Richard Smith a91de375f2 Promote a warning on ill-formed code (redeclaration missing an exception ... specification) to an error. No compiler other than Clang seems to allow this, and it doesn't seem like a useful thing to accept as an extension in general. The current behavior was added for PR5957, where the problem was specifically related to mismatches of the exception specification on the implicitly-declared global operator new and delete. To retain that workaround, we downgrade the error to an ExtWarn when the declaration is of a replaceable global allocation function. Now that this is an error, stop trying (and failing) to recover from a missing computed noexcept specification. That recovery didn't work, and led to crashes in code like the added testcase. llvm-svn: 248867		2015-09-30 00:48:50 +00:00
