2002-09-27  Isamu Hasegawa  <isamu@yamato.ibm.com>

	* posix/regcomp.c (reg_free): Free the debug area.
	(re_compile_internal): Allocate debug area for the input string.
	(create_initial_state): Check the back references in initial states
	if they are really match null string in the initial state.
	(parse_reg_exp): Mark the dfa that the dfa can have plural matchings.
	(parse_expression): Likewise.
	(parse_bracket_exp): Likewise.
	* posix/regex_internal.c (re_node_set_intersect): Remove unused
	function.
	(re_node_set_contains): Change to return the index of node.
	* posix/regex_internal.h (re_backref_cache_entry): Change the members.
	(re_match_context_t): Likewise.
	(struct re_dfa_t): Likewise.
	(re_sift_context_t): New structure.
	* posix/regexec.c (match_ctx_clear_flag): New function.
	(sift_ctx_init): Likewise.
	(update_cur_sifted_state): Likewise.
	(add_epsilon_src_nodes): Likewise.
	(sub_epsilon_src_nodes): Likewise.
	(check_subexp_limits): Likewise.
	(search_subexp): Likewise.
	(sift_states_bkref): Likewise.
	(merge_state_array): Likewise.
	(sift_states_iter_bkref): Remove unused function.
	(add_epsilon_backreference): Remove unused function.
	(re_search_internal): Adapt new members and interfaces.
	(check_matching): Check the back references in initial states
	if they are really match null string in the initial state.
	(proceed_next_node): Change the evaluation of back references,
	since we have real registers here.
	(set_regs): Adapt new interface of proceed_next_node.
	(sift_states_backward): Add invocation of update_cur_sifted_state
	instead of add_epsilon_backreference.
	Add a sentinel to the outermost while loop.
	Move the handling of back references to sift_states_bkref function,
	since we can't handle some back references (e.g. a back reference
	which match NULL string) here.
	(transit_state_mb): Handle the new member max_mb_elem_len.
	(transit_state_bkref_loop): Move the evaluation of back references to
	search_subexp function, since we can't evaluate some back references
	(e.g. a back reference which can have plural matchings) here.
	(match_ctx_init): Adapt the new member.
	(match_ctx_add_entry): Adapt the new members.

	* elf/do-rel.h: Define macro DO_ELF_MACHINE_REL_RELATIVE for
	'elf_machine_rel_relative'
	(elf_dynamic_do_rel): Call DO_ELF_MACHINE_REL_RELATIVE macro
	instead of 'elf_machine_rel_relative'.
	* sysdeps/hppa/dl-machine.h:
	Define macro DO_ELF_MACHINE_REL_RELATIVE for
	'elf_machine_rel_relative' with extra map parameter
	required by HPPA.
	(elf_machine_rela_relative): Add plt relocation changes.
