolFn >

Expected<SymbolNameSet> llvm::orc::getResponsibilitySetWithLegacyFn	(	const SymbolNameSet &	Symbols,
		FindSymbolFn	FindSymbol
	)

Use the given legacy-style FindSymbol function (i.e.

a function that takes a const std::string& or StringRef and returns a JITSymbol) to get the subset of symbols that the caller is responsible for materializing. If any JITSymbol returned by FindSymbol is in an error state the function returns immediately with that error.

Useful for implementing getResponsibilitySet bodies that query legacy resolvers.

		JITDylib &	SourceJD,
		SymbolAliasMap	CallableAliases,
		VModuleKey	K = `VModuleKey()`
	)

inline

Define lazy-reexports based on the given SymbolAliasMap.

Each lazy re-export is a callable symbol that will look up and dispatch to the given aliasee on first call. All subsequent calls will go directly to the aliasee.

◆ lookupWithLegacyFn()

template<typename FindSymbolFn >

SymbolNameSet llvm::orc::lookupWithLegacyFn	(	ExecutionSession &	ES,
		AsynchronousSymbolQuery &	Query,
		const SymbolNameSet &	Symbols,
		FindSymbolFn	FindSymbol
	)

Use the given legacy-style FindSymbol function (i.e.

a function that takes a const std::string& or StringRef and returns a JITSymbol) to find the address and flags for each symbol in Symbols and store the result in Query. If any JITSymbol returned by FindSymbol is in an error then Query.notifyFailed(...) is called with that error and the function returns immediately. On success, returns the set of symbols not found.

Useful for implementing lookup bodies that query legacy resolvers.

◆ makeStub()

void llvm::orc::makeStub	(	Function &	F,

	)

Turn a function declaration into a stub function that makes an indirect call using the given function pointer.

void llvm::orc::moveFunctionBody	(	Function &	OrigF,
		ValueToValueMapTy &	VMap,
		ValueMaterializer *	Materializer = `nullptr`,
		Function *	NewF = `nullptr`
	)

Move the body of function 'F' to a cloned function declaration in a different module (See related cloneFunctionDecl).

If the target function declaration is not supplied via the NewF parameter then it will be looked up via the VMap.

This will delete the body of function 'F' from its original parent module, but leave its declaration.

void llvm::orc::moveGlobalVariableInitializer	(	GlobalVariable &	OrigGV,

	)

Move global variable GV from its parent module to cloned global declaration in a different module.

If the target global declaration is not supplied via the NewGV parameter then it will be looked up via the VMap.

This will delete the initializer of GV from its original parent module, but leave its declaration.

inline

Create a materialization unit for re-exporting symbols from another JITDylib with alternative names/flags.

If MatchNonExported is true then non-exported symbols from SourceJD can be re-exported. If it is false, attempts to re-export a non-exported symbol will result in a "symbol not found" error.

SymbolStringPtr Baz = ...;
SymbolStringPtr Qux = ...;
if (auto Err = JD.define(symbolAliases({
    {Baz, { Foo, JITSymbolFlags::Exported }},
    {Qux, { Bar, JITSymbolFlags::Weak }}}))
  return Err;
