Member Data Documentation
◆ AtomicReductionGen
| ReductionGenAtomicCBTy 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.

◆ ByRefAllocatedType
| Type* llvm::OpenMPIRBuilder::ReductionInfo::ByRefAllocatedType |
For by-ref reductions, we need to keep track of 2 extra types that are potentially different:
- The allocated type is the type of the storage allocated by the reduction op's alloc region. For example, for allocatables and arrays, this type would be the descriptor/box struct.

◆ ByRefElementType
| Type* llvm::OpenMPIRBuilder::ReductionInfo::ByRefElementType |
- The by-ref element type is the type of the actual storage needed for the data of the allocatable or array. For example, an float allocatable of would need some float storage to store intermediate reduction results.

Referenced by llvm::OpenMPIRBuilder::createReductionsGPU(), ReductionInfo(), and ReductionInfo().
◆ ElementType
| Type* llvm::OpenMPIRBuilder::ReductionInfo::ElementType |
Reduction element type, must match pointee type of variable.
For by-ref reductions, this would be just an opaque ptr.

◆ EvaluationKind
| EvalKind llvm::OpenMPIRBuilder::ReductionInfo::EvaluationKind |
Reduction evaluation kind - scalar, complex or aggregate.
Definition at line 1742 of file OMPIRBuilder.h.
Referenced by ReductionInfo(), and ReductionInfo().
◆ PrivateVariable
| Value* llvm::OpenMPIRBuilder::ReductionInfo::PrivateVariable |
Thread-private partial reduction variable.

◆ ReductionGen
| ReductionGenCBTy 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.

◆ ReductionGenClang
| ReductionGenClangCBTy llvm::OpenMPIRBuilder::ReductionInfo::ReductionGenClang |
Clang 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.
