bfd/

	* elf32-xtensa.c (xtensa_get_property_section_name): Delete.
	(xtensa_get_property_section): New.
	(xtensa_read_table_entries): Use xtensa_get_property_section.
	(relax_property_section, xtensa_get_property_predef_flags): Handle
	group name suffixes in property section names.
	(match_section_group): New.
gas/
	* config/tc-xtensa.c (FINI_LITERAL_SECTION_NAME): Delete.
	(INIT_LITERAL_SECTION_NAME): Delete.
	(lit_state struct): Remove segment names, init_lit_seg, and
	fini_lit_seg.  Add lit_prefix and current_text_seg.
	(init_literal_head_h, init_literal_head): Delete.
	(fini_literal_head_h, fini_literal_head): Delete.
	(xtensa_begin_directive): Move argument parsing to
	xtensa_literal_prefix function.
	(xtensa_end_directive): Deallocate lit_prefix field of lit_state.
	(xtensa_literal_prefix): Parse the directive argument here and
	record it in the lit_prefix field.  Remove code to derive literal
	section names.
	(linkonce_len): New.
	(get_is_linkonce_section): Use linkonce_len.  Check for any
	".gnu.linkonce.*" section, not just text sections.
	(md_begin): Remove initialization of deleted lit_state fields.
	(xtensa_reorder_segments, xtensa_post_relax_hook): Remove references
	to init_literal_head and fini_literal_head.
	(xtensa_move_literals): Likewise.  Skip literals for .init and .fini
	when traversing literal_head list.
	(match_section_group): New.
	(cache_literal_section): Rewrite to determine the literal section
	name on the fly, create the section and return it.
	(xtensa_switch_to_literal_fragment): Adjust for cache_literal_section.
	(xtensa_switch_to_non_abs_literal_fragment): Likewise.
	(xtensa_create_property_segments, xtensa_create_xproperty_segments):
	Use xtensa_get_property_section from bfd.
	(retrieve_xtensa_section): Delete.
	* doc/c-xtensa.texi (Xtensa Options): Fix --text-section-literals
	description to refer to plural literal sections and add xref to
	the Literal Directive section.
	(Literal Directive): Describe new rules for deriving literal section
	names.  Add footnote for special case of .init/.fini with
	--text-section-literals.
	(Literal Prefix Directive): Replace old naming rules with xref to the
	Literal Directive section.
ld/
	* emulparams/elf32xtensa.sh (.xt.prop): Add .xt.prop.*.
	* scripttempl/elfxtensa.sc (.text): Add .literal.*.
