Methods

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

Description

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

Declared at: clang/include/clang/AST/StmtOpenMP.h:5611

Parameters

const clang::ASTContext& C

Context of the AST.

clang::SourceLocation StartLoc

Location of the introducer (e.g. the 'omp' token).

clang::SourceLocation EndLoc

Location of the directive's end (e.g. the tok::eod).

ArrayRef<clang::OMPClause*> Clauses

The directive's clauses.

clang::Stmt* AssociatedStmt

The outermost associated loop.

unsigned int NumGeneratedLoops

clang::Stmt* TransformedStmt

The loop nest after tiling, or nullptr in dependent contexts.

clang::Stmt* PreInits

Helper preinits statements for the loop nest.

¶static clang::OMPUnrollDirective* CreateEmpty(
    const clang::ASTContext& C,
    unsigned int NumClauses)

Description

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

Declared at: clang/include/clang/AST/StmtOpenMP.h:5619

Parameters

const clang::ASTContext& C

Context of the AST.

unsigned int NumClauses

Number of clauses to allocate.

¶OMPUnrollDirective(clang::SourceLocation StartLoc,
                   clang::SourceLocation EndLoc)

Declared at: clang/include/clang/AST/StmtOpenMP.h:5584

Parameters

clang::SourceLocation StartLoc

clang::SourceLocation EndLoc

¶static bool classof(const clang::Stmt* T)

Declared at: clang/include/clang/AST/StmtOpenMP.h:5636

Parameters

const clang::Stmt* T

¶clang::Stmt* getPreInits() const

Description

Return the pre-init statements.

Declared at: clang/include/clang/AST/StmtOpenMP.h:5634

¶clang::Stmt* getTransformedStmt() const

Description

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.

Declared at: clang/include/clang/AST/StmtOpenMP.h:5629

¶void setPreInits(clang::Stmt* PreInits)

Description

Set the pre-init statements.

Declared at: clang/include/clang/AST/StmtOpenMP.h:5590

Parameters

clang::Stmt* PreInits

¶void setTransformedStmt(clang::Stmt* S)

Description

Set the de-sugared statement.

Declared at: clang/include/clang/AST/StmtOpenMP.h:5595

Parameters

clang::Stmt* S
