 326         (e7000_parse_device):  Remove serial_flag arg.  It's not
 327         necessary.
 328         (e7000_open):  Split into two pieces.  Second part is
 329         e7000_start_remote, and is error protected.  Now, when we connect
 330         to the target, we setup the initial frame and registers so that
 331         the user gets an immediate indication of where the target is.
 332         (gch):  Remove debug output.  That's handled by readchar.
 333         (e7000_read_inferior_memory):  Handle errors better.
 334         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
 335         command names.  They show up when doing completion and confuse
 336         things horribly.
 337         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
 338         directly from Win32s and Win95.  Get rid of debugify crud.
 339         * serial.c:  Remove debugify cruft.
 340         * (serial_logchar serial_log_command serial_write serial_readchar
 341         serial_send_break serial_close):  Merge common functionality into
 342         serial_logchar.  Clean up rest of routines.
 343         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 344         Download routine now switches to remote target automatically.
 345         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 346         up MSVC/Win32 problem.
 347         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
 348         or gdb_stderr.

 428

 430         since gcc automatically includes it
 431
 432 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 433
 434         * procfs.c: Substantial (but incomplete) changes to support
 435         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 436         struct now has substructs like struct flt_ctl instead of
 437         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 438         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 439         still have the structs and multiple fds, but don't use the
 440         entire struct and the four fds all point to the same thing.
 441         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 442         procfs with reads/writes or use ioctl instead.  We use
 443         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 444         multiple fds or not.  PROC_NAME_FMT is split out into
 445         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 446         STATUS_PROC_NAME_FMT.
 447
 448         (procfs_notice_signals): now a necessary wrapper around
 449         (notice_signals): which are the new guts for noticing signals
 450         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 451         determine whether or not to attempt to open the ctl_fd.
 452         (procfs_read_status): new local function, reads procfs status
 453         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 454         (procfs_write_pckill): new local function, writes a PCKILL
 455         (unconditionally_kill_inferior): remove signo since we now
 456         just call procfs_write_pckill().
 457         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 458         (proc_iterate_over_mappings): the whole function is ifdefed
 459         on UNIXWARE to keep things readable.
 460
 461         Expanded the syscall_table to include new potential sysv4.2mp
 462         members.  Note that all ifdefs of UNIXWARE should be eliminated
 463         if possible or renamed to describe what's being selected for a
 464         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 465         IRIX specific code now also checks it's not UNIXWARE.
 466
 467         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 468         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 469         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 470         "/debug/%d" as PROC_NAME_FMT used to be
 471
 472 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 473
 474         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 475         port.
 476         * config/mn10300/tm-mn10300.h: Likewise.

 478 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 479
 480         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 481         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 482         lousy out-of-date clone of remote.c.
 483
 484 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 485
 486         * remote.c:  Fix problems realized while showering.
 487         * (hexnumlen):  Add prototype.  Use max, not min.
 488         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 489         calculations to properly account for packet overhead.  Also handle
 490         (probably rare) case where remote_register_buf_size isn't set.
 491
 492         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 493         address.
 494         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 495         Make static.
 496         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 497         Record size of response to fetch registers command, use this to
 498         limit size of memory read and write commands.
 499         * (push_remote_target):  New function to make it possible to have
 500         another target switch to the remote target.
 501         * target.h:  Add prototype for push_remote_target.
 502         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 503         for hosts which default to unsigned chars (such as SGI's).
 504         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 505         handled automatically in remote.c.

 507 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 508
 509         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 510         find_pc_sect_function(), find_pc_sect_partial_function(): new
 511         functions for debugging overlays; pc without section is ambiguous.
 512         * breakpoint.[ch]: add section pointer to breakpoint struct;
 513         add section argument to check_duplicates(); check section as well
 514         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 515         breakpoint_thread_match(), bpstat_stop_status()];
 516         add section argument to describe_other_breakpoints();
 517         use INIT_SAL() macro to zero-out new sal structures;
 518         make resolve_sal_pc() fix up the sal's section as well as its pc;
 519         match on section + pc in clear_command() and delete_breakpoint();
 520         account for overlay sections in insert_breakpoints(),
 521         remove_breakpoint() and breakpoint_re_set_one();
 522         all this to support overlays where a PC is not unique.
 523         * exec.c: change xfer_memory() to handle overlay sections.
 524         * findvar.c: change read_var_value() to handle overlay sections.
 525         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 526         * infcmd.c: jump_command() warns against jumping into an overlay
 527         that's not in memory.  Also use INIT_SAL() to initialize sals.
 528         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 529         overlay state information; Also use INIT_SAL() to init sals.
 530         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 531         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 532         memory read/writes in the range 600000 to a00000, and ff680000
 533         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 534         * maint.c: maintenance command "translate-address" supports overlays.
 535         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 536         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 537         this constitutes gdb's internal overlay mapping table.  Add macro
 538         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 539         Add function find_pc_sect_section().
 540         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 541         modify address_info() with overlay smarts; add function sym_info()
 542         to support the INFO SYMBOL command (translate address to symbol(s));
 543         modify disassemble_command() to work on unmapped overlays.
 544         * source.c: use INIT_SAL() to initialize sals.
 545         * symfile.[ch]: change generic_load() to use section's LMA address
 546         instead of VMA address, for overlay sections.
 547         Add numerous functions for finding a PC's section / overlay,
 548         translating between VMA and LMA address ranges, determining if an
 549         overlay section is mapped, etc.  Add several user commands for
 550         overlay debugging.  Add support for a "generic" form of automatically
 551         reading overlay mapping info from the inferior (based on the default
 552         (simple) overlay manager which Cygnus provides as an example).
 553         * symtab.[ch]: add functions find_pc_sect_symtab(),
 554         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 555         for lookup; modify lookup_symbol and decode_line_1() to use them;
 556         modify find_function_start_sal() to account for overlay sections;
 557         add macro INIT_SAL() for initializing struct symtab_and_line.
 558         * target.c: fix a comment in the declaration of target_ops.

 568         (mips_frame_chain): Skip over MIPS16 thunks.
 569         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,

1313
1314         * blockframe.c (frameless_look_for_prologue):  Mark frames
1315         with a zero PC as frameless to improve backtraces from core dumps
1316         caused by dereferencing a NULL function pointer.

1319
1320         * config/mn10300/tm-mn10300.h: fix BREAKPOINT definition.

1322 Tue Jan 14 16:01:06 1997  Geoffrey Noer  <noer@cygnus.com>
1323
1324         * mn10300-tdep.c: made a lot more generic, ripping out code
1325         from copied target (no more mn10300_scan_prologue,
1326         init_extra_frame_info, and mn10300_fix_call_dummy calls)
1327         * config/mn10300/tm-mn10300.h: undefine INIT_EXTRA_FRAME_INFO
1328         and INIT_FRAME_PC macros

1331
1332         * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
1333         FP_REGISTER_BYTES to compute offsets into the saved frame,
1334         since it fails for SPARC targets configured without any
1335         FP regs.  Instead, use DUMMY_STACK_REG_BUF_SIZE.

1337 Mon Jan  6 11:15:14 1997  Stu Grossman  (grossman@critters.cygnus.com)
1338
1339         * symtab.c (fixup_symbol_section):  Handle NULL symbols without
1340         crashing.
1341
1342 Fri Jan  3 12:08:16 1997  Stu Grossman  (grossman@critters.cygnus.com)
1343
1344         * Makefile.in configure configure.in:  Remove ENABLE_CLIBS,
1345         ENABLE_OBS, and THREAD_DB_OBS.  These are consolidated into LIBS
1346         and CONFIG_OBS.
1347         * configure configure.in:  Clean up test cases around thread support.
1348 start-sanitize-v850
1349         * configure.tgt (v850-*-*):  Include v850ice.o and v850.lib if
1350         host is Windows.
1351 end-sanitize-v850
1352         * c-valprint.c ch-valprint.c cp-valprint.c eval.c expprint.c
1353         printcmd.c valops.c value.h values.c:  Add bfd_section arg to
1354         value_at and value_at_lazy.
1355         * coffread.c dbxread.c elfread.c mdebugread.c minsyms.c symtab.h:
1356         Add bfd_section arg to prim_record_minimal_symbol_and_info.
1357         * corefile.c gdbcore.h printcmd.c valops.c:  Use read_memory_section
1358         instead of read_memory.  It takes a bfd_section arg.
1359         * coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h:  Remove
1360         unnecessary cast for assignment of struct dbx_symfile_info.
1361         Struct objfile now uses a real pointer instead of PTR for this
1362         element.
1363         * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
1364         text, data and bss into dbx_symfile_info.
1365         * exec.c (xfer_memory):  Handle transfers for user-specified
1366         sections.
1367         * findvar.c (read_var_value locate_var_value):  Copy bfd section
1368         from the symbol to the value.
1369         * gdb-stabs.h:  Add section pointers for text, data and bss
1370         sections.
1371         * maint.c (translate address command):  Add test code for overlay
1372         address translation.
1373         * printcmd.c (do_examine do_one_display):  Now takes a bfd section
1374         arg.
1375         * (print_formatted x_command):  Record current section along with
1376         current address for repeated commands.
1377         * sparc-nat.c (fetch_inferior_registers):  Change
1378         target_xfer_memory to target_{read write}_memory to allow changes
1379         to target_xfer_memory interface for section info.
1380         * symmisc.c (dump_msymbols print_symbol):  Print section
1381         assocaited with symbol.
1382         * symtab.c (fixup_symbol_section):  New routine to
1383         add section info to symbols returned by lookup_symbol.
1384         * symtab.h (struct general_symbol_info):  Add bfd section to
1385         symbols.
1386         * target.c target.h (target_xfer_memory):  Add bfd section to
1387         args.
1388         * (target_read_memory_section):  New routine to read data from a
1389         specific section.
1390         * (target_memory_bfd_section):  New global variable to pass bfd
1391         section in to targets.
1392         * valarith.c (value_add value_addr value_array):  Preserve bfd
1393         section when computing new value.
1394         * value.h (struct value):  Add bfd section to values.
1395         * values.c (allocate_value value_copy):  Initialize/preserve bfd
1396         section.
1397         * (unpack_double):  Clean up _MSC_VER conditionals to remove
1398         duplicate code.
1399 start-sanitize-v850
1400         * v850ice.c:  New module to support communication with NEC's
1401         PC-based ICE.
1402         * config/v850/tm-v850.h (REGISTER_NAMES):  Replace sp, gp, fp, and
1403         ep names with rxx names.  sp and fp are renamed via a different
1404         mechanism.

1408
1409         * mn10300-tdep.c (mn10300_push_arguments): rewrote,
1410         also removed code elsewhere that made use of RP_REGNUM.
1411         * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
1412         ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
1413         arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
1414         EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
