gcc/ChangeLog:

	PR c++/37410
	* dwarf2out.c (dwarf2out_imported_module_or_decl): Split this
	  function in two, making it call a new and reusable
	  dwarf2out_imported_module_or_decl() that takes the containing
	  BLOCK of the declaration in argument.
	  (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
	* cp-gimplify.c (cp_gimplify_expr): For each USING_STMT
	  make sure an IMPORTED_DECL node is added to the BLOCK_VARS list
	  of the innermost containing BLOCK.

gcc/testsuite/ChangeLog:

	PR c++/37410
