poly_int: GET_MODE_PRECISION
This patch changes GET_MODE_PRECISION from an unsigned short to a poly_uint16. 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * machmode.h (mode_precision): Change from unsigned short to poly_uint16_pod. (mode_to_precision): Return a poly_uint16 rather than an unsigned short. (GET_MODE_PRECISION): Return a constant if ONLY_FIXED_SIZE_MODES, or if measurement_type is not polynomial. (HWI_COMPUTABLE_MODE_P): Turn into a function. Optimize the case in which the mode is already known to be a scalar_int_mode. * genmodes.c (emit_mode_precision): Change the type of mode_precision from unsigned short to poly_uint16_pod. Use ZERO_COEFFS for the initializer. * lto-streamer-in.c (lto_input_mode_table): Use bp_unpack_poly_value for GET_MODE_PRECISION. * lto-streamer-out.c (lto_write_mode_table): Use bp_pack_poly_value for GET_MODE_PRECISION. * combine.c (update_rsp_from_reg_equal): Treat GET_MODE_PRECISION as polynomial. (try_combine, find_split_point, combine_simplify_rtx): Likewise. (expand_field_assignment, make_extraction): Likewise. (make_compound_operation_int, record_dead_and_set_regs_1): Likewise. (get_last_value): Likewise. * convert.c (convert_to_integer_1): Likewise. * cse.c (cse_insn): Likewise. * expr.c (expand_expr_real_1): Likewise. * lra-constraints.c (simplify_operand_subreg): Likewise. * optabs-query.c (can_atomic_load_p): Likewise. * optabs.c (expand_atomic_load): Likewise. (expand_atomic_store): Likewise. * ree.c (combine_reaching_defs): Likewise. * rtl.h (partial_subreg_p, paradoxical_subreg_p): Likewise. * rtlanal.c (nonzero_bits1, lsb_bitfield_op_p): Likewise. * tree.h (type_has_mode_precision_p): Likewise. * ubsan.c (instrument_si_overflow): Likewise. gcc/ada/ * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION as polynomial.
