2009-11-17Store "sugared" decls in LookupResults (i.e. decl aliases like using ↵John McCall
declarations); strip the sugar off in getFoundDecl() and getAsSingleDecl(), but leave it on for clients like overload resolution who want to use the iterators. Refactor a few pieces of overload resolution to strip off using declarations in a single place. Don't do anything useful with the extra context knowledge yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89061 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

2009-11-17When querying type qualifiers on QualType via one of the "non-local"Douglas Gregor
interfaces (which are used throughout the front end), combine the qualifiers on the QualType instance with the qualifiers on the canonical type to produce the set of qualifiers that, semantically, apply to that type. This should design away a large category of "qualifier-hidden-behind-a-typedef" buts like we saw in PR5383. Performance-wise, this caused a regression of ~0.5% on Cocoa.h, but it's totally worth it. We may actually be able to get a little more performance back by using CanQualType more often. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89018 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
