  37
  38         * serial.c (serial_log_command):  Fix fputs_unfiltered calls.

  45         tstart and dstart with section VMA.
  46         * rs6000-nat.c (vmap_symtab):  Relocate relative to the VMA in the
  47         object file.
  48         (vmap_ldinfo, xcoff_relocate_core):  Adjust tstart by section offset
  49         of the text section, remove DONT_RELOCATE_SYMFILE_OBJFILE hack.
  50         (vmap_exec):  Relocate relative to the VMA in the object file,
  51         relocate .bss section as well.
  52         (xcoff_relocate_core):  No longer adjust section addresses by VMA.
  53         * rs6000-tdep.c (find_toc_address):  Change type of tocbase
  54         to CORE_ADDR.
  55         * xcoffread.c (secnum_to_bfd_section):  New routine to get
  56         BFD section from CS section number.
  57         (scan_xcoff_symtab):  Make toc_offset section relative.
  58
  59         * symtab.c (total_number_of_methods):  Avoid core dump if

  61
  62 Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)
  63
  64         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
  65         that directory.
  66         * defs.h utils.c (error warning):  Make message be const.
  67         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
  68         to hook.  Otherwise send it to fputs.
  69         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
  70         the obvious.
  71         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
  72         to _filtered forms to make output appear in GUIs.  Replace all
  73         uses of SERIAL_READCHAR with readchar, which has better error
  74         checking.
  75         * (e7000_parse_device):  Add prototype.
  76         (readchar):  Improve doc.  Handle random serial errors.
  77         (expect):  Disable notice_quit code.  It's busted.  Remove
  78         serial error handling (it's now handled in readchar).  Remove
  79         remote_debug echoing.  That's handled in readchar as well.
  80         (e7000_parse_device):  Remove serial_flag arg.  It's not
  81         necessary.
  82         (e7000_open):  Split into two pieces.  Second part is
  83         e7000_start_remote, and is error protected.  Now, when we connect
  84         to the target, we setup the initial frame and registers so that
  85         the user gets an immediate indication of where the target is.
  86         (gch):  Remove debug output.  That's handled by readchar.
  87         (e7000_read_inferior_memory):  Handle errors better.
  88         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
  89         command names.  They show up when doing completion and confuse
  90         things horribly.
  91         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
  92         directly from Win32s and Win95.  Get rid of debugify crud.
  93         * serial.c:  Remove debugify cruft.
  94         * (serial_logchar serial_log_command serial_write serial_readchar
  95         serial_send_break serial_close):  Merge common functionality into
  96         serial_logchar.  Clean up rest of routines.
  97         * sparclet-rom.c:  Disembowel.  Leave only download routine.
  98         Download routine now switches to remote target automatically.
  99         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 100         up MSVC/Win32 problem.
 101         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
 102         or gdb_stderr.
 103         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
 104         * config/sparc/tm-sparclet.h:  Remove override for prompt.

 106 Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>
 107
 108         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
 109         TARGET_BYTE ORDER_SELECTABLE.
 110
 111 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 112
 113         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
 114         fields of gdb_callback.
 115         (gdbsim_stop): Add gdbsim_stop to list of supported client
 116         operations.
 117         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 118         sim_wait where gdb is in a position to handle a long running
 119         function.
 120         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 121         SIGINT handler.
 122         (gdb_os_poll_quit): New function. Check for a quit pending on the
 123         console.

 126 Wed Apr 16 12:33:06 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 127
 128         * Makefile.in (install-only): Make list of gdbtcl files to install
 129         explicit - was picking up files such as ChangeLog etc.
 130         (install-only): Don't blindly create the directory.

 133 Thu Apr 17 14:30:04 1997  Per Bothner  <bothner@deneb.cygnus.com>
 134
 135         * defs.h (enum language):  Add language_java.
 136         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 137         * Makefile.in:  Update for new files.
 138         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
 139         * symfile.c (deduce_language_from_filename):  Recognize .java.

 141 Thu Apr 17 02:20:23 1997  Doug Evans  <dje@canuck.cygnus.com>
 142
 143         * m32r-stub.c (stash_registers): Rewrite.
 144         (restore_registers): Renamed to restore_and_return.
 145         (cleanup_stash): New function.

 148
 149         * remote-sim.c (gdbsim_load): Update call to sim_load.
 150         (gdbsim_create_inferior): No longer pass start_address to
 151         sim_create_inferior.
 152         (gdbsim_open): Pass endian indicator as arg.
 153
 154 Tue Apr 15 15:31:09 1997  Stan Shebs  <shebs@andros.cygnus.com>
 155
 156         * remote.c (get_offsets): Don't use scanf for interpreting
 157         response to qOffsets.
 158
 159 Tue Apr 15 14:51:04 1997  Ian Lance Taylor  <ian@cygnus.com>
 160

 162         (INSTALL_XFORM1): Remove.
 163         (install-only): Use $(program_transform_name) directly, rather
 164         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 165         (uninstall): Transform name.
 166
 167 Mon Apr 14 17:06:27 1997  Mark Alexander  <marka@cygnus.com>
 168
 169         * remote-mips.c (mips_load): Ensure that PC gets updated
 170         after a load on LSI target.
 171
 172 Mon Apr 14 15:54:51 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 173
 174         * procfs.c (notice_signals): fix typo
 175
 176 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>
 177
 178         * gdbserver/Makefile.in (INSTALL): Change install.sh to
 179         install-sh.
 180
 181 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 182
 183         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 184         since gcc automatically includes it
 185
 186 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 187
 188         * procfs.c: Substantial (but incomplete) changes to support
 189         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 190         struct now has substructs like struct flt_ctl instead of
 191         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 192         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 193         still have the structs and multiple fds, but don't use the
 194         entire struct and the four fds all point to the same thing.
 195         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 196         procfs with reads/writes or use ioctl instead.  We use
 197         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 198         multiple fds or not.  PROC_NAME_FMT is split out into
 199         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 200         STATUS_PROC_NAME_FMT.
 201
 202         (procfs_notice_signals): now a necessary wrapper around
 203         (notice_signals): which are the new guts for noticing signals
 204         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 205         determine whether or not to attempt to open the ctl_fd.
 206         (procfs_read_status): new local function, reads procfs status
 207         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 208         (procfs_write_pckill): new local function, writes a PCKILL
 209         (unconditionally_kill_inferior): remove signo since we now
 210         just call procfs_write_pckill().
 211         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 212         (proc_iterate_over_mappings): the whole function is ifdefed
 213         on UNIXWARE to keep things readable.
 214
 215         Expanded the syscall_table to include new potential sysv4.2mp
 216         members.  Note that all ifdefs of UNIXWARE should be eliminated
 217         if possible or renamed to describe what's being selected for a
 218         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 219         IRIX specific code now also checks it's not UNIXWARE.
 220
 221         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 222         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 223         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 224         "/debug/%d" as PROC_NAME_FMT used to be
 225
 226 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 227
 228         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 229         port.
 230         * config/mn10300/tm-mn10300.h: Likewise.
 231
 232 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 233
 234         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 235         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 236         lousy out-of-date clone of remote.c.
 237
 238 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 239
 240         * remote.c:  Fix problems realized while showering.
 241         * (hexnumlen):  Add prototype.  Use max, not min.
 242         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 243         calculations to properly account for packet overhead.  Also handle
 244         (probably rare) case where remote_register_buf_size isn't set.
 245
 246         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 247         address.
 248         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 249         Make static.
 250         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 251         Record size of response to fetch registers command, use this to
 252         limit size of memory read and write commands.
 253         * (push_remote_target):  New function to make it possible to have
 254         another target switch to the remote target.
 255         * target.h:  Add prototype for push_remote_target.
 256         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 257         for hosts which default to unsigned chars (such as SGI's).
 258         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 259         handled automatically in remote.c.
 260
 261 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 262
 263         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 264         find_pc_sect_function(), find_pc_sect_partial_function(): new
 265         functions for debugging overlays; pc without section is ambiguous.
 266         * breakpoint.[ch]: add section pointer to breakpoint struct;
 267         add section argument to check_duplicates(); check section as well
 268         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 269         breakpoint_thread_match(), bpstat_stop_status()];
 270         add section argument to describe_other_breakpoints();
 271         use INIT_SAL() macro to zero-out new sal structures;
 272         make resolve_sal_pc() fix up the sal's section as well as its pc;
 273         match on section + pc in clear_command() and delete_breakpoint();
 274         account for overlay sections in insert_breakpoints(),
 275         remove_breakpoint() and breakpoint_re_set_one();
 276         all this to support overlays where a PC is not unique.
 277         * exec.c: change xfer_memory() to handle overlay sections.
 278         * findvar.c: change read_var_value() to handle overlay sections.
 279         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 280         * infcmd.c: jump_command() warns against jumping into an overlay
 281         that's not in memory.  Also use INIT_SAL() to initialize sals.
 282         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 283         overlay state information; Also use INIT_SAL() to init sals.
 284         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 285         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 286         memory read/writes in the range 600000 to a00000, and ff680000
 287         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 288         * maint.c: maintenance command "translate-address" supports overlays.
 289         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 290         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 291         this constitutes gdb's internal overlay mapping table.  Add macro
 292         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 293         Add function find_pc_sect_section().
 294         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 295         modify address_info() with overlay smarts; add function sym_info()
 296         to support the INFO SYMBOL command (translate address to symbol(s));
 297         modify disassemble_command() to work on unmapped overlays.
 298         * source.c: use INIT_SAL() to initialize sals.
 299         * symfile.[ch]: change generic_load() to use section's LMA address
 300         instead of VMA address, for overlay sections.
 301         Add numerous functions for finding a PC's section / overlay,
 302         translating between VMA and LMA address ranges, determining if an
 303         overlay section is mapped, etc.  Add several user commands for
 304         overlay debugging.  Add support for a "generic" form of automatically
 305         reading overlay mapping info from the inferior (based on the default
 306         (simple) overlay manager which Cygnus provides as an example).
 307         * symtab.[ch]: add functions find_pc_sect_symtab(),
 308         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 309         for lookup; modify lookup_symbol and decode_line_1() to use them;
 310         modify find_function_start_sal() to account for overlay sections;
 311         add macro INIT_SAL() for initializing struct symtab_and_line.
 312         * target.c: fix a comment in the declaration of target_ops.
 313
 314 Thu Apr  3 10:31:12 1997  Mark Alexander  <marka@cygnus.com>
