BumpPtrAllocator rather than using up slots in the ASTContext's
cache. Now that we do this, we don't have to worry about destroying
dependent diagnostics when destroying a DependentStoredDeclsMap.

cache of PartialDiagnostic::Storage objects into an allocator within
the ASTContext. This eliminates a significant amount of malloc
traffic, for a 10% performance improvement in -fsyntax-only wall-clock
time with 403.gcc's combine.c.

Also, eliminate the RequireNonAbstractType hack I put in earlier,
which was but a symptom of this larger problem.

Fixes <rdar://problem/7806091>.

When collecting virtual bases it's very important to use the canonical type of the base class. Otherwise, we might add the same virtual base class twice if the virtual base is an instantiated template. Fixes PR6251.

llvm-svn: 99829

Fix a nasty bug in the virtual base computation which would lead to us initializing virtual bases in the wrong order.

This patch moves some methods from QualType to Type and changes the users to
use -> instead of .

llvm-svn: 99805

What happens here is that we actually turn the first declaration into a
definition, regardless of whether it was actually originally a definition,
and furthermore we do this all after we've instantiated all the declarations.
This exposes a bug in my DefinitionData patch where it was only setting the
DefinitionData for previous declarations, not future declarations.
Fortunately, there's an iterator for that.

of a friend declaration is a specific specialization of a template.

I was surprised to find that this was required for an access-controlled selfhost.

function within a class hierarchy (C++ [class.virtual]p2).

We use the final-overrider computation to determine when a particular
class is ill-formed because it has multiple final overriders for a
given virtual function (e.g., because two virtual functions override
the same virtual function in the same virtual base class). Fixes
PR5973.

We also use the final-overrider computation to determine which virtual
member functions are pure when determining whether a class is
abstract or diagnosing the improper use of an abstract class. The
prior approach to determining whether there were any pure virtual
functions in a class didn't cope with virtual base class subobjects
properly, and could not easily be fixed to deal with the oddities of
subobject hiding. Fixes PR6631.

llvm-svn: 98594

SourceManager's getBuffer() (and similar) operations. This abstract
can be used to force callers to cope with errors in getBuffer(), such
as missing files and changed files. Fix a bunch of callers to use the
new interface.

Add some very basic checks for file consistency (file size,
modification time) into ContentCache::getBuffer(), although these
checks don't help much until we've updated the main callers (e.g.,
SourceManager::getSpelling()).

Destroy methods at the same time, to ensure that the correct teardown was
being done.

the ivar to the DeclContext (which we weren't doing before).

This allows us to simplify ASTContext::CollectNonClassIvars() by
removing ASTContext::CollectProtocolSynthesizedIvars().  Now all
ivars can be found by either inspecting the ObjCInterfaceDecl and
its companion ObjCImplementationDecl.

llvm-svn: 98280

I'm expecting this portion of the AST to grow and change, and I'd like to
be able to do that with minimal recompilation.  If this proves unnecessary
when access control is fully-implemented, I'll fold the classes back into
