2009-11-04Don't try to check the initialization of fields with dependentDouglas Gregor
types. Fixes PR5352. Fariborz, please review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86031 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-04Switch parsing of using declarations over to ParseUnqualifiedId.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86027 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-03Introduce a new class, UnqualifiedId, that provides a parsedDouglas Gregor
representation of a C++ unqualified-id, along with a single parsing function (Parser::ParseUnqualifiedId) that will parse all of the various forms of unqualified-id in C++. Replace the representation of the declarator name in Declarator with the new UnqualifiedId class, simplifying declarator-id parsing considerably and providing more source-location information to Sema. In the future, I hope to migrate all of the other unqualified-id-parsing code over to this single representation, then begin to merge actions that are currently only different because we didn't have a unqualified notion of the name in the parser. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85851 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-25change Sema::ActOnFriendTypeDecl to use GetTypeForDeclarator instead Chris Lattner
of ConvertDeclSpecToType, which I'd like to keep private to SemaType.cpp. We do this by cons'ing up a trivial Declarator for the type. John, please review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85060 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-25Audit the code for places where it is assumed that every base specifier ↵Sebastian Redl
refers to a RecordType. Add assertions or conditions as appropriate. This fixes another crash in the Apache stdlib vector. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85055 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-22When building types from declarators, instead of building two types (one forJohn McCall
the DeclaratorInfo, one for semantic analysis), just build a single type whose canonical type will reflect the semantic analysis (assuming the type is well-formed, of course). To make that work, make a few changes to the type system: * allow the nominal pointee type of a reference type to be a (possibly sugared) reference type. Also, preserve the original spelling of the reference type. Both of these can be ignored on canonical reference types. * Remove ObjCProtocolListType and preserve the associated source information on the various ObjC TypeLocs. Preserve the spelling of protocol lists except in the canonical form. * Preserve some level of source type structure on parameter types, but canonicalize on the canonical function type. This is still a WIP. Drops code size, makes strides towards accurate source location representation, slight (~1.7%) progression on Cocoa.h because of complexity drop. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84907 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-13Unify our diagnostic printing for errors of the form, "we didn't likeDouglas Gregor
what we found when we looked into <blah>", where <blah> is a DeclContext*. We can now format DeclContext*'s in nice ways, e.g., "namespace N", "the global namespace", "'class Foo'". This is part of PR3990, but we're not quite there yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84028 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-13Improve the internal representation and semantic analysis of friendDouglas Gregor
function templates. This commit ensures that friend function templates are constructed as FunctionTemplateDecls rather than partial FunctionDecls (as they previously were). It then implements template instantiation for friend function templates, injecting the friend function template only when no previous declaration exists at the time of instantiation. Oh, and make sure that explicit specialization declarations are not friends. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83970 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-11Test exception spec compatibility on return type and parameters.Sebastian Redl
Along the way, use RequireCompleteType when testing exception spec types. Separate all the ugly spec stuff into its own file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83764 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-10Implement the core checking for compatible exception specifications in ↵Sebastian Redl
assignment and initialization. The exception specification of the assignee must be the same or a subset of the target. In addition, exception specifications on arguments and return types must be equivalent, but this is not implemented yet. This currently produces two diagnostics for every invalid assignment/initialization, due to the diagnostic produced outside PerformImplicitConversion, e.g. in CheckSingleInitializer. I don't know how to suppress this; in any case I think it is the wrong place for a diagnostic, since there are other diagnostics produced inside the function. So I'm leaving it as it is for the moment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83710 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-09Refactor the LookupResult API to simplify most common operations. Require ↵John McCall
users to pass a LookupResult reference to lookup routines. Call out uses which assume a single result. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83674 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-07Refactoring around friend class templates. Better error message for friend ↵John McCall
enums. Don't create a new declaration for friend classes if a declaration already exists. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83505 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-06Refactor the code that walks a C++ inheritance hierarchy, searchingDouglas Gregor
for bases, members, overridden virtual methods, etc. The operations isDerivedFrom and lookupInBases are now provided by CXXRecordDecl, rather than by Sema, so that CodeGen and other clients can use them directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83396 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-29Desugaring optimizations. Add single-step desugaring methods to allJohn McCall
concrete types. Use unqualified desugaring for getAs<> and sundry. Fix a few users to either not desugar or use qualified desugar, as seemed appropriate. Removed Type's qualified desugar method, as it was easy to accidentally use instead of QualType's. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83116 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-26Rework the Parse-Sema interaction for friends to better support friendDouglas Gregor
class templates. We now treat friend class templates much more like normal class templates, except that they still get special name lookup rules. Fixes PR5057 and eliminates a bunch of spurious diagnostics in <iostream>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82848 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-24Refactor the representation of qualifiers to bring ExtQualType out of theJohn McCall
Type hierarchy. Demote 'volatile' to extended-qualifier status. Audit our use of qualifiers and fix a few places that weren't dealing with qualifiers quite right; many more remain. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82705 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-23This patch addresses a few issues related to 8.5.3 [dcl.init.ref]Fariborz Jahanian
It uses a recent API to find inherited conversion functions to do the initializer to reference lvalue conversion (and removes a FIXME). It issues the ambiguity diagnostics when multiple conversions are found. WIP. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82649 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-21Change all the Type::getAsFoo() methods to specializations of Type::getAs().John McCall
Several of the existing methods were identical to their respective specializations, and so have been removed entirely. Several more 'leaf' optimizations were introduced. The getAsFoo() methods which imposed extra conditions, like getAsObjCInterfacePointerType(), have been left in place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82501 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-15When implicitly declaring operators new, new[], delete, and delete[],Douglas Gregor
give them the appropriate exception specifications. This, unfortunately, requires us to maintain and/or implicitly generate handles to namespace "std" and the class "std::bad_alloc". However, every other approach I've come up with was more hackish, and this standard requirement itself is quite the hack. Fixes PR4829. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81939 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-11Cleanup and test C++ default arguments. Improvements include:Douglas Gregor
- Diagnose attempts to add default arguments to templates (or member functions of templates) after the initial declaration (DR217). - Improve diagnostics when a default argument is redefined.
