◆ ParseExpression()

ExprResult Parser::ParseExpression ( TypeCastState isTypeCast = NotTypeCast )

Simple precedence-based parser for binary/ternary operators.

Note: we diverge from the C99 grammar when parsing the assignment-expression production. C99 specifies that the LHS of an assignment operator should be parsed as a unary-expression, but consistency dictates that it be a conditional-expession. In practice, the important thing here is that the LHS of an assignment has to be an l-value, which productions between unary-expression and conditional-expression don't produce. Because we want consistency, we parse the LHS as a conditional-expression, then check for l-value-ness in semantic analysis stages.

Parameters

SS	The nested-name-specifier that preceded this unqualified-id. If non-empty, then we are parsing the unqualified-id of a qualified-id.
ObjectType	if this unqualified-id occurs within a member access expression, the type of the base object whose member is being accessed.
ObjectHadErrors	if this unqualified-id occurs within a member access expression, indicates whether the original subexpressions had any errors. When true, diagnostics for missing 'template' keyword will be supressed.
EnteringContext	whether we are entering the scope of the nested-name-specifier.
AllowDestructorName	whether we allow parsing of a destructor name.
AllowConstructorName	whether we allow parsing a constructor name.
AllowDeductionGuide	whether we allow parsing a deduction guide name.
Result	on a successful parse, contains the parsed unqualified-id.

Returns: true if parsing fails, false otherwise.

◆ SkipMalformedDecl()

void Parser::SkipMalformedDecl ( )

SkipMalformedDecl - Read tokens until we get to some likely good stopping point for skipping past a simple-declaration.

Skip until we reach something which seems like a sensible place to pick up parsing after a malformed declaration.

This will sometimes stop sooner than SkipUntil(tok::r_brace) would, but will never stop later.

◆ SkipUntil() [1/4]

bool Parser::SkipUntil	(	ArrayRef< tok::TokenKind >	Toks,

SkipUntil - Read tokens until we get to the specified token, then consume it (unless no flag StopBeforeMatch).

Because we cannot guarantee that the token will ever occur, this skips to the next token, or to some likely good stopping point. If StopAtSemi is true, skipping will stop at a ';' character.

If SkipUntil finds the specified token, it returns true, otherwise it returns false.

◆ TryAnnotateCXXScopeToken()

Note that this routine emits an error if you call it with ::new or ::delete as the current tokens, so only call it in contexts where these are invalid.

◆ TryAnnotateTypeOrScopeToken()

bool Parser::TryAnnotateTypeOrScopeToken ( ImplicitTypenameContext AllowImplicitTypename = ImplicitTypenameContext::No )

TryAnnotateTypeOrScopeToken - If the current token position is on a typename (possibly qualified in C++) or a C++ scope specifier not followed by a typename, TryAnnotateTypeOrScopeToken will replace one or more tokens with a single annotation token representing the typename or C++ scope respectively.

This simplifies handling of C++ scope specifiers and allows efficient backtracking without the need to re-parse and resolve nested-names and typenames. It will mainly be called when we expect to treat identifiers as typenames (if they are typenames). For example, in C we do not expect identifiers inside expressions to be treated as typenames so it will not be called for expressions in C. The benefit for C/ObjC is that a typename will be annotated and Actions.getTypeName will not be needed to be called again (e.g. getTypeName will not be called twice, once to check whether we have a declaration specifier, and another one to get the actual type inside ParseDeclarationSpecifiers).

This returns true if an error occurred.

Note that this routine emits an error if you call it with ::new or ::delete as the current tokens, so only call it in contexts where these are invalid.

◆ TryAnnotateTypeOrScopeTokenAfterScopeSpec()

bool Parser::TryAnnotateTypeOrScopeTokenAfterScopeSpec	(	CXXScopeSpec &	SS,

Try to annotate a type or scope token, having already parsed an optional scope specifier.

IsNewScope should be true unless the scope specifier was extracted from an existing tok::annot_cxxscope annotation.

An Objective-C object type followed by '<' is a specialization of a parameterized class type or a protocol-qualified type.
