Improve diagnostics in ReturnStackAddressChecker for returning a stack-allocated block.  Implements the rest of <rdar://problem/7387385>.

instead of checking explicitly for an EnumConstantDecl.  This folds references
to constant integer VarDecls, which has two benefits:

1. Slightly smaller emitted code from emitting a constant instead of a load,
and skipping emitting some constant globals.
2. Some code forgets to define static constant member variables; emitting a
load instead of the value in that case leads to a link error. (Such programs
are technically not well-formed, but in practice build with g++.)

internal linkage.  Fixes PR5433.

the set of variables "captured" by a block.  Until the analysis gets
more sophisticated, for now we stop the retain count tracking of any
objects (transitively) referenced by these variables.

llvm-svn: 89929

Teach RegionStoreManager::RemoveDeadBindings() about BlockDataRegions.  Any VarRegion for a "captured" variable should also be considered live.

llvm-svn: 89928

Add iterators to BlockDataRegion that allow clients to iterate over the VarRegions for "captured" variables for a block.

llvm-svn: 89927

Added batch versions of GRState::scanReachableSymbols() so that clients can scan a collection of SVals or MemRegions all at once.

llvm-svn: 89926

Add a ThunkAdjustment struct which holds a non-virtual and a virtual adjustment offset. Start using it. General cleanup in Mangle.cpp.

llvm-svn: 89925

Enhance LiveVariables to understand that blocks can extend the liveness of a variable by "capturing" them in a BlockExpr.

This required two changes:

1) Added 'getReferencedgetReferencedBlockVars()' to AnalysisContext so
that clients can iterate over the "captured" variables in a block.

2) Modified LiveVariables to take an AnalysisContext& in its
constructor and to call getReferencedgetReferencedBlockVars() when it
processes a BlockExpr*.

Factor out a LangStandard class and coalesce the information about the standards into LangStandards.def
 - I'd appreciate another pair of eyeballs to double check this.

maintains a stack of evaluation contexts rather than having the parser
do it. This change made it simpler to track in which contexts
temporaries were created, so that we could...

"Forget" about temporaries created within unevaluated contexts, so
that we don't build a CXXExprWithTemporaries and, therefore, destroy
the integral-constness of our expressions. Fixes PR5609.

'BlockDataRegion' to distinguish between the code associated with a
block (which is represented by 'BlockTextRegion') and an instance of a
block, which includes both code and data.  'BlockDataRegion' has an
associated LocationContext, which can be used to eventually model the
lifetime of a block object once LocationContexts can represent scopes
(and iterations around a loop, etc.).

the linkage of a declaration. Switch the lame (and completely wrong)
NamedDecl::hasLinkage() over to using the new NamedDecl::getLinkage(),
along with the "can this declaration be a template argument?" check
that started all of this.

Fixes -fsyntax-only for PR5597.

llvm-svn: 89890

Add a new RetainReleaseChecker class (that subclasses CheckerVisitor) to extend the functionality of the retain/release checker using the new Checker interface.  Pieces of CFRefCount will gradually be migrated to this new class over time.

llvm-svn: 89889

llvm-svn: 89888

Call GRExprEngine::setTransferFunctions() after registering all Checkers.  This allows GRTransferFuncs::RegisterChecks() to always be called after all checkers have been registered.

llvm-svn: 89887

Consolidate logic in ActionInlineCall by having it call ActionGRExprEngine instead of replicating most of its logic (and missing pieces).

llvm-svn: 89886

initializer name is available.

llvm-svn: 89885

Make RegisterInternalChecks() part of GRExprEngine's private implementation by making it a static function within GRExprEngine.cpp.

llvm-svn: 89884

Register internal checks with GRExprEngine when it is constructed, not manually in AnalysisConsumer.cpp.

llvm-svn: 89883

only stop processing the checkers after all the nodes for a current
check have been processed.  This (I believe) handles the case where
PredSet (the input nodes) contains more than one node due to state
bifurcation.  Zhongxing: can you review this?
