   6         routines.
   7         * remote-e7000.c: Fix sync code to timeout if unable to sync.
   8         Change sync code to report status while trying to sync-up
   9         with hardware.  Add debugging output and document.

  16         chain as a parameter.  Extract this generic code from the cleanup
  17         routines into separate funtions (*_my_cleanup).  Keep old
  18         functionality by passing "cleanup_chain" to the new funtions.
  19         Define the cleanup chain "final_cleanup_chain" to be a cleanup
  20         chain which will be executed only when gdb exits.  Add functions
  21         (*_final_cleanup) to match the original (*_cleanup) functions.
  22         (pollquit, quit, notice_quit): Fix to read cntl-C from the
  23         Windows message queue.

 322
 323         * blockframe.c (frameless_look_for_prologue):  Mark frames
 324         with a zero PC as frameless to improve backtraces from core dumps
 325         caused by dereferencing a NULL function pointer.

 332
 333         * mn10300-tdep.c: made a lot more generic, ripping out code
 334         from copied target (no more mn10300_scan_prologue,
 335         init_extra_frame_info, and mn10300_fix_call_dummy calls)
 336         * config/mn10300/tm-mn10300.h: undefine INIT_EXTRA_FRAME_INFO
 337         and INIT_FRAME_PC macros

 340
 341         * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
 342         FP_REGISTER_BYTES to compute offsets into the saved frame,
 343         since it fails for SPARC targets configured without any
 344         FP regs.  Instead, use DUMMY_STACK_REG_BUF_SIZE.

 346 Mon Jan  6 11:15:14 1997  Stu Grossman  (grossman@critters.cygnus.com)
 347
 348         * symtab.c (fixup_symbol_section):  Handle NULL symbols without
 349         crashing.

 352
 353         * Makefile.in configure configure.in:  Remove ENABLE_CLIBS,
 354         ENABLE_OBS, and THREAD_DB_OBS.  These are consolidated into LIBS
 355         and CONFIG_OBS.
 356         * configure configure.in:  Clean up test cases around thread support.
 357 start-sanitize-v850
 358         * configure.tgt (v850-*-*):  Include v850ice.o and v850.lib if
 359         host is Windows.

 361         * c-valprint.c ch-valprint.c cp-valprint.c eval.c expprint.c
 362         printcmd.c valops.c value.h values.c:  Add bfd_section arg to
 363         value_at and value_at_lazy.
 364         * coffread.c dbxread.c elfread.c mdebugread.c minsyms.c symtab.h:
 365         Add bfd_section arg to prim_record_minimal_symbol_and_info.
 366         * corefile.c gdbcore.h printcmd.c valops.c:  Use read_memory_section
 367         instead of read_memory.  It takes a bfd_section arg.
 368         * coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h:  Remove
 369         unnecessary cast for assignment of struct dbx_symfile_info.
 370         Struct objfile now uses a real pointer instead of PTR for this
 371         element.
 372         * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
 373         text, data and bss into dbx_symfile_info.
 374         * exec.c (xfer_memory):  Handle transfers for user-specified
 375         sections.
 376         * findvar.c (read_var_value locate_var_value):  Copy bfd section
 377         from the symbol to the value.
 378         * gdb-stabs.h:  Add section pointers for text, data and bss
 379         sections.
 380         * maint.c (translate address command):  Add test code for overlay
 381         address translation.
 382         * printcmd.c (do_examine do_one_display):  Now takes a bfd section
 383         arg.
 384         * (print_formatted x_command):  Record current section along with
 385         current address for repeated commands.
 386         * sparc-nat.c (fetch_inferior_registers):  Change
 387         target_xfer_memory to target_{read write}_memory to allow changes
 388         to target_xfer_memory interface for section info.
 389         * symmisc.c (dump_msymbols print_symbol):  Print section
 390         assocaited with symbol.
 391         * symtab.c (fixup_symbol_section):  New routine to
 392         add section info to symbols returned by lookup_symbol.
 393         * symtab.h (struct general_symbol_info):  Add bfd section to
 394         symbols.
 395         * target.c target.h (target_xfer_memory):  Add bfd section to
 396         args.
 397         * (target_read_memory_section):  New routine to read data from a
 398         specific section.
 399         * (target_memory_bfd_section):  New global variable to pass bfd
 400         section in to targets.
 401         * valarith.c (value_add value_addr value_array):  Preserve bfd
 402         section when computing new value.
 403         * value.h (struct value):  Add bfd section to values.
 404         * values.c (allocate_value value_copy):  Initialize/preserve bfd
 405         section.
 406         * (unpack_double):  Clean up _MSC_VER conditionals to remove
 407         duplicate code.
 408 start-sanitize-v850
 409         * v850ice.c:  New module to support communication with NEC's
 410         PC-based ICE.
 411         * config/v850/tm-v850.h (REGISTER_NAMES):  Replace sp, gp, fp, and
 412         ep names with rxx names.  sp and fp are renamed via a different
 413         mechanism.

 417
 418         * mn10300-tdep.c (mn10300_push_arguments): rewrote,
 419         also removed code elsewhere that made use of RP_REGNUM.
 420         * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
 421         ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
 422         arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
 423         EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
