2010-02-01In C++, an initializer on a variable doesn't necessarily mean it's the ↵Sebastian Redl
definition. With that in mind, rename getDefinition to getAnyInitializer (to distinguish it from getInit) and reimplement it in terms of isThisDeclarationADefinition. Update all code to use this new function. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94999 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
