2013-01-15Fix CastDavid Greene
Avoid a cast-away-const error by properly using const_cast<>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172558 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-19Change DeclContextLookup(Const)Result to (Mutable)ArrayRef<NamedDecl*>, as ↵David Blaikie
per review discussion in r170365 This does limit these typedefs to being sequences, but no current usage requires them to be contiguous (we could expand this to a more general iterator pair range concept at some point). Also, it'd be nice if SmallVector were constructible directly from an ArrayRef but this is a bit tricky since ArrayRef depends on SmallVectorBaseImpl for the inverse conversion. (& generalizing over all range-like things, while nice, would require some nontrivial SFINAE I haven't thought about yet) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170482 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-22Fix CXXRecordDecl::forallBases to not look through bases which are dependentRichard Smith
and defined within the current instantiation, but which are not part of the current instantiation. Previously, it would look at bases which could be specialized separately from the current template. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168477 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-10Rework my implementation of circular-reference finding to not useDouglas Gregor
CXXRecordDecl::forallBases, which does *not* do what I need. Fixes the failure introduced in r167651. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167668 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-10Diagnostic circular inheritance involving dependent base classes. WeDouglas Gregor
would have diagnosed this at instantiation time anyway, if only we didn't hang on all of these test cases. Fixes <rdar://problem/12629723> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167651 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-11Switch a SmallPtrSet/SmallVector pair over to SetVector.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163600 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-23Change a bunch of cases where we do "getAs<...>->doSomething()" toTed Kremenek
"castAs<...>->doSomething()". The analyzer was flagging these as potential null dereferences, which is technically true. The invariants appear to be that these casts should never fail, so let's use castAs<> instead and avoid a runtime check. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162468 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-21Use CanQualType to enforce the use of a canonical type argument toDouglas Gregor
CXXBasePaths::isAmbiguous(), rather than just asserting that we have a canonical type. Fixes PR7176. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104374 91177308-0d34-0410-b5e6-96231b3b80d8
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

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
