[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.
for include/ChangeLog
PR debug/63240
* dwarf2.def (DW_AT_deleted, DW_AT_defaulted): New.
* dwarf2.h (enu dwarf_defaulted_attribute): New.
for gcc/ChangeLog
PR debug/63240
* langhooks-def.h
(LANG_HOOKS_FUNCTION_DECL_EXPLICIT_P): Const_tree-ify.
(LANG_HOOKS_FUNCTION_DECL_DELETED_P): Likewise.
(LANG_HOOKS_FUNCTION_DECL_DEFAULTED): Set default.
(LANG_HOOKS_DECLS): Add it.
* langhooks.h (struct lang_hooks_for_decls): Add
function_decl_defaulted. Const_tree-ify
function_decl_explicit_p and function_decl_deleted_p.
* dwarf2out.c (gen_subprogram_die): Add DW_AT_defaulted
attribute. Add DW_AT_deleted instead of DW_AT_GNU_deleted,
also at strict DWARF v5.
