2008-10-06Implement support for C++ direct initializers in declarations, e.g. "int x(1);".Argyrios Kyrtzidis
This is how this kind of initializers appear in the AST: -The Init expression of the VarDecl is a functional type construction (of the VarDecl's type). -The new VarDecl::hasCXXDirectInitializer() returns true. e.g, for "int x(1);": -VarDecl 'x' has Init with expression "int(1)" (CXXFunctionalCastExpr). -hasCXXDirectInitializer() of VarDecl 'x' returns true. A major benefit is that clients that don't particularly care about which exactly form was the initializer can handle both cases without special case code. Note that codegening works now for "int x(1);" without any changes to CodeGen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57178 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-05Handle ambiguities between expressions and type-ids that occur inside ↵Argyrios Kyrtzidis
parentheses, e.g.: sizeof(int()) -> "int()" is type-id sizeof(int()+1) -> "int()+1" is expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57131 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-05Found a subtle bug caused by an implicit enum-to-bool conversion (of the ↵Argyrios Kyrtzidis
TentativeParsingResult enum). This was the motivation of the following changes: -'TentativeParsingResult' enum is replaced by a 'TPResult' class that basically encapsulates the enum. -TPR_true, TPR_false, TPR_ambiguous, and TPR_error enum constants are replaced by TPResult::True(), TPResult::False(), etc. calls that return a TPResult object. -Also fixed the subtle bug in Parser::isCXXFunctionDeclarator (caught by the above changes as a compilation error). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57125 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-22Add support for C++'s "type-specifier ( expression-list )" expression:Argyrios Kyrtzidis
-The Parser calls a new "ActOnCXXTypeConstructExpr" action. -Sema, depending on the type and expressions number: -If the type is a class, it will treat it as a class constructor. [TODO] -If there's only one expression (i.e. "int(0.5)" ), creates a new "CXXFunctionalCastExpr" Expr node -If there are no expressions (i.e "int()" ), creates a new "CXXZeroInitValueExpr" Expr node. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55177 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-16Declarator class considers DeclSpec as immutable; ↵Argyrios Kyrtzidis
Declarator::getMutableDeclSpec should be used rarely and with care. Have Declarator accept and use a 'const DeclSpec &', instead of 'DeclSpec &', to make DeclSpec's immutability more explicit. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54839 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-14Change Parser & Sema to use interned "super" for comparions.Daniel Dunbar
- Added as private members for each because it is not clear where to put the common definition. Perhaps the IdentifierInfos all of these "pseudo-keywords" should be collected into one place (this would KnownFunctionIDs and Objective-C property IDs, for example). Remove Token::isNamedIdentifier. - There isn't a good reason to use strcmp when we have interned strings, and there isn't a good reason to encourage clients to do so. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54794 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-05Add more Parser/Sema support for GCC asm-label extension.Daniel Dunbar
- ActOnDeclarator now takes an additional parameter which is the AsmLabel if used. Its unfortunate that this bubbles up this high, but we cannot just lump it in as an attribute without mistakenly *accepting* it as an attribute. - The actual asm-label itself is, however, encoded as an AsmLabelAttr on the FunctionDecl. - Slightly improved parser error recovery on malformed asm-labels. - CodeGen support still missing... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54339 91177308-0d34-0410-b5e6-96231b3b80d8
