2016-01-15  Richard Biener  <rguenther@suse.de>

	PR debug/69137
	* dwarf2out.c (add_linkage_name_raw): New function split out from ...
	(add_linkage_name): ... here.
	(gen_typedef_die): Use add_linkage_name_raw instead of
	add_linkage_attr to delay DECL_ASSEMBLER_NAME computation
	if necessary.

	* g++.dg/lto/pr69137_0.C: New testcase.
