CanQualType getSizeType() const

Return the unique type for "size_t" (C99 7.17), defined in <stddef.h>.

uint64_t getTypeSize(QualType T) const

Return the size of the specified (complete) type T, in bits.

@ AS_HLSLAnnotation

<vardecl> : <annotation>

Kind getParsedKind() const

RAII class that helps handle the parsing of an open/close delimiter pair, such as braces { ....

Decl - This represents one declaration (or definition), e.g.

SourceLocation getLocation() const

static FixItHint CreateReplacement(CharSourceRange RemoveRange, StringRef Code)

Create a code modification hint that replaces the given source range with the given code string.

One of these records is kept for each identifier that is lexed.

StringRef getName() const

Return the actual identifier string.

static IntegerLiteral * Create(const ASTContext &C, const llvm::APInt &V, QualType type, SourceLocation l)

Returns a new integer literal with value 'V' and type 'type'.

Wrapper for void* pointer.

ParsedAttributes - A collection of parsed attributes.

ParsedAttr * addNew(IdentifierInfo *attrName, SourceRange attrRange, IdentifierInfo *scopeName, SourceLocation scopeLoc, ArgsUnion *args, unsigned numArgs, ParsedAttr::Form form, SourceLocation ellipsisLoc=SourceLocation())

Add attribute with expression arguments.

Parser - This implements a parser for the C family of languages.

SourceLocation ConsumeToken()

ConsumeToken - Consume the current 'peek token' and lex the next one.

OpaquePtr< DeclGroupRef > DeclGroupPtrTy

Scope * getCurScope() const

bool SkipUntil(tok::TokenKind T, SkipUntilFlags Flags=static_cast< SkipUntilFlags >(0))

SkipUntil - Read tokens until we get to the specified token, then consume it (unless StopBeforeMatch ...

@ StopAtSemi

Stop skipping at semicolon.

Engages in a tight little dance with the lexer to efficiently preprocess tokens.

IdentifierInfo * getIdentifierInfo(StringRef Name) const

Return information about the specified preprocessor identifier token.

A (possibly-)qualified type.

@ DeclScope

This is a scope that can contain a declaration.

void ActOnFinishBuffer(Decl *Dcl, SourceLocation RBrace)

Encodes a location in the source.

SourceLocation getLocWithOffset(IntTy Offset) const

Return a source location with the specified offset from this SourceLocation.

A trivial tuple used to represent a source range.

Token - This structure provides full information about a lexed token.

IdentifierInfo * getIdentifierInfo() const

SourceLocation getEndLoc() const

SourceLocation getLocation() const

Return a source location identifier for the specified offset in the current file.

unsigned getLength() const

bool is(tok::TokenKind K) const

is/isNot - Predicates to check if this token is a specific kind, as in "if (Tok.is(tok::l_brace)) {....

bool isNot(tok::TokenKind K) const

const char * getLiteralData() const

getLiteralData - For a literal token (numeric constant, string, etc), this returns a pointer to the s...

The JSON file list parser is used to communicate input to InstallAPI.

llvm::PointerUnion< Expr *, IdentifierLoc * > ArgsUnion

A union of the various pointer types that can be passed to an ParsedAttr as an argument.

@ Result

The result type of a method or function.

const FunctionProtoType * T

Wraps an identifier and optional source location for the identifier.

static IdentifierLoc * create(ASTContext &Ctx, SourceLocation Loc, IdentifierInfo *Ident)
