variable initializer and the other expressions in an IfStmt.
This change required adding a 'DoDestroy()' method for IfStmt that did
not include destroying the initializer (since that is owned by the
VarDecl).

that this is true when mangling, then fix up the various places in
Sema and/or CodeGen that need to remove qualifiers. Addresses a

member function thereof), perform the template instantiation each time
the default argument is needed. This ensures that
(1) We get different CXXTemporary objects for each instantiation, and
(2) Any other instantiations or definitions triggered by the
instantiation of the default argument expression are guaranteed to
happen; previously, they might have been suppressed, e.g., because
they happened in an unevaluated context.
This fixes the majority of PR5810. However, it does not address the
problem where we may have multiple uses of the same CXXTemporary
within an expression when the temporary came from a non-instantiated
default argument expression.

As the FIXME indicates, RewriteByRefVar() won't work for multiple declarators (in general). I've discussed this with Fariborz and he is aware of the limitation.

Currently the builtin still accepts the full range for compatibility.

this is a losing strategy. For now this is unambiguous more friendly, though.

a size, check whether the transformed type is itself an array type. If
so, take the major array bound as the size to allocate. Fixes PR5833.

InitializationSequence (when a FunctionDecl is present). This required
a few small fixes to initialization sequences:
- Make sure to use the adjusted parameter type for initialization of
function parameters.
- Implement transparent union calling semantics in C
llvm-svn: 91902
With this seemingly insignificant fix, we are now able to build and link clang using clang itself! (LLVM still has to be built with gcc for the time being).
llvm-svn: 91893
this was useful, and on review Doug and I decided it was probably on the level
of a bug in the standard and therefore not worth a warning even in -pedantic.
If someone disagrees and urgently wants clang++ to warn about this in strict
c++98 mode, we can talk about it.

constructor call, the conversion is only a standard conversion
sequence if that constructor is a copy constructor. This fixes PR5834
in a semi-lame way, because the "real" fix will be to move over to
InitializationSequence. That will happen "soonish", but not now.

- Correctly is in quotes, because we are following what I interpreted as GCC's
intent (which diverges from practice, naturally).
- Also, fix the arch define for arm1136jf-s.
llvm-svn: 91855
explicitly-specified template arguments are enough to determine the
instantiation, and either template argument deduction fails or is not
performed in that context, we can resolve the template-id down to a
function template specialization (so sayeth C++0x
[temp.arg.explicit]p3). Fixes PR5811.
llvm-svn: 91852
not deduce an "overload" type. Such a deduction indicates a failure in
semantic analysis (e.g., PR5811) that currently isn't caught until
code-generation time. This assertions makes it clearer that this
particular issue is a semantic-analysis problem, not a code-gen problem.

recursing in CGDebugInfo::CreateTypeNode, teach
CanonicalizeTypeForDebugInfo---now called UnwrapTypeForDebugInfo---to

ElaboratedType, QualifiedNameType, and SubstTemplateTypeParmType type

and "typeof" nodes, rather than asserting nondescriptly.

Sema::getTypeName.
"LookupNestedNameSpecifierName" isn't quite the right kind of lookup, though;
it doesn't ignore namespaces. Someone more familiar with the lookup code
should fix this properly.
llvm-svn: 91809
Because of the rules of base-class lookup* and the restrictions on typedefs, it
was actually impossible for this to cause any problems more serious than the
spurious acceptance of
template <class T> class A : B<A> { ... };
instead of
template <class T> class A : B<A<T> > { ... };
but I'm sure we can all agree that that is a very important restriction which
is well worth making another Parser->Sema call for.
(*) n.b. clang++ does not implement these rules correctly; we are not ignoring
non-type names
llvm-svn: 91792
Clang reasonably adds all the base specifiers in one pass; this is now required
for correctness to prevent lookup from going mad. But this has the advantage of
establishing the correct context when looking up base specifiers, which will be
important for access control.

small bug fixes in SemaInit, switch over SemaDecl to use it more often, and

- In particular, it can claim features for itself instead of always passing them on to LLVM.
- This allows using the target features as a generic mechanism for passing target specific options to the TargetInfo instance, which may need them for initializing preprocessor defines, etc.

InitializationSequence. Specially, switch initialization of a C++
class type (either copy- or direct-initialization).
Also, make sure that we create an elidable copy-construction when
performing copy initialization of a C++ class variable. Fixes PR5826.
llvm-svn: 91750
Avoids an assertion arising during object-argument initialization in overload
resolution. In theory we can resolve this at definition time if the class
hierarchy for the member is fully known.

I accidentally checked in the test case for this in the last commit ---
fortunately, that refactor was inspired by having debugged this problem already,
so I can fix the bug quick (though probably not fast enough for the buildbots).

different functions and pick the function at lookup initialization time.
In theory we could actually divide the criteria functions into N different
functions for the N cases, but it's so not worth it.
Among other things, lets us invoke LookupQualifiedName without recomputing
IDNS info every time.
Do some refactoring in SemaDecl to avoid an awkward special case in LQN
that was only necessary for redeclaration testing for anonymous structs/unions ---
which could be done more efficiently with a scoped lookup anyway.
llvm-svn: 91676
new InitializationSequence. This fixes some bugs (e.g., PR5808),
changed some diagnostics, and caused more churn than expected. What's
new:
- InitializationSequence now has a "C conversion sequence" category
and step kind, which falls back to
- Changed the diagnostics for returns to always have the result type
of the function first and the type of the expression second.
CheckSingleAssignmentConstraints to peform checking in C.
- Improved ASTs for initialization of return values. The ASTs now
capture all of the temporaries we need to create, but
intentionally do not bind the tempoary that is actually returned,
so that it won't get destroyed twice.
- Make sure to perform an (elidable!) copy of the class object that
is returned from a class.
- Fix copy elision in CodeGen to properly see through the
subexpressions that occur with elidable copies.
- Give "new" its own entity kind; as with return values and thrown
objects, we don't bind the expression so we don't call a
destructor for it.
Note that, with this patch, I've broken returning move-only types in
C++0x. We'll fix it later, when we tackle NRVO.
