2008-08-29Migrate the rest symbolic analysis stuff to BasicConstraintManager.Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55536 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-29Added "getBindings" and "BindingAsString" to GRStateManager and StoreManager.Ted Kremenek
Migrated CFRefCount.cpp to use getBindings and BindingsAsString instead of making assumptions about the Store (removed dependence on GRState::vb_iterator). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55522 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28Remove BasicStore.h (migrated function prototype for CreateBasicStore() to ↵Ted Kremenek
Store.h) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55519 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28Remove Regions.h and Regions.cpp, since we are now using an even more ↵Ted Kremenek
abstract representation of "memory regions" in the static analyzer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55515 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28Make store "Regions" and "Bindings" more abstract instead of concrete variants.Ted Kremenek
Their precise semantics will be implemented by a specific StoreManager. Use function pointer to create the StoreManager in GRStateManager. This matches how we create ConstraintsManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55514 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55494 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28Fixed analyzer caching bug in DeclStmt.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55487 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-27Make the destructor of ConstraintManager virtual.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55448 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-27Added "Auditor" interface for auditing the construction of ExplodedGraphs.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55403 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-27Make implementation of ExplodedNodeImpl::addPredecessor out-of-line.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55402 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-26Remove default value for 'Pred' argument to GRCoreEngineImpl::GenerateNode().Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55392 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-25Added 'extents' for Regions.Ted Kremenek
Added 'getExtent()' to StoreManager. Implemented 'getExtent()' for BasicStoreManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55321 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Simplify interface to Store::AddDeclTed Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55213 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Added Regions.h: Regions define abstract memory locations for the static ↵Ted Kremenek
analyzer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55211 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-21Move the handling of DeclStmt from GRExprEngine to BasicStoreManager.Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55144 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-20Patch by Zhongxing Xu:Ted Kremenek
This patch moves some code in GRStateManager::RemoveDeadBindings() to EnvironmentManager::RemoveDeadBindings(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55064 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-19Move store pretty-printing logic inside of StoreManager (previously in GRState).Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55013 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-19Patch by Zhongxing Xu!Ted Kremenek
This patch extends BasicStoreManager::getInitialStore() to include code that symbolicates input variables. It also removes redundant handling of ImplicitParamDecl, since it is a subclass of VarDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54993 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-17Migrate the retain/release checker to not manage the RefBindings::Factory objectTed Kremenek
directly, but instead have GRStateManager manage it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54862 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-17Migrate GRState::ConstEqTy (map used from tracking constants for symbols) to ↵Ted Kremenek
use the generic data map instead. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54860 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-17Added GRStateTrait.h, which includes boilerplate code for creating ↵Ted Kremenek
specializations of GRStateTrait<>. Modified GRStateTrait<ConstNotEq> in GRState to use the boilerplate in GRStateTrait<> for ImmutableMaps. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54859 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-16GRState:Ted Kremenek
- Remove ConstNotEq from GRState/GRStateManager (!= tracking uses GDM instead). - GRStateManager now can book-keep "contexts" (e.g., factory objects) for uses with data elements stored into the GDM. - Refactor pretty-printing of states to use GRState::Printer objects exclusively. This removed a huge amount of pretty-printing logic from GRExprEngine. CFRefCount - Simplified some API calls based on refinements to the GDM api. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54835 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-14Migrated retain/release checker to use the Generic Data Map in GRState (insteadTed Kremenek
of using CheckerState). Removed CheckerState from GRState. Added class GRStateRef which wraps GRState* and GRStateManager*. This is handy for generating new states with a single handle. Added member template set/get functions to GRStateRef/GRState/GRStateManager for accessing the Generic Data Map. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54788 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-13Renamed GRState::CheckerStatePrinter to GRState::Printer.Ted Kremenek
Updated checker state printer interface to allow transfer functions to return an arbitrary number of GRState::Printers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54762 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-13Rename ValueState.h -> GRState.hTed Kremenek
Rename ValueState.cpp -> GRState.cpp git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54722 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-13Rename ValueState -> GRState.Ted Kremenek
Rename ValueStateManager -> GRStateManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54721 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-13Fix memory leak found by Sam Bishop: delete WList in the dstor of ↵Ted Kremenek
GRCoreEngineImpl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54714 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-12Added GenericDataMap as a component of ValueState.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54704 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-07Added AssumeSymGT, AssumeSymGE, AssumeSymLT, AssumeSymLE to add some minor ↵Ted Kremenek
improvements to path-sensitivity. Right now we basically treat 'x > y' and 'x < y' as implying 'x != y', but this restriction will only inevitably apply to our must rudimentary value tracking component (we'll implement more advanced value reasoning later). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54493 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-31Enhanced path-sensitive return-of-stack-address check to print out the name ↵Ted Kremenek
of the variable whose address was returned. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54253 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-22Moved registration of basic path-sensitive checks from GRSimpleVals.cpp to ↵Ted Kremenek
GRExprEngineInternalChecks.cpp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53909 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-22Added path-sensitive checking for null pointer values passed to function ↵Ted Kremenek
arguments marked nonnull. This implements <rdar://problem/6069935> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53891 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-18Add panic support for NSAssertionHandler.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53758 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-18Fix regression by explicitly checking if we are negating a SymIntConstantVal.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53753 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
2008-07-18Remove dead method.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53748 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-17Move GRTransferFunc* into ValueStateManager, and move the assumption logic ↵Ted Kremenek
there as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53743 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-17Remove redundant logic.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53740 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
2008-07-14Refactor 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
2008-07-11Refactored 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
2008-07-10Remove unused class AnnotatedPath.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53413 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-10Move some environment methods from ValueState/ValueStateManager to ↵Ted Kremenek
Environment/EnvironmentManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53412 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-09Remove getParentMap() from GRExprEngine.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53343 91177308-0d34-0410-b5e6-96231b3b80d8
