  13
  14         * Makefile.in: Add rule for gnu-nat.o and i386gnu-nat.o (Gnu Hurd)
  15         * config/i386/i386gnu.mh: remove rules for [i386]gnu-nat.o, now
  16         in Makefile.in (as for other targets); add NATDEPFILE corelow.o to
  17         satisfy symbol dependancy in solib.c (core_ops).
  18         * target.[ch] conditionalize Mach-specific signals so that they
  19         won't show up in non-Mach gdb's!
  20         * thread.c: add function thread_id_to_pid; change name of static
  21         function "thread_switch" to "switch_to_thread", to avoid conflict
  22         with Mach global symbol; move thread_cmd_list to global scope
  23         so targets can add their own thread commands.
  24         * infrun.c: sig_print_info: allow for long signal names.
  25         * gnu-nat.[ch]: tidying up comments.
  26         * gnu-nat.c: move several functions to static scope, just for tidy;
  27         remove calls to prune_threads and renumber_threads;
  28         gnu_wait must not return -1 when inferior exits;
  29         attach_to_child will modify inferior_pid in a way that allows
  30         fork_inferior to remain unchanged;
  31         remove extra arg from startup_inferior;
  32         move mach-specific thread commands here from thread.c.

  36         * symtab.c: decode_line_1, replace the assignment to
  37         values.sals[0].pc which I accidentally left out on 4/3/97.

  44         of help strings.
  45

  55         for return address register, handle `ret' instruction.
  56
  57         * corelow.c (get_core_registers):  Initialize cf.
  58
  59         * procfs.c:  Minor changes to make pre-ANSI compilers happy.

  61         pi->prrun.pr_trace.
  62         (unconditionally_kill_inferior):  If PR_DEAD is defined,
  63         rerun inferior after killing it.

  68         structure value address is found in $a0 now.
  69         * config/mn10200/tm-mn10200.h (EXTRACT_STRUCT_VALUE_ADDRESS): Likewise.

 170 Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)
 171
 172         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
 173         that directory.
 174         * defs.h utils.c (error warning):  Make message be const.
 175         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
 176         to hook.  Otherwise send it to fputs.
 177         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
 178         the obvious.
 179         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
 180         to _filtered forms to make output appear in GUIs.  Replace all
 181         uses of SERIAL_READCHAR with readchar, which has better error
 182         checking.
 183         * (e7000_parse_device):  Add prototype.
 184         (readchar):  Improve doc.  Handle random serial errors.
 185         (expect):  Disable notice_quit code.  It's busted.  Remove
 186         serial error handling (it's now handled in readchar).  Remove
 187         remote_debug echoing.  That's handled in readchar as well.

 189         necessary.
 190         (e7000_open):  Split into two pieces.  Second part is
 191         e7000_start_remote, and is error protected.  Now, when we connect
 192         to the target, we setup the initial frame and registers so that
 193         the user gets an immediate indication of where the target is.
 194         (gch):  Remove debug output.  That's handled by readchar.
 195         (e7000_read_inferior_memory):  Handle errors better.
 196         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
 197         command names.  They show up when doing completion and confuse
 198         things horribly.
 199         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
 200         directly from Win32s and Win95.  Get rid of debugify crud.
 201         * serial.c:  Remove debugify cruft.
 202         * (serial_logchar serial_log_command serial_write serial_readchar
 203         serial_send_break serial_close):  Merge common functionality into
 204         serial_logchar.  Clean up rest of routines.
 205         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 206         Download routine now switches to remote target automatically.
 207         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 208         up MSVC/Win32 problem.
 209         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
 210         or gdb_stderr.
 211         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
 212         * config/sparc/tm-sparclet.h:  Remove override for prompt.

 216         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
 217         TARGET_BYTE ORDER_SELECTABLE.
 218
 219 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>

 222         fields of gdb_callback.
 223         (gdbsim_stop): Add gdbsim_stop to list of supported client
 224         operations.
 225         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 226         sim_wait where gdb is in a position to handle a long running
 227         function.
 228         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 229         SIGINT handler.
 230         (gdb_os_poll_quit): New function. Check for a quit pending on the
 231         console.

 237         explicit - was picking up files such as ChangeLog etc.
 238         (install-only): Don't blindly create the directory.

 244         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 245         * Makefile.in:  Update for new files.
 246         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.

 270         (INSTALL_XFORM1): Remove.
 271         (install-only): Use $(program_transform_name) directly, rather
 272         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 273         (uninstall): Transform name.

 289 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 290
 291         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 292         since gcc automatically includes it
 293
 294 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 295
 296         * procfs.c: Substantial (but incomplete) changes to support
 297         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 298         struct now has substructs like struct flt_ctl instead of
 299         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 300         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 301         still have the structs and multiple fds, but don't use the
 302         entire struct and the four fds all point to the same thing.
 303         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 304         procfs with reads/writes or use ioctl instead.  We use
 305         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 306         multiple fds or not.  PROC_NAME_FMT is split out into
 307         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 308         STATUS_PROC_NAME_FMT.
 309
 310         (procfs_notice_signals): now a necessary wrapper around
 311         (notice_signals): which are the new guts for noticing signals
 312         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 313         determine whether or not to attempt to open the ctl_fd.
 314         (procfs_read_status): new local function, reads procfs status
 315         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 316         (procfs_write_pckill): new local function, writes a PCKILL
 317         (unconditionally_kill_inferior): remove signo since we now
 318         just call procfs_write_pckill().
 319         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 320         (proc_iterate_over_mappings): the whole function is ifdefed
 321         on UNIXWARE to keep things readable.
 322
 323         Expanded the syscall_table to include new potential sysv4.2mp
 324         members.  Note that all ifdefs of UNIXWARE should be eliminated
 325         if possible or renamed to describe what's being selected for a
 326         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 327         IRIX specific code now also checks it's not UNIXWARE.

 374         * breakpoint.[ch]: add section pointer to breakpoint struct;
 375         add section argument to check_duplicates(); check section as well
 376         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 377         breakpoint_thread_match(), bpstat_stop_status()];
 378         add section argument to describe_other_breakpoints();
 379         use INIT_SAL() macro to zero-out new sal structures;
 380         make resolve_sal_pc() fix up the sal's section as well as its pc;
 381         match on section + pc in clear_command() and delete_breakpoint();
 382         account for overlay sections in insert_breakpoints(),
 383         remove_breakpoint() and breakpoint_re_set_one();
 384         all this to support overlays where a PC is not unique.
 385         * exec.c: change xfer_memory() to handle overlay sections.
 386         * findvar.c: change read_var_value() to handle overlay sections.
 387         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 388         * infcmd.c: jump_command() warns against jumping into an overlay
 389         that's not in memory.  Also use INIT_SAL() to initialize sals.
 390         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 391         overlay state information; Also use INIT_SAL() to init sals.

 393         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 394         memory read/writes in the range 600000 to a00000, and ff680000
 395         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 396         * maint.c: maintenance command "translate-address" supports overlays.
 397         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 398         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 399         this constitutes gdb's internal overlay mapping table.  Add macro
 400         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 401         Add function find_pc_sect_section().
 402         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 403         modify address_info() with overlay smarts; add function sym_info()
 404         to support the INFO SYMBOL command (translate address to symbol(s));
 405         modify disassemble_command() to work on unmapped overlays.
 406         * source.c: use INIT_SAL() to initialize sals.
 407         * symfile.[ch]: change generic_load() to use section's LMA address
 408         instead of VMA address, for overlay sections.
 409         Add numerous functions for finding a PC's section / overlay,
 410         translating between VMA and LMA address ranges, determining if an
 411         overlay section is mapped, etc.  Add several user commands for
 412         overlay debugging.  Add support for a "generic" form of automatically
 413         reading overlay mapping info from the inferior (based on the default
 414         (simple) overlay manager which Cygnus provides as an example).
 415         * symtab.[ch]: add functions find_pc_sect_symtab(),
 416         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 417         for lookup; modify lookup_symbol and decode_line_1() to use them;
 418         modify find_function_start_sal() to account for overlay sections;
 419         add macro INIT_SAL() for initializing struct symtab_and_line.
 420         * target.c: fix a comment in the declaration of target_ops.
