Makefile.in (insn-extract.o): Fix dependencies.
* Makefile.in (insn-extract.o): Fix dependencies.
* genextract.c (main): Generate includes for insn-config.h and
recog.h.
Delete generation of declarations which are now in recog.h.
* genrecog.c (main): Delete generation of definitions which are
now in recog.c.
* local-alloc.c (block_alloc): Use extract_insn and the variables
it sets up instead of looking up values by insn_code.
* recog.c (recog_operand, recog_operand_loc, recog_dup_loc,
recog_dup_num): Define here instead of generating the definition in
genrecog.c.
(recog_n_operands, recog_n_dups, recog_n_alternatives,
recog_operand_mode, recog_constraints, recog_operand_address_p):
New variables.
(extract_insn): New function.
* recog.h (extract_insn): Declare function.
(which_alternative, recog_n_operands, recog_n_dups,
recog_n_alternatives, recog_operand_mode, recog_constraints,
recog_operand_address_p): Declare variables.
* regclass.c (n_occurrences): New static function.
* reload.c (n_occurrences): Delete function.
(find_reloads): Use extract_insn.
* reload.h (n_occurrences): Delete declaration.
