re PR other/59545 (Signed integer overflow issues)
PR other/59545 * 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.
