 111         to CORE_ADDR.
 112         * xcoffread.c (secnum_to_bfd_section):  New routine to get
 113         BFD section from CS section number.

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

 163 Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>
 164
 165         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
 166         TARGET_BYTE ORDER_SELECTABLE.
 167
 168 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>

 170         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
 171         fields of gdb_callback.
 172         (gdbsim_stop): Add gdbsim_stop to list of supported client
 173         operations.
 174         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 175         sim_wait where gdb is in a position to handle a long running
 176         function.
 177         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 178         SIGINT handler.
 179         (gdb_os_poll_quit): New function. Check for a quit pending on the
 180         console.

 183 Wed Apr 16 12:33:06 1997  Andrew Cagney  <cagney@b1.cygnus.com>
 184

 186         explicit - was picking up files such as ChangeLog etc.
 187         (install-only): Don't blindly create the directory.

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

 214         response to qOffsets.

 219         (INSTALL_XFORM1): Remove.
 220         (install-only): Use $(program_transform_name) directly, rather
 221         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 222         (uninstall): Transform name.

 227         after a load on LSI target.
 228
 229 Mon Apr 14 15:54:51 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 230
 231         * procfs.c (notice_signals): fix typo
 232
 233 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>
 234

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

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