Member Typedef Documentation

◆ GlobalValueSet

using llvm::orc::IRPartitionLayer::GlobalValueSet = std::set<const GlobalValue *>

Definition at line 41 of file IRPartitionLayer.h.

◆ PartitionFunction

using llvm::orc::IRPartitionLayer::PartitionFunction = std::function<std::optional<GlobalValueSet>(GlobalValueSet Requested)>

Partitioning function.

Definition at line 44 of file IRPartitionLayer.h.

Constructor & Destructor Documentation

◆ IRPartitionLayer()

IRPartitionLayer::IRPartitionLayer	(	ExecutionSession &	ES,
		IRLayer &	BaseLayer
	)

Construct a IRPartitionLayer.

Definition at line 102 of file IRPartitionLayer.cpp.

Member Function Documentation

◆ compileRequested()

std::optional< IRPartitionLayer::GlobalValueSet > IRPartitionLayer::compileRequested ( GlobalValueSet Requested )

static

Off-the-shelf partitioning which compiles all requested symbols (usually a single function at a time).

Definition at line 110 of file IRPartitionLayer.cpp.

◆ compileWholeModule()

std::optional< IRPartitionLayer::GlobalValueSet > IRPartitionLayer::compileWholeModule ( GlobalValueSet Requested )

static

Off-the-shelf partitioning which compiles whole modules whenever any symbol in them is requested.

Definition at line 115 of file IRPartitionLayer.cpp.

◆ emit()

void IRPartitionLayer::emit	(	std::unique_ptr< MaterializationResponsibility >	R,
		ThreadSafeModule	TSM
	)

overridevirtual

Emits the given module.

This should not be called by clients: it will be called by the JIT when a definition added via the add method is requested.

Implements llvm::orc::IRLayer.

Definition at line 119 of file IRPartitionLayer.cpp.

References assert(), llvm::orc::IRLayer::getExecutionSession(), llvm::orc::IRLayer::getManglingOptions(), and llvm::orc::ThreadSafeModule::withModuleDo().

◆ setPartitionFunction()

void IRPartitionLayer::setPartitionFunction ( PartitionFunction Partition )

Sets the partition function.
