2017-01-19PR13403 (+duplicates): implement C++ DR1310 (http://wg21.link/cwg1310).Richard Smith
Under this defect resolution, the injected-class-name of a class or class template cannot be used except in very limited circumstances (when declaring a constructor, in a nested-name-specifier, in a base-specifier, or in an elaborated-type-specifier). This is apparently done to make parsing easier, but it's a pain for us since we don't know whether a template-id using the injected-class-name is valid at the point when we annotate it (we don't yet know whether the template-id will become part of an elaborated-type-specifier). As a tentative resolution to a perceived language defect, mem-initializer-ids are added to the list of exceptions here (they generally follow the same rules as base-specifiers). When the reference to the injected-class-name uses the 'typename' or 'template' keywords, we permit it to be used to name a type or template as an extension; other compilers also accept some cases in this area. There are also a couple of corner cases with dependent template names that we do not yet diagnose, but which will also get this treatment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@292518 91177308-0d34-0410-b5e6-96231b3b80d8

Diasllow a declaration using the 'auto' type specifier from using two different meanings of it at once, or from declaring multiple functions with deduced return types or introducing multiple trailing return types. The standard does not technically disallow the multiple trailing return types case if all the declarators declare variables (such as function pointers with trailing return types), but we disallow that too, following the clear intent. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@291880 91177308-0d34-0410-b5e6-96231b3b80d8

2017-01-09Implement DR1388 (wg21.link/cwg1388).Richard Smith
This issue clarifies how deduction proceeds past a non-trailing function parameter pack. Essentially, the pack itself is skipped and consumes no arguments (except for those implied by an explicitly-specified template arguments), and nothing is deduced from it. As a small fix to the standard's rule, we do not allow subsequent deduction to change the length of the function parameter pack (by preventing extension of the explicitly-specified pack if present, and otherwise deducing all contained packs to empty packs). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@291425 91177308-0d34-0410-b5e6-96231b3b80d8

template parameters between deduction and substitution. The idea is to accept as many cases as possible, on the basis that substitution failure outside the immediate context is much more common during substitution than during implicit conversion sequence formation. This does not implement the partial ordering portion of DR1391, which so far appears to be misguided. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@290808 91177308-0d34-0410-b5e6-96231b3b80d8
2016-12-31[c++17] Implement P0522R0 as written. This allows a template template argumentRichard Smith
to be specified for a template template parameter whenever the parameter is at least as specialized as the argument (when there's an obvious and correct mapping from uses of the parameter to uses of the argument). For example, a template with more parameters can be passed to a template template parameter with fewer, if those trailing parameters have default arguments. This is disabled by default, despite being a DR resolution, as it's fairly broken in its current state: there are no partial ordering rules to cope with template template parameters that have different parameter lists, meaning that code that attempts to decompose template-ids based on arity can hit unavoidable ambiguity issues. The diagnostics produced on a non-matching argument are also pretty bad right now, but I aim to improve them in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@290792 91177308-0d34-0410-b5e6-96231b3b80d8
2016-12-28DR1315: a non-type template argument in a partial specialization is permittedRichard Smith

This is only a partial implementation; we retain the restriction that the argument must not be type-dependent, since it's unclear how that would work given the existence of other language rules requiring an exact type match in this context, even for type-dependent cases (a question has been raised on the core reflector). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@290647 91177308-0d34-0410-b5e6-96231b3b80d8

2016-12-08[c++1z] P0003R5: Removing dynamic exception specifications.Richard Smith
We continue to support dynamic exception specifications in C++1z as an extension, but produce an error-by-default warning when we encounter one. This allows users to opt back into the feature with a warning flag, and implicitly opts system headers back into the feature should they happen to use it. There is one semantic change implied by P0003R5 but not implemented here: violating a throw() exception specification should now call std::terminate directly instead of calling std::unexpected(), but since P0003R5 also removes std::unexpected() and std::set_unexpected, and the default unexpected handler calls std::terminate(), a conforming C++1z program cannot tell that we are still calling it. The upside of this strategy is perfect backwards compatibility; the downside is that we don't get the more efficient 'noexcept' codegen for 'throw()'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@289019 91177308-0d34-0410-b5e6-96231b3b80d8

2016-12-05DR1213: element access on an array xvalue or prvalue produces an xvalue. In theRichard Smith
latter case, a temporary array object is materialized, and can be lifetime-extended by binding a reference to the member access. Likewise, in an array-to-pointer decay, an rvalue array is materialized before being converted into a pointer. This caused IR generation to stop treating file-scope array compound literals as having static storage duration in some cases in C++; that has been rectified by modeling such a compound literal as an lvalue. This also improves clang's compatibility with GCC for those cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@288654 91177308-0d34-0410-b5e6-96231b3b80d8
