   6
   7         * java-exp.y:  Combine TRUE and FALSE into BOOLEAN_LITERAL.

  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
  15         (DONT_RELOCATE_SYMFILE_OBJFILE):  Removed.
  16         * xcoffsolib.h (struct vmap):  Add new members tvma, toffs and dvma,
  17         remove tadj.
  18         * exec.c (bfdsec_to_vmap):  Initialize new vmap members, initialize
  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
  34         baseclass type is still undefined.
  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:  Remove the last seven months of brain damage.  Get
  66         rid of the DLL's since we can access the device directly from Win32s
  67         and Win95.  Get rid of debugify crud.
  68         * serial.c:  Remove debugify cruft.
  69         * (serial_logchar serial_log_command serial_write serial_readchar
  70         serial_send_break serial_close):  Merge common functionality into
  71         serial_logchar.  Clean up rest of routines.
  72         * sparclet-rom.c:  Disembowel.  Leave only download routine.
  73         Download routine now switches to remote target automatically.
  74         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
  75         up MSVC/Win32 problem.
  76         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
  77         or gdb_stderr.
  78         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
  79         * config/sparc/tm-sparclet.h:  Remove override for prompt.
  80
  81 Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>
  82
  83         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
  84         TARGET_BYTE ORDER_SELECTABLE.
  85
  86 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>
  87
  88         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
  89         fields of gdb_callback.
  90         (gdbsim_stop): Add gdbsim_stop to list of supported client
  91         operations.
  92         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
  93         sim_wait where gdb is in a position to handle a long running
  94         function.
  95         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
  96         SIGINT handler.
  97         (gdb_os_poll_quit): New function. Check for a quit pending on the
  98         console.
  99

 101 Wed Apr 16 12:33:06 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 102
 103         * Makefile.in (install-only): Make list of gdbtcl files to install
 104         explicit - was picking up files such as CVS ChangeLog etc.
 105         (install-only): Don't blindly create the directory.
 106
 107 end-sanitize-gdbtk
 108 Thu Apr 17 14:30:04 1997  Per Bothner  <bothner@deneb.cygnus.com>
 109
 110         * defs.h (enum language):  Add language_java.
 111         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 112         * Makefile.in:  Upadte for new files.
 113         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
 114         * symfile.c (deduce_language_from_filename):  Recognize .java.
 115
 116 Thu Apr 17 02:20:23 1997  Doug Evans  <dje@canuck.cygnus.com>
 117
 118         * m32r-stub.c (stash_registers): Rewrite.
 119         (restore_registers): Renamed to restore_and_return.
 120         (cleanup_stash): New function.
 121         (process_exception): New function.

 123
 124         * remote-sim.c (gdbsim_load): Update call to sim_load.
 125         (gdbsim_create_inferior): No longer pass start_address to
 126         sim_create_inferior.

 128
 129 Tue Apr 15 15:31:09 1997  Stan Shebs  <shebs@andros.cygnus.com>
 130
 131         * remote.c (get_offsets): Don't use scanf for interpreting
 132         response to qOffsets.
 133
 134 Tue Apr 15 14:51:04 1997  Ian Lance Taylor  <ian@cygnus.com>
 135
 136         * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
 137         (INSTALL_XFORM1): Remove.
 138         (install-only): Use $(program_transform_name) directly, rather
 139         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 140         (uninstall): Transform name.
 141
 142 Mon Apr 14 17:06:27 1997  Mark Alexander  <marka@cygnus.com>
 143
 144         * remote-mips.c (mips_load): Ensure that PC gets updated
 145         after a load on LSI target.
 146
 147 Mon Apr 14 15:54:51 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 148
 149         * procfs.c (notice_signals): fix typo
 150
 151 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>
 152
 153         * gdbserver/Makefile.in (INSTALL): Change install.sh to
 154         install-sh.
 155
 156 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 157
 158         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 159         since gcc automatically includes it
 160
 161 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 162
 163         * procfs.c: Substantial (but incomplete) changes to support
 164         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 165         struct now has substructs like struct flt_ctl instead of
 166         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 167         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 168         still have the structs and multiple fds, but don't use the
 169         entire struct and the four fds all point to the same thing.
 170         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 171         procfs with reads/writes or use ioctl instead.  We use
 172         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 173         multiple fds or not.  PROC_NAME_FMT is split out into
 174         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 175         STATUS_PROC_NAME_FMT.
 176
 177         (procfs_notice_signals): now a necessary wrapper around
 178         (notice_signals): which are the new guts for noticing signals
 179         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 180         determine whether or not to attempt to open the ctl_fd.
 181         (procfs_read_status): new local function, reads procfs status
 182         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 183         (procfs_write_pckill): new local function, writes a PCKILL
 184         (unconditionally_kill_inferior): remove signo since we now
 185         just call procfs_write_pckill().
 186         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 187         (proc_iterate_over_mappings): the whole function is ifdefed
 188         on UNIXWARE to keep things readable.
 189
 190         Expanded the syscall_table to include new potential sysv4.2mp
 191         members.  Note that all ifdefs of UNIXWARE should be eliminated
 192         if possible or renamed to describe what's being selected for a
 193         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 194         IRIX specific code now also checks it's not UNIXWARE.
 195
 196         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 197         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 198         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 199         "/debug/%d" as PROC_NAME_FMT used to be
 200
 201 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 202
 203         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 204         port.
 205         * config/mn10300/tm-mn10300.h: Likewise.
 206
 207 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 208
 209         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 210         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 211         lousy out-of-date clone of remote.c.
 212
 213 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 214
 215         * remote.c:  Fix problems realized while showering.
 216         * (hexnumlen):  Add prototype.  Use max, not min.
 217         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 218         calculations to properly account for packet overhead.  Also handle
 219         (probably rare) case where remote_register_buf_size isn't set.
 220
 221         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 222         address.
 223         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 224         Make static.
 225         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 226         Record size of response to fetch registers command, use this to
 227         limit size of memory read and write commands.
 228         * (push_remote_target):  New function to make it possible to have
 229         another target switch to the remote target.
 230         * target.h:  Add prototype for push_remote_target.
 231         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 232         for hosts which default to unsigned chars (such as SGI's).
 233         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 234         handled automatically in remote.c.
 235
 236 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 237
 238         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 239         find_pc_sect_function(), find_pc_sect_partial_function(): new
 240         functions for debugging overlays; pc without section is ambiguous.
 241         * breakpoint.[ch]: add section pointer to breakpoint struct;
 242         add section argument to check_duplicates(); check section as well
 243         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 244         breakpoint_thread_match(), bpstat_stop_status()];
 245         add section argument to describe_other_breakpoints();
 246         use INIT_SAL() macro to zero-out new sal structures;
 247         make resolve_sal_pc() fix up the sal's section as well as its pc;
 248         match on section + pc in clear_command() and delete_breakpoint();
 249         account for overlay sections in insert_breakpoints(),
 250         remove_breakpoint() and breakpoint_re_set_one();
 251         all this to support overlays where a PC is not unique.
 252         * exec.c: change xfer_memory() to handle overlay sections.
 253         * findvar.c: change read_var_value() to handle overlay sections.
 254         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 255         * infcmd.c: jump_command() warns against jumping into an overlay
 256         that's not in memory.  Also use INIT_SAL() to initialize sals.
 257         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 258         overlay state information; Also use INIT_SAL() to init sals.
 259         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 260         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 261         memory read/writes in the range 600000 to a00000, and ff680000
 262         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 263         * maint.c: maintenance command "translate-address" supports overlays.
 264         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 265         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 266         this constitutes gdb's internal overlay mapping table.  Add macro
 267         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 268         Add function find_pc_sect_section().
 269         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 270         modify address_info() with overlay smarts; add function sym_info()
 271         to support the INFO SYMBOL command (translate address to symbol(s));
 272         modify disassemble_command() to work on unmapped overlays.
 273         * source.c: use INIT_SAL() to initialize sals.
 274         * symfile.[ch]: change generic_load() to use section's LMA address
 275         instead of VMA address, for overlay sections.
 276         Add numerous functions for finding a PC's section / overlay,
 277         translating between VMA and LMA address ranges, determining if an
 278         overlay section is mapped, etc.  Add several user commands for
 279         overlay debugging.  Add support for a "generic" form of automatically
 280         reading overlay mapping info from the inferior (based on the default
 281         (simple) overlay manager which Cygnus provides as an example).
 282         * symtab.[ch]: add functions find_pc_sect_symtab(),
 283         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 284         for lookup; modify lookup_symbol and decode_line_1() to use them;
 285         modify find_function_start_sal() to account for overlay sections;
 286         add macro INIT_SAL() for initializing struct symtab_and_line.
 287         * target.c: fix a comment in the declaration of target_ops.
 288
 289 Thu Apr  3 10:31:12 1997  Mark Alexander  <marka@cygnus.com>
 290

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