dependent declaration reference, since we might not be in a dependent
context. Fixes a fiendish crash-on-invalid in Boost.FunctionTypes that
I wasn't able to reduce to anything useful.

template argument deduction, use the lexical declaration context as
the owner for friend function templates. Fixes 2 failures in
Boost.Graph.
llvm-svn: 102489
keep track of whether we need to zero-initialize storage prior to
calling its constructor. Previously, we were only tracking this when
implicitly constructing the object (a CXXConstructExpr).
Fixes Boost's value-initialization tests, which means that the
Boost.Config library now passes all of its tests.
llvm-svn: 102461
we were relying on checking for abstract class types when an array
type was actually used to declare a variable, parameter, etc. However,
we need to check when the construct the array for, e.g., SFINAE
purposes (see DR337). Fixes problems with Boost's is_abstract type
trait.

UnresolvedLookupExpr and UnresolvedMemberExpr by substituting the
naming class we computed when building the expression in the
template...
... which we didn't always do correctly. Teach
UnresolvedMemberExpr::getNamingClass() all about the new
representation of injected-class-names in templates, so that it can
return a naming class that is the current instantiation.
Also, when decomposing a template-id into its template name and its
arguments, be sure to set the naming class on the LookupResult
structure.
Fixes PR6947 the right way.

of a class template or class template partial specialization. That is to
say, in
template <class T> class A { ... };
or
template <class T> class B<const T*> { ... };
make 'A<T>' and 'B<const T*>' sugar for the corresponding InjectedClassNameType
when written inside the appropriate context. This allows us to track the
current instantiation appropriately even inside AST routines. It also allows
us to compute a DeclContext for a type much more efficiently, at some extra
cost every time we write a template specialization (which can be optimized,
but I've left it simple in this patch).
llvm-svn: 102407
by using TypeSourceInfo, cleaning up the representation
somewhat. Teach getTypeOperand() to strip references and
cv-qualifiers, providing the semantic view of the type without
requiring any extra storage (the unmodified type remains within the
TypeSourceInfo). This fixes a bug found by Boost's call_traits test.
Finally, clean up semantic analysis, by splitting the ActOnCXXTypeid
routine into ActOnCXXTypeId (the parser action) and two BuildCXXTypeId
functions, which perform the semantic analysis for typeid(type) and
typeid(expression), respectively. We now perform less work at template
instantiation time (we don't look for std::type_info again) and can
give better diagnostics.

isStructureOrClassType() as needed (which is alsmost
everywhere). Fixes the remaining failure in Boost.Utility/Swap.

references and isa expressions. Also, test template instantiation of
unresolved member references to Objective-C ivar references and isa
expressions.
llvm-svn: 102374
function-parameter checking and splitting it into the normal
ActOn*/Build* pair in Sema. We now use VarDecl to represent the @catch
parameter rather than the ill-fitting ParmVarDecl.
llvm-svn: 102347
using declaration, look at its underlying declaration to determine the
lookup result kind (e.g., overloaded, unresolved). Fixes at least one
issue in Boost.Bimap.

whose argument is then a copy constructor call...
Found by Boost.Regex which, alas, still isn't building.
llvm-svn: 102269
when they are not complete (since we could not match them up to
anything) and ensuring that enum parsing can cope with dependent
elaborated-type-specifiers. Fixes PR6915 and PR6649.

one that is known to refer to a type. Patch from Enea Zaffanella!
llvm-svn: 102243

(which is a bit of a hack), call a new ActOnObjCExceptionDecl
action. We'll be moving more functionality into this handler to
perform earlier checking of @catch.
