* Split libAnalysis into two libraries: libAnalysis and libChecker.Ted Kremenek2010-01-251-237/+0
| | | | | | | | | | | | | | | | | | | | | | | | | (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

* Refactor DereferenceChecker to use only the new Checker API instead ofTed Kremenek2009-11-111-8/+5
| | | | | | | | | | the old builder API. This percolated a bunch of changes up to the Checker class (where CheckLocation has been renamed VisitLocation) and GRExprEngine. ProgramPoint now has the notion of a "LocationCheck" point (with PreLoad and PreStore respectively), and a bunch of the old ProgramPoints that are no longer used have been removed. llvm-svn: 86798
