2008-12-10Use a scoped object to manage entry/exit from a parser scope rather than ↵Douglas Gregor
explicitly calling EnterScope/ExitScope git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60830 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-10Modify the move emulation according to the excellent design of Howard ↵Sebastian Redl
Hinnant. Makes for much nicer syntax when smart pointers are used consistently. Also, start converting internal argument passing of Parser to smart pointers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60809 91177308-0d34-0410-b5e6-96231b3b80d8

variables. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60761 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-06Add support for calls to dependent names within templates, e.g.,Douglas Gregor
template<typename T> void f(T x) { g(x); // g is a dependent name, so don't even bother to look it up g(); // error: g is not a dependent name } Note that when we see "g(", we build a CXXDependentNameExpr. However, if none of the call arguments are type-dependent, we will force the resolution of the name "g" and replace the CXXDependentNameExpr with its result. GCC actually produces a nice error message when you make this mistake, and even offers to compile your code with -fpermissive. I'll do the former next, but I don't plan to do the latter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60618 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-02Add better comments to ::new parsing. Thanks to Doug for the review.Sebastian Redl

2008-11-25Use RAII objects to ensure proper destruction of expression and statement ↵Sebastian Redl
AST nodes in the parser in most cases, even on error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60057 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-23make the 'to match this' diagnostic a note.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59921 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-23Convert IdentifierInfo's to be printed the same as DeclarationNames Chris Lattner
with implicit quotes around them. This has a bunch of follow-on effects and requires tweaking to a whole lot of code. This causes a regression in two tests (xfailed) by causing it to emit things like: Line 10: duplicate interface declaration for category 'MyClass1' ('Category1') instead of: Line 10: duplicate interface declaration for category 'MyClass1(Category1)' I will fix this in a follow-up commit. As part of this, I had to start switching stuff to use ->getDeclName() instead of Decl::getName() for consistency. This is good, but I was planning to do this as an independent patch. There will be several follow-on patches to clean up some of the mess, but this patch is already too big. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59917 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21Implementation of new and delete parsing and sema.Sebastian Redl
This version uses VLAs to represent arrays. I'll try an alternative way next, but I want this safe first. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59835 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Support overloading of the subscript operator[], including support forDouglas Gregor
built-in operator candidates. Test overloading of '&' and ','. In C++, a comma expression is an lvalue if its right-hand subexpression is an lvalue. Update Expr::isLvalue accordingly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59643 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Fix <rdar://problem/6150376> [sema] crash on invalid message send.Steve Naroff
The core fix in Sema::ActOnClassMessage(). All the other changes have to do with passing down the SourceLocation for the receiver (to properly position the cursor when producing an error diagnostic). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59639 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-19Added operator overloading for unary operators, post-increment, andDouglas Gregor
post-decrement, including support for generating all of the built-in operator candidates for these operators. C++ and C have different rules for the arguments to the builtin unary '+' and '-'. Implemented both variants in Sema::ActOnUnaryOp. In C++, pre-increment and pre-decrement return lvalues. Update Expr::isLvalue accordingly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59638 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-18Change a couple of the Parser::Diag methods to return DiagnosticInfoChris Lattner
and let the clients push whatever they want into the DiagnosticInfo instead of hard coding a few forms. Also switch various clients to use Diag(Tok, ...) instead of Diag(Tok.getLocation(), ...) as the canonical form to simplify the code a bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59509 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-11Introduce a single AST node SizeOfAlignOfExpr for all sizeof and alignof ↵Sebastian Redl
expressions, both of values and types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59057 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-11Implement C++ 'typeid' parsing and sema.Sebastian Redl
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59042 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-08Implement support for C++ nested-name-specifiers ('foo::bar::x') in the ↵Argyrios Kyrtzidis
Parser side. No Sema functionality change, just the signatures of the Action/Sema methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58913 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-06Initial, rudimentary implementation of operator overloading for binaryDouglas Gregor
operators. For example, one can now write "x + y" where x or y is a class or enumeration type, and Clang will perform overload resolution for "+" based on the overloaded operators it finds. The other kinds of overloadable operators in C++ will follow this same approach. Three major issues remain: 1) We don't find member operators 2) Since we don't have user-defined conversion operators, we can't call any of the built-in overloaded operators in C++ [over.built]. 3) Once we've done the semantic checks, we drop the overloaded operator on the floor; it doesn't get into the AST at all. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58821 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-06Parsing, ASTs, and semantic analysis for the declaration of overloadedDouglas Gregor
operators in C++. Overloaded operators can be called directly via their operator-function-ids, e.g., "operator+(foo, bar)", but we don't yet implement the semantics of operator overloading to handle, e.g., "foo + bar". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58817 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-24-Add support for cv-qualifiers after function declarators.Argyrios Kyrtzidis
-Add withConst/withVolatile/withRestrict methods to QualType class, that return the QualType plus the respective qualifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58120 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-10Final phase of converting BlockDecls over to DeclContext. This is ↵Steve Naroff
unfortunately a largish/complex diff, however it was necessry to pass all the current block tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57337 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
2008-09-16Remove support for BlockExprExpr. For example...Steve Naroff
^(expression) or ^(int arg1, float arg2)(expression) ...is no longer supported. All block literals now require a compound statement. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56257 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28Add parser/action support for block literal expressions.Steve Naroff
Parser support for blocks is almost complete...just need to add support for the __block() storage class qualifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55495 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

2008-08-16Put (argument)-expression-list parsing in a separate function so that it can ↵Argyrios Kyrtzidis
be re-used. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54851 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-16C++ casts, (static_cast. dynamic_cast, etc.) can have postfix-expression pieces.Argyrios Kyrtzidis
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54850 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-16Move handling of postfix-expression suffixes out of ParseCXXThis and into ↵Argyrios Kyrtzidis
ParseCastExpression. No functionality change, this follows the convention of how postfix-expressions are handled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54849 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-16Add 'this' in the comments of Parser::ParseCastExpression to indicate that ↵Argyrios Kyrtzidis
it is handled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53665 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-09Simplify the parser a bit by looking at the next token without consuming it ↵Argyrios Kyrtzidis
(by Preprocessor::LookNext): -Remove ParseExpressionWithLeadingIdentifier and ParseAssignmentExprWithLeadingIdentifier. -Separate ParseLabeledStatement from ParseIdentifierStatement. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53376 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-24Add parsing support for C++ classes.Argyrios Kyrtzidis
Note that Parser::ParseCXXMemberSpecification is temporarily disabled until the Sema support is in place. Once ParseCXXMemberSpecification is enabled, the Parser/cxx-class.cpp test will pass. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52694 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-02handle the full assignment-expression grammar when using an Chris Lattner
objc message send in an initializer expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51882 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-09Don't call into objc front-end when not parsing objc code. This avoidsChris Lattner
crashes because objc types aren't set up right. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50884 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-06Use token lookahead to simplify some code that is rarely executed.Chris Lattner
Since it is rare, the cost is not significant and we enjoy the simplification. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49263 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8
