	(BFD_DEPENDENCIES): Likewise. Remove associated cases.
	(SHARED_LIBADD): Rename to...
	(CTF_LIBADD): ... this.  Stick in a suitable libiberty even when
	linking statically.
	* Makefile.am (libctf_nobfd_la_LIBADD): Adjust accordingly.
	libctf uses libintl.
	(libctf_la_LIBADD): Reference libbfd.la directly, not via
	BFD_LIBADD.
	(libctf_la_DEPENDENCIES): Remove.
	* Makefile.in: Regenerate.
	* configure: Likewise.

2021-01-05  Nick Alcock  <nick.alcock@oracle.com>

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

2021-01-05  Nick Alcock  <nick.alcock@oracle.com>

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

2021-01-05  Nick Alcock  <nick.alcock@oracle.com>

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

2021-01-05  Nick Alcock  <nick.alcock@oracle.com>

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

2021-01-05  Nick Alcock  <nick.alcock@oracle.com>

	* ctf-decl.c (ctf_decl_push): Don't print array decls backwards.
