    * genattrtab.c (struct attr_hash): Change hashcode type to unsigned.
    (attr_hash_add_rtx, attr_hash_add_string): Change hashcode parameter
    to unsigned.
    (attr_rtx_1): Change hashcode variable to unsigned.
    (attr_string): Likewise.  Perform first multiplication in unsigned
    type.
    * ifcvt.c (noce_try_store_flag_constants): Avoid signed integer
    overflows.
    * double-int.c (neg_double): Likewise.
    * stor-layout.c (set_min_and_max_values_for_integral_type): Likewise.
    * combine.c (force_to_mode): Likewise.
    * postreload.c (move2add_use_add2_insn, move2add_use_add3_insn,
    reload_cse_move2add, move2add_note_store): Likewise.
    * simplify-rtx.c (simplify_const_unary_operation,
    simplify_const_binary_operation): Likewise.
    * ipa-split.c (find_split_points): Initialize first.can_split
    and first.non_ssa_vars.
    * gengtype-state.c (read_state_files_list): Fix up check.
    * genautomata.c (reserv_sets_hash_value): Use portable rotation
    idiom.
java/
    * class.c (hashUtf8String): Compute hash in unsigned type.
    * javaop.h (WORD_TO_INT): Avoid signed integer overflow.
