recog.h (enum op_type): Define.
* 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.
