Member Function Documentation

◆ compileRequested()

Optional< CompileOnDemandLayer::GlobalValueSet > llvm::orc::CompileOnDemandLayer::compileRequested ( GlobalValueSet  Requested)
static

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

Definition at line 102 of file CompileOnDemandLayer.cpp.

◆ compileWholeModule()

Optional< CompileOnDemandLayer::GlobalValueSet > llvm::orc::CompileOnDemandLayer::compileWholeModule ( GlobalValueSet  Requested)
static

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

Definition at line 107 of file CompileOnDemandLayer.cpp.

References llvm::None.

◆ emit()

void llvm::orc::CompileOnDemandLayer::emit ( 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.

◆ setPartitionFunction()

void llvm::orc::CompileOnDemandLayer::setPartitionFunction ( PartitionFunction  Partition)

Sets the partition function.
