 322         * c-valprint.c ch-valprint.c cp-valprint.c eval.c expprint.c
 323         printcmd.c valops.c value.h values.c:  Add bfd_section arg to
 324         value_at and value_at_lazy.
 325         * coffread.c dbxread.c elfread.c mdebugread.c minsyms.c symtab.h:
 326         Add bfd_section arg to prim_record_minimal_symbol_and_info.
 327         * corefile.c gdbcore.h printcmd.c valops.c:  Use read_memory_section

 330         unnecessary cast for assignment of struct dbx_symfile_info.
 331         Struct objfile now uses a real pointer instead of PTR for this
 332         element.
 333         * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
 334         text, data and bss into dbx_symfile_info.
 335         * exec.c (xfer_memory):  Handle transfers for user-specified
 336         sections.
 337         * findvar.c (read_var_value locate_var_value):  Copy bfd section

 340         sections.
 341         * maint.c (translate address command):  Add test code for overlay
 342         address translation.
 343         * printcmd.c (do_examine do_one_display):  Now takes a bfd section
 344         arg.
 345         * (print_formatted x_command):  Record current section along with
 346         current address for repeated commands.
 347         * sparc-nat.c (fetch_inferior_registers):  Change
 348         target_xfer_memory to target_{read write}_memory to allow changes
 349         to target_xfer_memory interface for section info.
 350         * symmisc.c (dump_msymbols print_symbol):  Print section
 351         assocaited with symbol.
 352         * symtab.c (fixup_symbol_section):  New routine to
 353         add section info to symbols returned by lookup_symbol.
 354         * symtab.h (struct general_symbol_info):  Add bfd section to
 355         symbols.
 356         * target.c target.h (target_xfer_memory):  Add bfd section to
 357         args.
 358         * (target_read_memory_section):  New routine to read data from a
 359         specific section.
 360         * (target_memory_bfd_section):  New global variable to pass bfd
 361         section in to targets.
 362         * valarith.c (value_add value_addr value_array):  Preserve bfd
 363         section when computing new value.
 364         * value.h (struct value):  Add bfd section to values.
 365         * values.c (allocate_value value_copy):  Initialize/preserve bfd
 366         section.
 367         * (unpack_double):  Clean up _MSC_VER conditionals to remove
 368         duplicate code.
 369 start-sanitize-v850
 370         * v850ice.c:  New module to support communication with NEC's
 371         PC-based ICE.
 372         * config/v850/tm-v850.h (REGISTER_NAMES):  Replace sp, gp, fp, and
 373         ep names with rxx names.  sp and fp are renamed via a different
 374         mechanism.

 379         * mn10300-tdep.c (mn10300_push_arguments): rewrote,
 380         also removed code elsewhere that made use of RP_REGNUM.
 381         * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
 382         ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
 383         arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
 384         EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
