 122         to CORE_ADDR.
 123         * xcoffread.c (secnum_to_bfd_section):  New routine to get
 124         BFD section from CS section number.

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

 174 Fri Apr 18 13:38:19 1997  Doug Evans  <dje@canuck.cygnus.com>
 175
 176         * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
 177         TARGET_BYTE ORDER_SELECTABLE.
 178
 179 Fri Apr 18 16:52:41 1997  Andrew Cagney  <cagney@b1.cygnus.com>

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

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

 204         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 205         * Makefile.in:  Update for new files.
 206         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
 207         * symfile.c (deduce_language_from_filename):  Recognize .java.

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

 247         install-sh.
 248
 249 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 250
 251         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 252         since gcc automatically includes it
 253
 254 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 255
 256         * procfs.c: Substantial (but incomplete) changes to support
 257         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 258         struct now has substructs like struct flt_ctl instead of
 259         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 260         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 261         still have the structs and multiple fds, but don't use the
 262         entire struct and the four fds all point to the same thing.
 263         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 264         procfs with reads/writes or use ioctl instead.  We use
 265         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 266         multiple fds or not.  PROC_NAME_FMT is split out into
 267         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 268         STATUS_PROC_NAME_FMT.
 269
 270         (procfs_notice_signals): now a necessary wrapper around
 271         (notice_signals): which are the new guts for noticing signals
 272         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 273         determine whether or not to attempt to open the ctl_fd.
 274         (procfs_read_status): new local function, reads procfs status
 275         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 276         (procfs_write_pckill): new local function, writes a PCKILL
 277         (unconditionally_kill_inferior): remove signo since we now
 278         just call procfs_write_pckill().
 279         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 280         (proc_iterate_over_mappings): the whole function is ifdefed
 281         on UNIXWARE to keep things readable.
 282
 283         Expanded the syscall_table to include new potential sysv4.2mp
 284         members.  Note that all ifdefs of UNIXWARE should be eliminated
 285         if possible or renamed to describe what's being selected for a
 286         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 287         IRIX specific code now also checks it's not UNIXWARE.
 288
 289         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 290         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 291         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 292         "/debug/%d" as PROC_NAME_FMT used to be
 293
 294 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 295
 296         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 297         port.
 298         * config/mn10300/tm-mn10300.h: Likewise.

 300 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 301
 302         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 303         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 304         lousy out-of-date clone of remote.c.
 305
 306 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 307
 308         * remote.c:  Fix problems realized while showering.
 309         * (hexnumlen):  Add prototype.  Use max, not min.
 310         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 311         calculations to properly account for packet overhead.  Also handle
 312         (probably rare) case where remote_register_buf_size isn't set.
 313
 314         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 315         address.
 316         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 317         Make static.
 318         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 319         Record size of response to fetch registers command, use this to
 320         limit size of memory read and write commands.
 321         * (push_remote_target):  New function to make it possible to have
 322         another target switch to the remote target.
 323         * target.h:  Add prototype for push_remote_target.
 324         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 325         for hosts which default to unsigned chars (such as SGI's).
 326         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 327         handled automatically in remote.c.

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