   7
   8         * serial.c (serial_log_command):  Fix fputs_unfiltered calls.
   9
  10         * config/powerpc/tm-ppc-aix4.h, config/rs6000/tm-rs6000-aix4.h
  11         (DONT_RELOCATE_SYMFILE_OBJFILE):  Removed.
  12         * xcoffsolib.h (struct vmap):  Add new members tvma, toffs and dvma,
  13         remove tadj.
  14         * exec.c (bfdsec_to_vmap):  Initialize new vmap members, initialize
  15         tstart and dstart with section VMA.
  16         * rs6000-nat.c (vmap_symtab):  Relocate relative to the VMA in the
  17         object file.
  18         (vmap_ldinfo, xcoff_relocate_core):  Adjust tstart by section offset
  19         of the text section, remove DONT_RELOCATE_SYMFILE_OBJFILE hack.
  20         (vmap_exec):  Relocate relative to the VMA in the object file,
  21         relocate .bss section as well.
  22         (xcoff_relocate_core):  No longer adjust section addresses by VMA.
  23         * rs6000-tdep.c (find_toc_address):  Change type of tocbase
  24         to CORE_ADDR.
  25         * xcoffread.c (secnum_to_bfd_section):  New routine to get
  26         BFD section from CS section number.

  28
  29         * symtab.c (total_number_of_methods):  Avoid core dump if

  31
  32 Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)
  33
  34         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
  35         that directory.
  36         * defs.h utils.c (error warning):  Make message be const.
  37         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
  38         to hook.  Otherwise send it to fputs.
  39         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
  40         the obvious.
  41         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
  42         to _filtered forms to make output appear in GUIs.  Replace all
  43         uses of SERIAL_READCHAR with readchar, which has better error
  44         checking.
  45         * (e7000_parse_device):  Add prototype.
  46         * (readchar):  Improve doc.  Handle random serial errors.
  47         * (expect):  Disable notice_quit code.  It's busted.  Remove
  48         serial error handling (it's now handled in readchar).  Remove
  49         remote_debug echoing.  That's handled in readchar as well.
  50         * (e7000_parse_device):  Remove serial_flag arg.  It's not
  51         necessary.
  52         * (e7000_open):  Split into two pieces.  Second part is
  53         e7000_start_remote, and is error protected.  Now, when we connect
  54         to the target, we setup the initial frame and registers so that
  55         the user gets an immediate indication of where the target is.
  56         * (gch):  Remove debug output.  That's handled by readchar.
  57         * (e7000_read_inferior_memory):  Handle errors better.
  58         * (_initialize_remote_e7000):  Get rid of `<xxx>' things from
  59         command names.  They show up when doing completion and confuse
  60         things horribly.
  61         * ser-e7kpc.c:  Remove the last seven months of brain damage.  Get
  62         rid of the DLL's since we can access the device directly from Win32s
  63         and Win95.  Get rid of debugify crud.
  64         * serial.c:  Remove debugify cruft.
  65         * (serial_logchar serial_log_command serial_write serial_readchar
  66         serial_send_break serial_close):  Merge common functionality into
  67         serial_logchar.  Clean up rest of routines.
  68         * sparclet-rom.c:  Disembowel.  Leave only download routine.
  69         Download routine now switches to remote target automatically.
  70         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
  71         up MSVC/Win32 problem.
  72         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
  73         or gdb_stderr.
  74         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
  75         * config/sparc/tm-sparclet.h:  Remove override for prompt.
  76
  77 Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>
  78
  79         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
  80         TARGET_BYTE ORDER_SELECTABLE.
  81
  82 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>
  83
  84         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
  85         fields of gdb_callback.
  86         (gdbsim_stop): Add gdbsim_stop to list of supported client
  87         operations.
  88         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
  89         sim_wait where gdb is in a position to handle a long running
  90         function.
  91         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
  92         SIGINT handler.
  93         (gdb_os_poll_quit): New function. Check for a quit pending on the
  94         console.
  95
  96 start-sanitize-gdbtk
  97 Wed Apr 16 12:33:06 1997  Andrew Cagney  <cagney@b1.cygnus.com>
  98
  99         * Makefile.in (install-only): Make list of gdbtcl files to install
 100         explicit - was picking up files such as CVS ChangeLog etc.
 101         (install-only): Don't blindly create the directory.
 102
 103 end-sanitize-gdbtk
 104 Thu Apr 17 14:30:04 1997  Per Bothner  <bothner@deneb.cygnus.com>
 105
 106         * defs.h (enum language):  Add language_java.
 107         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 108         * Makefile.in:  Upadte for new files.
 109         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
 110         * symfile.c (deduce_language_from_filename):  Recognize .java.
 111
 112 Thu Apr 17 02:20:23 1997  Doug Evans  <dje@canuck.cygnus.com>
 113
 114         * m32r-stub.c (stash_registers): Rewrite.
 115         (restore_registers): Renamed to restore_and_return.
 116         (cleanup_stash): New function.

 124
 125 Tue Apr 15 15:31:09 1997  Stan Shebs  <shebs@andros.cygnus.com>
 126
 127         * remote.c (get_offsets): Don't use scanf for interpreting
 128         response to qOffsets.
 129
 130 Tue Apr 15 14:51:04 1997  Ian Lance Taylor  <ian@cygnus.com>
 131
 132         * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
 133         (INSTALL_XFORM1): Remove.
 134         (install-only): Use $(program_transform_name) directly, rather
 135         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 136         (uninstall): Transform name.
 137
 138 Mon Apr 14 17:06:27 1997  Mark Alexander  <marka@cygnus.com>
 139
 140         * remote-mips.c (mips_load): Ensure that PC gets updated
 141         after a load on LSI target.
 142
 143 Mon Apr 14 15:54:51 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 144
 145         * procfs.c (notice_signals): fix typo
 146
 147 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>
 148
 149         * gdbserver/Makefile.in (INSTALL): Change install.sh to
 150         install-sh.
 151
 152 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 153
 154         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 155         since gcc automatically includes it
 156
 157 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 158
 159         * procfs.c: Substantial (but incomplete) changes to support
 160         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 161         struct now has substructs like struct flt_ctl instead of
 162         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 163         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 164         still have the structs and multiple fds, but don't use the
 165         entire struct and the four fds all point to the same thing.
 166         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 167         procfs with reads/writes or use ioctl instead.  We use
 168         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 169         multiple fds or not.  PROC_NAME_FMT is split out into
 170         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 171         STATUS_PROC_NAME_FMT.
 172
 173         (procfs_notice_signals): now a necessary wrapper around
 174         (notice_signals): which are the new guts for noticing signals
 175         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 176         determine whether or not to attempt to open the ctl_fd.
 177         (procfs_read_status): new local function, reads procfs status
 178         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 179         (procfs_write_pckill): new local function, writes a PCKILL
 180         (unconditionally_kill_inferior): remove signo since we now
 181         just call procfs_write_pckill().
 182         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 183         (proc_iterate_over_mappings): the whole function is ifdefed
 184         on UNIXWARE to keep things readable.
 185
 186         Expanded the syscall_table to include new potential sysv4.2mp
 187         members.  Note that all ifdefs of UNIXWARE should be eliminated
 188         if possible or renamed to describe what's being selected for a
 189         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 190         IRIX specific code now also checks it's not UNIXWARE.
 191
 192         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 193         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 194         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 195         "/debug/%d" as PROC_NAME_FMT used to be
 196
 197 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 198
 199         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 200         port.
 201         * config/mn10300/tm-mn10300.h: Likewise.
 202
 203 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 204
 205         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 206         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 207         lousy out-of-date clone of remote.c.
 208
 209 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 210
 211         * remote.c:  Fix problems realized while showering.
 212         * (hexnumlen):  Add prototype.  Use max, not min.
 213         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 214         calculations to properly account for packet overhead.  Also handle
 215         (probably rare) case where remote_register_buf_size isn't set.
 216
 217         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 218         address.
 219         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 220         Make static.
 221         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 222         Record size of response to fetch registers command, use this to
 223         limit size of memory read and write commands.
 224         * (push_remote_target):  New function to make it possible to have
 225         another target switch to the remote target.
 226         * target.h:  Add prototype for push_remote_target.
 227         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 228         for hosts which default to unsigned chars (such as SGI's).
 229         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 230         handled automatically in remote.c.
 231
 232 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 233
 234         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 235         find_pc_sect_function(), find_pc_sect_partial_function(): new
 236         functions for debugging overlays; pc without section is ambiguous.
 237         * breakpoint.[ch]: add section pointer to breakpoint struct;
 238         add section argument to check_duplicates(); check section as well
 239         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 240         breakpoint_thread_match(), bpstat_stop_status()];
 241         add section argument to describe_other_breakpoints();
 242         use INIT_SAL() macro to zero-out new sal structures;
 243         make resolve_sal_pc() fix up the sal's section as well as its pc;
 244         match on section + pc in clear_command() and delete_breakpoint();
 245         account for overlay sections in insert_breakpoints(),
 246         remove_breakpoint() and breakpoint_re_set_one();
 247         all this to support overlays where a PC is not unique.
 248         * exec.c: change xfer_memory() to handle overlay sections.
 249         * findvar.c: change read_var_value() to handle overlay sections.
 250         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 251         * infcmd.c: jump_command() warns against jumping into an overlay
 252         that's not in memory.  Also use INIT_SAL() to initialize sals.
 253         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 254         overlay state information; Also use INIT_SAL() to init sals.
 255         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 256         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 257         memory read/writes in the range 600000 to a00000, and ff680000
 258         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 259         * maint.c: maintenance command "translate-address" supports overlays.
 260         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 261         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 262         this constitutes gdb's internal overlay mapping table.  Add macro
 263         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 264         Add function find_pc_sect_section().
 265         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 266         modify address_info() with overlay smarts; add function sym_info()
 267         to support the INFO SYMBOL command (translate address to symbol(s));
 268         modify disassemble_command() to work on unmapped overlays.
 269         * source.c: use INIT_SAL() to initialize sals.
 270         * symfile.[ch]: change generic_load() to use section's LMA address
 271         instead of VMA address, for overlay sections.
 272         Add numerous functions for finding a PC's section / overlay,
 273         translating between VMA and LMA address ranges, determining if an
 274         overlay section is mapped, etc.  Add several user commands for
 275         overlay debugging.  Add support for a "generic" form of automatically
 276         reading overlay mapping info from the inferior (based on the default
 277         (simple) overlay manager which Cygnus provides as an example).
 278         * symtab.[ch]: add functions find_pc_sect_symtab(),
 279         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 280         for lookup; modify lookup_symbol and decode_line_1() to use them;
 281         modify find_function_start_sal() to account for overlay sections;
 282         add macro INIT_SAL() for initializing struct symtab_and_line.
 283         * target.c: fix a comment in the declaration of target_ops.
 284
 285 Thu Apr  3 10:31:12 1997  Mark Alexander  <marka@cygnus.com>
 286
 287         * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,
 288         mips_skip_stub, mips_ignore_helper): New functions for dealing
 289         with MIPS16 call/return thunks.
 290         (mips_init_frame_pc_first): New function to implement
 291         INIT_FRAME_PC_FIRST macro; includes code from old macro plus
 292         new code to skip over MIPS16 thunks.
 293         (mips_frame_chain): Skip over MIPS16 thunks.
 294         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
 295         mips_skip_stub, mips_ignore_helper): Declare.
 296         (IN_SOLIB_CALL_TRAMPOLINE, IN_SOLIB_RETURN_TRAMPOLINE,
 297         SKIP_TRAMPOLINE_CODE, IGNORE_HELPER_CALL): New macros that invoke
 298         the above functions.
 299         (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
 300         (mips_init_frame_pc): Declare.
 301         * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
 302         to decide if certain library function calls should be ignored.
 303
 304 Wed Apr  2 14:16:51 1997  Doug Evans  <dje@canuck.cygnus.com>
 305
 306         * remote-sim.c (gdbsim_open): Check return code from sim_open.
 307         Update call to sim_open (new arg SIM_OPEN_DEBUG).

1141         ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
1142         arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
