* When profiling Environment, also profile with AnalysisContext*, bacauseZhongxing Xu2010-03-041-0/+1
| | | | | | | | | | 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. llvm-svn: 97724

* Use a GDM to record the returned expression in the state when VisitReturnStmt.Zhongxing Xu2010-02-261-10/+28
| | | | | | | | | | | Use this information to find the returned value and bind it to CallExpr in ProcessCallExit. And there is no need to remove dead bindings in ProcessCallExit, because a. it would clean up the return value bound to CallExpr b. we still would do it in the next ProcessStmt(), where we would not misclean up the return value. llvm-svn: 97225

* Call inliner improvements:Zhongxing Xu2010-02-251-0/+26
| | | | | | | | | | | | | | 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. llvm-svn: 97122
* Add MacOSXAPIChecker, a meta checker to include various precondition checks ↵Ted Kremenek2010-02-251-0/+1
| | | | | | | | | | | | for calls to various MacOS X functions. The checks in BasicObjCFoundationChecks.cpp will gradually be migrated here. As a first check, check that when 'dispatch_once()' is passed a predicate value that has non-local storage. llvm-svn: 97116
* Add UnixAPIChecker, a meta checker to include various precondition checks ↵Ted Kremenek2010-02-251-0/+1
| | | | | | | | | | | for calls to various unix/posix functions, e.g. 'open()'. As a first check, check that when 'open()' is passed 'O_CREAT' that it has a third argument. llvm-svn: 97086

* Split libAnalysis into two libraries: libAnalysis and libChecker.Ted Kremenek2010-01-251-0/+3325
(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
