  11
  12         * serial.c (serial_log_command):  Fix fputs_unfiltered calls.
  13
  14         * config/powerpc/tm-ppc-aix4.h, config/rs6000/tm-rs6000-aix4.h

  19         tstart and dstart with section VMA.
  20         * rs6000-nat.c (vmap_symtab):  Relocate relative to the VMA in the
  21         object file.
  22         (vmap_ldinfo, xcoff_relocate_core):  Adjust tstart by section offset
  23         of the text section, remove DONT_RELOCATE_SYMFILE_OBJFILE hack.
  24         (vmap_exec):  Relocate relative to the VMA in the object file,
  25         relocate .bss section as well.
  26         (xcoff_relocate_core):  No longer adjust section addresses by VMA.
  27         * rs6000-tdep.c (find_toc_address):  Change type of tocbase
  28         to CORE_ADDR.
  29         * xcoffread.c (secnum_to_bfd_section):  New routine to get
  30         BFD section from CS section number.
  31         (scan_xcoff_symtab):  Make toc_offset section relative.
  32
  33         * symtab.c (total_number_of_methods):  Avoid core dump if

  35
  36 Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)
  37
  38         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
  39         that directory.
  40         * defs.h utils.c (error warning):  Make message be const.
  41         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
  42         to hook.  Otherwise send it to fputs.
  43         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
  44         the obvious.
  45         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
  46         to _filtered forms to make output appear in GUIs.  Replace all
  47         uses of SERIAL_READCHAR with readchar, which has better error
  48         checking.
  49         * (e7000_parse_device):  Add prototype.
  50         (readchar):  Improve doc.  Handle random serial errors.
  51         (expect):  Disable notice_quit code.  It's busted.  Remove
  52         serial error handling (it's now handled in readchar).  Remove
  53         remote_debug echoing.  That's handled in readchar as well.
  54         (e7000_parse_device):  Remove serial_flag arg.  It's not
  55         necessary.
  56         (e7000_open):  Split into two pieces.  Second part is
  57         e7000_start_remote, and is error protected.  Now, when we connect
  58         to the target, we setup the initial frame and registers so that
  59         the user gets an immediate indication of where the target is.
  60         (gch):  Remove debug output.  That's handled by readchar.
  61         (e7000_read_inferior_memory):  Handle errors better.
  62         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
  63         command names.  They show up when doing completion and confuse
  64         things horribly.
  65         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
  66         directly from Win32s and Win95.  Get rid of debugify crud.
  67         * serial.c:  Remove debugify cruft.
  68         * (serial_logchar serial_log_command serial_write serial_readchar
  69         serial_send_break serial_close):  Merge common functionality into
  70         serial_logchar.  Clean up rest of routines.
  71         * sparclet-rom.c:  Disembowel.  Leave only download routine.
  72         Download routine now switches to remote target automatically.
  73         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
  74         up MSVC/Win32 problem.
  75         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
  76         or gdb_stderr.
  77         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
  78         * config/sparc/tm-sparclet.h:  Remove override for prompt.
  79
  80 Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>
  81
  82         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
  83         TARGET_BYTE ORDER_SELECTABLE.
  84
  85 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>
  86
  87         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
  88         fields of gdb_callback.
  89         (gdbsim_stop): Add gdbsim_stop to list of supported client
  90         operations.
  91         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
  92         sim_wait where gdb is in a position to handle a long running
  93         function.
  94         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
  95         SIGINT handler.
  96         (gdb_os_poll_quit): New function. Check for a quit pending on the
  97         console.
  98
  99 start-sanitize-gdbtk
 100 Wed Apr 16 12:33:06 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 101
 102         * Makefile.in (install-only): Make list of gdbtcl files to install
 103         explicit - was picking up files such as ChangeLog etc.
 104         (install-only): Don't blindly create the directory.
 105
 106 end-sanitize-gdbtk
 107 Thu Apr 17 14:30:04 1997  Per Bothner  <bothner@deneb.cygnus.com>
 108
 109         * defs.h (enum language):  Add language_java.
 110         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 111         * Makefile.in:  Update for new files.
 112         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
 113         * symfile.c (deduce_language_from_filename):  Recognize .java.
 114
 115 Thu Apr 17 02:20:23 1997  Doug Evans  <dje@canuck.cygnus.com>
 116
 117         * m32r-stub.c (stash_registers): Rewrite.
 118         (restore_registers): Renamed to restore_and_return.
 119         (cleanup_stash): New function.

 127
 128 Tue Apr 15 15:31:09 1997  Stan Shebs  <shebs@andros.cygnus.com>
 129
 130         * remote.c (get_offsets): Don't use scanf for interpreting
 131         response to qOffsets.
 132
 133 Tue Apr 15 14:51:04 1997  Ian Lance Taylor  <ian@cygnus.com>
 134
 135         * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
 136         (INSTALL_XFORM1): Remove.
 137         (install-only): Use $(program_transform_name) directly, rather
 138         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 139         (uninstall): Transform name.
 140
 141 Mon Apr 14 17:06:27 1997  Mark Alexander  <marka@cygnus.com>
 142
 143         * remote-mips.c (mips_load): Ensure that PC gets updated
 144         after a load on LSI target.
 145
 146 Mon Apr 14 15:54:51 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 147
 148         * procfs.c (notice_signals): fix typo
 149
 150 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>
 151
 152         * gdbserver/Makefile.in (INSTALL): Change install.sh to
 153         install-sh.
 154
 155 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 156
 157         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 158         since gcc automatically includes it
 159
 160 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 161
 162         * procfs.c: Substantial (but incomplete) changes to support
 163         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 164         struct now has substructs like struct flt_ctl instead of
 165         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 166         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 167         still have the structs and multiple fds, but don't use the
 168         entire struct and the four fds all point to the same thing.
 169         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 170         procfs with reads/writes or use ioctl instead.  We use
 171         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 172         multiple fds or not.  PROC_NAME_FMT is split out into
 173         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 174         STATUS_PROC_NAME_FMT.
 175
 176         (procfs_notice_signals): now a necessary wrapper around
 177         (notice_signals): which are the new guts for noticing signals
 178         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 179         determine whether or not to attempt to open the ctl_fd.
 180         (procfs_read_status): new local function, reads procfs status
 181         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 182         (procfs_write_pckill): new local function, writes a PCKILL
 183         (unconditionally_kill_inferior): remove signo since we now
 184         just call procfs_write_pckill().
 185         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 186         (proc_iterate_over_mappings): the whole function is ifdefed
 187         on UNIXWARE to keep things readable.
 188
 189         Expanded the syscall_table to include new potential sysv4.2mp
 190         members.  Note that all ifdefs of UNIXWARE should be eliminated
 191         if possible or renamed to describe what's being selected for a
 192         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 193         IRIX specific code now also checks it's not UNIXWARE.
 194
 195         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 196         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 197         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 198         "/debug/%d" as PROC_NAME_FMT used to be
 199
 200 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 201
 202         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 203         port.
 204         * config/mn10300/tm-mn10300.h: Likewise.
 205
 206 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 207
 208         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 209         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 210         lousy out-of-date clone of remote.c.
 211
 212 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 213
 214         * remote.c:  Fix problems realized while showering.
 215         * (hexnumlen):  Add prototype.  Use max, not min.
 216         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 217         calculations to properly account for packet overhead.  Also handle
 218         (probably rare) case where remote_register_buf_size isn't set.
 219
 220         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 221         address.
 222         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 223         Make static.
 224         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 225         Record size of response to fetch registers command, use this to
 226         limit size of memory read and write commands.
 227         * (push_remote_target):  New function to make it possible to have
 228         another target switch to the remote target.
 229         * target.h:  Add prototype for push_remote_target.
 230         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 231         for hosts which default to unsigned chars (such as SGI's).
 232         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 233         handled automatically in remote.c.
 234
 235 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 236
 237         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 238         find_pc_sect_function(), find_pc_sect_partial_function(): new
 239         functions for debugging overlays; pc without section is ambiguous.
 240         * breakpoint.[ch]: add section pointer to breakpoint struct;
 241         add section argument to check_duplicates(); check section as well
 242         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 243         breakpoint_thread_match(), bpstat_stop_status()];
 244         add section argument to describe_other_breakpoints();
 245         use INIT_SAL() macro to zero-out new sal structures;
 246         make resolve_sal_pc() fix up the sal's section as well as its pc;
 247         match on section + pc in clear_command() and delete_breakpoint();
 248         account for overlay sections in insert_breakpoints(),
 249         remove_breakpoint() and breakpoint_re_set_one();
 250         all this to support overlays where a PC is not unique.
 251         * exec.c: change xfer_memory() to handle overlay sections.
 252         * findvar.c: change read_var_value() to handle overlay sections.
 253         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 254         * infcmd.c: jump_command() warns against jumping into an overlay
 255         that's not in memory.  Also use INIT_SAL() to initialize sals.
 256         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 257         overlay state information; Also use INIT_SAL() to init sals.
 258         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 259         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 260         memory read/writes in the range 600000 to a00000, and ff680000
 261         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 262         * maint.c: maintenance command "translate-address" supports overlays.
 263         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 264         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 265         this constitutes gdb's internal overlay mapping table.  Add macro
 266         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 267         Add function find_pc_sect_section().
 268         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 269         modify address_info() with overlay smarts; add function sym_info()
 270         to support the INFO SYMBOL command (translate address to symbol(s));
 271         modify disassemble_command() to work on unmapped overlays.
 272         * source.c: use INIT_SAL() to initialize sals.
 273         * symfile.[ch]: change generic_load() to use section's LMA address
 274         instead of VMA address, for overlay sections.
 275         Add numerous functions for finding a PC's section / overlay,
 276         translating between VMA and LMA address ranges, determining if an
 277         overlay section is mapped, etc.  Add several user commands for
 278         overlay debugging.  Add support for a "generic" form of automatically
 279         reading overlay mapping info from the inferior (based on the default
 280         (simple) overlay manager which Cygnus provides as an example).
 281         * symtab.[ch]: add functions find_pc_sect_symtab(),
 282         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 283         for lookup; modify lookup_symbol and decode_line_1() to use them;
 284         modify find_function_start_sal() to account for overlay sections;
 285         add macro INIT_SAL() for initializing struct symtab_and_line.
 286         * target.c: fix a comment in the declaration of target_ops.
 287
 288 Thu Apr  3 10:31:12 1997  Mark Alexander  <marka@cygnus.com>
 289

 291         mips_skip_stub, mips_ignore_helper): New functions for dealing
 292         with MIPS16 call/return thunks.
 293         (mips_init_frame_pc_first): New function to implement
 294         INIT_FRAME_PC_FIRST macro; includes code from old macro plus
 295         new code to skip over MIPS16 thunks.
 296         (mips_frame_chain): Skip over MIPS16 thunks.
 297         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
 298         mips_skip_stub, mips_ignore_helper): Declare.
 299         (IN_SOLIB_CALL_TRAMPOLINE, IN_SOLIB_RETURN_TRAMPOLINE,
 300         SKIP_TRAMPOLINE_CODE, IGNORE_HELPER_CALL): New macros that invoke
 301         the above functions.
 302         (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
 303         (mips_init_frame_pc): Declare.
 304         * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
 305         to decide if certain library function calls should be ignored.
 306
 307 Wed Apr  2 14:16:51 1997  Doug Evans  <dje@canuck.cygnus.com>
 308
 309         * remote-sim.c (gdbsim_open): Check return code from sim_open.
 310         Update call to sim_open (new arg SIM_OPEN_DEBUG).

1140         ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
1141         arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
