  25         tstart and dstart with section VMA.
  26         * rs6000-nat.c (vmap_symtab):  Relocate relative to the VMA in the
  27         object file.
  28         (vmap_ldinfo, xcoff_relocate_core):  Adjust tstart by section offset
  29         of the text section, remove DONT_RELOCATE_SYMFILE_OBJFILE hack.
  30         (vmap_exec):  Relocate relative to the VMA in the object file,
  31         relocate .bss section as well.
  32         (xcoff_relocate_core):  No longer adjust section addresses by VMA.
  33         * rs6000-tdep.c (find_toc_address):  Change type of tocbase
  34         to CORE_ADDR.
  35         * xcoffread.c (secnum_to_bfd_section):  New routine to get
  36         BFD section from CS section number.
  37         (scan_xcoff_symtab):  Make toc_offset section relative.
  38
  39         * symtab.c (total_number_of_methods):  Avoid core dump if

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

 106 Wed Apr 16 12:33:06 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 107
 108         * Makefile.in (install-only): Make list of gdbtcl files to install
 109         explicit - was picking up files such as ChangeLog etc.
 110         (install-only): Don't blindly create the directory.
 111
 112 end-sanitize-gdbtk
 113 Thu Apr 17 14:30:04 1997  Per Bothner  <bothner@deneb.cygnus.com>
 114
 115         * defs.h (enum language):  Add language_java.
 116         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 117         * Makefile.in:  Update for new files.
 118         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
 119         * symfile.c (deduce_language_from_filename):  Recognize .java.

 121 Thu Apr 17 02:20:23 1997  Doug Evans  <dje@canuck.cygnus.com>
 122
 123         * m32r-stub.c (stash_registers): Rewrite.
 124         (restore_registers): Renamed to restore_and_return.
 125         (cleanup_stash): New function.

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

 297         mips_skip_stub, mips_ignore_helper): New functions for dealing
 298         with MIPS16 call/return thunks.
 299         (mips_init_frame_pc_first): New function to implement
 300         INIT_FRAME_PC_FIRST macro; includes code from old macro plus
 301         new code to skip over MIPS16 thunks.
 302         (mips_frame_chain): Skip over MIPS16 thunks.
 303         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
 304         mips_skip_stub, mips_ignore_helper): Declare.
 305         (IN_SOLIB_CALL_TRAMPOLINE, IN_SOLIB_RETURN_TRAMPOLINE,
 306         SKIP_TRAMPOLINE_CODE, IGNORE_HELPER_CALL): New macros that invoke
 307         the above functions.
 308         (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
 309         (mips_init_frame_pc): Declare.
 310         * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro

1146         ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
1147         arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
