Simplify 'Environment' to contain only one map from 'const Stmt*' to SVals, greatly simplifying the logic of the analyzer in many places.  We now only distinguish between block-level expressions and subexpressions in Environment::RemoveDeadBindings and GRState pretty-printing.

name, e.g.,
  
  x->Base::f()

retain the qualifier (and its source range information) in a new
subclass of MemberExpr called CXXQualifiedMemberExpr. Provide
construction, transformation, profiling, printing, etc., for this new
expression type.

When a virtual function is called via a qualified name, don't emit a
virtual call. Instead, call that function directly. Mike, could you
add a CodeGen test for this, too?

Fix regression in BasicStoreManager caused by implicitly casting loaded values and trying to load/store from arrays.  RegionStoreManager already properly handles these cases well; we just need to gracefully not handle this case in BasicStoreManager.  This fixes PR 4781.

when using the non-fragile Objective-C ABI.  This fixes <rdar://problem/7168531>.

llvm-svn: 80047

implicit cast logic in RegionStoreManager to BasicStoreManager. This involved
moving CastRetriedVal from RegionStoreManager to StoreManager.

Now AnalysisManager is the only place we can get CodeDecl.
This leads to an API change: GRState::bindExpr() now takes the CFG argument.

correctly reason about undefined or unknown values. This fixes PR 4759.

AnalysisContext should never change. Along the way, propagate some constness
around.

SelfRegion represented the object bound to 'self' (when analyzing Objective-C
methods) upon entry to a method. Having this region stored on the side ignores
the current stack frame that we might be analyzing (among other things), and is
a problem for interprocedural analysis.

For RegionStoreManager, the value for SelfRegion is just lazily created.

For BasicStoreManager, the value for SelfRegion is bound eagerly to 'self', but
no explicit tracking of SelfRegion on the side is made.

As part of this change, remove the restriction in BasicStoreManager that we only
track ivars for 'self'. This shouldn't actually change anything in terms of
precision, and simplifies the logic.

just as if it behaved like an init function.  This fixes <rdar://problem/7129086>.

Although this does not make the CFG more correct, it makes the CFG more 
beautiful without multiple roots.

llvm-svn: 79509

Otherwise we get a wrong CFG.

fixing <rdar://problem/7152619>. Along the way, merge test cases in
'test/Analysis/rdar-6539791.c' into 'test/Analysis/retain-release.m'.

and other core analysis logic will be untied to a particular Decl.

Removed an unnecessary loop to get to setters incoming

to do in this area (WIP).

BugReporterVisitor objects. This allows various checks to include diagnostics
such as 'assuming value is null' with little extra work. Eventually this API
should be refactored to be cleaner and more simple.
