From 73c6a2448f24d13e16f34d46095ef7ad4bd1f145 Mon Sep 17 00:00:00 2001 From: Serge Pavlov Date: Sun, 23 Aug 2015 10:22:28 +0000 Subject: Instantiate function declarations in instantiated functions. If a function declaration is found inside a template function as in: template void f() { void g(int x = T::v) except(T::w); } it must be instantiated along with the enclosing template function, including default arguments and exception specification. Together with the patch committed in r240974 this implements DR1484.
