◆ Create()

OMPUnrollDirective * OMPUnrollDirective::Create	(	const ASTContext &	C,
		SourceLocation	StartLoc,
		SourceLocation	EndLoc,
		ArrayRef< OMPClause * >	Clauses,
		Stmt *	AssociatedStmt,
		unsigned	NumGeneratedTopLevelLoops,
		Stmt *	TransformedStmt,
		Stmt *	PreInits )

static

Create a new AST node representation for '#pragma omp unroll'.

Parameters

C	Context of the AST.
StartLoc	Location of the introducer (e.g. the 'omp' token).
EndLoc	Location of the directive's end (e.g. the tok::eod).
Clauses	The directive's clauses.
AssociatedStmt	The outermost associated loop.
TransformedStmt	The loop nest after tiling, or nullptr in dependent contexts.
PreInits	Helper preinits statements for the loop nest.

◆ CreateEmpty()

OMPUnrollDirective * OMPUnrollDirective::CreateEmpty	(	const ASTContext &	C,
		unsigned	NumClauses )

static

Build an empty '#pragma omp unroll' AST node for deserialization.

Parameters

C	Context of the AST.
NumClauses	Number of clauses to allocate.

◆ getPreInits()

Stmt * OMPUnrollDirective::getPreInits ( ) const

inline

Return the pre-init statements.

Definition at line 5897 of file StmtOpenMP.h.

◆ getTransformedStmt()

Stmt * OMPUnrollDirective::getTransformedStmt ( ) const

inline

Get the de-sugared associated loops after unrolling.

This is only used if the unrolled loop becomes an associated loop of another directive, otherwise the loop is emitted directly using loop transformation metadata. When the unrolled loop cannot be used by another directive (e.g. because of the full clause), the transformed stmt can also be nullptr.
