 674         * Makefile.in configure configure.in:  Remove ENABLE_CLIBS,
 675         ENABLE_OBS, and THREAD_DB_OBS.  These are consolidated into LIBS
 676         and CONFIG_OBS.
 677         * configure configure.in:  Clean up test cases around thread support.
 678 start-sanitize-v850
 679         * configure.tgt (v850-*-*):  Include v850ice.o and v850.lib if
 680         host is Windows.

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

 738
 739         * mn10300-tdep.c (mn10300_push_arguments): rewrote,
 740         also removed code elsewhere that made use of RP_REGNUM.
 741         * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
 742         ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
 743         arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
 744         EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
