2009-07-02StoreManagers: Use 'hasGlobalsStorage()' and 'hasParametersStorage()' instead ofTed Kremenek
directly consulting if a VarDecl is an implicit or actual parameter, a global, etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74716 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-02Add a separate MemSpaceRegion for function/method arguments passed on the stack.Ted Kremenek
This will simplify the logic of StoreManagers that want to specially reason about the values of parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74715 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-27Remove the last 'GetXXX' methods from GRStateManager.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74361 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74233 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-26Introduce a new concept to the static analyzer: SValuator.Ted Kremenek
GRTransferFuncs had the conflated role of both constructing SVals (symbolic expressions) as well as handling checker-specific logic. Now SValuator has the role of constructing SVals from expressions and GRTransferFuncs just handles checker-specific logic. The motivation is by separating these two concepts we will be able to much more easily create richer constraint-generating logic without coupling it to the main checker transfer function logic. We now have one implementation of SValuator: SimpleSValuator. SimpleSValuator is essentially the SVal-related logic that was in GRSimpleVals (which is removed in this patch). This includes the logic for EvalBinOp, EvalCast, etc. Because SValuator has a narrower role than the old GRTransferFuncs, the interfaces are much simpler, and so is the implementation of SimpleSValuator compared to GRSimpleVals. I also did a line-by-line review of SVal-related logic in GRSimpleVals and cleaned it up while moving it over to SimpleSValuator. As a consequence of removing GRSimpleVals, there is no longer a '-checker-simple' option. The '-checker-cfref' did everything that option did but also ran the retain/release checker. Of course a user may not always wish to run the retain/release checker, nor do we wish core analysis logic buried in the checker-specific logic. The next step is to refactor the logic in CFRefCount.cpp to separate out these pieces into the core analysis engine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74229 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73996 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-23- Add MemRegion::getMemorySpace()Ted Kremenek
- Change implementation of MemRegion::hasStackStorage()/hasHeapStorage() to use 'getMemorySpace()'. This avoids a double traversal up the region hierarchy and is simpler. - Add MemRegion::hasHeapOrStackStorage() as a slightly more efficient alternative to 'hasStackStorage() || hasHeapStorage()'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73977 91177308-0d34-0410-b5e6-96231b3b80d8

Clean up code with ValueManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73951 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-23Instead of setting the default value of the array region, bind the rest of theZhongxing Xu
array elements to 0 explicitly. Create 0 values with the element type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73946 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-23MemRegionManager: Migrate logic for getCodeTextRegion() over to using Zhongxing Xu
trait-based MemRegion creation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73941 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-23MemRegions:Ted Kremenek
- Embed a reference to MemRegionManager objects in MemSpaceRegion objects - Use this embedded reference for MemRegion objects to access ASTContext objects without external help - Use this access to ASTContext to simplify 'isBoundable' (no ASTContext& argument required) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73935 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-22Migrate factory methods for FieldRegion and ObjCIVarRegion creation to use theTed Kremenek
new generalized region-construction code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73921 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-22Refactor some of the logic in MemRegionManager for constructing regions usingTed Kremenek
member template functions and traits. The idea is to allow MemRegionManager to construct subclasses of MemRegion that aren't declared in MemRegion.h (e.g., checker-specific regions). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73917 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-19Remove more GetSVal/GetLValue methods in GRExprEngine/GRState, insteadTed Kremenek
preferring to use their replacements in GRState. This further unifies the code paths for such logic and leads to some code reduction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73771 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-19A further step of r73690: associate the cast-to type with the created symbol,Zhongxing Xu
because the type of the symbol is used to create the default range. We need the sign to be consistent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73756 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-18Move clients over from using GRStateManager::BindXXX and friends toTed Kremenek
GRState->bindXXX and friends (and constify some arguments along the way). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73740 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-18libAnalysis:Ted Kremenek
- Remove the 'isFeasible' flag from all uses of 'Assume'. - Remove the 'Assume' methods from GRStateManager. Now the only way to create a new GRState with an assumption is to use the new 'assume' methods in GRState. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73731 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-18When casting region, if we do not create an element region, record the cast-to Zhongxing Xu
type. When retrieving the region value, if we are going to create a symbol value, use the cast-to type if possible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73690 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73674 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-18Remove more dependencies on GRStateRef. As a consequence, we can nowTed Kremenek
pretty-print a GRState object anywhere it is referenced (instead of needing a GRStateRef of a GRStateManager handy). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73669 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73648 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-17Class 'Environment' no longer should subclass llvm::FoldingSetNode.Ted Kremenek
Environment hasn't been uniqued in a FoldingSet for some time, so this was just wasting a pointer in GRState. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73645 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-17Start moving in the direction of removing GRStateRef. Now eachTed Kremenek
GRState object has a direct reference to its GRStateManager, making the functionality of GRStateRef redunandant. This will lead to some nice API cleanup and code shrinking across libAnalysis. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73644 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-16RegionStoreManager:Ted Kremenek
- Add "sections" to RegionStoreManager.cpp to delineate functionality. - Add new function "CreateFieldsOnlyRegionStoreManager" that uses the new RegionStoreFeatures class to use a reduced set of features from RegionStoreManager (in this case, only field-sensitivity). This isn't completely hooked up yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73572 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-20* API change: we need to pass GRState to GRExprEngine::EvalBinOp() becauseZhongxing Xu
RegionStore needs to know the type of alloca region. * RegionStoreManager::EvalBinOp() now converts the alloca region to its first element region, as what is done to symbolic region. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72164 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-13Add ExplodedNode utility methods 'getLocationAs()' and 'getFirstPred()'Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71699 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-12Add logic for invalidating array region to CFRefCount.cpp. When invalidatingZhongxing Xu
array region, set its default value to conjured symbol. When retrieving its element, create new region value symbol for the element. Also fix some 80 columns violations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71548 91177308-0d34-0410-b5e6-96231b3b80d8
