Alexandre Oliva e366d7d807 [PR63240] generate debug info for defaulted member functions 
This implements <http://dwarfstd.org/ShowIssue.php?issue=141215.3>, a
proposal already accepted for inclusion in DWARF-5, but using
DW_AT_GNU_defaulted instead of DW_AT_defaulted as the attribute name,
because the attribute id for DW_AT_defaulted is not yet publicly
available.

Mark Wielaard 42bc352001 DWARF add DW_AT_noreturn on noreturn function subprogram. 
This implements the DWARFv5 noreturn proposal:
http://dwarfstd.org/ShowIssue.php?issue=140331.1

TREE_THIS_VOLATILE on a FUNCTION_DECL node means the function does not
return normally. This catches the traditional noreturn GNU attribute,
the C11 _Noreturn keyword and the C++11 [[noreturn]] attribute.

This relies on the DW_AT_noreturn constant defined in the DWARFv5 DRAFT:
http://www.dwarfstd.org/doc/dwarf5.20141029.pdf

gcc/ChangeLog

	* dwarf2out.c (gen_subprogram_die): Add DW_AT_noreturn when the
	function decl has TREE_THIS_VOLATILE.

	* g++.dg/debug/dwarf2/noreturn-function.C: New test.
