2009-09-02Refactor the check for bad divide into a checker.Zhongxing Xu
Also fix a checker context bug: the Dst set is not always empty initially. Because in GRExprEngine::CheckerVisit(), *CurrSet is used repeatedly. So we removed the Dst.empty() condition in ~CheckerContext() when deciding whether to do autotransision. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80786 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-02When parsing typename specifiers (with either the identifier orDouglas Gregor
simple-template-id form), check whether the scope specifier is computable as a declaration context rather than checking whether it is dependent, so that we properly cope with members of the current instantiation. Improve testing for typename specifiers that terminate in a simpe-template-id. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80783 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-02Refactor bad callee check into a Checker.Zhongxing Xu
Now bad callee is checked as a PreVisit to the CallExpr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80771 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-02Still use BadArg bugtype in the checker. This saves us implement ↵Zhongxing Xu
registerInitialVisitors in the BugReport. When all internal bug checking logic are moved to checkers, BuiltinBug will not reference GRExprEngine, and FlushReports() will be not necessary, since all bugs are emitted into the equivalent classes immediately. For now just add a ctor with no arguments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80770 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-02Replace uses of ImmutableSet in SymbolReaper with DenseSet. This wasTed Kremenek
motivated from Shark profiles that shows that 'markLive' was very heavy when using --analyzer-store=region. On my benchmark file, this reduces the analysis time for --analyzer-store=region from 19.5s to 13.5s and for --analyzer-store=basic from 5.3s to 3.5s. For the benchmark file, this is a reduction of about 30% analysis time for both analysis modes (a huge win). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80765 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-02When adding a friend class declaration to the lookup tables, use the access ↵John McCall
specifier of any previous declaration in case we replace it in a class's declaration table. Fixes bug 4858. This sort of thing makes me reconsider putting friend declarations in declaration lists. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80750 91177308-0d34-0410-b5e6-96231b3b80d8

decl list, and remove some workarounds that were due to this. Thanks to Eli for pointing this out and providing the test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80745 91177308-0d34-0410-b5e6-96231b3b80d8
