2010-03-25Add methods to remove a GDM entry.Zhongxing Xu
Instead of setting the ReturnExpr GDM to NULL, remove it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99470 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-23Since we now may have basicblocks with the same block is in different function,Zhongxing Xu
change the block counter map from unsigned -> unsigned to <StackFrameContext*, unsigned> -> unsigned. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99255 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-04When profiling Environment, also profile with AnalysisContext*, bacauseZhongxing Xu
we now may have identical states with different analysis context. Set the right AnalysisContext in state when entering and leaving a callee. With both of the above changes, we can pass the test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97724 91177308-0d34-0410-b5e6-96231b3b80d8

GRExprEngine::ProcessCallExit(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97129 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Call inliner improvements:Zhongxing Xu
This patch implements the CallEnter/CallExit idea of Ted. Add two interfaces to GRSubEngine: ProcessCallEnter, ProcessCallExit. The CallEnter program point uses caller's location context. The CallExit program point uses callee's location context. CallEnter is built by GRStmtNodeBuilder. CallExit is built by GREndPathNodeBuilder. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97122 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
