2009-11-13Add clang-cc option "--analyzer-experimental-internal-checks". ThisTed Kremenek
option enables new "internal" checks that will eventually be turned on by default but still require broader testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@88671 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-30Add casts to avoid a bunch of unused expr warnings. (They aren't reported ↵Anders Carlsson
right now due to a bug that I intend to fix). Ted, please review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77630 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-29Remove 'StoreManager::OldCastRegion()', TypedViewRegion (which onlyTed Kremenek
OldCastRegion used), and the associated command line option '-analyzer-store=old-basic-cast'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77509 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-10Switch BasicStoreManager to use the new CastRegion implementation by default,Ted Kremenek
and replace the 'clang-cc' option '-analyzer-store=basic-new-cast' with '-analyzer-store=basic-old-cast'. We'll keep the old CastRegion implementation around for a little while for regression testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75209 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
2009-06-11Bind the mistakenly generated nonloc::SymbolVal to struct correctly. See theZhongxing Xu
comments for added test case for details. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73189 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-20Treat AllocaRegion as SymbolicRegion in RegionStore::Retrieve().Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72166 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-20Add comments to test case.Zhongxing Xu

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
2009-05-12Add 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
2009-05-04Per conversations with Zhongxing, add an 'element type' toTed Kremenek
ElementRegion. I also removed 'ElementRegion::getArrayRegion', although we may need to add this back. This breaks a few test cases with RegionStore: - 'array-struct.c' triggers an infinite recursion in RegionStoreManager. Need to investigate. - misc-ps.m triggers a failure with RegionStoreManager as we now get the diagnostic: 'Line 159: Uninitialized or undefined return value returned to caller.' There were a bunch of places that needed to be edit RegionStoreManager, and we may not be passing all the correct 'element types' down from GRExprEngine. Zhongxing: When you get a chance, could you review this? I could have easily screwed up something basic in RegionStoreManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70830 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-17Update several tests to explicitly use BasicConstraintManager as well as to ↵Ted Kremenek
use RangeConstraintManager with RegionStoreManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64854 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-17Static Analyzer driver/options (partial) cleanup:Ted Kremenek
- Move all analyzer options logic to AnalysisConsumer.cpp. - Unified specification of stores/constraints/output to be: -analyzer-output=... -analyzer-store=... -analyzer-constraints=... instead of -analyzer-range-constraints, -analyzer-store-basic, etc. - Updated drivers (ccc-analyzer, scan-builds, new ccc) to obey this new interface - Updated test cases to conform to new driver options git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64737 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-22Fix RegionStore::getLValueElement() to handle the case when the base region ↵Ted Kremenek
is not an ElementRegion (also do some cleanups of its core logic). This gets array-struct.c to work with RegionStore. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62781 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-13Add KillStruct to region store. Zhongxing Xu
- put the killed region in the kill set. - set its default value to unknown. - removes all bindings for its subregions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62138 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-13MemRegion:Ted Kremenek
- Overhauled the notion of "types" for TypedRegions. We now distinguish between the "lvalue" of a region (via getLValueRegion()) and the "rvalue" of a region (va getRValueRegion()). Since a region represents a chunk of memory it has both, but we were conflating these concepts in some cases, leading to some insidious bugs. - Removed AnonPointeeType, partially because it is unused and because it doesn't have a clear notion of lvalue vs rvalue type. We can add it back once there is a need for it and we can resolve its role with these concepts. StoreManager: - Overhauled StoreManager::CastRegion. It expects an *lvalue* type for a region. This is actually what motivated the overhaul to the MemRegion type mechanism. It also no longer returns an SVal; we can just return a MemRegion*. - BasicStoreManager::CastRegion now overlays an "AnonTypedRegion" for pointer-pointer casts. This matches with the MemRegion changes. - Similar changes to RegionStore, except I've added a bunch of FIXMEs where it wasn't 100% clear where we should use TypedRegion::getRValueRegion() or TypedRegion::getLValueRegion(). AuditCFNumberCreate check: - Now blasts through AnonTypedRegions that may layer the original memory region, thus checking if the actually memory block is of the appropriate type. This change was needed to work with the changes to StoreManager::CastRegion. GRExprEngine::VisitCast: - Conform to the new interface of StoreManager::CastRegion. Tests: - None of the analysis tests fail now for using the "basic store". - Disabled the tests 'array-struct.c' and 'rdar-6442306-1.m' pending further testing and bug fixing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60995 91177308-0d34-0410-b5e6-96231b3b80d8
