 467         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
 468         to hook.  Otherwise send it to fputs.
 469         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
 470         the obvious.
 471         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
 472         to _filtered forms to make output appear in GUIs.  Replace all
 473         uses of SERIAL_READCHAR with readchar, which has better error
 474         checking.
 475         * (e7000_parse_device):  Add prototype.
 476         (readchar):  Improve doc.  Handle random serial errors.

 481         necessary.
 482         (e7000_open):  Split into two pieces.  Second part is
 483         e7000_start_remote, and is error protected.  Now, when we connect
 484         to the target, we setup the initial frame and registers so that
 485         the user gets an immediate indication of where the target is.

 487         (e7000_read_inferior_memory):  Handle errors better.
 488         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
 489         command names.  They show up when doing completion and confuse
 490         things horribly.
 491         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
 492         directly from Win32s and Win95.  Get rid of debugify crud.

 497         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 498         Download routine now switches to remote target automatically.
 499         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 500         up MSVC/Win32 problem.

 517         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 518         sim_wait where gdb is in a position to handle a long running
 519         function.
 520         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a

 586 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 587
 588         * procfs.c: Substantial (but incomplete) changes to support
 589         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 590         struct now has substructs like struct flt_ctl instead of
 591         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 592         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 593         still have the structs and multiple fds, but don't use the
 594         entire struct and the four fds all point to the same thing.
 595         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 596         procfs with reads/writes or use ioctl instead.  We use
 597         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 598         multiple fds or not.  PROC_NAME_FMT is split out into
 599         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 600         STATUS_PROC_NAME_FMT.
 601
 602         (procfs_notice_signals): now a necessary wrapper around
 603         (notice_signals): which are the new guts for noticing signals
 604         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 605         determine whether or not to attempt to open the ctl_fd.
 606         (procfs_read_status): new local function, reads procfs status
 607         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 608         (procfs_write_pckill): new local function, writes a PCKILL
 609         (unconditionally_kill_inferior): remove signo since we now
 610         just call procfs_write_pckill().
 611         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 612         (proc_iterate_over_mappings): the whole function is ifdefed
 613         on UNIXWARE to keep things readable.
 614
 615         Expanded the syscall_table to include new potential sysv4.2mp
 616         members.  Note that all ifdefs of UNIXWARE should be eliminated
 617         if possible or renamed to describe what's being selected for a
 618         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 619         IRIX specific code now also checks it's not UNIXWARE.
 620
 621         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 622         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 623         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 624         "/debug/%d" as PROC_NAME_FMT used to be

 636         lousy out-of-date clone of remote.c.

 645

 649         Make static.

 651         Record size of response to fetch registers command, use this to
 652         limit size of memory read and write commands.
 653         * (push_remote_target):  New function to make it possible to have
 654         another target switch to the remote target.
 655         * target.h:  Add prototype for push_remote_target.
 656         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 657         for hosts which default to unsigned chars (such as SGI's).
 658         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 659         handled automatically in remote.c.

 664         find_pc_sect_function(), find_pc_sect_partial_function(): new
 665         functions for debugging overlays; pc without section is ambiguous.
 666         * breakpoint.[ch]: add section pointer to breakpoint struct;
 667         add section argument to check_duplicates(); check section as well
 668         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 669         breakpoint_thread_match(), bpstat_stop_status()];
 670         add section argument to describe_other_breakpoints();
 671         use INIT_SAL() macro to zero-out new sal structures;
 672         make resolve_sal_pc() fix up the sal's section as well as its pc;
 673         match on section + pc in clear_command() and delete_breakpoint();
 674         account for overlay sections in insert_breakpoints(),
 675         remove_breakpoint() and breakpoint_re_set_one();
 676         all this to support overlays where a PC is not unique.
 677         * exec.c: change xfer_memory() to handle overlay sections.
 678         * findvar.c: change read_var_value() to handle overlay sections.
 679         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 680         * infcmd.c: jump_command() warns against jumping into an overlay
 681         that's not in memory.  Also use INIT_SAL() to initialize sals.
 682         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 683         overlay state information; Also use INIT_SAL() to init sals.
 684         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 685         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 686         memory read/writes in the range 600000 to a00000, and ff680000
 687         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 688         * maint.c: maintenance command "translate-address" supports overlays.
 689         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 690         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 691         this constitutes gdb's internal overlay mapping table.  Add macro
 692         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 693         Add function find_pc_sect_section().
 694         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 695         modify address_info() with overlay smarts; add function sym_info()
 696         to support the INFO SYMBOL command (translate address to symbol(s));
 697         modify disassemble_command() to work on unmapped overlays.
 698         * source.c: use INIT_SAL() to initialize sals.
 699         * symfile.[ch]: change generic_load() to use section's LMA address
 700         instead of VMA address, for overlay sections.
 701         Add numerous functions for finding a PC's section / overlay,
 702         translating between VMA and LMA address ranges, determining if an
 703         overlay section is mapped, etc.  Add several user commands for
 704         overlay debugging.  Add support for a "generic" form of automatically
 705         reading overlay mapping info from the inferior (based on the default
 706         (simple) overlay manager which Cygnus provides as an example).
 707         * symtab.[ch]: add functions find_pc_sect_symtab(),
 708         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 709         for lookup; modify lookup_symbol and decode_line_1() to use them;
 710         modify find_function_start_sal() to account for overlay sections;
 711         add macro INIT_SAL() for initializing struct symtab_and_line.
 712         * target.c: fix a comment in the declaration of target_ops.
