	gcc            : ChangeLog recog.h recog.c caller-save.c reorg.c 
	                 reload1.c genattrtab.c final.c regmove.c 
	                 regclass.c reload.c 

Log message:
	* recog.h (enum op_type): Define.
	(constrain_operands): Adjust prototype.
	(recog_op_type): Declare new variable.
	* recog.c (recog_op_type): New variable.
	(insn_invalid_p): Allow modifying an asm statement after reload.
	(extract_insn): Set up recog_op_type.
	(constrain_operands): Lose INSN_CODE_NUM arg.  All callers changed.
	Don't compute operand types, use recog_op_type.
	Use the information computed by extract_insn instead of the previous
	method of finding it by insn code number.
	* caller-save.c (init_caller_save): Use extract_insn, not insn_extract.
	* reorg.c (fill_slots_from_thread): Likewise.
	* reload1.c (reload_as_needed): Likewise.
	(gen_reload): Likewise.
	(inc_for_reload): Likewise.
	(reload_cse_simplify_operands): Likewise.
	Use the information computed by extract_insn instead of the previous
	method of finding it by insn code number.
	* genattrtab.c (write_attr_case): Generate call to extract_insn, not
	insn_extract.
	* final.c (final_scan_insn): Use extract_insn, not insn_extract.
	(cleanup_operand_subregs): Use extract_insn, not insn_extract.
	Use the information computed by extract_insn instead of the previous
	method of finding it by insn code number.
	* regmove.c (find_matches): Likewise.  Change meaning of the return
	value to be nonzero if the optimization can be performed, zero if
	not.  All callers changed.
	Shorten some variable names to fix formatting problems.
	(regmove_optimize): Shorten some variable names to fix formatting
	problems.
	Use the information computed by extract_insn instead of the previous
	method of finding it by insn code number.
	* regclass.c (scan_one_insn): Likewise.
	(record_reg_classes): Don't compute operand types, use recog_op_type.
	* reload.c (find_reloads): Lose CONSTRAINTS1 variable; use
	recog_constraints instead.
