Tue Jan 12 14:05:37 1999   David Edelsohn  <edelsohn@mhpcc.edu>
        * rs6000.c (print_operand, cases 'm' and 'M'): Do not depend on
        HOST_WIDE_INT word-size.
        (rs6000_stack_info): Remove redundant alignment of fpmem.
Tue Jan 12 14:05:37 1999   Richard Henderson  <rth@cygnus.com>
        * rs6000.c (short_cint_operand): Remove CONSTANT_P_RTX handling.
        (u_short_cint_operand, reg_or_cint_operand, logical_operand): Likewise.
        (input_operand): Adjust CONSTANT_P_RTX handling.
        * rs6000.h (PREDICATE_CODES): Remove CONSTANT_P_RTX references.
        * rs6000.md (movsi): Adjust CONSTANT_P_RTX handling.
        (movhi, movqi): Remove CONSANT_P_RTX handling.
        (movdi): Adjust CONSTANT_P_RTX handling.
