class LabelDecl

Declaration

class LabelDecl : public NamedDecl { /* full declaration omitted */ };

Description

Represents the declaration of a label. Labels also have a corresponding LabelStmt, which indicates the position that the label was defined at. For normal labels, the location of the decl is the same as the location of the statement. For GNU local labels (__label__), the decl location is where the __label__ is.

Member Variables

private clang::LabelStmt* TheStmt

private llvm::StringRef MSAsmName

private bool MSAsmNameResolved = false

private clang::SourceLocation LocStart

For normal labels, this is the same as the main declaration label, i.e., the location of the identifier; for GNU local labels, this is the location of the __label__ keyword.
