2010-03-23Implement computation of the final overriders for each virtualDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99351 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-03Implement name hiding for names found through virtual base subobjectsDouglas Gregor
that are hidden by other derived base subobjects reached along a lookup path that does *not* pass through the hiding subobject (C++ [class.member.lookup]p6). Fixes PR6462. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97640 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-03Refactor CXXRecordDecl::lookupInBases() to push the recursion down aDouglas Gregor
level. No functionality change, and it obeys access control this time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97634 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-03Factor out the recursive lookup into C++ base classes into a separate,Douglas Gregor
static function. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97618 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-11Eliminate the ASTContext parameter from RecordDecl::getDefinition()Douglas Gregor
and CXXRecordDecl::getDefinition(); it's totally unnecessary. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95836 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-09Reset the found-virtual-base state unless the *current* base produces a path,John McCall
not *any* base up to now has produced a path. Fixes PR 6254. I'll do the access-control part of this patch RSN. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95638 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-20First pass at collecting access-specifier information along inheritance paths.John McCall
Triggers lots of assertions about missing access information; fix them. Will actually consume this information soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94038 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-09In CXXRecordDecl::forallBases, add the base to the "queue", so we walk more ↵Anders Carlsson

2009-11-16First part of changes to eliminate problems with cv-qualifiers andDouglas Gregor
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) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88969 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-06Refactor the code that walks a C++ inheritance hierarchy, searchingDouglas Gregor
for bases, members, overridden virtual methods, etc. The operations isDerivedFrom and lookupInBases are now provided by CXXRecordDecl, rather than by Sema, so that CodeGen and other clients can use them directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83396 91177308-0d34-0410-b5e6-96231b3b80d8
