Bootstrap failure

[Neil Booth]

Hi Vlad,

Your just-committed patch

2002-05-05  Vladimir Makarov  <vmakarov@redhat.com>

	* genautomata.c (form_the_same_automaton_unit_lists_from_regexp,
	process_unit_to_form_the_same_automaton_unit_lists,
	form_the_same_automaton_unit_lists
	check_unit_distributions_to_automata): New prototypes and
	functions.
	(check_automata): Rename it into `check_automata_insn_issues'.
	(unit_decl): New fields `the_same_automaton_unit' and
	`the_same_automaton_message_reported_p'.
	(unit_decl_t): New typedef.
	(the_same_automaton_lists): New gloval variable.
	(unit_regexp, unit_set_el, units_array, units_cmp,
	output_get_cpu_unit_code_func): Use the typedef.
	(evaluate_max_reserv_cycles): Increment
	`description->max_insn_reserv_cycles'.
	(initiate_states): Don't increment `max_cycles_num'.
	(transform_insn_regexps): Move code around transformation of
	regexps from `generate'.
	(generate): Remove call of `transform_insn_regexps'.
	(expand_automata): Call `transform_insn_regexps' and
	`check_unit_distributions_to_automata'.  Check errors before
	`generate'.

	* config/sparc/ultra3.md (us3_a0, us3_a1): Move the units into
	automaton `ultrasparc3_1'.
	
appears to cause a bootstrap failure on i686-pc-linux-gnu:

./genattrtab ../../gcc/config/i386/i386.md > tmp-attrtab.c
Check description...done
Reservation transformation...done
