 108         to CORE_ADDR.
 109         * xcoffread.c (secnum_to_bfd_section):  New routine to get
 110         BFD section from CS section number.

 115
 116 Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)
 117
 118         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
 119         that directory.
 120         * defs.h utils.c (error warning):  Make message be const.
 121         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
 122         to hook.  Otherwise send it to fputs.
 123         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
 124         the obvious.
 125         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
 126         to _filtered forms to make output appear in GUIs.  Replace all
 127         uses of SERIAL_READCHAR with readchar, which has better error
 128         checking.
 129         * (e7000_parse_device):  Add prototype.
 130         (readchar):  Improve doc.  Handle random serial errors.
 131         (expect):  Disable notice_quit code.  It's busted.  Remove
 132         serial error handling (it's now handled in readchar).  Remove
 133         remote_debug echoing.  That's handled in readchar as well.
 134         (e7000_parse_device):  Remove serial_flag arg.  It's not
 135         necessary.
 136         (e7000_open):  Split into two pieces.  Second part is
 137         e7000_start_remote, and is error protected.  Now, when we connect
 138         to the target, we setup the initial frame and registers so that
 139         the user gets an immediate indication of where the target is.
 140         (gch):  Remove debug output.  That's handled by readchar.
 141         (e7000_read_inferior_memory):  Handle errors better.
 142         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
 143         command names.  They show up when doing completion and confuse
 144         things horribly.
 145         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
 146         directly from Win32s and Win95.  Get rid of debugify crud.
 147         * serial.c:  Remove debugify cruft.
 148         * (serial_logchar serial_log_command serial_write serial_readchar
 149         serial_send_break serial_close):  Merge common functionality into
 150         serial_logchar.  Clean up rest of routines.
 151         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 152         Download routine now switches to remote target automatically.
 153         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 154         up MSVC/Win32 problem.
 155         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
 156         or gdb_stderr.
 157         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
 158         * config/sparc/tm-sparclet.h:  Remove override for prompt.

 160 Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>
 161
 162         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
 163         TARGET_BYTE ORDER_SELECTABLE.
 164
 165 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 166
 167         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
 168         fields of gdb_callback.
 169         (gdbsim_stop): Add gdbsim_stop to list of supported client
 170         operations.
 171         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 172         sim_wait where gdb is in a position to handle a long running
 173         function.
 174         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 175         SIGINT handler.
 176         (gdb_os_poll_quit): New function. Check for a quit pending on the
 177         console.

 180 Wed Apr 16 12:33:06 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 181
 182         * Makefile.in (install-only): Make list of gdbtcl files to install
 183         explicit - was picking up files such as ChangeLog etc.
 184         (install-only): Don't blindly create the directory.

 187 Thu Apr 17 14:30:04 1997  Per Bothner  <bothner@deneb.cygnus.com>

 190         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 191         * Makefile.in:  Update for new files.
 192         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
 193         * symfile.c (deduce_language_from_filename):  Recognize .java.

 211         response to qOffsets.

 216         (INSTALL_XFORM1): Remove.
 217         (install-only): Use $(program_transform_name) directly, rather
 218         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 219         (uninstall): Transform name.
 220
 221 Mon Apr 14 17:06:27 1997  Mark Alexander  <marka@cygnus.com>

 224         after a load on LSI target.
 225
 226 Mon Apr 14 15:54:51 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 227
 228         * procfs.c (notice_signals): fix typo

 230 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>

 233         install-sh.
 234
 235 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 236
 237         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 238         since gcc automatically includes it
 239
 240 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 241
 242         * procfs.c: Substantial (but incomplete) changes to support
 243         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 244         struct now has substructs like struct flt_ctl instead of
 245         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 246         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 247         still have the structs and multiple fds, but don't use the
 248         entire struct and the four fds all point to the same thing.
 249         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 250         procfs with reads/writes or use ioctl instead.  We use
 251         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 252         multiple fds or not.  PROC_NAME_FMT is split out into
 253         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 254         STATUS_PROC_NAME_FMT.
 255
 256         (procfs_notice_signals): now a necessary wrapper around
 257         (notice_signals): which are the new guts for noticing signals
 258         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 259         determine whether or not to attempt to open the ctl_fd.
 260         (procfs_read_status): new local function, reads procfs status
 261         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 262         (procfs_write_pckill): new local function, writes a PCKILL
 263         (unconditionally_kill_inferior): remove signo since we now
 264         just call procfs_write_pckill().
 265         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 266         (proc_iterate_over_mappings): the whole function is ifdefed
 267         on UNIXWARE to keep things readable.
 268
 269         Expanded the syscall_table to include new potential sysv4.2mp
 270         members.  Note that all ifdefs of UNIXWARE should be eliminated
 271         if possible or renamed to describe what's being selected for a
 272         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 273         IRIX specific code now also checks it's not UNIXWARE.
 274
 275         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 276         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 277         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 278         "/debug/%d" as PROC_NAME_FMT used to be
 279
 280 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 281
 282         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 283         port.
 284         * config/mn10300/tm-mn10300.h: Likewise.

 286 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 287
 288         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 289         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 290         lousy out-of-date clone of remote.c.
 291
 292 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 293
 294         * remote.c:  Fix problems realized while showering.
 295         * (hexnumlen):  Add prototype.  Use max, not min.
 296         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 297         calculations to properly account for packet overhead.  Also handle
 298         (probably rare) case where remote_register_buf_size isn't set.
 299
 300         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 301         address.
 302         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 303         Make static.
 304         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 305         Record size of response to fetch registers command, use this to
 306         limit size of memory read and write commands.
 307         * (push_remote_target):  New function to make it possible to have
 308         another target switch to the remote target.
 309         * target.h:  Add prototype for push_remote_target.
 310         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 311         for hosts which default to unsigned chars (such as SGI's).
 312         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 313         handled automatically in remote.c.
 314
 315 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 316
 317         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 318         find_pc_sect_function(), find_pc_sect_partial_function(): new
 319         functions for debugging overlays; pc without section is ambiguous.
 320         * breakpoint.[ch]: add section pointer to breakpoint struct;
 321         add section argument to check_duplicates(); check section as well
 322         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 323         breakpoint_thread_match(), bpstat_stop_status()];
 324         add section argument to describe_other_breakpoints();
 325         use INIT_SAL() macro to zero-out new sal structures;
 326         make resolve_sal_pc() fix up the sal's section as well as its pc;
 327         match on section + pc in clear_command() and delete_breakpoint();
 328         account for overlay sections in insert_breakpoints(),
 329         remove_breakpoint() and breakpoint_re_set_one();
 330         all this to support overlays where a PC is not unique.
 331         * exec.c: change xfer_memory() to handle overlay sections.
 332         * findvar.c: change read_var_value() to handle overlay sections.
 333         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 334         * infcmd.c: jump_command() warns against jumping into an overlay
 335         that's not in memory.  Also use INIT_SAL() to initialize sals.
 336         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 337         overlay state information; Also use INIT_SAL() to init sals.
 338         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 339         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 340         memory read/writes in the range 600000 to a00000, and ff680000
 341         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 342         * maint.c: maintenance command "translate-address" supports overlays.
 343         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 344         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 345         this constitutes gdb's internal overlay mapping table.  Add macro
 346         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 347         Add function find_pc_sect_section().
 348         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 349         modify address_info() with overlay smarts; add function sym_info()
 350         to support the INFO SYMBOL command (translate address to symbol(s));
 351         modify disassemble_command() to work on unmapped overlays.
 352         * source.c: use INIT_SAL() to initialize sals.
 353         * symfile.[ch]: change generic_load() to use section's LMA address
 354         instead of VMA address, for overlay sections.
 355         Add numerous functions for finding a PC's section / overlay,
 356         translating between VMA and LMA address ranges, determining if an
 357         overlay section is mapped, etc.  Add several user commands for
 358         overlay debugging.  Add support for a "generic" form of automatically
 359         reading overlay mapping info from the inferior (based on the default
 360         (simple) overlay manager which Cygnus provides as an example).
 361         * symtab.[ch]: add functions find_pc_sect_symtab(),
 362         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 363         for lookup; modify lookup_symbol and decode_line_1() to use them;
 364         modify find_function_start_sal() to account for overlay sections;
 365         add macro INIT_SAL() for initializing struct symtab_and_line.
 366         * target.c: fix a comment in the declaration of target_ops.
