2010-03-03Implement disambiguation of base class members via aDouglas Gregor
nested-name-specifier. For example, this allows member access in diamond-shaped hierarchies like: struct Base { void Foo(); int Member; }; struct D1 : public Base {}; struct D2 : public Base {}; struct Derived : public D1, public D2 { } void Test(Derived d) { d.Member = 17; // error: ambiguous cast from Derived to Base d.D1::Member = 17; // error: okay, modify D1's Base's Member } Fixes PR5820 and <rdar://problem/7535045>. Also, eliminate some redundancy between Sema::PerformObjectMemberConversion() and Sema::PerformObjectArgumentInitialization() -- the latter now calls the former. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97674 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-19Revert: "Change InitListExpr to allocate the array for holding references"Ted Kremenek
This was causing buildbot breakage. This reverts commit d46e952cc8cb8d9eed8657d9a0b267910a0f745a. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96652 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-19Change InitListExpr to allocate the array for holding referencesTed Kremenek
to initializer expressions in an array allocated using ASTContext. This plugs a memory leak when ASTContext uses a BumpPtrAllocator to allocate memory for AST nodes. In my mind this isn't an ideal solution; it would be nice to have a general "vector"-like class that allocates memory using ASTContext, but whose guts could be separated from the methods of InitListExpr itself. I haven't gone and taken this approach yet because it isn't clear yet if we'll eventually want an alternate solution for recylcing memory using by InitListExprs as we are constructing the ASTs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96642 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-09Migrate the mish-mash of declaration checks inDouglas Gregor
Sema::ActOnUninitializedDecl over to InitializationSequence (with default initialization), eliminating redundancy. More importantly, we now check that a const definition in C++ has an initilizer, which was an #if 0'd code for many, many months. A few other tweaks were needed to get everything working again: - Fix all of the places in the testsuite where we defined const objects without initializers (now that we diagnose this issue) - Teach instantiation of static data members to find the previous declaration, so that we build proper redeclaration chains. Previously, we had the redeclaration chain but built it too late to be useful, because... - Teach instantiation of static data member definitions not to try to check an initializer if a previous declaration already had an initializer. This makes sure that we don't complain about static const data members with in-class initializers and out-of-line definitions. - Move all of the incomplete-type checking logic out of Sema::FinalizeDeclaratorGroup; it makes more sense in ActOnUnitializedDecl. There may still be a few places where we can improve these diagnostics. I'll address that as a separate commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95657 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-31Rework base and member initialization in constructors, with severalDouglas Gregor
(necessarily simultaneous) changes: - CXXBaseOrMemberInitializer now contains only a single initializer rather than a set of initialiation arguments + a constructor. The single initializer covers all aspects of initialization, including constructor calls as necessary but also cleanup of temporaries created by the initializer (which we never handled before!). - Rework + simplify code generation for CXXBaseOrMemberInitializers, since we can now just emit the initializer as an initializer. - Switched base and member initialization over to the new initialization code (InitializationSequence), so that it - Improved diagnostics for the new initialization code when initializing bases and members, to match the diagnostics produced by the previous (special-purpose) code. - Simplify the representation of type-checked constructor initializers in templates; instead of keeping the fully-type-checked AST, which is rather hard to undo at template instantiation time, throw away the type-checked AST and store the raw expressions in the AST. This simplifies instantiation, but loses a little but of information in the AST. - When type-checking implicit base or member initializers within a dependent context, don't add the generated initializers into the AST, because they'll look like they were explicit. - Record in CXXConstructExpr when the constructor call is to initialize a base class, so that CodeGen does not have to infer it from context. This ensures that we call the right kind of constructor. There are also a few "opportunity" fixes here that were needed to not regress, for example: - Diagnose default-initialization of a const-qualified class that does not have a user-declared default constructor. We had this diagnostic specifically for bases and members, but missed it for variables. That's fixed now. - When defining the implicit constructors, destructor, and copy-assignment operator, set the CurContext to that constructor when we're defining the body. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94952 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-29Fix reference-binding when we have a reference to const volatile type;Douglas Gregor
previously, we were allowing this to bind to a temporary. Now, we don't; add test-cases and improve diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94831 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-29Fix reference binding of const lvalue references to bit-fields, whichDouglas Gregor
requires a temporary. Previously, we were building an initialization sequence that bound to the bit-field as if it were a real lvalue. Note that we previously (and still) diagnose binding of non-const references to bit-fields, as we should. There's no real way to test that this code is correct, since reference binding does not *currently* have any representation in the AST. This fix should make it easier for that to happen, so I've verified this fix with... Added InitializationSequence::dump(), to print an initialization sequence for debugging purposes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94826 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-08Change the printing of OR_Deleted overload results to print all the candidates,John McCall

This is reasonable because the most common use of deleted functions is to exclude some implicit conversion during calls; users therefore will want to figure out why some other options were excluded.
