I was trying to make sense of what sparc is doing for libthread_db
too.  It has:

  # define DB_THREAD_SELF \
    REGISTER (32, 32, 10 * 4, 0) \
    REGISTER (64, __WORDSIZE, (6 * 8) + (__WORDSIZE==64?0:4), 0)

Similarly s390 has:

  # define DB_THREAD_SELF REGISTER (32, 32, 18 * 4, 0) \
                          REGISTER (64, __WORDSIZE, 18 * 8, 0)

Could the __WORDSIZE in both of those be replaced with 64?

Thanks,
Gary
