Detailed Description

Helper data structure representing the traits in a match clause of an declare variant or metadirective.

The outer level is an ordered collection of selector sets, each with an associated kind and an ordered collection of selectors. A selector has a kind, an optional score/condition, and an ordered collection of properties.

◆ OMPTraitInfo()

OMPTraitInfo::OMPTraitInfo ( StringRef MangledName )

Reconstruct a (partial) OMPTraitInfo object from a mangled name.

◆ anyScoreOrCondition()

bool clang::OMPTraitInfo::anyScoreOrCondition ( llvm::function_ref< bool(Expr *&, bool)> Cond )

◆ getAsVariantMatchInfo()

void OMPTraitInfo::getAsVariantMatchInfo	(	ASTContext &	ASTCtx,
		llvm::omp::VariantMatchInfo &	VMI ) const

Create a variant match info object from this trait info object.

While the former is a flat representation the actual main difference is that the latter uses clang::Expr to store the score/condition while the former is independent of clang. Thus, expressions and conditions are evaluated in this method.
