2010-10-20Remove obsolete GRAuditor and GRSimpleAPICheck, which have been completely ↵Ted Kremenek
subsumed by the Checker interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116973 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-20Convert GRSimpleAPIChecks in BasicObjCFoundationChecks to be Checkers.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116971 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-30Added two new command line arguments:Marcin Swiderski
-cfg-add-implicit-dtors - sets CFG::BuildOptions::AddImplicitDtors for AnalysisCosumer to true, -cfg-add-initializers - sets CFG::BuildOptions::AddInitializers for AnalysisCosumer to true. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115142 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-29Change -analyzer-max-nodes to allow 0 as a parameter. This allows the ↵Tom Care
analyzer to completely analyze a worklist regardless of time taken. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115108 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-14Rename 'MaxLoop' to 'MaxVisit' in AnalysisManager to more correctly reflect ↵Tom Care
that we aborted analysis may not necessarily be due to a loop. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113862 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-18More PCH -> AST renaming.Sebastian Redl
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111472 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-11Have GRCoreEngine record the blocks where analysis was aborted because we ↵Ted Kremenek
visited a block too many times along a given path. This is to support the unreachable code analysis. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110755 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-03Add -cc1 option '-unoptimized-cfg' to toggle using a CFG (for static ↵Ted Kremenek
analysis) that doesn't prune CFG edges. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110087 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-22Make a bunch of new data structures for the new analysisZhongxing Xu
engine of the new translation unit. State marshal is there but no real work is done. End nodes are passed back. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109105 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-17Revert r108617, it broke the build.Benjamin Kramer
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108621 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-17Prepare the analyzer for the callee in another translation unit:Zhongxing Xu
Let AnalysisContext contain a TranslationUnit. Let CallEnter refer to an AnalysisContext instead of a FunctionDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108617 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-29Tweaker Checker::VisitEndAnalysis to have 'hasWorkRemaining' alsoTed Kremenek
be true if some paths were aborted because they exceeded the maximum loop unrolling count. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107209 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-23Add 'VisitEndAnalysis' callback to Checker class. This callback is called ↵Ted Kremenek
by GRExprEngine when the worklist algorithm has terminated. This allows some checkers to do a post-analysis phase after all paths have been analyzed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106689 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-14Move GRStmtNodeBuilder::MakeNode() out of line. No functionality change.Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101239 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
2010-03-05Remove reference to AnalysisContext in Environment. We already have ↵Zhongxing Xu
LocationContext information in ExplodedNode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97785 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

due to a Clang-on-Clang failure git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97162 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
