Ted Kremenek 707ece6025 Do not register ObjCInterfaceDecls implicitly created by @class in the
current DeclContext.  These "imaginary" declarations pose issues for
clients searching DeclContext for actual declarations.  Instead,
register them for name lookup, and add the ObjCInterfaceDecl later to
the DeclContext when we hit an actual @interface declaration.

This also fixes a bug where the invariant that the Decls in a
DeclContext are sorted in order of their appearance is no longer
violated.  What could happen is that an @class causes an
ObjCInterfaceDecl to get added first to the DeclContext, then the
ObjCClassDecl itself is added, and then later the SourceLocation of
the ObjCInterfaceDecl is updated with the correct location (which is
later in the file).  This breaks an assumed invariant in
ResolveLocation.cpp (and possibly other clients).

John McCall 27b18f8144 Carry lookup configuration throughout lookup on the LookupResult. Give
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.

2009-11-17 01:22:05 +00:00
Douglas Gregor 6c254bf522 When querying type qualifiers on QualType via one of the "non-local"
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.

Douglas Gregor 1b8fe5b716 First part of changes to eliminate problems with cv-qualifiers and
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)

Sebastian Redl 7c353685bc - Have TryStaticImplicitCast set the cast kind to NoOp when binding a 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.

   o Frontend diagnostics are now caught (for example, errors in command line arguments), although there isn't yet a way to specify that they are expected. That would be nice though.
