501 Fri Apr 18 17:25:10 1997 Stu Grossman (grossman@critters.cygnus.com)
502
503 * Makefile.in (SUBDIRS): Add mswin so that make cleanup cleans up
504 that directory.
505 * defs.h utils.c (error warning): Make message be const.
506 * main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr
507 to hook. Otherwise send it to fputs.
508 * monitor.c monitor.h (monitor_get_dev_name): New function. Does
509 the obvious.
510 * remote-e7000.c: Remove debugify stuff. Change printf, fprintf
511 to _filtered forms to make output appear in GUIs. Replace all
512 uses of SERIAL_READCHAR with readchar, which has better error
513 checking.
514 * (e7000_parse_device): Add prototype.
515 (readchar): Improve doc. Handle random serial errors.
516 (expect): Disable notice_quit code. It's busted. Remove
517 serial error handling (it's now handled in readchar). Remove
518 remote_debug echoing. That's handled in readchar as well.
519 (e7000_parse_device): Remove serial_flag arg. It's not
520 necessary.
521 (e7000_open): Split into two pieces. Second part is
522 e7000_start_remote, and is error protected. Now, when we connect
523 to the target, we setup the initial frame and registers so that
524 the user gets an immediate indication of where the target is.
525 (gch): Remove debug output. That's handled by readchar.
526 (e7000_read_inferior_memory): Handle errors better.
527 (_initialize_remote_e7000): Get rid of `<xxx>' things from
528 command names. They show up when doing completion and confuse
529 things horribly.
530 * ser-e7kpc.c: Get rid of the DLL's since we can access the device
531 directly from Win32s and Win95. Get rid of debugify crud.

533 * (serial_logchar serial_log_command serial_write serial_readchar
534 serial_send_break serial_close): Merge common functionality into
535 serial_logchar. Clean up rest of routines.
536 * sparclet-rom.c: Disembowel. Leave only download routine.
537 Download routine now switches to remote target automatically.
538 * top.c (disconnect): Only define if SIGHUP is defined. Cleans
539 up MSVC/Win32 problem.
540 * utils.c (gdb_flush): Don't call hook unless it's for gdb_stdout
541 or gdb_stderr.
542 * config/sh/tm-sh.h: Define TARGET_SH for WinGDB.
543 * config/sparc/tm-sparclet.h: Remove override for prompt.

553 fields of gdb_callback.
554 (gdbsim_stop): Add gdbsim_stop to list of supported client
555 operations.
556 (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
557 sim_wait where gdb is in a position to handle a long running
558 function.
559 (gdbsim_cntrl_c): New function. Wrap the sim_resume call in a
560 SIGINT handler.
561 (gdb_os_poll_quit): New function. Check for a quit pending on the
562 console.

600 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
601 (INSTALL_XFORM1): Remove.
602 (install-only): Use $(program_transform_name) directly, rather
603 than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
604 (uninstall): Transform name.

620 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
621
622 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
623 since gcc automatically includes it
624
625 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
626
627 * procfs.c: Substantial (but incomplete) changes to support
628 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
629 struct now has substructs like struct flt_ctl instead of
630 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
631 map_fd instead of a single fd. Non-sysv4.2mp procfs models
632 still have the structs and multiple fds, but don't use the
633 entire struct and the four fds all point to the same thing.
634 We use PROCFS_USE_READ_WRITE to decide whether to talk to
635 procfs with reads/writes or use ioctl instead. We use
636 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
637 multiple fds or not. PROC_NAME_FMT is split out into
638 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
639 STATUS_PROC_NAME_FMT.
640
641 (procfs_notice_signals): now a necessary wrapper around
642 (notice_signals): which are the new guts for noticing signals
643 (open_proc_file): gets a new flag arg used in sysv4.2mp to
644 determine whether or not to attempt to open the ctl_fd.
645 (procfs_read_status): new local function, reads procfs status
646 (procfs_write_pcwstop): new local function, writes a PCWSTOP
647 (procfs_write_pckill): new local function, writes a PCKILL
648 (unconditionally_kill_inferior): remove signo since we now
649 just call procfs_write_pckill().
650 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
651 (proc_iterate_over_mappings): the whole function is ifdefed
652 on UNIXWARE to keep things readable.
653
654 Expanded the syscall_table to include new potential sysv4.2mp
655 members. Note that all ifdefs of UNIXWARE should be eliminated
656 if possible or renamed to describe what's being selected for a
657 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
658 IRIX specific code now also checks it's not UNIXWARE.
659
660 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
661 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
662 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
663 "/debug/%d" as PROC_NAME_FMT used to be
664
665 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
666
667 * mn10300-tdep.c: Almost completely rewritten based on mn10200
668 port.
669 * config/mn10300/tm-mn10300.h: Likewise.
670
671 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
672
673 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
674 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
675 lousy out-of-date clone of remote.c.
676
677 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
678
679 * remote.c: Fix problems realized while showering.
680 * (hexnumlen): Add prototype. Use max, not min.
681 * (remote_write_bytes remote_read_bytes): Fix max packet size
682 calculations to properly account for packet overhead. Also handle
683 (probably rare) case where remote_register_buf_size isn't set.
684
685 * remote.c: Fix doc for `C' and `S' commands to indicate full
686 address.
687 * (remote_ops extended_remote_ops remote_desc remote_write_size):
688 Make static.
689 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
690 Record size of response to fetch registers command, use this to
691 limit size of memory read and write commands.
692 * (push_remote_target): New function to make it possible to have
693 another target switch to the remote target.
694 * target.h: Add prototype for push_remote_target.
695 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
696 for hosts which default to unsigned chars (such as SGI's).
697 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
698 handled automatically in remote.c.
699
700 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
701
702 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
703 find_pc_sect_function(), find_pc_sect_partial_function(): new
704 functions for debugging overlays; pc without section is ambiguous.
705 * breakpoint.[ch]: add section pointer to breakpoint struct;
706 add section argument to check_duplicates(); check section as well
707 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
708 breakpoint_thread_match(), bpstat_stop_status()];
709 add section argument to describe_other_breakpoints();
710 use INIT_SAL() macro to zero-out new sal structures;
711 make resolve_sal_pc() fix up the sal's section as well as its pc;
712 match on section + pc in clear_command() and delete_breakpoint();
713 account for overlay sections in insert_breakpoints(),
714 remove_breakpoint() and breakpoint_re_set_one();
715 all this to support overlays where a PC is not unique.
716 * exec.c: change xfer_memory() to handle overlay sections.
717 * findvar.c: change read_var_value() to handle overlay sections.
718 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
719 * infcmd.c: jump_command() warns against jumping into an overlay
720 that's not in memory. Also use INIT_SAL() to initialize sals.
721 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
722 overlay state information; Also use INIT_SAL() to init sals.
723 * m32r-rom.c: modify load routines to use LMA instead of VMA.
724 * m32r-stub.c: mask exit value down to 8 bits; screen out any
725 memory read/writes in the range 600000 to a00000, and ff680000
726 to ff800000 (hangs because nothing is mapped there); fix strcpy().
727 * maint.c: maintenance command "translate-address" supports overlays.
728 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
729 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
730 this constitutes gdb's internal overlay mapping table. Add macro
731 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
732 Add function find_pc_sect_section().
733 * printcmd.c: modify print_address_symbolic() with overlay smarts;
734 modify address_info() with overlay smarts; add function sym_info()
735 to support the INFO SYMBOL command (translate address to symbol(s));
736 modify disassemble_command() to work on unmapped overlays.
737 * source.c: use INIT_SAL() to initialize sals.
738 * symfile.[ch]: change generic_load() to use section's LMA address
739 instead of VMA address, for overlay sections.
740 Add numerous functions for finding a PC's section / overlay,
741 translating between VMA and LMA address ranges, determining if an
742 overlay section is mapped, etc. Add several user commands for
743 overlay debugging. Add support for a "generic" form of automatically
744 reading overlay mapping info from the inferior (based on the default
745 (simple) overlay manager which Cygnus provides as an example).
746 * symtab.[ch]: add functions find_pc_sect_symtab(),
747 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
748 for lookup; modify lookup_symbol and decode_line_1() to use them;
749 modify find_function_start_sal() to account for overlay sections;
750 add macro INIT_SAL() for initializing struct symtab_and_line.
751 * target.c: fix a comment in the declaration of target_ops.
752
753 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
