Member Data Documentation

AtomicReductionGen

AtomicReductionGenTy llvm::OpenMPIRBuilder::ReductionInfo::AtomicReductionGen

Callback for generating the atomic reduction body, may be null.

The IR produced by this will be used to atomically combine two values during reduction. If null, the implementation will use the non-atomic version along with the appropriate synchronization mechanisms.

ElementType

Type* llvm::OpenMPIRBuilder::ReductionInfo::ElementType

Reduction element type, must match pointee type of variable.

Definition at line 1261 of file OMPIRBuilder.h.

Referenced by llvm::OpenMPIRBuilder::createReductions().

PrivateVariable

Value* llvm::OpenMPIRBuilder::ReductionInfo::PrivateVariable

Thread-private partial reduction variable.

ReductionGen

ReductionGenTy llvm::OpenMPIRBuilder::ReductionInfo::ReductionGen

Callback for generating the reduction body.

The IR produced by this will be used to combine two values in a thread-safe context, e.g., under lock or within the same thread, and therefore need not be atomic.

Variable

Value* llvm::OpenMPIRBuilder::ReductionInfo::Variable

Reduction variable of pointer type.
