2008-07-25Remove call to isSEL and isSEL itself since the call is dead ↵Ted Kremenek
(isObjCObjectPointerType() will never return true for selectors). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54034 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-24Use ASTContext::isObjCObjectPointerType() to check if an ivar is a reference ↵Ted Kremenek
to an Objective-C object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53999 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-18Renamed deterministic EvalBinOp to DetermEvalBinOpNN. This name mangling is ↵Ted Kremenek
unfortunately needed because virtual methods with the same name can be hidden by subclasses. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53751 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-18Created ValueStateSet class to manage the creation of multiple states by a ↵Ted Kremenek
method. Modified the new EvalBinOpNN to generate states instead of nodes. This is a much simpler interface and is what clients will want to do. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53750 91177308-0d34-0410-b5e6-96231b3b80d8

there as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53743 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-17Begin major changes to EvalXXX methods in GRTransferFuncs. Currently some ↵Ted Kremenek
of the methods only return an RVal; we want them to be able to create an arbitrary number of states. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53739 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-17Moved RemoveDeadBindings logic for the contents of 'Store' to a virtual ↵Ted Kremenek
RemoveDeadBindings method in StoreManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53726 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-16Fix regression introduced by ↵Ted Kremenek
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20080714/006514.html. The regression was the casts from integers to pointers where not being handled: they would just return UnknownVal. This would greatly decrease path-sensitivity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53659 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-15Fix transfer function logic in GRSimpleVals for integer casts: only support ↵Ted Kremenek
casts from integers to integers. This fixes a crash reported by Anders Carlsson! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53649 91177308-0d34-0410-b5e6-96231b3b80d8

appears in the suffix of a function's name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53621 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-14Refactor Dead Stores error reporting to use the simplified ↵Ted Kremenek
BugReporter::EmitBasicReport interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53573 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-14Added method "EmitBasicReport" to BugReporter to simplify the emission of ↵Ted Kremenek
simple bug diagnostics. Refactored error reporting in CheckObjCDealloc and CheckObjCInstMethSignature to use this new bug reporting interface (major code simplification). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53560 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-11Add new check: -check-objc-methodsigs. This check scans methods inTed Kremenek
ObjCImplementationDecls and sees if a ancestor class defines a method with the same selector but with a different type signature. Right now it just compares return types, and mainly looks at differences in primitive values. The checking will be expanded in the future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53482 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-11Refactored auditor interface within GRExprEngine and GRCoreEngine to use a ↵Ted Kremenek
"batch auditor" to dispatch to specialized auditors instead of having a separate vector for each audited Expr*. This not only provides a much cleaner implementation, but also allows us to install auditors for any expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53464 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-10Refactored most of the "Store" piece of ValueState into a Store type. TheTed Kremenek
current store implementation is now encapsulated by BasicStore. These changes prompted some long due constification of ValueState. Much of the diffs in this patch include adding "const" qualifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53423 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-08Initial work on splitting the ValueState into an Environment, Store, andTed Kremenek
Constraints. These concepts are already present in the current ValueState, but the implementation is monolothic. Making ValueState more modular opens up new design choices for customizing the analysis engine. In the context of the analysis engine, the "Environment" is the binding between Expr* (expressions) and intermediate symbolic values (RValues). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53252 91177308-0d34-0410-b5e6-96231b3b80d8
