2010-12-16Start migration of static analyzer to using theTed Kremenek
implicit lvalue-to-rvalue casts that John McCall recently introduced. This causes a whole bunch of logic in the analyzer for handling lvalues to vanish. It does, however, raise a few issues in the analyzer w.r.t to modeling various constructs (e.g., field accesses to compound literals). The .c/.m analysis test cases that fail are due to a missing lvalue-to-rvalue cast that will get introduced into the AST. The .cpp failures were more than I could investigate in one go, and the patch was already getting huge. I have XFAILED some of these tests, and they should obviously be further investigated. Some highlights of this patch include: - CFG no longer requires an lvalue bit for CFGElements - StackFrameContext doesn't need an 'asLValue' flag - The "VisitLValue" path from GRExprEngine has been eliminated. Besides the test case failures (XFAILed), there are surely other bugs that are fallout from this change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121960 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-04Although we currently have explicit lvalue-to-rvalue conversions, they'reJohn McCall
not actually frequently used, because ImpCastExprToType only creates a node if the types differ. So explicitly create an ICE in the lvalue-to-rvalue conversion code in DefaultFunctionArrayLvalueConversion() as well as several other new places, and consistently deal with the consequences throughout the compiler. In addition, introduce a new cast kind for loading an ObjCProperty l-value, and make sure we emit those nodes whenever an ObjCProperty l-value appears that's not on the LHS of an assignment operator. This breaks a couple of rewriter tests, which I've x-failed until future development occurs on the rewriter. Ted Kremenek kindly contributed the analyzer workarounds in this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120890 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
