2009-09-05Basic support for representing elaborated type specifiersJohn McCall
directly in the AST. The current thinking is to create these only in C++ mode for efficiency. But for now, they're not being created at all; patch to follow. This will let us do things like verify that tags match during template instantation, as well as signal that an elaborated type specifier was used for clients that actually care. Optimally, the TypeLoc hierarchy should be adjusted to carry tag location information as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81057 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-04Improve the AST representation and semantic analysis for externDouglas Gregor
templates. We now distinguish between an explicit instantiation declaration and an explicit instantiation definition, and know not to instantiate explicit instantiation declarations. Unfortunately, there is some remaining confusion w.r.t. instantiation of out-of-line member function definitions that causes trouble here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@81053 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-03Improve template instantiation for member access expressions thatDouglas Gregor
involve qualified names, e.g., x->Base::f. We now maintain enough information in the AST to compare the results of the name lookup of "Base" in the scope of the postfix-expression (determined at template definition time) and in the type of the object expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80953 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-03Improved handling for dependent, qualified member access expressions, e.g.,Douglas Gregor
t->Base::f where t has a dependent type. We save the nested-name-specifier in the CXXUnresolvedMemberExpr then, during instantiation, substitute into the nested-name-specifier with the (transformed) object type of t, so that we get name lookup into the type of the object expression. Note that we do not yet retain information about name lookup into the lexical scope of the member access expression, so several regression tests are still disabled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80925 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-03This patch does the following.Fariborz Jahanian
1) Issue digsnostics in non-fragile ABI, when an expression evaluates to an interface type (except when it is used to access a non-fragile ivar). 2) Issue unsupported error in fragile ABI when an expression evaluates to an interface type (except when it is used to access a fragile ivar). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80860 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-02Add a wicked little test-case that illustrates what we have to dealDouglas Gregor
with to properly support member access expressions in templates. This test is XFAIL'd, because we get it completely wrong, but I've made the minimal changes to the representation to at least avoid a crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80856 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-02Rewrite of our handling of name lookup in C++ member access expressions, e.g.,Douglas Gregor
x->Base::f We no longer try to "enter" the context of the type that "x" points to. Instead, we drag that object type through the parser and pass it into the Sema routines that need to know how to perform lookup within member access expressions. We now implement most of the crazy name lookup rules in C++ [basic.lookup.classref] for non-templated code, including performing lookup both in the context of the type referred to by the member access and in the scope of the member access itself and then detecting ambiguities when the two lookups collide (p1 and p4; p3 and p7 are still TODO). This change also corrects our handling of name lookup within template arguments of template-ids inside the nested-name-specifier (p6; we used to look into the scope of the object expression for them) and fixes PR4703. I have disabled some tests that involve member access expressions where the object expression has dependent type, because we don't yet have the ability to describe dependent nested-name-specifiers starting with an identifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80843 91177308-0d34-0410-b5e6-96231b3b80d8

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
2009-09-02Replace 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
