2010-10-13Teach the warning about unnamed/local types in template arguments toDouglas Gregor
actually walk the template argument type to find any unnamed/local types within it. Fixes PR6784. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116382 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-12Introduce support for emitting diagnostics (warnings + their notes)Douglas Gregor
that are suppressed during template argument deduction. This change queues diagnostics computed during template argument deduction. Then, if the resulting function template specialization or partial specialization is chosen by overload resolution or partial ordering (respectively), we will emit the queued diagnostics at that point. This addresses most of PR6784. However, the check for unnamed/local template arguments (which existed before this change) is still only skin-deep, and needs to be extended to look deeper into types. It must be improved to finish PR6784. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116373 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-02Move the "current scope" state from the Parser into Action. ThisDouglas Gregor
allows Sema some limited access to the current scope, which we only use in one way: when Sema is performing some kind of declaration that is not directly driven by the parser (e.g., due to template instantiatio or lazy declaration of a member), we can find the Scope associated with a DeclContext, if that DeclContext is still in the process of being parsed. Use this to make the implicit declaration of special member functions in a C++ class more "scope-less", rather than using the NULL Scope hack. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107491 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-13Rework when and how vtables are emitted, by tracking where vtables areDouglas Gregor
"used" (e.g., we will refer to the vtable in the generated code) and when they are defined (i.e., because we've seen the key function definition). Previously, we were effectively tracking "potential definitions" rather than uses, so we were a bit too eager about emitting vtables for classes without key functions. The new scheme: - For every use of a vtable, Sema calls MarkVTableUsed() to indicate the use. For example, this occurs when calling a virtual member function of the class, defining a constructor of that class type, dynamic_cast'ing from that type to a derived class, casting to/through a virtual base class, etc. - For every definition of a vtable, Sema calls MarkVTableUsed() to indicate the definition. This happens at the end of the translation unit for classes whose key function has been defined (so we can delay computation of the key function; see PR6564), and will also occur with explicit template instantiation definitions. - For every vtable defined/used, we mark all of the virtual member functions of that vtable as defined/used, unless we know that the key function is in another translation unit. This instantiates virtual member functions when needed. - At the end of the translation unit, Sema tells CodeGen (via the ASTConsumer) which vtables must be defined (CodeGen will define them) and which may be used (for which CodeGen will define the vtables lazily). From a language perspective, both the old and the new schemes are permissible: we're allowed to instantiate virtual member functions whenever we want per the standard. However, all other C++ compilers were more lazy than we were, and our eagerness was both a performance issue (we instantiated too much) and a portability problem (we broke Boost test cases, which now pass). Notes: (1) There's a ton of churn in the tests, because the order in which vtables get emitted to IR has changed. I've tried to isolate some of the larger tests from these issues. (2) Some diagnostics related to implicitly-instantiated/implicitly-defined virtual member functions have moved to the point of first use/definition. It's better this way. (3) I could use a review of the places where we MarkVTableUsed, to see if I missed any place where the language effectively requires a vtable. Fixes PR7114 and PR6564. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103718 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-03When computing the template arguments for the instantiation of aDouglas Gregor
friend function template, be sure to adjust the computed template argument lists based on the location of the definition of the function template: it's possible that the definition we're instantiating with and the template declaration that we found when creating the specialization are in different contexts, which meant that we would end up using the wrong template arguments for instantiation. Fixes PR7013; all Boost.DynamicBitset tests now pass. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102974 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-30Clean up our handling of local instantiation scopes, which keep trackDouglas Gregor
of the mapping from local declarations to their instantiated counterparts during template instantiation. Previously, we tried to do some unholy merging of local instantiation scopes that involved storing a single hash table along with an "undo" list on the side... which was ugly, and never handled function parameters properly. Now, we just keep separate hash tables for each local instantiation scope, and "combining" two scopes means that we'll look in each of the combined hash tables. The combined scope stack is rarely deep, and this makes it easy to avoid the "undo" issues we were hitting. Also, I've simplified the logic for function parameters: if we're declaring a function and we need the function parameters to live longer, we just push them back into the local instantiation scope where we need them. Fixes PR6990. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102732 91177308-0d34-0410-b5e6-96231b3b80d8

And, since I couldn't resist, collapse the two implementations of function-parameter instantiation into calls to a single, new function (Sema::SubstParmVarDecl), since the two had nearly identical code (and each had bugs the other didn't!). More importantly, factored out the semantic analysis of a parameter declaration into Sema::CheckParameter, which is called both by Sema::ActOnParamDeclarator (when parameters are parsed) and when a parameter is instantiated.
