2010-12-02Merge ValueManager into SValBuilder.Ted Kremenek

2010-12-01Rename all 'EvalXXX' methods in libChecker toTed Kremenek
'evalXXX'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120609 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-01Rename 'SValuator' to 'SValBuilder'. The new nameTed Kremenek
reflects what the class actually does. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120605 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-26Rename CXXObjectRegion to CXXTempObjectRegion.Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120176 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-15Disallow the use of UnknownVal as the index for ElementRegions. UnknownVals ↵Ted Kremenek
can be used as the index when the value evaluation isn't powerful enough. By creating ElementRegions with UnknownVals as the index, this gives the false impression that they are the same element, when they really aren't. This becomes really problematic when deriving symbols from these regions (e.g., those representing the initial value of the index), since two different indices will get the same symbol for their binding. This fixes an issue with the idempotent operations checker that would cause two indices that are clearly not the same to make it appear as if they always had the same value. Fixes <rdar://problem/8431728>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113920 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-01Don't assert in the analyzer when analyze code does a byte load from a ↵Ted Kremenek
function's address. Fixes PR 8052. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112761 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16- Allow making ElementRegions with complex offsets (expressions or symbols) ↵Jordy Rose
for the purpose of bounds-checking. - Rewrite GRState::AssumeInBound to actually do that checking, and to use the normal constraint path. - Remove ConstraintManager::AssumeInBound. - Teach RegionStore and FlatStore to ignore those regions for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111116 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-11MemRegion can refer to ASTContext without external help.Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110784 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-03Makes GRState::makeWithStore private, to encourage clients to make store ↵Jordy Rose
changes through GRState instead of directly accessing the StoreManager. Also adds cover methods for InvalidateRegion(s) and EnterStackFrame to GRState. This is in preparation for proposed region change notifications. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110137 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-02Improve flat store: MemRegion::getAsOffset() computes a region's offset withinZhongxing Xu
the top-level object. FlatStore now can bind and retrieve element and field regions. PR7297 is fixed by flat store. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110020 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-01Fix PR 7475 by enhancing the static analyzer to also invalidate bindings for ↵Ted Kremenek
non-static global variables when calling a function/method whose impact on global variables we cannot accurately estimate. This change introduces two new MemSpaceRegions that divide up the memory space of globals, and causes RegionStore and BasicStore to consult a binding to the NonStaticGlobalsMemSpaceRegion when lazily determining the value of a global. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107423 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Analyzer: add support for CXXNewExpr.Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101771 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-07Fix crash in StoreManager::CastRegion() when the base region is a type with ↵Ted Kremenek
0 size. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100594 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-11Eliminate the ASTContext parameter from RecordDecl::getDefinition()Douglas Gregor
and CXXRecordDecl::getDefinition(); it's totally unnecessary. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95836 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-08Unify the implementation of getLValueElement of store managers.Zhongxing Xu
It's more sophisticated than the original one of BasicStore. But it does matter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95536 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-08Unify the implementation of getLValueIvar and getLValueField of store managers.Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95535 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-08Move common methods to the base StoreManager class.Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95534 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-08ASTContext is now a reference member of StoreManager.Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95531 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-05More GRState* -> Store changes.Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95360 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25Split libAnalysis into two libraries: libAnalysis and libChecker.Ted Kremenek
(1) libAnalysis is a generic analysis library that can be used by Sema. It defines the CFG, basic dataflow analysis primitives, and inexpensive flow-sensitive analyses (e.g. LiveVariables). (2) libChecker contains the guts of the static analyzer, incuding the path-sensitive analysis engine and domain-specific checks. Now any clients that want to use the frontend to build their own tools don't need to link in the entire static analyzer. This change exposes various obvious cleanups that can be made to the layout of files and headers in libChecker. More changes pending. :) This change also exposed a layering violation between AnalysisContext and MemRegion. BlockInvocationContext shouldn't explicitly know about BlockDataRegions. For now I've removed the BlockDataRegion* from BlockInvocationContext (removing context-sensitivity; although this wasn't used yet). We need to have a better way to extend BlockInvocationContext (and any LocationContext) to add context-sensitivty. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94406 91177308-0d34-0410-b5e6-96231b3b80d8
