* Fix PR 7475 by enhancing the static analyzer to also invalidate bindings for ↵Ted Kremenek2010-07-011-12/+2
| | | | | | | | | | | 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. llvm-svn: 107423

* Split libAnalysis into two libraries: libAnalysis and libChecker.Ted Kremenek2010-01-251-0/+250
(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. llvm-svn: 94406
