* Implement DR1330 in C++11 mode, to support libstdc++4.7 which uses it.Richard Smith2012-04-1721-541/+872
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a new flavor of exception specification, EST_Uninstantiated. A function type with this exception specification carries a pointer to a FunctionDecl, and the exception specification for that FunctionDecl is instantiated (if needed) and used in the place of the function type's exception specification. When a function template declaration with a non-trivial exception specification is instantiated, the specialization's exception specification is set to this new 'uninstantiated' kind rather than being instantiated immediately. Expr::CanThrow has migrated onto Sema, so it can instantiate exception specs on-demand. Also, any odr-use of a function triggers the instantiation of its exception specification (the exception specification could be needed by IRGen). In passing, fix two places where a DeclRefExpr was created but the corresponding function was not actually marked odr-used. We used to get away with this, but don't any more. Also fix a bug where instantiating an exception specification which refers to function parameters resulted in a crash. We still have the same bug in default arguments, which I'll be looking into next. This, plus a tiny patch to fix libstdc++'s common_type, is enough for clang to parse (and, in very limited testing, support) all of libstdc++4.7's standard headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154886 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement C++11 [expr.prim.general]p3, which permits the use of 'this'Douglas Gregor2012-04-1620-91/+551
| | | | | | | | | | | | | | | | | | | | | | | | | in the declaration of a non-static member function after the (optional) cv-qualifier-seq, which in practice means in the exception specification and late-specified return type. The new scheme here used to manage 'this' outside of a member function scope is more general than the Scope-based mechanism previously used for non-static data member initializers and late-parsesd attributes, because it can also handle the cv-qualifiers on the member function. Note, however, that a separate pass is required for static member functions to determine whether 'this' was used, because we might not know that we have a static function until after declaration matching. Finally, this introduces name mangling for 'this' and for the implicit 'this', which is intended to match GCC's mangling. Independent verification for the new mangling test case would be appreciated.

* Fix tests that weren't actually verifying anything.David Blaikie2012-04-156-9/+9
| | | | | | | | | | | | | | Passing -verify to clang without -cc1 or -Xclang silently passes (with a printed warning, but lit doesn't care about that). This change adds -cc1 or, as is necessary in one case, -Xclang to fix this so that these tests are actually verifying as intended. I'd like to change the driver so this kind of mistake could not be made, but I'm not entirely sure how. Further, since the driver only warns about unknown flags in general, we could have similar bugs with a misspellings of arguments that would be nice to find. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154776 91177308-0d34-0410-b5e6-96231b3b80d8
