  30         tstart and dstart with section VMA.
  31         * rs6000-nat.c (vmap_symtab):  Relocate relative to the VMA in the
  32         object file.

  34         of the text section, remove DONT_RELOCATE_SYMFILE_OBJFILE hack.
  35         (vmap_exec):  Relocate relative to the VMA in the object file,
  36         relocate .bss section as well.
  37         (xcoff_relocate_core):  No longer adjust section addresses by VMA.

  46
  47 Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)
  48
  49         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
  50         that directory.
  51         * defs.h utils.c (error warning):  Make message be const.
  52         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
  53         to hook.  Otherwise send it to fputs.
  54         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
  55         the obvious.
  56         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
  57         to _filtered forms to make output appear in GUIs.  Replace all
  58         uses of SERIAL_READCHAR with readchar, which has better error
  59         checking.
  60         * (e7000_parse_device):  Add prototype.
  61         (readchar):  Improve doc.  Handle random serial errors.
  62         (expect):  Disable notice_quit code.  It's busted.  Remove
  63         serial error handling (it's now handled in readchar).  Remove
  64         remote_debug echoing.  That's handled in readchar as well.
  65         (e7000_parse_device):  Remove serial_flag arg.  It's not
  66         necessary.
  67         (e7000_open):  Split into two pieces.  Second part is
  68         e7000_start_remote, and is error protected.  Now, when we connect
  69         to the target, we setup the initial frame and registers so that
  70         the user gets an immediate indication of where the target is.
  71         (gch):  Remove debug output.  That's handled by readchar.
  72         (e7000_read_inferior_memory):  Handle errors better.
  73         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
  74         command names.  They show up when doing completion and confuse
  75         things horribly.
  76         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
  77         directly from Win32s and Win95.  Get rid of debugify crud.
  78         * serial.c:  Remove debugify cruft.
  79         * (serial_logchar serial_log_command serial_write serial_readchar
  80         serial_send_break serial_close):  Merge common functionality into
  81         serial_logchar.  Clean up rest of routines.
  82         * sparclet-rom.c:  Disembowel.  Leave only download routine.
  83         Download routine now switches to remote target automatically.
  84         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
  85         up MSVC/Win32 problem.
  86         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
  87         or gdb_stderr.
  88         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
  89         * config/sparc/tm-sparclet.h:  Remove override for prompt.
  90
  91 Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>
  92
  93         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
  94         TARGET_BYTE ORDER_SELECTABLE.
  95
  96 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>
  97
  98         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
  99         fields of gdb_callback.
 100         (gdbsim_stop): Add gdbsim_stop to list of supported client
 101         operations.
 102         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 103         sim_wait where gdb is in a position to handle a long running
 104         function.
 105         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 106         SIGINT handler.
 107         (gdb_os_poll_quit): New function. Check for a quit pending on the
 108         console.
 109
 110 start-sanitize-gdbtk
 111 Wed Apr 16 12:33:06 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 112
 113         * Makefile.in (install-only): Make list of gdbtcl files to install
 114         explicit - was picking up files such as ChangeLog etc.
 115         (install-only): Don't blindly create the directory.
 116
 117 end-sanitize-gdbtk
 118 Thu Apr 17 14:30:04 1997  Per Bothner  <bothner@deneb.cygnus.com>
 119
 120         * defs.h (enum language):  Add language_java.
 121         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 122         * Makefile.in:  Update for new files.
 123         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
 124         * symfile.c (deduce_language_from_filename):  Recognize .java.
 125
 126 Thu Apr 17 02:20:23 1997  Doug Evans  <dje@canuck.cygnus.com>
 127
 128         * m32r-stub.c (stash_registers): Rewrite.
 129         (restore_registers): Renamed to restore_and_return.
 130         (cleanup_stash): New function.

 133
 134         * remote-sim.c (gdbsim_load): Update call to sim_load.
 135         (gdbsim_create_inferior): No longer pass start_address to
 136         sim_create_inferior.

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

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