 113         (vmap_exec):  Relocate relative to the VMA in the object file,
 114         relocate .bss section as well.

 117         to CORE_ADDR.
 118         * xcoffread.c (secnum_to_bfd_section):  New routine to get
 119         BFD section from CS section number.

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

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

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

 199         * java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
 200         * Makefile.in:  Update for new files.
 201         * objfiles.c (allocate_objfile):  Allow NULL bfd argument.
 202         * symfile.c (deduce_language_from_filename):  Recognize .java.

 225         (INSTALL_XFORM1): Remove.
 226         (install-only): Use $(program_transform_name) directly, rather
 227         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 228         (uninstall): Transform name.

 242         install-sh.
 243
 244 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 245
 246         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 247         since gcc automatically includes it
 248
 249 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 250
 251         * procfs.c: Substantial (but incomplete) changes to support
 252         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 253         struct now has substructs like struct flt_ctl instead of
 254         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 255         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 256         still have the structs and multiple fds, but don't use the
 257         entire struct and the four fds all point to the same thing.
 258         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 259         procfs with reads/writes or use ioctl instead.  We use
 260         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 261         multiple fds or not.  PROC_NAME_FMT is split out into
 262         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 263         STATUS_PROC_NAME_FMT.
 264
 265         (procfs_notice_signals): now a necessary wrapper around
 266         (notice_signals): which are the new guts for noticing signals
 267         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 268         determine whether or not to attempt to open the ctl_fd.
 269         (procfs_read_status): new local function, reads procfs status
 270         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 271         (procfs_write_pckill): new local function, writes a PCKILL
 272         (unconditionally_kill_inferior): remove signo since we now
 273         just call procfs_write_pckill().
 274         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 275         (proc_iterate_over_mappings): the whole function is ifdefed
 276         on UNIXWARE to keep things readable.
 277
 278         Expanded the syscall_table to include new potential sysv4.2mp
 279         members.  Note that all ifdefs of UNIXWARE should be eliminated
 280         if possible or renamed to describe what's being selected for a
 281         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 282         IRIX specific code now also checks it's not UNIXWARE.
 283
 284         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 285         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 286         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 287         "/debug/%d" as PROC_NAME_FMT used to be
 288
 289 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 290
 291         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 292         port.
 293         * config/mn10300/tm-mn10300.h: Likewise.

 295 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 296
 297         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 298         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 299         lousy out-of-date clone of remote.c.
 300
 301 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 302
 303         * remote.c:  Fix problems realized while showering.
 304         * (hexnumlen):  Add prototype.  Use max, not min.
 305         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 306         calculations to properly account for packet overhead.  Also handle
 307         (probably rare) case where remote_register_buf_size isn't set.
 308
 309         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 310         address.
 311         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 312         Make static.
 313         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 314         Record size of response to fetch registers command, use this to
 315         limit size of memory read and write commands.
 316         * (push_remote_target):  New function to make it possible to have
 317         another target switch to the remote target.
 318         * target.h:  Add prototype for push_remote_target.
 319         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 320         for hosts which default to unsigned chars (such as SGI's).
 321         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 322         handled automatically in remote.c.
 323
 324 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 325
 326         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 327         find_pc_sect_function(), find_pc_sect_partial_function(): new
 328         functions for debugging overlays; pc without section is ambiguous.
 329         * breakpoint.[ch]: add section pointer to breakpoint struct;
 330         add section argument to check_duplicates(); check section as well
 331         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 332         breakpoint_thread_match(), bpstat_stop_status()];
 333         add section argument to describe_other_breakpoints();
 334         use INIT_SAL() macro to zero-out new sal structures;
 335         make resolve_sal_pc() fix up the sal's section as well as its pc;
 336         match on section + pc in clear_command() and delete_breakpoint();
 337         account for overlay sections in insert_breakpoints(),
 338         remove_breakpoint() and breakpoint_re_set_one();
 339         all this to support overlays where a PC is not unique.
 340         * exec.c: change xfer_memory() to handle overlay sections.
 341         * findvar.c: change read_var_value() to handle overlay sections.

 343         * infcmd.c: jump_command() warns against jumping into an overlay
 344         that's not in memory.  Also use INIT_SAL() to initialize sals.
 345         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 346         overlay state information; Also use INIT_SAL() to init sals.

 350         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 351         * maint.c: maintenance command "translate-address" supports overlays.
 352         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 353         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 354         this constitutes gdb's internal overlay mapping table.  Add macro
 355         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 356         Add function find_pc_sect_section().
 357         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 358         modify address_info() with overlay smarts; add function sym_info()
 359         to support the INFO SYMBOL command (translate address to symbol(s));
 360         modify disassemble_command() to work on unmapped overlays.
 361         * source.c: use INIT_SAL() to initialize sals.
 362         * symfile.[ch]: change generic_load() to use section's LMA address
 363         instead of VMA address, for overlay sections.
 364         Add numerous functions for finding a PC's section / overlay,
 365         translating between VMA and LMA address ranges, determining if an
 366         overlay section is mapped, etc.  Add several user commands for
 367         overlay debugging.  Add support for a "generic" form of automatically
 368         reading overlay mapping info from the inferior (based on the default
 369         (simple) overlay manager which Cygnus provides as an example).
 370         * symtab.[ch]: add functions find_pc_sect_symtab(),
 371         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 372         for lookup; modify lookup_symbol and decode_line_1() to use them;
 373         modify find_function_start_sal() to account for overlay sections;
 374         add macro INIT_SAL() for initializing struct symtab_and_line.
 375         * target.c: fix a comment in the declaration of target_ops.
