Member Function Documentation

add()

Error llvm::orc::IRLayer::add ( JITDylib &  JD, ThreadSafeModule  TSM, VModuleKey  K = VModuleKey()  )

virtual

Adds a MaterializationUnit representing the given IR to the given JITDylib.

Definition at line 22 of file Layer.cpp.

Referenced by getCloneToNewContextOnEmit(), and llvm::orc::ObjectLayer::getExecutionSession().

emit()

virtual void llvm::orc::IRLayer::emit ( MaterializationResponsibility  R, ThreadSafeModule  TSM  )

pure virtual

Emit should materialize the given IR.

Implemented in llvm::orc::CompileOnDemandLayer, llvm::orc::IRCompileLayer, and llvm::orc::IRTransformLayer.

getCloneToNewContextOnEmit()

bool llvm::orc::IRLayer::getCloneToNewContextOnEmit ( ) const

inline

Returns the current value of the CloneToNewContextOnEmit flag.

Definition at line 48 of file Layer.h.

getExecutionSession()

ExecutionSession& llvm::orc::IRLayer::getExecutionSession ( )

inline

Returns the ExecutionSession for this layer.

Definition at line 32 of file Layer.h.

Referenced by llvm::orc::IRTransformLayer::emit(), llvm::orc::IRCompileLayer::emit(), and llvm::orc::CompileOnDemandLayer::emit().

setCloneToNewContextOnEmit()

void llvm::orc::IRLayer::setCloneToNewContextOnEmit ( bool  CloneToNewContextOnEmit )

inline

Sets the CloneToNewContextOnEmit flag (false by default).

When set, IR modules added to this layer will be cloned on to a new context before emit is called. This can be used by clients who want to load all IR using one LLVMContext (to save memory via type and constant uniquing), but want to move Modules to fresh contexts before compiling them to enable concurrent compilation. Single threaded clients, or clients who load every module on a new context, need not set this.
