	  (dwarf2out_imported_module_or_decl_real): New function.
	  (decls_for_scope, gen_decl_die, dwarf2out_decl): Take
	  IMPORTED_DECL in account.
	* tree.def: Added IMPORTED_DECL node type.
	* tree.h: Added accessors for IMPORTED_DECL nodes.
	* tree.c (init_ttree): Initialise IMPORTED_DECL node type.

gcc/cp/ChangeLog:

	PR c++/37410
