poly_int: GET_MODE_BITSIZE
This patch changes GET_MODE_BITSIZE 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_to_bits): Return a poly_uint16 rather than an unsigned short. (GET_MODE_BITSIZE): Return a constant if ONLY_FIXED_SIZE_MODES, or if measurement_type is polynomial. * calls.c (shift_return_value): Treat GET_MODE_BITSIZE as polynomial. * combine.c (make_extraction): Likewise. * dse.c (find_shift_sequence): Likewise. * dwarf2out.c (mem_loc_descriptor): Likewise. * expmed.c (store_integral_bit_field, extract_bit_field_1): Likewise. (extract_bit_field, extract_low_bits): Likewise. * expr.c (convert_move, convert_modes, emit_move_insn_1): Likewise. (optimize_bitfield_assignment_op, expand_assignment): Likewise. (store_expr_with_bounds, store_field, expand_expr_real_1): Likewise. * fold-const.c (optimize_bit_field_compare, merge_ranges): Likewise. * gimple-fold.c (optimize_atomic_compare_exchange_p): Likewise. * reload.c (find_reloads): Likewise. * reload1.c (alter_reg): Likewise. * stor-layout.c (bitwise_mode_for_mode, compute_record_mode): Likewise. * targhooks.c (default_secondary_memory_needed_mode): Likewise. * tree-if-conv.c (predicate_mem_writes): Likewise. * tree-ssa-strlen.c (handle_builtin_memcmp): Likewise. * tree-vect-patterns.c (adjust_bool_pattern): Likewise. * tree-vect-stmts.c (vectorizable_simd_clone_call): Likewise. * valtrack.c (dead_debug_insert_temp): Likewise. * varasm.c (mergeable_constant_section): Likewise. * config/sh/sh.h (LOCAL_ALIGNMENT): Use as_a <fixed_size_mode>. gcc/ada/ * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE as polynomial. gcc/c-family/ * c-ubsan.c (ubsan_instrument_shift): Treat GET_MODE_BITSIZE as polynomial.
