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

 184         TARGET_BYTE ORDER_SELECTABLE.
 185
 186 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>

 188         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
 189         fields of gdb_callback.
 190         (gdbsim_stop): Add gdbsim_stop to list of supported client
 191         operations.
 192         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 193         sim_wait where gdb is in a position to handle a long running
 194         function.
 195         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 196         SIGINT handler.
 197         (gdb_os_poll_quit): New function. Check for a quit pending on the
 198         console.

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

 211         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 212         * Makefile.in:  Update for new files.
 213         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.

 237         (INSTALL_XFORM1): Remove.
 238         (install-only): Use $(program_transform_name) directly, rather
 239         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 240         (uninstall): Transform name.

 254         install-sh.
 255
 256 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 257
 258         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 259         since gcc automatically includes it
 260
 261 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 262
 263         * procfs.c: Substantial (but incomplete) changes to support
 264         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 265         struct now has substructs like struct flt_ctl instead of
 266         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 267         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 268         still have the structs and multiple fds, but don't use the
 269         entire struct and the four fds all point to the same thing.
 270         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 271         procfs with reads/writes or use ioctl instead.  We use
 272         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 273         multiple fds or not.  PROC_NAME_FMT is split out into
 274         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 275         STATUS_PROC_NAME_FMT.
 276
 277         (procfs_notice_signals): now a necessary wrapper around
 278         (notice_signals): which are the new guts for noticing signals
 279         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 280         determine whether or not to attempt to open the ctl_fd.
 281         (procfs_read_status): new local function, reads procfs status
 282         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 283         (procfs_write_pckill): new local function, writes a PCKILL
 284         (unconditionally_kill_inferior): remove signo since we now
 285         just call procfs_write_pckill().
 286         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 287         (proc_iterate_over_mappings): the whole function is ifdefed
 288         on UNIXWARE to keep things readable.
 289
 290         Expanded the syscall_table to include new potential sysv4.2mp
 291         members.  Note that all ifdefs of UNIXWARE should be eliminated
 292         if possible or renamed to describe what's being selected for a
 293         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 294         IRIX specific code now also checks it's not UNIXWARE.
 295
 296         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 297         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 298         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 299         "/debug/%d" as PROC_NAME_FMT used to be
 300
 301 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 302
 303         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 304         port.
 305         * config/mn10300/tm-mn10300.h: Likewise.

 307 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 308
 309         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 310         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 311         lousy out-of-date clone of remote.c.
 312
 313 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 314
 315         * remote.c:  Fix problems realized while showering.
 316         * (hexnumlen):  Add prototype.  Use max, not min.
 317         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 318         calculations to properly account for packet overhead.  Also handle
 319         (probably rare) case where remote_register_buf_size isn't set.
 320
 321         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 322         address.
 323         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 324         Make static.
 325         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 326         Record size of response to fetch registers command, use this to
 327         limit size of memory read and write commands.
 328         * (push_remote_target):  New function to make it possible to have

 337
 338         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 339         find_pc_sect_function(), find_pc_sect_partial_function(): new
 340         functions for debugging overlays; pc without section is ambiguous.
 341         * breakpoint.[ch]: add section pointer to breakpoint struct;
 342         add section argument to check_duplicates(); check section as well
 343         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 344         breakpoint_thread_match(), bpstat_stop_status()];
 345         add section argument to describe_other_breakpoints();
 346         use INIT_SAL() macro to zero-out new sal structures;
 347         make resolve_sal_pc() fix up the sal's section as well as its pc;
 348         match on section + pc in clear_command() and delete_breakpoint();
 349         account for overlay sections in insert_breakpoints(),
 350         remove_breakpoint() and breakpoint_re_set_one();
 351         all this to support overlays where a PC is not unique.
 352         * exec.c: change xfer_memory() to handle overlay sections.
 353         * findvar.c: change read_var_value() to handle overlay sections.
 354         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 355         * infcmd.c: jump_command() warns against jumping into an overlay
 356         that's not in memory.  Also use INIT_SAL() to initialize sals.
 357         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 358         overlay state information; Also use INIT_SAL() to init sals.
 359         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 360         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 361         memory read/writes in the range 600000 to a00000, and ff680000
 362         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 363         * maint.c: maintenance command "translate-address" supports overlays.
 364         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 365         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 366         this constitutes gdb's internal overlay mapping table.  Add macro
 367         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 368         Add function find_pc_sect_section().
 369         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 370         modify address_info() with overlay smarts; add function sym_info()
 371         to support the INFO SYMBOL command (translate address to symbol(s));
 372         modify disassemble_command() to work on unmapped overlays.
 373         * source.c: use INIT_SAL() to initialize sals.
 374         * symfile.[ch]: change generic_load() to use section's LMA address
 375         instead of VMA address, for overlay sections.
 376         Add numerous functions for finding a PC's section / overlay,
 377         translating between VMA and LMA address ranges, determining if an
 378         overlay section is mapped, etc.  Add several user commands for
 379         overlay debugging.  Add support for a "generic" form of automatically
 380         reading overlay mapping info from the inferior (based on the default
 381         (simple) overlay manager which Cygnus provides as an example).
 382         * symtab.[ch]: add functions find_pc_sect_symtab(),
 383         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 384         for lookup; modify lookup_symbol and decode_line_1() to use them;
 385         modify find_function_start_sal() to account for overlay sections;
 386         add macro INIT_SAL() for initializing struct symtab_and_line.
 387         * target.c: fix a comment in the declaration of target_ops.
