   8
   9         * Makefile.in: Add rule for gnu-nat.o and i386gnu-nat.o (Gnu Hurd)
  10         * config/i386/i386gnu.mh: remove rules for [i386]gnu-nat.o, now
  11         in Makefile.in (as for other targets); add NATDEPFILE corelow.o to
  12         satisfy symbol dependancy in solib.c (core_ops).
  13         * target.[ch] conditionalize Mach-specific signals so that they
  14         won't show up in non-Mach gdb's!
  15         * thread.c: add function thread_id_to_pid; change name of static
  16         function "thread_switch" to "switch_to_thread", to avoid conflict
  17         with Mach global symbol; move thread_cmd_list to global scope
  18         so targets can add their own thread commands.
  19         * infrun.c: sig_print_info: allow for long signal names.
  20         * gnu-nat.[ch]: tidying up comments.
  21         * gnu-nat.c: move several functions to static scope, just for tidy;
  22         remove calls to prune_threads and renumber_threads;
  23         gnu_wait must not return -1 when inferior exits;
  24         attach_to_child will modify inferior_pid in a way that allows
  25         fork_inferior to remain unchanged;
  26         remove extra arg from startup_inferior;
  27         move mach-specific thread commands here from thread.c.

  37         (fix by Bob Manson).
  38         * top.c: change "to enable to enable" to "to enable" in a couple
  39         of help strings.

  51
  52         * corelow.c (get_core_registers):  Initialize cf.
  53
  54         * procfs.c:  Minor changes to make pre-ANSI compilers happy.

  56         pi->prrun.pr_trace.
  57         (unconditionally_kill_inferior):  If PR_DEAD is defined,
  58         rerun inferior after killing it.

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

 165 Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)
 166
 167         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
 168         that directory.
 169         * defs.h utils.c (error warning):  Make message be const.
 170         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
 171         to hook.  Otherwise send it to fputs.
 172         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
 173         the obvious.
 174         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
 175         to _filtered forms to make output appear in GUIs.  Replace all
 176         uses of SERIAL_READCHAR with readchar, which has better error
 177         checking.
 178         * (e7000_parse_device):  Add prototype.
 179         (readchar):  Improve doc.  Handle random serial errors.
 180         (expect):  Disable notice_quit code.  It's busted.  Remove
 181         serial error handling (it's now handled in readchar).  Remove
 182         remote_debug echoing.  That's handled in readchar as well.

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

 209 Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>
 210
 211         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
 212         TARGET_BYTE ORDER_SELECTABLE.
 213
 214 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 215
 216         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
 217         fields of gdb_callback.
 218         (gdbsim_stop): Add gdbsim_stop to list of supported client
 219         operations.
 220         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 221         sim_wait where gdb is in a position to handle a long running
 222         function.
 223         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 224         SIGINT handler.
 225         (gdb_os_poll_quit): New function. Check for a quit pending on the
 226         console.

 229 Wed Apr 16 12:33:06 1997  Andrew Cagney  <cagney@b1.cygnus.com>

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

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

 265         (INSTALL_XFORM1): Remove.
 266         (install-only): Use $(program_transform_name) directly, rather
 267         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 268         (uninstall): Transform name.

 285
 286         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 287         since gcc automatically includes it
 288
 289 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 290
 291         * procfs.c: Substantial (but incomplete) changes to support
 292         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 293         struct now has substructs like struct flt_ctl instead of
 294         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 295         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 296         still have the structs and multiple fds, but don't use the
 297         entire struct and the four fds all point to the same thing.
 298         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 299         procfs with reads/writes or use ioctl instead.  We use
 300         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 301         multiple fds or not.  PROC_NAME_FMT is split out into
 302         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 303         STATUS_PROC_NAME_FMT.
 304
 305         (procfs_notice_signals): now a necessary wrapper around
 306         (notice_signals): which are the new guts for noticing signals
 307         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 308         determine whether or not to attempt to open the ctl_fd.
 309         (procfs_read_status): new local function, reads procfs status
 310         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 311         (procfs_write_pckill): new local function, writes a PCKILL
 312         (unconditionally_kill_inferior): remove signo since we now
 313         just call procfs_write_pckill().
 314         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 315         (proc_iterate_over_mappings): the whole function is ifdefed
 316         on UNIXWARE to keep things readable.
 317
 318         Expanded the syscall_table to include new potential sysv4.2mp
 319         members.  Note that all ifdefs of UNIXWARE should be eliminated
 320         if possible or renamed to describe what's being selected for a
 321         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 322         IRIX specific code now also checks it's not UNIXWARE.
 323
 324         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 325         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 326         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to

 338         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 339         lousy out-of-date clone of remote.c.

 367         find_pc_sect_function(), find_pc_sect_partial_function(): new

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

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