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

 179         TARGET_BYTE ORDER_SELECTABLE.

 181 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>

 184         fields of gdb_callback.
 185         (gdbsim_stop): Add gdbsim_stop to list of supported client
 186         operations.
 187         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 188         sim_wait where gdb is in a position to handle a long running
 189         function.
 190         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 191         SIGINT handler.
 192         (gdb_os_poll_quit): New function. Check for a quit pending on the
 193         console.

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

 207         * Makefile.in:  Update for new files.
 208         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.

 232         (INSTALL_XFORM1): Remove.
 233         (install-only): Use $(program_transform_name) directly, rather
 234         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 235         (uninstall): Transform name.

 249         install-sh.
 250
 251 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 252
 253         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 254         since gcc automatically includes it
 255
 256 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 257
 258         * procfs.c: Substantial (but incomplete) changes to support
 259         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 260         struct now has substructs like struct flt_ctl instead of
 261         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 262         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 263         still have the structs and multiple fds, but don't use the
 264         entire struct and the four fds all point to the same thing.
 265         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 266         procfs with reads/writes or use ioctl instead.  We use
 267         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 268         multiple fds or not.  PROC_NAME_FMT is split out into
 269         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 270         STATUS_PROC_NAME_FMT.
 271
 272         (procfs_notice_signals): now a necessary wrapper around
 273         (notice_signals): which are the new guts for noticing signals
 274         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 275         determine whether or not to attempt to open the ctl_fd.
 276         (procfs_read_status): new local function, reads procfs status
 277         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 278         (procfs_write_pckill): new local function, writes a PCKILL
 279         (unconditionally_kill_inferior): remove signo since we now
 280         just call procfs_write_pckill().
 281         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 282         (proc_iterate_over_mappings): the whole function is ifdefed
 283         on UNIXWARE to keep things readable.
 284
 285         Expanded the syscall_table to include new potential sysv4.2mp
 286         members.  Note that all ifdefs of UNIXWARE should be eliminated
 287         if possible or renamed to describe what's being selected for a
 288         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 289         IRIX specific code now also checks it's not UNIXWARE.
 290
 291         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 292         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 293         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 294         "/debug/%d" as PROC_NAME_FMT used to be
 295
 296 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 297
 298         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 299         port.
 300         * config/mn10300/tm-mn10300.h: Likewise.

 302 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 303
 304         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 305         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 306         lousy out-of-date clone of remote.c.
 307
 308 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 309
 310         * remote.c:  Fix problems realized while showering.
 311         * (hexnumlen):  Add prototype.  Use max, not min.
 312         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 313         calculations to properly account for packet overhead.  Also handle
 314         (probably rare) case where remote_register_buf_size isn't set.
 315
 316         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 317         address.
 318         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 319         Make static.
 320         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 321         Record size of response to fetch registers command, use this to
 322         limit size of memory read and write commands.
 323         * (push_remote_target):  New function to make it possible to have
 324         another target switch to the remote target.
 325         * target.h:  Add prototype for push_remote_target.
 326         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 327         for hosts which default to unsigned chars (such as SGI's).

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