		unsigned	Version
	)

Can directive D, under some circumstances, create a private copy of a variable in given OpenMP version?

◆ isValidTraitPropertyForTraitSetAndSelector()

bool llvm::omp::isValidTraitPropertyForTraitSetAndSelector	(	TraitProperty	Property,
		TraitSelector	Selector,
		TraitSet	Set
	)

Return true if Property can be nested in Selector and Set.

Definition at line 588 of file OMPContext.cpp.

References llvm_unreachable.

◆ isValidTraitSelectorForTraitSet()

bool llvm::omp::isValidTraitSelectorForTraitSet	(	TraitSelector	Selector,
		TraitSet	Set,
		bool &	AllowsTraitScore,
		bool &	RequiresProperty
	)

}

Return true if Selector can be nested in Set. Also sets AllowsTraitScore and RequiresProperty to true/false if the user can specify a score for properties in Selector and if the Selector requires at least one property.

◆ isVariantApplicableInContext()

bool llvm::omp::isVariantApplicableInContext	(	const VariantMatchInfo &	VMI,
		const OMPContext &	Ctx,
		bool	DeviceOrImplementationSetOnly = `false`
	)

Return true if VMI is applicable in Ctx, that is, all traits required by VMI are available in the OpenMP context Ctx.

If DeviceOrImplementationSetOnly is true, only the device and implementation selector set, if present, are checked. Note that we still honor extension traits provided by the user.

◆ listOpenMPContextTraitProperties()

std::string llvm::omp::listOpenMPContextTraitProperties	(	TraitSet	Set,

	)

Return a string listing all trait properties for Set and Selector.

◆ listOpenMPContextTraitSelectors()

std::string llvm::omp::listOpenMPContextTraitSelectors ( TraitSet Set )

Return a string listing all trait selectors for Set.
