Description

This patch propagates the source location from a template function's definition to any already-instantiated declarations. It doesn't also copy it to the template_decl, even though that also has the wrong location, because maybe that's supposed to represent the declaration and not the definition. PR c++/46527 * gcc/cp/pt.c (instantiate_decl): Propagate the template's location to its instance. * gcc/testsuite/g++.dg/debug/dwarf2/pr46527.C: New.

As we discussed, it seems reasonable, but I don't know this area very well. 
Jason should give you a definitive answer.
