2008-03-07Increased worklist limit for GRSimpleVals.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48037 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-07Added --trim-path-graph to the driver to trim paths from the ExplodedGraphTed Kremenek
that are not related to error nodes. Fixed bug where we did not detect some NULL dereferences. Added "ExplodedGraph::Trim" to trim all nodes that cannot transitively reach a set of provided nodes. Fixed subtle bug in ExplodedNodeImpl where we could create predecessor iterators that included the mangled "sink" bit. The better fix is to integrate this bit into the void* for the wrapped State, not the NodeGroups representing a node's predecessors and successors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48036 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-07Patch by Nuno Lopes:Ted Kremenek
Added more comments for code processing attribute "format". Added more checks for corner cases, test cases, and warnings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48011 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-06remove two obsolete tests, not sure why my previous commit didn't commit the ↵Chris Lattner
removal. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47986 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-06Added boilerplate to execute the CF reference count checker (which isn't yet ↵Ted Kremenek
implemented). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47982 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47964 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47958 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05Fixed a horribly insidious bit-masking bug in the implementation ofTed Kremenek
ExplodedNode that would occasionally result in heap corruption. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47956 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-05remove the source location arguments to various target query methods.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47954 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05add analysis source files to project.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47953 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05Add the various pathsensitive headers to the project.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47952 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05ProgramEdge.h doesn't exist anymore.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47951 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05Reverted patch 47926 for ProgramPoint.h because it is currently buggy. May ↵Ted Kremenek
add back (fixed) later. Updated CFGStmtVisitor to be in accord with rr47913: CallExprs are no longer (automatically) block-level expressions in the CFG. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47935 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05Remove the first layer of support for "portability" warnings. This is Chris Lattner
theoretically useful, but not useful in practice. It adds a bunch of complexity, and not much value. It's best to nuke it. One big advantage is that it means the target interfaces will soon lose their SLoc arguments and target queries can never emit diagnostics anymore (yay). Removing this also simplifies some of the core preprocessor which should make it slightly faster. Ted, I didn't simplify TripleProcessor, which can now have at most one triple, and can probably just be removed. Please poke at it when you have time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47930 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05Added support for ProgramPoints to represent ExplodedNodes in anotherTed Kremenek
ExplodedGraph. This allows us to build "layered" ExplodedGraphs where one simulation is layered on another. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47926 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05move this into the right file.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47925 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05Plug-in transfer function "EvalCall" now takes as an argument the currentTed Kremenek
GRStmtNodeBuilder and is now responsible for adding its own nodes to the graph. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47923 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05Cleaned up typedefs involving StateTy so that we always use "StateTy*" ↵Ted Kremenek
instead of StateTy. This is conceptually much cleaner, as it shows that the state is always a pointer. It also makes it easier to marshall these values around across the internal APIs of the path-sensitive engine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47921 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-04Make GRStmtNodeBuilder only depend on StateTy, and not the type definitionTed Kremenek
of the entire checker. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47920 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-04Moved implementation of GRExprEngine::Nodify into GRStmtNodeBuilder. This willTed Kremenek
allow us to pass the builder to plug-in transfer functions and allow those functions to create intermediate nodes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47919 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-04Moved GRExprEngine::NodeSet out of GRExprEngine and made it a standalone ↵Ted Kremenek
class: ExplodedNodeSet. Made GRExprEngine::NodeSet a typedef of ExplodedNodeSet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47914 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-04CallExprs are now no longer block-level expressions in the CFG by construction.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47913 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-04For the transfer function for CallExpr, invalidate all argumentsTed Kremenek

2008-03-04For the transfer function of DeclStmt, for now initialize the values ofTed Kremenek
structs (local variables) to Unknown instead of Undefined. (added FIXME to initialize *members* of struct to undefined) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47901 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-04TargetInfo objects now own the TargetInfoImpl objects they refer to.Ted Kremenek
TargetInfo::AddSecondaryTarget is now private, as it is only used during object construction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47891 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-04Fixed insidious state propagation bug that would sometimes cause the stateTed Kremenek
to bifurcate at the wrong places and not propagate at others. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47876 91177308-0d34-0410-b5e6-96231b3b80d8
