Richard Smith 2e32155b58 Instantiate exception specifications when instantiating function types (other ... than the type of a function declaration). We previously didn't instantiate these at all! This also covers the pathological case where the only mention of a parameter pack is within the exception specification; this gives us a second way (other than alias templates) to reach the horrible state where a type contains an unexpanded pack, but its canonical type does not. This is a re-commit of r219977: r219977 was reverted in r220038 because it hit a wrong-code bug in GCC 4.7.2. (That's gcc.gnu.org/PR56135, and affects any implicit lambda-capture of 'this' within a template.) r219977 was a re-commit of r217995, r218011, and r218053: r217995 was reverted in r218058 because it hit a rejects-valid bug in MSVC. (Incorrect overload resolution in the presence of using-declarations.) It was re-committed in r219977 with a workaround for the MSVC rejects-valid. r218011 was a workaround for an MSVC parser bug. (Incorrect desugaring of unbraced range-based for loop). llvm-svn: 221750		2014-11-12 02:00:47 +00:00
