2010-08-26De-memberify the VarDecl and FunctionDecl StorageClass enums.John McCall
This lets us remove Sema.h's dependency on Expr.h and Decl.h. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112156 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

2010-05-26Remove extents of dead symbolic regions when RemoveDeadBindings.Zhongxing Xu
This requires creating new persistent states due to the nature of GDM. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104668 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-26Introduce Type::isStructureOrClassType(), which does the obviousDouglas Gregor
thing. Audit all uses of Type::isStructure(), changing those calls to isStructureOrClassType() as needed (which is alsmost everywhere). Fixes the remaining failure in Boost.Utility/Swap. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102386 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-10Enhance basic store to also lazily symbolicate VarRegionsTed Kremenek
with an 'unknown' memory space. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98110 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-02[CFG]Ted Kremenek
After discussion with Zhongxing, don't force the initializer of DeclStmts to be block-level expressions. This led to some interesting fallout: [UninitializedValues] Always visit the initializer of DeclStmts (do not assume they are block-level expressions). [BasicStore] With initializers of DeclStmts no longer block-level expressions, this causes self-referencing initializers (e.g. 'int x = x') to no longer cause the initialized variable to be live before the DeclStmt. While this is correct, it caused BasicStore::RemoveDeadBindings() to prune off the values of these variables from the initial store (where they are set to uninitialized). The fix is to back-port some (and only some) of the lazy-binding logic from RegionStore to BasicStore. Now the default values of local variables are determined lazily as opposed to explicitly initialized. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97591 91177308-0d34-0410-b5e6-96231b3b80d8

no need to store a type with SymbolRegionValue. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97437 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

2010-01-25Split 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
