 675
 676         * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
 677         FP_REGISTER_BYTES to compute offsets into the saved frame,
 678         since it fails for SPARC targets configured without any
 679         FP regs.  Instead, use DUMMY_STACK_REG_BUF_SIZE.

 687
 688         * Makefile.in configure configure.in:  Remove ENABLE_CLIBS,
 689         ENABLE_OBS, and THREAD_DB_OBS.  These are consolidated into LIBS
 690         and CONFIG_OBS.
 691         * configure configure.in:  Clean up test cases around thread support.
 692 start-sanitize-v850
 693         * configure.tgt (v850-*-*):  Include v850ice.o and v850.lib if
 694         host is Windows.
 695 end-sanitize-v850
 696         * c-valprint.c ch-valprint.c cp-valprint.c eval.c expprint.c
 697         printcmd.c valops.c value.h values.c:  Add bfd_section arg to
 698         value_at and value_at_lazy.
 699         * coffread.c dbxread.c elfread.c mdebugread.c minsyms.c symtab.h:
 700         Add bfd_section arg to prim_record_minimal_symbol_and_info.
 701         * corefile.c gdbcore.h printcmd.c valops.c:  Use read_memory_section
 702         instead of read_memory.  It takes a bfd_section arg.
 703         * coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h:  Remove
 704         unnecessary cast for assignment of struct dbx_symfile_info.
 705         Struct objfile now uses a real pointer instead of PTR for this
 706         element.
 707         * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
 708         text, data and bss into dbx_symfile_info.
 709         * exec.c (xfer_memory):  Handle transfers for user-specified
 710         sections.
 711         * findvar.c (read_var_value locate_var_value):  Copy bfd section
 712         from the symbol to the value.
 713         * gdb-stabs.h:  Add section pointers for text, data and bss
 714         sections.
 715         * maint.c (translate address command):  Add test code for overlay
 716         address translation.
 717         * printcmd.c (do_examine do_one_display):  Now takes a bfd section
 718         arg.
 719         * (print_formatted x_command):  Record current section along with
 720         current address for repeated commands.
 721         * sparc-nat.c (fetch_inferior_registers):  Change
 722         target_xfer_memory to target_{read write}_memory to allow changes
 723         to target_xfer_memory interface for section info.
 724         * symmisc.c (dump_msymbols print_symbol):  Print section
 725         assocaited with symbol.
 726         * symtab.c (fixup_symbol_section):  New routine to
 727         add section info to symbols returned by lookup_symbol.
 728         * symtab.h (struct general_symbol_info):  Add bfd section to
 729         symbols.
 730         * target.c target.h (target_xfer_memory):  Add bfd section to
 731         args.
 732         * (target_read_memory_section):  New routine to read data from a
 733         specific section.
 734         * (target_memory_bfd_section):  New global variable to pass bfd
 735         section in to targets.
 736         * valarith.c (value_add value_addr value_array):  Preserve bfd
 737         section when computing new value.
 738         * value.h (struct value):  Add bfd section to values.
 739         * values.c (allocate_value value_copy):  Initialize/preserve bfd
 740         section.
 741         * (unpack_double):  Clean up _MSC_VER conditionals to remove
 742         duplicate code.
 743 start-sanitize-v850
 744         * v850ice.c:  New module to support communication with NEC's
 745         PC-based ICE.
 746         * config/v850/tm-v850.h (REGISTER_NAMES):  Replace sp, gp, fp, and
 747         ep names with rxx names.  sp and fp are renamed via a different
 748         mechanism.

 752
 753         * mn10300-tdep.c (mn10300_push_arguments): rewrote,
 754         also removed code elsewhere that made use of RP_REGNUM.
 755         * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
 756         ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
 757         arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
 758         EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
