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

2009-11-10SizeofPointerChecker: Many false positives have the form 'sizeof *p'. Zhongxing Xu
This is reasonable because people know what they are doing when they intentionally dereference the pointer. So now we only emit warning when a pointer variable is use literally. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86673 91177308-0d34-0410-b5e6-96231b3b80d8
