dwarf2out.c (free_AT, free_die): New fns.
* dwarf2out.c (free_AT, free_die): New fns.
(remove_children): Call them.
(output_line_info): Disable removal of duplicate notes.
Generate minimal debug info for types with TYPE_DECL_SUPPRESS_INFO set.
* dwarf2out.c (gen_struct_or_union_type_die): TYPE_DECL_SUPPRESS_INFO
means pretend the type isn't defined.
Don't defer emitting types.
(gen_type_die_for_member): New fn.
(gen_decl_die): Call it.
(splice_child_die): New fn.
(gen_member_die): Call it rather than generate duplicate dies.
Defer emitting information for the abstract instance of an inline
until we either inline it or emit an out-of-line copy.
* dwarf2out.c (decl_ultimate_origin): Ignore DECL_ABSTRACT_ORIGIN
from output_inline_function if DECL_ABSTRACT is also set.
(block_ultimate_origin): Likewise.
(gen_abstract_function): New fn.
(gen_decl_die, gen_inlined_subroutine_die): Call it.
(gen_subprogram_die): An abstract instance is not a declaration
just because it doesn't match current_function_decl. Don't abort
because DECL_DEFER_OUTPUT isn't set. Do abort if a declaration
has an abstract origin.
* toplev.c (rest_of_compilation): Don't emit dwarf2 info for the
abstract instance here.
