2013-05-02[analyzer] RetainCountChecker: don't track through xpc_connection_set_context.Jordan Rose
It is unfortunate that we have to mark these exceptions in multiple places. This was already in CallEvent. I suppose it does let us be more precise about saying /which/ arguments have their retain counts invalidated -- the connection's is still valid even though the context object's isn't -- but we're not tracking the retain count of XPC objects anyway. <rdar://problem/13783514> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180904 91177308-0d34-0410-b5e6-96231b3b80d8

2013-05-02[analyzer] scan-build for WindowsAnton Yartsev
The patch allows Windows users to launch scan-build without any additional preparations in the same way as it described in http://clang-analyzer.llvm.org/scan-build.html. The only thing that should be done to make scan-build work from an arbitrary location is to add scan-build folder to the PATH environment variable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180900 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-01[analyzer] Consolidate constant evaluation logic in SValBuilder.Jordan Rose
Previously, this was scattered across Environment (literal expressions), ExprEngine (default arguments), and RegionStore (global constants). The former special-cased several kinds of simple constant expressions, while the latter two deferred to the AST's constant evaluator. Now, these are all unified as SValBuilder::getConstantVal(). To keep Environment fast, the special cases for simple constant expressions have been left in, but the main benefits are that (a) unusual constants like ObjCStringLiterals now work as default arguments and global constant initializers, and (b) we're not duplicating code between ExprEngine and RegionStore. This actually caught a bug in our test suite, which is awesome: we stop tracking allocated memory if it's passed as an argument along with some kind of callback, but not if the callback is 0. We were testing this in a case where the callback parameter had a default value, but that value was 0. After this change, the analyzer now (correctly) flags that as a leak! <rdar://problem/13773117> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180894 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-01[analyzer] Don't inline the [cd]tors of C++ iterators.Jordan Rose
This goes with r178516, which instructed the analyzer not to inline the constructors and destructors of C++ container classes. This goes a step further and does the same thing for iterators, so that the analyzer won't falsely decide we're trying to construct an iterator pointing to a nonexistent element. The heuristic for determining whether something is an iterator is the presence of an 'iterator_category' member. This is controlled under the same -analyzer-config option as container constructor/destructor inlining: 'c++-container-inlining'. <rdar://problem/13770187> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180890 91177308-0d34-0410-b5e6-96231b3b80d8

This doesn't appear to be the cause of the slowdown. I'll have to try a manual bisect to see if there's really anything there, or if it's just the bot itself taking on additional load. Meanwhile, this change helps with correctness.

2013-04-30[ms-cxxabi] Implement member pointer comparisonsReid Kleckner
Summary: Like Itanium, comparisons are basically bitwise comparisons of the two values, with an exception for null member function pointers. If two function pointers are null, only the function pointer field matters for comparison purposes. The rest of the bits can be arbitrary. We take advantage of this in isZeroInitializable(), and it may matter once we start emitting conversions.

2013-04-29[analyzer] Change PathPieces to be a wrapper around an ilist of (through ↵Ted Kremenek
indirection) PathDiagnosticPieces. Much of this patch outside of PathDiagnostics.h are just minor syntactic changes due to the return type for operator* and the like changing for the iterator, so the real focus should be on PathPieces itself. This change is motivated so that we can do efficient insertion and removal of individual pieces from within a PathPiece, just like this was a kind of "IR" for static analyzer diagnostics. We currently implement path transformations by iterating over an entire PathPiece and making a copy. This isn't very natural for some algorithms. We use an ilist here instead of std::list because we want operations to rip out/insert nodes in place, just like IR manipulation. This isn't being used yet, but opens the door for more powerful transformation algorithms on diagnostic paths. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180741 91177308-0d34-0410-b5e6-96231b3b80d8
