	Return the llvm::Value * corresponding to the privateVar that is being privatized. It isn't always as simple as looking up moduleTranslation with privateVar. For instance, in case of an allocatable, the descriptor for the allocatable is privatized. This descriptor is mapped using an MapInfoOp. So, this function will return a pointer to the llvm::Value corresponding to the block argument for the mapped descriptor.
static llvm::Value *	materializeRegionArgValue (llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation, BlockArgument regionArg, llvm::Value *value)
static llvm::Expected< llvm::Value * >	initPrivateVar (llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation, omp::PrivateClauseOp &privDecl, llvm::Value *nonPrivateVar, BlockArgument &blockArg, llvm::Value *llvmPrivateVar, llvm::BasicBlock *privInitBlock, llvm::DenseMap< Value, Value > *mappedPrivateVars=nullptr)
	Initialize a single (first)private variable. You probably want to use allocateAndInitPrivateVars instead of this. This returns the private variable which has been initialized. This variable should be mapped before constructing the body of the Op.
static llvm::Expected< llvm::Value * >	initPrivateVar (llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation, omp::PrivateClauseOp &privDecl, Value mlirPrivVar, BlockArgument &blockArg, llvm::Value *llvmPrivateVar, llvm::BasicBlock *privInitBlock, llvm::DenseMap< Value, Value > *mappedPrivateVars=nullptr)
	Version of initPrivateVar which looks up the nonPrivateVar from mlirPrivVar.
static llvm::Error	initPrivateVars (llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation, PrivateVarsInfo &privateVarsInfo, llvm::DenseMap< Value, Value > *mappedPrivateVars=nullptr)
template<typename T>
static llvm::Expected< llvm::BasicBlock * >	allocatePrivateVars (T op, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation, PrivateVarsInfo &privateVarsInfo, const llvm::OpenMPIRBuilder::InsertPointTy &allocaIP, llvm::DenseMap< Value, Value > *mappedPrivateVars=nullptr)
	Allocate and initialize delayed private variables. Returns the basic block which comes after all of these allocations. llvm::Value * for each of these private variables are populated in llvmPrivateVars.
static bool	opIsInSingleThread (mlir::Operation *op)
	This can't always be determined statically, but when we can, it is good to avoid generating compiler-added barriers which will deadlock the program.
static LogicalResult	copyFirstPrivateVars (mlir::Operation *op, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation, SmallVectorImpl< llvm::Value * > &moldVars, ArrayRef< llvm::Value * > llvmPrivateVars, SmallVectorImpl< omp::PrivateClauseOp > &privateDecls, bool insertBarrier, llvm::DenseMap< Value, Value > *mappedPrivateVars=nullptr)

template<typename T>
static LogicalResult	cleanupPrivateVars (T op, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation, Location loc, PrivateVarsInfo &privateVarsInfo)
static bool	constructIsCancellable (Operation *op)

static llvm::Value *	emitTaskReductionInitCall (ArrayRef< omp::DeclareReductionOp > redDecls, ArrayRef< llvm::Value * > origPtrs, StringRef helperNamePrefix, llvm::IRBuilderBase &builder, llvm::OpenMPIRBuilder::InsertPointTy allocaIP, LLVM::ModuleTranslation &moduleTranslation, bool isModifier, bool isWorksharing)
	Emit the per-taskgroup task_reduction descriptor array and the __kmpc_taskred_init runtime call. origPtrs holds the LLVM values for the original (shared) variables, one per declaration in redDecls. builder must be set to the point at which the descriptor stores and the init call should be emitted; the descriptor array itself is allocated at allocaIP. helperNamePrefix is used to disambiguate the generated init/combiner helper symbol names between taskgroup and taskloop callers.
static void	emitTaskReductionModifierFini (bool isWorksharing, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation)
	Emits __kmpc_task_reduction_modifier_fini(loc, gtid, is_ws) at the current builder insertion point, closing the task-reduction scope opened by the task reduction modifier on a parallel or worksharing construct.
static LogicalResult	convertOmpSections (Operation &opInst, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation)
static LogicalResult	convertOmpScope (omp::ScopeOp &scopeOp, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation)
	Converts an OpenMP scope construct into LLVM IR.
static LogicalResult	convertOmpSingle (omp::SingleOp &singleOp, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation)
	Converts an OpenMP single construct into LLVM IR using OpenMPIRBuilder.

static llvm::omp::RTLDependenceKindTy	convertDependKind (mlir::omp::ClauseTaskDepend kind)
static void	buildDependDataLocator (std::optional< ArrayAttr > dependKinds, OperandRange dependVars, LLVM::ModuleTranslation &moduleTranslation, SmallVectorImpl< llvm::OpenMPIRBuilder::DependData > &dds)
static void	pushCancelFinalizationCB (SmallVectorImpl< llvm::UncondBrInst * > &cancelTerminators, llvm::IRBuilderBase &llvmBuilder, llvm::OpenMPIRBuilder &ompBuilder, mlir::Operation *op, llvm::omp::Directive cancelDirective)
	Shared implementation of a callback which adds a termiator for the new block created for the branch taken when an openmp construct is cancelled. The terminator is saved in cancelTerminators. This callback is invoked only if there is cancellation inside of the taskgroup body. The terminator will need to be fixed to branch to the correct block to cleanup the construct.
static void	popCancelFinalizationCB (const ArrayRef< llvm::UncondBrInst * > cancelTerminators, llvm::OpenMPIRBuilder &ompBuilder, const llvm::OpenMPIRBuilder::InsertPointTy &afterIP)
	If we cancelled the construct, we should branch to the finalization block of that construct. OMPIRBuilder structures the CFG such that the cleanup block is immediately before the continuation block. Now this finalization has been created we can fix the branch.
static void	storeAffinityEntry (llvm::IRBuilderBase &builder, llvm::OpenMPIRBuilder &ompBuilder, llvm::Value *affinityList, llvm::Value *index, llvm::Value *addr, llvm::Value *len)
static void	fillAffinityLocators (Operation::operand_range affinityVars, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation, llvm::Value *affinityList)

static mlir::LogicalResult	fillIteratorLoop (mlir::omp::IteratorOp itersOp, llvm::IRBuilderBase &builder, mlir::LLVM::ModuleTranslation &moduleTranslation, IteratorInfo &iterInfo, llvm::StringRef loopName, IteratorStoreEntryTy genStoreEntry)
static mlir::LogicalResult	buildAffinityData (mlir::omp::TaskOp &taskOp, llvm::IRBuilderBase &builder, mlir::LLVM::ModuleTranslation &moduleTranslation, llvm::OpenMPIRBuilder::AffinityData &ad)
static mlir::LogicalResult	buildDependData (OperandRange dependVars, std::optional< ArrayAttr > dependKinds, OperandRange dependIterated, std::optional< ArrayAttr > dependIteratedKinds, llvm::IRBuilderBase &builder, mlir::LLVM::ModuleTranslation &moduleTranslation, llvm::OpenMPIRBuilder::DependenciesInfo &taskDeps)
static LogicalResult	convertOmpTaskOp (omp::TaskOp taskOp, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation)
	Converts an OpenMP task construct into LLVM IR using OpenMPIRBuilder.
static LogicalResult	convertOmpTaskloopWrapperOp (omp::TaskloopWrapperOp loopWrapperOp, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation)
	The correct entry point is convertOmpTaskloopContextOp. This gets called whilst lowering the body of the taskloop context (i.e. the task function).
static llvm::Expected< llvm::Value * >	lookupOrTranslatePureValue (Value value, LLVM::ModuleTranslation &moduleTranslation, llvm::IRBuilderBase &builder)
	Look up the given value in the mapping, and if it's not there, translate its defining operation at the current builder insertion point. Only pure, regionless operations are supported because the same operation will later be translated again when the taskloop body itself is lowered.
static llvm::Error	computeTaskloopBounds (omp::LoopNestOp loopOp, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation, llvm::Value *&lbVal, llvm::Value *&ubVal, llvm::Value *&stepVal)
static LogicalResult	convertOmpTaskloopContextOp (omp::TaskloopContextOp contextOp, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation)
static llvm::Function *	emitTaskReductionInitFn (omp::DeclareReductionOp decl, StringRef baseName, LLVM::ModuleTranslation &moduleTranslation)
	Build an outlined init helper for a task_reduction declare_reduction op. Signature: void(ptr priv, ptr orig). For non-byref reductions, the init region's mold argument is mapped following the same rule as the regular reduction path (mapInitializationArgs): a non-pointer mold loads the value from orig, while a pointer-typed mold receives orig directly. The yielded value is stored into priv.
static llvm::Function *	emitTaskReductionCombFn (omp::DeclareReductionOp decl, StringRef baseName, LLVM::ModuleTranslation &moduleTranslation)
	Build an outlined combiner helper for a task_reduction declare_reduction op. Signature: void(ptr lhs, ptr rhs). For non-byref reductions, the values at *lhs and *rhs are loaded, fed into the combiner region, and the yielded scalar is stored back into *lhs.
static LogicalResult	convertOmpTaskgroupOp (omp::TaskgroupOp tgOp, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation)
	Converts an OpenMP taskgroup construct into LLVM IR using OpenMPIRBuilder.

static LogicalResult	convertOmpCancellationPoint (omp::CancellationPointOp op, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation)
static LogicalResult	convertOmpThreadprivate (Operation &opInst, llvm::IRBuilderBase &builder, LLVM::ModuleTranslation &moduleTranslation)

static void	collectMapDataFromMapOperands (MapInfoData &mapData, SmallVectorImpl< Value > &mapVars, LLVM::ModuleTranslation &moduleTranslation, DataLayout &dl, llvm::IRBuilderBase &builder, ArrayRef< Value > useDevPtrOperands={}, ArrayRef< Value > useDevAddrOperands={}, ArrayRef< Value > hasDevAddrOperands={})

static std::vector< llvm::Value * >	calculateBoundsOffset (LLVM::ModuleTranslation &moduleTranslation, llvm::IRBuilderBase &builder, bool isArrayTy, OperandRange bounds)
	This function calculates the array/pointer offset for map data provided with bounds operations, e.g. when provided something like the following:
static void	getAsIntegers (ArrayAttr values, llvm::SmallVector< int64_t > &ints)
static void	getOverlappedMembers (llvm::SmallVectorImpl< size_t > &overlapMapDataIdxs, omp::MapInfoOp parentOp)

	This function handles the insertion of a single item of map data from MapInfoData into the OMPIRBuilder's MapInfo list. Utilising this function means the map being inserted can be treated as a non-parent map entity, if the memberOfFlag is set then the map being inserted is treated as a member map of a larger entity. The insertion into the MapInfo list of the OMPIRBuilder can vary based on a number of factors, such as if it's a ref_ptr or ref_ptee map, if it's a member of a record, what construct the map belongs to and the various map type bit flags that are set for the map.

calculateBoundsOffset()

std::vector< llvm::Value * > calculateBoundsOffset ( LLVM::ModuleTranslation & moduleTranslation, llvm::IRBuilderBase & builder, bool isArrayTy, OperandRange bounds )

static

This function calculates the array/pointer offset for map data provided with bounds operations, e.g. when provided something like the following:

Fortran map(tofrom: array(2:5, 3:2))

We must calculate the initial pointer offset to pass across, this function performs this using bounds.

TODO/WARNING: This only supports Fortran's column major indexing currently as is noted in the note below and comments in the function, we must extend this function when we add a C++ frontend. NOTE: which while specified in row-major order it currently needs to be flipped for Fortran's column order array allocation and access (as opposed to C++'s row-major, hence the backwards processing where order is important). This is likely important to keep in mind for the future when we incorporate a C++ frontend, both frontends will need to agree on the ordering of generated bounds operations (one may have to flip them) to make the below lowering frontend agnostic. The offload size calcualtion may also have to be adjusted for C++.

static

Emit the per-taskgroup task_reduction descriptor array and the __kmpc_taskred_init runtime call. origPtrs holds the LLVM values for the original (shared) variables, one per declaration in redDecls. builder must be set to the point at which the descriptor stores and the init call should be emitted; the descriptor array itself is allocated at allocaIP. helperNamePrefix is used to disambiguate the generated init/combiner helper symbol names between taskgroup and taskloop callers.

When isModifier is false, emits __kmpc_taskred_init and returns the ptr value it produces (the taskgroup reduction handle). When isModifier is true, emits __kmpc_taskred_modifier_init instead to open a task-reduction scope for a parallel or worksharing construct, passing isWorksharing as the runtime is_ws argument. Returns null on failure.

Only the non-byref form is handled here. Byref reductions have already been rejected by checkImplementationStatus.

static

This function handles the insertion of a single item of map data from MapInfoData into the OMPIRBuilder's MapInfo list. Utilising this function means the map being inserted can be treated as a non-parent map entity, if the memberOfFlag is set then the map being inserted is treated as a member map of a larger entity. The insertion into the MapInfo list of the OMPIRBuilder can vary based on a number of factors, such as if it's a ref_ptr or ref_ptee map, if it's a member of a record, what construct the map belongs to and the various map type bit flags that are set for the map.

Shared implementation of a callback which adds a termiator for the new block created for the branch taken when an openmp construct is cancelled. The terminator is saved in cancelTerminators.
