functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120873 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-03Fix an insidious bug in BugReporter whereTed Kremenek
a node in the trimmed graph might not always correctly map back to the original error node. This could cause a crash in some cases when flagging memory leaks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120795 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-03Handle any number of SourceRanges inside BugReporter::FlushReport.Argyrios Kyrtzidis
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120769 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-24Adjust method calls to reflect name changes inTed Kremenek
ImmutableSet/ImmtuableMap/ImmutableList APIs. Along the way, clean up some method names in the static analyzer so that they are more descriptive and/or start with lowercase letters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120071 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-16Refactored BugReporter to refer to EndNode as ErrorNode. We currently make ↵Tom Care
the assumption that EndNode == ErrorNode, but upcoming changes will break this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114065 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-16Introduce new CFGElement hierarchy to support C++ CFG, based on Marcin's patchZhongxing Xu
and discussions with Ted and Jordy. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114056 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-09Use FindReportInEquivalenceClass to identify all the nodes used for the ↵Ted Kremenek
trimmed graph (in BugReporter). This fixes a problem where a leak that happened to occur on both an exit() path and a non-exit() path was getting reported with the exit() path (which users don't care about). This fixes: <rdar://problem/8331641> leak reports should not show paths that end with exit() (but ones that don't end with exit()) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113524 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-07Remove Decl::getCompoundBody().Argyrios Kyrtzidis
This has 2 (slight) advantages: -Make explicit at getBody()'s callsite that we expect/handle only CompoundStmt and not CXXTryStmt. -Better tracking of Decl::getBody()'s callsites. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107771 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-17Add raw_ostream operators to NamedDecl for convenience. Switch over all ↵Benjamin Kramer
users of getNameAsString on a stream. The next step is to print the name directly into the stream, avoiding a temporary std::string copy. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101632 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
