gensupport.h (pred_data): Add a "num_codes" field.
gcc/
* gensupport.h (pred_data): Add a "num_codes" field.
(add_predicate_code): Declare.
* gensupport.c (add_predicate_code): New function.
(std_pred_table): Add an "allows_const_p" field.
(std_preds): Set this field for predicates that allow RTX_CONST_OBJs.
Remove the (incomplete) list of such codes from the codes field.
(init_predicate_table): Use add_predicate_code. Add all
RTX_CONST_OBJs if allows_const_p is true.
* genrecog.c (process_define_predicate): Use add_predicate_code.
