        FP_REGISTER_BYTES to compute offsets into the saved frame, 
        since it fails for SPARC targets configured without any

        current address for repeated commands.
        * sparc-nat.c (fetch_inferior_registers):  Change

        assocaited with symbol.
        * symtab.c (fixup_symbol_section):  New routine to
        add section info to symbols returned by lookup_symbol.

        symbols.
        * target.c target.h (target_xfer_memory):  Add bfd section to
        args.
        * (target_read_memory_section):  New routine to read data from a
        specific section.

        section when computing new value.
        * value.h (struct value):  Add bfd section to values.

start-sanitize-v850
        * v850ice.c:  New module to support communication with NEC's
        PC-based ICE.
        * config/v850/tm-v850.h (REGISTER_NAMES):  Replace sp, gp, fp, and
        ep names with rxx names.  sp and fp are renamed via a different
        mechanism.

Fri Jan  3 14:20:05 1997  Geoffrey Noer  <noer@cygnus.com>

        * mn10300-tdep.c (mn10300_push_arguments): rewrote,
        also removed code elsewhere that made use of RP_REGNUM.
        * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
        ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
