2008-09-20Add PostStore, a new ProgramPoint to distinguish between 'stores' and other ↵Ted Kremenek
PostStmts. GRExprEngine: Use PostStore in EvalStore. Use a second version of EvalStore in EvalBinaryOperator to associate the store with the expression on the LHS. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56383 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-18Implement second part of PR 2600: NSError** parameter may be null, and ↵Ted Kremenek
should be checked before being dereferenced. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56318 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-18Change implementation of NSError** coding-style check to be invoked at the ↵Ted Kremenek
end of the retain/release analysis. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56312 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-18Implemented one of the checks requested in PR 2600:Ted Kremenek
"Method accepting NSError** argument should have non-void return value to indicate that an error occurred." Test case written, but the header needs to be delta-debugged reduced. Will commit shortly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56297 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-16ProgramPoint now takes the space of two pointers instead of one. This change wasTed Kremenek
motivated because it became clear that the number of subclasses of ProgramPoint would expand and we ran out of bits to represent a pointer variant. As a plus of this change, BlockEdge program points can now be represented explicitly without using a cache of CFGBlock* pairs in CFG. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56245 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-03Store: (static analyzer)Ted Kremenek
- Change definition of store::Region and store::Binding (once again) to make them real classes that just wrap pointers. This makes them more strictly typed, and allows specific implementations of Regions/Bindings to just subclass them. - minor renamings to RegionExtent and its subclasses - added a bunch of doxygen comments StoreManager: (static analyzer) - added 'iterBindings', an iteration method for iterating over the bindings of a store. It that takes a callback object (acting like a poor man's closure). - added 'getRVal' version for store::Binding. Will potentially phase the other versions of GetRVal in StoreManager out. - reimplemented 'getBindings' to be non-virtual and to use 'iterBindings' BasicStoreManager: (static analyzer) - implemented 'iterBindings' for BasicStoreManager git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55688 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 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

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

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

2008-08-07Added 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

2008-07-18Renamed 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
