2008-04-16CF ref. count checker: Register memory leaks at the end of a path.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49824 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-16Small tweaks to EvalStore: pass an "RVal" instead of "LVal" for the TargetLV toTed Kremenek
represent possible stores to "Unknown." git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49811 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-16Implemented toll-free bridging support for CF Reference count checker.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49771 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-15Added initial boilerplate to support toll-free bridging in the ref-count ↵Ted Kremenek
checker. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49756 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14Treat calls to unresolved functions in the CF-ref count checker as callsTed Kremenek
to functions with NULL summaries. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49660 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14Hooked up the dead-store checker to the BugReporter interface. Now dead-storeTed Kremenek
warnings are emitted as part of the warnings registered by GRSimpleVals. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49658 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-11Add some boilerplate to report memory leaks at the end of an analyzed function.Ted Kremenek
Still need some boilerplate in BugReporter to report bugs at the end of a function (not associated with a particular statement). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49564 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-11Fix regression introduced by my last commit.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49556 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-11Changed behavior of how we handle "NULL" summaries: just callTed Kremenek
GRSimpleVals::EvalCal(), and don't change reference counts. Remove "getDoNothingSummary()", as a NULL summary does the same thing. Added temporary hack for the "Get" rule for objects that return a pointer type: treat them as non-owned CF objects. Added test case to detect the release of a non-owned object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49555 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-11Use RangedBugReport to report better ranges for reference count errors.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49552 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-10Fixed some logic errors in the CF ref count checker; we now can detect simpleTed Kremenek
use-after-release errors. Added test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49509 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-10Simplify CF ref. count checker state machine.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49505 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-10Fix some bonehead bugs in summary generation in CFRefCount.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49503 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-10Refactored all logic to run the GRSimpleVals and CFRef checker into a commonTed Kremenek
code path in the clang driver. Renamed options --grsimple to -checker-simple and -check-cfref to -checker-cfref. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49500 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-10CFRefCount analysis now properly calls "EmitWarnings" after analyzing a ↵Ted Kremenek
function. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49488 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-09Hooked up initial reference-count checks to the BugReporter interface.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49455 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-09Major refactoring/cleanup of GRExprEngine, ExplodedGraph, and BugReporter.Ted Kremenek
Bugs are now reported using a combination of "BugType" (previously BugDescription) and Bug "BugReport" objects, which are fed to BugReporter (which generates PathDiagnostics). This provides a far more modular way of registering bug types and plugging in diagnostics. GRExprEngine now owns its copy of GRCoreEngine, and is not owned by the ExplodedGraph. ExplodedGraph is no longer templated on the "checker", but instead on the state contained in the nodes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49453 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-09Added some boilerplate for emitting warnings from the CF-reference count ↵Ted Kremenek
checker. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49414 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Inlined clang/Analysis/Analyses/GRSimpleVals.h into LocalCheckers.h and removedTed Kremenek
GRSimpleVals.h Added a PathDiagnosticClient option to the driver functions for the CFRefCountChecker and the GRSimpleVals analysis. Both analyses now accept a "-o" argument from the driver that specifies where HTML reports should be dumped. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48989 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-21Rename "Nodify" to "MakeNode"Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48659 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8
