  45         * thread.c: change name of static function "thread_switch" to
  46         "switch_to_thread", to avoid conflict with Mach global symbol;
  47         move thread_cmd_list to global scope so targets can add their

  53         attach_to_child will modify inferior_pid in a way that allows
  54         fork_inferior to remain unchanged; remove extra arg from
  55         startup_inferior; move Mach thread commands here from thread.c.

 194
 195         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
 196         that directory.
 197         * defs.h utils.c (error warning):  Make message be const.
 198         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
 199         to hook.  Otherwise send it to fputs.
 200         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
 201         the obvious.
 202         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
 203         to _filtered forms to make output appear in GUIs.  Replace all

 207         (readchar):  Improve doc.  Handle random serial errors.

 212         necessary.
 213         (e7000_open):  Split into two pieces.  Second part is
 214         e7000_start_remote, and is error protected.  Now, when we connect
 215         to the target, we setup the initial frame and registers so that
 216         the user gets an immediate indication of where the target is.
 217         (gch):  Remove debug output.  That's handled by readchar.
 218         (e7000_read_inferior_memory):  Handle errors better.
 219         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
 220         command names.  They show up when doing completion and confuse
 221         things horribly.
 222         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
 223         directly from Win32s and Win95.  Get rid of debugify crud.
 224         * serial.c:  Remove debugify cruft.
 225         * (serial_logchar serial_log_command serial_write serial_readchar
 226         serial_send_break serial_close):  Merge common functionality into
 227         serial_logchar.  Clean up rest of routines.
 228         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 229         Download routine now switches to remote target automatically.
 230         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 231         up MSVC/Win32 problem.
 232         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
 233         or gdb_stderr.
 234         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
 235         * config/sparc/tm-sparclet.h:  Remove override for prompt.

 240         TARGET_BYTE ORDER_SELECTABLE.

 245         fields of gdb_callback.
 246         (gdbsim_stop): Add gdbsim_stop to list of supported client
 247         operations.
 248         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 249         sim_wait where gdb is in a position to handle a long running
 250         function.
 251         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 252         SIGINT handler.
 253         (gdb_os_poll_quit): New function. Check for a quit pending on the
 254         console.

 293         (INSTALL_XFORM1): Remove.
 294         (install-only): Use $(program_transform_name) directly, rather

 318
 319         * procfs.c: Substantial (but incomplete) changes to support
 320         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 321         struct now has substructs like struct flt_ctl instead of
 322         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 323         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 324         still have the structs and multiple fds, but don't use the
 325         entire struct and the four fds all point to the same thing.
 326         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 327         procfs with reads/writes or use ioctl instead.  We use
 328         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 329         multiple fds or not.  PROC_NAME_FMT is split out into
 330         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 331         STATUS_PROC_NAME_FMT.
 332
 333         (procfs_notice_signals): now a necessary wrapper around
 334         (notice_signals): which are the new guts for noticing signals
 335         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 336         determine whether or not to attempt to open the ctl_fd.
 337         (procfs_read_status): new local function, reads procfs status
 338         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 339         (procfs_write_pckill): new local function, writes a PCKILL
 340         (unconditionally_kill_inferior): remove signo since we now
 341         just call procfs_write_pckill().
 342         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 343         (proc_iterate_over_mappings): the whole function is ifdefed
 344         on UNIXWARE to keep things readable.
 345
 346         Expanded the syscall_table to include new potential sysv4.2mp
 347         members.  Note that all ifdefs of UNIXWARE should be eliminated
 348         if possible or renamed to describe what's being selected for a
 349         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 350         IRIX specific code now also checks it's not UNIXWARE.
 351
 352         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 353         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 354         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 355         "/debug/%d" as PROC_NAME_FMT used to be

 365         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 366         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 367         lousy out-of-date clone of remote.c.

 381         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 382         Record size of response to fetch registers command, use this to
 383         limit size of memory read and write commands.
 384         * (push_remote_target):  New function to make it possible to have
 385         another target switch to the remote target.
 386         * target.h:  Add prototype for push_remote_target.
 387         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 388         for hosts which default to unsigned chars (such as SGI's).
 389         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 390         handled automatically in remote.c.

 395         find_pc_sect_function(), find_pc_sect_partial_function(): new
 396         functions for debugging overlays; pc without section is ambiguous.
 397         * breakpoint.[ch]: add section pointer to breakpoint struct;
 398         add section argument to check_duplicates(); check section as well
 399         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 400         breakpoint_thread_match(), bpstat_stop_status()];
 401         add section argument to describe_other_breakpoints();
 402         use INIT_SAL() macro to zero-out new sal structures;
 403         make resolve_sal_pc() fix up the sal's section as well as its pc;
 404         match on section + pc in clear_command() and delete_breakpoint();
 405         account for overlay sections in insert_breakpoints(),
 406         remove_breakpoint() and breakpoint_re_set_one();
 407         all this to support overlays where a PC is not unique.
 408         * exec.c: change xfer_memory() to handle overlay sections.
 409         * findvar.c: change read_var_value() to handle overlay sections.
 410         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 411         * infcmd.c: jump_command() warns against jumping into an overlay
 412         that's not in memory.  Also use INIT_SAL() to initialize sals.
 413         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 414         overlay state information; Also use INIT_SAL() to init sals.
 415         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 416         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 417         memory read/writes in the range 600000 to a00000, and ff680000
 418         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 419         * maint.c: maintenance command "translate-address" supports overlays.
 420         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 421         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 422         this constitutes gdb's internal overlay mapping table.  Add macro
 423         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 424         Add function find_pc_sect_section().
 425         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 426         modify address_info() with overlay smarts; add function sym_info()
 427         to support the INFO SYMBOL command (translate address to symbol(s));
 428         modify disassemble_command() to work on unmapped overlays.
 429         * source.c: use INIT_SAL() to initialize sals.
 430         * symfile.[ch]: change generic_load() to use section's LMA address
 431         instead of VMA address, for overlay sections.
 432         Add numerous functions for finding a PC's section / overlay,
 433         translating between VMA and LMA address ranges, determining if an
 434         overlay section is mapped, etc.  Add several user commands for
 435         overlay debugging.  Add support for a "generic" form of automatically
 436         reading overlay mapping info from the inferior (based on the default
 437         (simple) overlay manager which Cygnus provides as an example).
 438         * symtab.[ch]: add functions find_pc_sect_symtab(),
 439         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 440         for lookup; modify lookup_symbol and decode_line_1() to use them;
 441         modify find_function_start_sal() to account for overlay sections;
 442         add macro INIT_SAL() for initializing struct symtab_and_line.
 443         * target.c: fix a comment in the declaration of target_ops.
