2009-11-18Incremental progress on using declarations. Split UnresolvedUsingDecl intoJohn McCall
two classes, one for typenames and one for values; this seems to have some support from Doug if not necessarily from the extremely-vague-on-this-point standard. Track the location of the 'typename' keyword in a using-typename decl. Make a new lookup result for unresolved values and deal with it in most places. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89184 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-17Carry lookup configuration throughout lookup on the LookupResult. GiveJohn McCall
LookupResult RAII powers to diagnose ambiguity in the results. Other diagnostics (e.g. access control and deprecation) will be moved to automatically trigger during lookup as part of this same mechanism. This abstraction makes it much easier to encapsulate aliasing declarations (e.g. using declarations) inside the lookup system: eventually, lookup will just produce the aliases in the LookupResult, and the standard access methods will naturally strip the aliases off. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89027 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-16First part of changes to eliminate problems with cv-qualifiers andDouglas Gregor
sugared types. The basic problem is that our qualifier accessors (getQualifiers, getCVRQualifiers, isConstQualified, etc.) only look at the current QualType and not at any qualifiers that come from sugared types, meaning that we won't see these qualifiers through, e.g., typedefs: typedef const int CInt; typedef CInt Self; Self.isConstQualified() currently returns false! Various bugs (e.g., PR5383) have cropped up all over the front end due to such problems. I'm addressing this problem by splitting each qualifier accessor into two versions: - the "local" version only returns qualifiers on this particular QualType instance - the "normal" version that will eventually combine qualifiers from this QualType instance with the qualifiers on the canonical type to produce the full set of qualifiers. This commit adds the local versions and switches a few callers from the "normal" version (e.g., isConstQualified) over to the "local" version (e.g., isLocalConstQualified) when that is the right thing to do, e.g., because we're printing or serializing the qualifiers. Also, switch a bunch of Context.getCanonicalType(T1).getUnqualifiedType() == Context.getCanonicalType(T2).getQualifiedType() expressions over to Context.hasSameUnqualifiedType(T1, T2) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88969 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-14- Have TryStaticImplicitCast set the cast kind to NoOp when binding a ↵Sebastian Redl
reference. CheckReferenceInit already inserts implicit casts to the necessary types. This fixes an assertion in CodeGen for some casts and brings a fix for PR5453 close, if I understand that bug correctly. - Also, perform calculated implicit cast sequences if they're determined to work. This finally diagnoses static_cast to ambiguous or implicit bases and fixes two long-standing fixmes in the test case. For the C-style cast, this requires propagating the access check suppression pretty deep into other functions. - Pass the expressions for TryStaticCast and TryStaticImplicitCast by reference. This should lead to a better AST being emitted for such casts, and also fixes a memory leak, because CheckReferenceInit and PerformImplicitConversion wrap the node passed to them. These wrappers were previously lost. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88809 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-14When type-checking a static cast (or the static_cast part of a C-styleDouglas Gregor
cast) that is converting to a class type, enumerate its constructors as in any other direct initialization. This ensures that we get the proper conversion sequence. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88751 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-14If we attempt to add a constructor template specialization that looksDouglas Gregor
like a copy constructor to the overload set, just ignore it. This ensures that we don't try to use such a constructor as a copy constructor *without* triggering diagnostics at the point of declaration. Note that we *do* diagnose such copy constructors when explicitly written by the user (e.g., as an explicit specialization). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88733 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-13When transforming an expression statement (e.g., for templateDouglas Gregor

2009-11-10Improve parsing of template arguments to lay the foundation forDouglas Gregor
handling template template parameters properly. This refactoring: - Parses template template arguments as id-expressions, representing the result of the parse as a template name (Action::TemplateTy) rather than as an expression (lame!). - Represents all parsed template arguments via a new parser-specific type, ParsedTemplateArgument, which stores the kind of template argument (type, non-type, template) along with all of the source information about the template argument. This replaces an ad hoc set of 3 vectors (one for a void*, which was either a type or an expression; one for a bit telling whether the first was a type or an expression; and one for a single source location pointing at the template argument). - Moves TemplateIdAnnotation into the new Parse/Template.h. It never belonged in the Basic library anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86708 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-09Unify the codepaths used to verify base and member initializers for explicitlyEli Friedman
and implicitly defined constructors. This has a number of benefits: 1. Less code. 2. Explicit and implicit constructors get the same diagnostics. 3. The AST explicitly contains constructor calls from implicit default constructors. This allows handing some cases that previously weren't handled correctly in IRGen without any additional code. Specifically, implicit default constructors containing calls to constructors with default arguments are now handled correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86500 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-07Make sure isCopyAssignment is only true for actual copy assignment operators,Eli Friedman
instead of all assignment operators. The mistake messes up IRGen because it ends up assuming that the assignment operator is actually the implicit copy assignment operator, and therefore tries to emit the RHS as an lvalue. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86307 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-05Fixed two places where we needed to force completion of a typeDouglas Gregor
(without complaining if it fails) to get proper semantics: reference binding with a derived-to-base conversion and the enumeration of constructors for user-defined conversions.

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

2009-10-22When 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
