2012-11-14Accept and pass arguments to __unknown_anytype in argumentJohn McCall
positions of Objective-C methods. It is possible to recover a lot of type information about Objective-C methods from the reflective metadata for their implementations. This information is not rich when it comes to struct types, however, and it is not possible to produce a type in the debugger's round-tripped AST which will really do anything useful during type-checking. Therefore we allow __unknown_anytype in these positions, which essentially disables type-checking for that argument. We infer the parameter type to be the unqualified type of the argument expression unless that expression is an explicit cast, in which case it becomes the type-as-written of that cast. rdar://problem/12565338 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167896 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-07PR13552: Fix the end location of a CXXNewExpr.David Blaikie
Spent longer than reasonable looking for a nice way to test this & decided to give up for now. Open to suggestions/requests.

2012-10-21PR14141 (part of DR1351): An implicitly-deduced "any" exception specificationRichard Smith

2012-10-21Unrevert r166268, reverted in r166272, with a fix for the issue which NickRichard Smith
found: if an overloaded operator& is present before a template definition, the expression &T::foo is represented as a CXXOperatorCallExpr, not as a UnaryOperator, so we didn't notice that it's permitted to reference a non-static data member of an unrelated class. While investigating this, I discovered another problem in this area: we are treating template default arguments as unevaluated contexts during substitution, resulting in performing incorrect checks for uses of non-static data members in C++11. That is not fixed by this patch (I'll look into this soon; it's related to the failure to correctly instantiate constexpr function templates), but was resulting in this bug not firing in C++11 mode (except with -Wc++98-compat).

2012-10-10Move Sema::PropertyIfSetterOrGetter to ObjCMethodDecl::findPropertyDecl.Jordan Rose
Then, switch users of PropertyIfSetterOrGetter and LookupPropertyDecl (the latter by name) over to findPropertyDecl. This actually makes -Wreceiver-is-weak a bit stronger than it was before. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165628 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10Change Sema::PropertyIfSetterOrGetter to make use of isPropertyAccessor.Jordan Rose
Old algorithm: 1. See if the name looks like a getter or setter. 2. Use the name to look up a property in the current ObjCContainer and all its protocols. 3. If the current container is an interface, also look in all categories and superclasses (and superclass categories, and so on). New algorithm: 1. See if the method is marked as a property accessor. If so, look through all properties in the current container and find one that has a matching selector. 2. Find all overrides of the method using ObjCMethodDecl's getOverriddenMethods. This collects methods in superclasses and protocols (as well as superclass categories, which isn't really necessary), and checks if THEY are accessors. This part is not done recursively, since getOverriddenMethods is already recursive. This lets us handle getters and setters that do not match the property names. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165627 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-26Fix an edge case of mangling involving the combination of a lambda and typeid.Eli Friedman
typeid (and a couple other non-standard places where we can transform an unevaluated expression into an evaluated expression) is special because it introduces an an expression evaluation context, which conflicts with the mechanism to compute the current lambda mangling context. PR12123. I would appreciate if someone would double-check that we get the mangling correct with this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164658 91177308-0d34-0410-b5e6-96231b3b80d8

but can be dereferenced to form an expression which does have viable begin/end functions, then typo-correct the range, even if something else goes wrong with the statement (such as inaccessible begin/end or the wrong type of loop variable).

nested names as id-expressions, using the annot_primary_expr annotation, where possible. This removes some redundant lookups, and also allows us to typo-correct within tentative parsing, and to carry on disambiguating past an identifier which we can determine will fail lookup as both a type and as a non-type, allowing us to disambiguate more declarations (and thus offer improved error recovery for such cases). This also introduces to the parser the notion of a tentatively-declared name, which is an identifier which we *might* have seen a declaration for in a tentative parse (but only if we end up disambiguating the tokens as a declaration). This is necessary to correctly disambiguate cases where a variable is used within its own initializer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162159 91177308-0d34-0410-b5e6-96231b3b80d8
