 655         * ctf-decl.c (ctf_decl_push): Exclude slices from the decl stack.
 656         * ctf-types.c (ctf_type_aname): No longer deal with slices here.
 657         * ctf-dump.c (ctf_dump_membstate_t) <cdm_toplevel_indent>: Constify.
 658         (CTF_FT_REFS): New.
 659         (CTF_FT_BITFIELD): Likewise.
 660         (CTF_FT_ID): Likewise.
 661         (ctf_dump_member): Do not do indentation here. Migrate the
 662         type-printing parts of this into...
 663         (ctf_dump_format_type): ... here, to be shared by all type printers.
 664         Get the errno value for non-representable types right.  Do not print
 665         bitfield info for non-bitfields.  Improve the format and indentation
 666         of other type output.  Shuffle spacing around to make all indentation
 667         either 'width of column' or 4 chars.
 668         (ctf_dump_label): Pass CTF_FT_REFS to ctf_dump_format_type.
 669         (ctf_dump_objts): Likewise.  Spacing shuffle.
 670         (ctf_dump_var): Likewise.
 671         (type_hex_digits): Migrate down in the file, to above its new user.
 672         (ctf_dump_type): Indent here instead.  Pass CTF_FT_REFS to
 673         ctf_dump_format_type. Don't trim off excess linefeeds now we no
 674         longer generate them.  Dump enumerated types.

 678         * ctf-types.c (ctf_type_resolve): Improve comment.
 679         (ctf_type_size): Yield ECTF_INCOMPLETE when applied to forwards.
 680         Emit errors into the right dict.
 681         (ctf_type_align): Likewise.
 682         * ctf-create.c (ctf_add_member_offset): Yield ECTF_INCOMPLETE
 683         when adding a member without explicit offset when this member, or
 684         the previous member, is incomplete.
 685         * ctf-dump.c (ctf_dump_format_type): Do not try to print the size of
 686         forwards.
 687         (ctf_dump_member): Do not try to print their alignment.

 691         * ctf-dump.c (ctf_dump_objts): Dump by calling ctf_dump_format_type.
 692         (ctf_dump_format_type): Don't emit the size for function objects.
 693         Dump the element type of arrays like we dump the pointed-to type of
 694         pointers, etc.

 698         * ctf-dump.c (ctf_dump_format_type): Add 0x to hex type IDs.
 699         (ctf_dump_header): Add 0x to the hex magic number.
 700         (ctf_dump_str): Add 0x to the hex string offsets.
 701         (ctf_dump_membstate_t) <cdm_toplevel_indent>: New.
 702         (ctf_dump_type): Adjust.  Free it when we're done.
 703         (type_hex_digits): New.
 704         (ctf_dump_member): Align output depending on the width of the type
 705         ID being generated.  Use printf padding, not a loop, to generate
 706         indentation.
