Douglas Gregor f7d7771812 Fix the recently-added warning about 'typename' and 'template'
disambiguation keywords outside of templates in C++98/03. Previously,
the warning would fire when the associated nested-name-specifier was
not dependent, but that was a misreading of the C++98/03 standard:
now, we complain only when we're outside of any template.

Douglas Gregor 1c69bf00ae If a non-dependent base class initializer fails to match any direct or
virtual base class, but the class still has dependent base classes,
then don't diagnose the failed match as an error: the right base class
might magically appear. Fixes PR7259.

2010-06-16 09:33:39 +00:00
John McCall e9cccd86da Fix a point of semantics with using declaration hiding: method templates
introduced by using decls are hidden even if their template parameter lists
or return types differ from the "overriding" declaration.

Propagate using shadow declarations around more effectively when looking up
template-ids.  Reperform lookup for template-ids in member expressions so that
access control is properly set up.

Fix some number of latent bugs involving template-ids with totally invalid
base types.  You can only actually get these with a scope specifier, since
otherwise the template-id won't parse as a template-id.

Fixes PR7384.

Douglas Gregor 6972a62c8f Give Type::isIntegralType() an ASTContext parameter, so that it
provides C "integer type" semantics in C and C++ "integral type"
semantics in C++. 

Note that I still need to update isIntegerType (and possibly other
predicates) using the same approach I've taken for
isIntegralType(). The two should have the same meaning, but currently
don't (!).

Douglas Gregor b90df60b3b Introduce Type::isIntegralOrEnumerationType(), to cover those places
in C++ that involve both integral and enumeration types. Convert all
of the callers to Type::isIntegralType() that are meant to work with
both integral and enumeration types over to
Type::isIntegralOrEnumerationType(), to prepare to eliminate
enumeration types as integral types.

Jeffrey Yasskin 5d474d0a96 Fix the 64-bit build. operator<<(DiagnosticBuilder, long) doesn't exist, so

John McCall c392f37ae8 Split DependentNameType into two types. DependentNameType represents the
case of an elaborated-type-specifier like 'typename A<T>::foo', and
DependentTemplateSpecializationType represents the case of an
elaborated-type-specifier like 'typename A<T>::template B<T>'.  The TypeLoc
representation of a DependentTST conveniently exactly matches that of an
ElaboratedType wrapping a TST.

Kill off the explicit rebuild methods for RebuildInCurrentInstantiation;
the standard implementations work fine because the nested name specifier
is computable in the newly-entered context.

Tom Care b704270779 Added FixIt support to printf format string checking.
- Refactored LengthModifier to be a class.
- Added toString methods in all member classes of FormatSpecifier.
- FixIt suggestions keep user specified flags unless incorrect.

Limitations:
- The suggestions are not conversion specifier sensitive. For example, if we have a 'pad with zeroes' flag, and the correction is a string conversion specifier, we do not remove the flag. Clang will warn us on the next compilation.

Douglas Gregor 1fc3d66da4 Tweak our handling of the notion of a standard conversion sequence
being a subsequence of another standard conversion sequence. Instead
of requiring exact type equality for the second conversion step,
require type *similarity*, which is type equality with cv-qualifiers
removed at all levels. This appears to match the behavior of EDG and
VC++ (albeit not GCC), and feels more intuitive. Big thanks to John
for the line of reasoning that supports this change: since
cv-qualifiers are orthogonal to the second conversion step, we should
ignore them in the type comparison.
