2011-08-15Rename GRState to ProgramState, and cleanup some code formatting along the way.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137665 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12Cleanup various declarations of 'Stmt*' to be 'Stmt *', etc. in libAnalyzer ↵Ted Kremenek
and libStaticAnalyzer[*]. It was highly inconsistent, and very ugly to look at. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137537 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12[analyzer] Introduce new MemRegion, "TypedValueRegion", so that we can ↵Ted Kremenek
separate TypedRegions that implement getValueType() from those that don't. Patch by Olaf Krzikalla! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137498 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-10Analyzer Core: In checkDeadSymbols checker callback, provide the state in ↵Anna Zaks
which the symbols are not yet deleted so that checkers could inspect them. Since we are now always creating a transition in ProcessStmt(), remove the logic for adding a transition when none was generated. TODO: the extra transitions will have to be removed; more cleanups; a checker that tests teh new fucntionality. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137273 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-06[analyzer] Change SymbolReaper to store region roots implied by the ↵Ted Kremenek
Environment, allowing it be queried when determining if symbols derived from regions are still live. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137005 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-28[analyzer] Overhaul how the static analyzer expects CFGs by forcing CFGs to ↵Ted Kremenek
be linearized only when used by the static analyzer. This required a rewrite of LiveVariables, and exposed a ton of subtle bugs. The motivation of this large change is to drastically simplify the logic in ExprEngine going forward. Some fallout is that the output of some BugReporterVisitors is not as accurate as before; those will need to be fixed over time. There is also some possible performance regression as RemoveDeadBindings will be called frequently; this can also be improved over time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136419 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-23remove unneeded llvm:: namespace qualifiers on some core types now that ↵Chris Lattner
LLVM.h imports them into the clang namespace. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135852 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-02Augment retain/release checker to not warn about tracked objects passed as ↵Ted Kremenek
arguments to C++ constructors. This is a stop-gap measure for Objective-C++ code that uses smart pointers to manage reference counts. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130711 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-19Change 'StoreRef' back to 'Store' in GRState, shrinking the size of GRState ↵Ted Kremenek
back by one pointer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126020 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-19Add 'StoreRef' smart pointer to allow more fine-grain memory lifetime ↵Ted Kremenek
control of Store objects. This yields a minor memory reduction (for larger functions) on Sqlite at the cost of slightly higher memory usage on some functions because of the increased size of GRState (which can be optimized). I expect the real memory savings from this enhancement will come when we aggressively canabilize more of the ExplodedGraph. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126012 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-10Split 'include/clang/StaticAnalyzer' into ↵Ted Kremenek
'include/clang/StaticAnalyzer/Core' and 'include/clang/StaticAnalyzer/Checkers'. This layout matches lib/StaticAnalyzer, which corresponds to two StaticAnalyzer libraries. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125251 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-08[analyzer] Move the files in lib/StaticAnalyzer to lib/StaticAnalyzer/Core.Argyrios Kyrtzidis
Eventually there will also be a lib/StaticAnalyzer/Frontend that will handle initialization and checker registration. Yet another library to avoid cyclic dependencies between Core and Checkers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125124 91177308-0d34-0410-b5e6-96231b3b80d8
