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.

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.
