genpreds.c (const_int_start, [...]): New variables.
gcc/
* genpreds.c (const_int_start, const_int_end): New variables.
(choose_enum_order): Output CONST_INT constraints before memory
constraints.
(write_tm_preds_h): Always define insn_const_int_ok_for_constraint.
Add CT_CONST_INT.
* ira-costs.c (record_reg_classes): Handle CT_CONST_INT.
* ira.c (ira_setup_alts): Likewise.
* lra-constraints.c (process_alt_operands): Likewise.
* recog.c (asm_operand_ok, preprocess_constraints): Likewise.
* reload.c (find_reloads): Likewise.
