(have_special_memory_constraints, special_memory_start): New static vars. (special_memory_end): Ditto. (add_constraint): Add new arg is_special_memory. Add code to process its true value. Update have_special_memory_constraints. (process_define_constraint): Pass the new arg. (process_define_register_constraint): Ditto. (choose_enum_order): Process special memory. (write_tm_preds_h): Generate enum const CT_SPECIAL_MEMORY and function insn_extra_special_memory_constraint. (main): Process DEFINE_SPECIAL_MEMORY_CONSTRAINT. * gensupport.c (process_rtx): Process DEFINE_SPECIAL_MEMORY_CONSTRAINT. * ira-costs.c (record_reg_classes): Process CT_SPECIAL_MEMORY. * ira-lives.c (single_reg_class): Use insn_extra_special_memory_constraint. * ira.c (ira_setup_alts): Process CT_SPECIAL_MEMORY. * lra-constraints.c (process_alt_operands): Ditto.
