From 84c484545c5906ba55143e212b4a5275ab55889f Mon Sep 17 00:00:00 2001 From: Jordan Rose Date: Thu, 15 Nov 2012 19:11:27 +0000 Subject: [PATCH] [analyzer] Mark symbol values as dead in the environment. This allows us to properly remove dead bindings at the end of the top-level stack frame, using the ReturnStmt, if there is one, to keep the return value live. This in turn removes the need for a check::EndPath callback in leak checkers. This does cause some changes in the path notes for leak checkers. Previously, a leak would be reported at the location of the closing brace in a function. Now, it gets reported at the last statement. This matches the way leaks are currently reported for inlined functions, but is less than ideal for both. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168066 91177308-0d34-0410-b5e6-96231b3b80d8 --- .../Core/PathSensitive/ExprEngine.h | 43 +-- lib/StaticAnalyzer/Core/Environment.cpp | 4 + lib/StaticAnalyzer/Core/ExprEngine.cpp | 28 +- .../Core/ExprEngineCallAndReturn.cpp | 25 +- test/Analysis/malloc-plist.c | 274 +++++++++--------- test/Analysis/malloc.c | 5 + test/Analysis/plist-output-alternate.m | 67 ++++- 7 files changed, 262 insertions(+), 184 deletions(-) diff --git a/include/clang/StaticAnalyzer/Core/PathSensitive/ExprEngine.h b/include/clang/StaticAnalyzer/Core/PathSensitive/ExprEngine.h index 78b254222e..17de90e000 100644 --- a/include/clang/StaticAnalyzer/Core/PathSensitive/ExprEngine.h +++ b/include/clang/StaticAnalyzer/Core/PathSensitive/ExprEngine.h @@ -154,26 +154,33 @@ public: const ExplodedGraph& getGraph() const { return G; } /// \brief Run the analyzer's garbage collection - remove dead symbols and - /// bindings. + /// bindings from the state. /// - /// \param Node - The predecessor node, from which the processing should - /// start. - /// \param Out - The returned set of output nodes. - /// \param ReferenceStmt - Run garbage collection using the symbols, - /// which are live before the given statement. - /// \param LC - The location context of the ReferenceStmt. - /// \param DiagnosticStmt - the statement used to associate the diagnostic - /// message, if any warnings should occur while removing the dead (leaks - /// are usually reported here). - /// \param K - In some cases it is possible to use PreStmt kind.
