re PR debug/67664 (Duplicate AT_const_value attributes in some c++ cases.)
2015-09-21 Richard Biener <rguenther@suse.de> PR debug/67664 * dwarf2out.c (add_location_or_const_value_attribute): Remove attribute parameter. Early exit if either DW_AT_const_value or DW_AT_location are present already. (gen_variable_die): Adjust caller. (dwarf2out_late_global_decl): Likewise. * g++.dg/debug/dwarf2/pr67764.C: New testcase.
