Douglas Gregor bab2b3c70f Refactor code-completion support for message sends, collecting the
code to find and add Objective-C methods (starting at an
ObjCContainerDecl) into a single, static function. Also, make sure
that we search into the implementations of classes and categories to
find even more methods.

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.

Eli Friedman b0bc559b19 PR5526: Make sure to set the right cast kinds for the inserted implicit casts.
llvm-svn: 89023
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)

Douglas Gregor 8f3952cda9 When performing a static downcast as part of a static_cast, make sure
that we're dealing with canonical types like the documentation say
(yay, CanQualType). Alas, this is another instance where using

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.

- This reimplements -verify as just another DiagnosticClient, which buffers the diagnostics and checks them when the source file is complete. There are some hacks to make this work, but they are all internal, and this exposes a better external interface.

 - This also tweaks a few things:
   o Errors are now just regular diagnostics.
   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.

 - Not yet used.

Douglas Gregor 19ac2d6494 When comparing template parameter lists, distinguish between three cases:
- Comparing template parameter lists to determine if we have a redeclaration
  - Comparing template parameter lists to determine if we have equivalent
    template template parameters
  - Comparing template parameter lists to determine whether a template 
    template argument is valid for a given template template parameter.

Previously, we did not distinguish between the last two cases, which
got us into trouble when we were looking for exact type matches
between the types of non-type template parameters that were dependent
types. Now we do, so we properly delay checking of template template
arguments until instantiation time.

Also, fix an accidental fall-through in a case statement that was
causing crashes.

Douglas Gregor adee3e3b22 Template argument deduction for template template parameters. This
permits, among other things, ripping apart and reconstructing
templates via partial specialization:

  template<typename T> 
  struct DeepRemoveConst { typedef T type; };

  template<typename T>
  struct DeepRemoveConst<const T> {
    typedef typename DeepRemoveConst<T>::type type;
  };

  template<template<typename> class TT, typename T>
  struct DeepRemoveConst<TT<T> > {
    typedef TT<typename DeepRemoveConst<T>::type> type;
  };

Also, fix a longstanding thinko in the code handling partial ordering
of class template partial specializations. We were performing the
second deduction without clearing out the results of the first
deduction. It's amazing we got through so much code with such a
horrendous error :(

Douglas Gregor 84d49a2085 Improve diagnostics when a default template argument does not match
with its corresponding template parameter. This can happen when we
performed some substitution into the default template argument and
what we had doesn't match any more, e.g.,

  template<int> struct A;
  template<typename T, template<T> class X = A> class B;

  B<long> b;

Previously, we'd emit a pretty but disembodied diagnostic showing how
the default argument didn't match the template parameter. The
diagnostic was good, but nothing tied it to the *use* of the default
argument in "B<long>". This commit fixes that.

Also, tweak the counting of active template instantiations to avoid
counting non-instantiation records, such as those we create for
(surprise!) checking default arguments, instantiating default
arguments, and performing substitutions as part of template argument
deduction.

Douglas Gregor eebed72fbb Move handling of template parameter packs out of the
template-type-parameter specific template argument checking code and
up to the template argument checking loop. In theory, this should make

for us to care anyway (YET!), so this is mostly a re-organization to
simplify CheckTemplateArgument.

Douglas Gregor e62e6a0191 Before checking a template template argument against its corresponding
template template parameter, substitute any prior template arguments
into the template template parameter. This, for example, allows us to
properly check the template template argument for a class such as:

  template<typename T, template<T Value> class X> struct Foo;

The actual implementation of this feature was trivial; most of the
change is dedicated to giving decent diagnostics when this
substitution goes horribly wrong. We now get a note like:

  note: while substituting prior template arguments into template
      template parameter 'X' [with T = float]

As part of this change, enabled some very pedantic checking when
comparing template template parameter lists, which shook out a bug in
our overly-eager checking of default arguments of template template
parameters. We now perform only minimal checking of such default
arguments when they are initially parsed.
