2010-02-14Change LLVMConventionsChecker to accept an entire translation unit insteadTed Kremenek
of operating on each code decl. This exposes two flaws in AnalysisConsumer that should eventually be fixed: (1) It is not possible to associate multiple "actions" with a single command line argument. This will require the notion of an "analysis" group, and possibly tablegen support. (although eventually we want to support dynamically loading analyses as well) (2) AnalysisConsumer may not actually be scanning the declarations in namespaces. We'll experiment first in LLVMConventionsChecker before changing the behavior in AnalysisConsumer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96183 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-14Add new static analyzer for checking LLVM coding conventions: ↵Ted Kremenek
-analyzer-check-llvm-conventions Currently these checks are intended to be largely syntactical, but may get more sophisticated over time. As an initial foray into this brave new world, emit a static analyzer warning when binding a temporary 'std::string' to an 'llvm::StringRef' where the lifetime of the 'std::string' does not outlive the 'llvm::StringRef'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96147 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-14Two changes to AnalysisConsumer::HandleTopLevelSingleDecl():Ted Kremenek
(1) Since CXXMethodDecl subclasses FunctionDecl (and CXXDestructorDecl and CXXConversion subclass CXXMethodDecl), refactor switch statement to handle them all in one spot. (2) Use 'DeclarationName::getAsString()' to handle all functions that don't have simple identifiers (fixing a null dereference when scanning for specific functions). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96146 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

2010-01-05Remove references to 'Checker' and 'GRTransferFuncs' fromTed Kremenek
GRStateManager. Having these references was an abstraction violation, as they really should only be known about GRExprEngine. This change required adding a new 'ProcessAssume' callback in GRSubEngine. GRExprEngine implements this callback by calling 'EvalAssume' on all registered Checker objects as well as the registered GRTransferFunc object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92549 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-18Introduce caching of diagnostics in BugReporter. This provides extraTed Kremenek
pruning of diagnostics that may be emitted multiple times. This is accomplished by adding FoldingSet profiling support to PathDiagnostic, and then having BugReporter record what diagnostics have been issued. This was motived to a serious bug introduced by moving the 'divide-by-zero' checking outside of GRExprEngine into a separate 'Checker' class. When analyzing code using the '-fobjc-gc' option, a given function would be analyzed twice, but the second time various "internal checks" would be disabled to avoid emitting multiple diagnostics (e.g., "null dereference") for the same issue. The problem is that such checks also effect path pruning and don't just emit diagnostics. This resulted in an assertion failure involving a real divide-by-zero in some analyzed code where we would get an assertion failure in APInt because the 'DivZero' check was disabled and didn't prune the logic that resulted in the divide-by-zero in the analyzer. The implemented solution is somewhat of a hack, and may not perform extremely well. This will need to be cleaned up over time. As a regression test, 'misc-ps.m' has been modified so that its tests are run using -fobjc-gc to test this diagnostic pruning behavior. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82198 91177308-0d34-0410-b5e6-96231b3b80d8
