address size and segment size fields into CIE... * dwarf2out.c (output_call_frame_info): For dw_cie_version >= 4 add also address size and segment size fields into CIE header. * unwind-dw2.c (extract_cie_info): Handle CIE version 4, as long as address size is the same as sizeof (void *) and segment size is 0. * unwind-dw2-fde.c (get_cie_encoding): Likewise. If address size or segment size is unexpected, return DW_EH_PE_omit. (classify_object_over_fdes): If get_cie_encoding returned DW_EH_PE_omit, return -1. (init_object): If classify_object_over_fdes returned -1, pretend there were no FDEs at all. From-SVN: r158589

* dwarf2out.c (mem_loc_descriptor): Use DW_OP_mod for UMOD instead of MOD, handle MOD using DW_OP_{over,over,div,mul,minus}. (loc_list_from_tree): Don't handle unsigned division. Handle signed modulo using DW_OP_{over,over,div,mul,minus}. * unwind-dw2.c (execute_stack_op): Handle DW_OP_mod using unsigned modulo instead of signed. * gcc.dg/cleanup-13.c: Expect DW_OP_mod to do unsigned modulo instead of signed, add a few new tests.
