Ted Kremenek 4413714946 Reverted part of r59335: http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20081110/009243.html ...

In that patch I added a bogus type promotion for unary '!'.

The real bug was more fallout from edges cases with compound assignments and conjured symbolic values.  Now the conjured value has the type of the LHS expression, and we do a promotion to the computation type.  We also now correctly do a conversion from the computation type back to the LHS type.

BasicConstraintManager.cpp

Print integer value instead of raw pointer. This is a hack to be fixed by migrating the output in analyzer to llvm::raw_ostream.

2008-11-10 05:00:06 +00:00

BasicObjCFoundationChecks.cpp

Added method "getSelfRegion" to Store. This method returns the region associated with the "this" or "self" object (C++ and Objective-C respectively).

BasicObjCFoundationChecks.h

Change implementation of NSError** coding-style check to be invoked at the end of the retain/release analysis.

BasicStore.cpp

StoreManager::BindDecl now takes an SVal* for the initialization value instead of an Expr* (which can be null). Lazy symbolication of conjured symbols is now the sole responsibility of GRExprEngine.

2008-11-12 19:18:35 +00:00

BasicValueFactory.cpp

CompoundVal now uses an ImmutableList<SVal> to store its set of SVals. This change was motivated by the need to allow state-splitting in GRExprEngine::VisitInitListExpr. As a side-benefit, we no longer need to perform any copies of SVals when creating a CompoundSVal, and the profiling of CompoundSVal is now constant time.

BugReporter.cpp

This patch did the following renaming. There should be no functional changes.

CFRefCount.cpp

GRExprEngine/CFRefCount/GRSimpleVals: We don't do any special handling (yet) of vector types. Add explicit checks that when we process integers that they really are scalars.

CheckDeadStores.cpp

Enhance dead store checker to not flag preincrements to dead variables where the preincrement is a subexpression, e.g. foo(++x); This can cause false negatives, but will remove a whole class of false positives.

CheckNSError.cpp

- constify some uses of MemRegion* (MemRegion should be immutable).

CheckObjCDealloc.cpp

Add a new expression class, ObjCSuperExpr, to handle the Objective-C 'super'. Remove ObjCThis from PredefinedExpr

CheckObjCInstMethSignature.cpp

Added method "EmitBasicReport" to BugReporter to simplify the emission of simple bug diagnostics.

CheckObjCUnusedIVars.cpp

The "unused ivar" check now has a category: "Optimization"

Enhance return-of-stack-address checker to recognize regions created by alloca().

GRSimpleVals.cpp

Implement FIXME in GRExprEngine::VisitUnaryOperator() to handle implicit conversions caused by the '!' operator. This required adding some logic to GRSimpleVals to reason about nonloc::LocAsInteger SVals. This code appears to work fine, but it should eventually be cleaned up.
