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.

* ubsan.c (instrument_si_overflow): Likewise.
gcc/ada/
* gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION
as polynomial.
