Member Function Documentation

◆ createDeclareReduction()

template<typename OpType>
OpType Fortran::lower::omp::ReductionProcessor::createDeclareReduction ( AbstractConverter & builder,
llvm::StringRef reductionOpName,
const ReductionIdentifier redId,
mlir::Type type,
mlir::Location loc,
bool isByRef )
static

Creates an OpenMP reduction declaration and inserts it into the provided symbol table. The declaration has a constant initializer with the neutral value initValue, and the reduction combiner carried over from reduce. TODO: add atomic region.

◆ createDeclareReductionHelper()

template<typename DeclareRedType>
DeclareRedType Fortran::lower::omp::ReductionProcessor::createDeclareReductionHelper ( AbstractConverter & converter,
llvm::StringRef reductionOpName,
mlir::Type type,
mlir::Location loc,
bool isByRef,
GenCombinerCBTy genCombinerCB,
GenInitValueCBTy genInitValueCB )
static

Creates an OpenMP reduction declaration and inserts it into the provided symbol table. The init and combiner regions are generated by the callback functions genCombinerCB and genInitValueCB.

◆ getOperationIdentity()

int Fortran::lower::omp::ReductionProcessor::getOperationIdentity ( ReductionIdentifier redId,
mlir::Location loc )
static

This function returns the identity value of the operator reductionOpName. For example: 0 + x = x, 1 * x = x

◆ processReductionArguments()

template<typename OpType, typename RedOperatorListTy>
bool Fortran::lower::omp::ReductionProcessor::processReductionArguments ( mlir::Location currentLocation,
lower::AbstractConverter & converter,
const RedOperatorListTy & redOperatorList,
llvm::SmallVectorImpl< mlir::Value > & reductionVars,
llvm::SmallVectorImpl< bool > & reduceVarByRef,
llvm::SmallVectorImpl< mlir::Attribute > & reductionDeclSymbols,
const llvm::SmallVectorImpl< const semantics::Symbol * > & reductionSymbols )
static

Creates a reduction declaration and associates it with an OpenMP block directive.
