Create()

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

static

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

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.
NumLoops	Number of affected loops (the flatten depth: the argument of the 'depth' clause, or 2 if omitted).
AssociatedStmt	The outermost associated loop.
TransformedStmt	The flattened loop, or nullptr in dependent contexts.
PreInits	Helper preinits statements for the loop nest.
Finals	Updates to the original loop variables after the loop.

CreateEmpty()

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

static

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

Parameters

C	Context of the AST.
NumClauses	Number of clauses to allocate.
NumLoops	Number of associated loops to allocate.
