Richard Smith d3b5c90865 Final piece of core issue 1330: delay computing the exception specification of ... a defaulted special member function until the exception specification is needed (using the same criteria used for the delayed instantiation of exception specifications for function temploids). EST_Delayed is now EST_Unevaluated (using 1330's terminology), and, like EST_Uninstantiated, carries a pointer to the FunctionDecl which will be used to resolve the exception specification. This is enabled for all C++ modes: it's a little faster in the case where the exception specification isn't used, allows our C++11-in-C++98 extensions to work, and is still correct for C++98, since in that mode the computation of the exception specification can't fail. The diagnostics here aren't great (in particular, we should include implicit evaluation of exception specifications for defaulted special members in the template instantiation backtraces), but they're not much worse than before. Our approach to the problem of cycles between in-class initializers and the exception specification for a defaulted default constructor is modified a little by this change -- we now reject any odr-use of a defaulted default constructor if that constructor uses an in-class initializer and the use is in an in-class initialzer which is declared lexically earlier. This is a closer approximation to the current draft solution in core issue 1351, but isn't an exact match (but the current draft wording isn't reasonable, so that's to be expected). llvm-svn: 160847		2012-07-27 04:22:15 +00:00
