 339 Sat Apr 19 11:56:10 1997  Per Bothner  <bothner@deneb.cygnus.com>
 340
 341         * java-exp.y:  Combine TRUE and FALSE into BOOLEAN_LITERAL.
 342         (Avoids name clash with broken AIX header files.)
 343

 345
 346         * serial.c (serial_log_command):  Fix fputs_unfiltered calls.
 347
 348         * config/powerpc/tm-ppc-aix4.h, config/rs6000/tm-rs6000-aix4.h
 349         (DONT_RELOCATE_SYMFILE_OBJFILE):  Removed.

 353         tstart and dstart with section VMA.
 354         * rs6000-nat.c (vmap_symtab):  Relocate relative to the VMA in the
 355         object file.
 356         (vmap_ldinfo, xcoff_relocate_core):  Adjust tstart by section offset
 357         of the text section, remove DONT_RELOCATE_SYMFILE_OBJFILE hack.
 358         (vmap_exec):  Relocate relative to the VMA in the object file,
 359         relocate .bss section as well.
 360         (xcoff_relocate_core):  No longer adjust section addresses by VMA.
 361         * rs6000-tdep.c (find_toc_address):  Change type of tocbase
 362         to CORE_ADDR.
 363         * xcoffread.c (secnum_to_bfd_section):  New routine to get
 364         BFD section from CS section number.
 365         (scan_xcoff_symtab):  Make toc_offset section relative.
 366
 367         * symtab.c (total_number_of_methods):  Avoid core dump if
 368         baseclass type is still undefined.
 369
 370 Fri Apr 18 17:25:10 1997  Stu Grossman  (grossman@critters.cygnus.com)
 371
 372         * Makefile.in (SUBDIRS):  Add mswin so that make cleanup cleans up
 373         that directory.
 374         * defs.h utils.c (error warning):  Make message be const.
 375         * main.c (fputs_unfiltered):  Only send gdb_stdout and gdb_stderr
 376         to hook.  Otherwise send it to fputs.
 377         * monitor.c monitor.h (monitor_get_dev_name):  New function.  Does
 378         the obvious.
 379         * remote-e7000.c:  Remove debugify stuff.  Change printf, fprintf
 380         to _filtered forms to make output appear in GUIs.  Replace all
 381         uses of SERIAL_READCHAR with readchar, which has better error
 382         checking.
 383         * (e7000_parse_device):  Add prototype.
 384         (readchar):  Improve doc.  Handle random serial errors.
 385         (expect):  Disable notice_quit code.  It's busted.  Remove
 386         serial error handling (it's now handled in readchar).  Remove
 387         remote_debug echoing.  That's handled in readchar as well.
 388         (e7000_parse_device):  Remove serial_flag arg.  It's not
 389         necessary.
 390         (e7000_open):  Split into two pieces.  Second part is
 391         e7000_start_remote, and is error protected.  Now, when we connect
 392         to the target, we setup the initial frame and registers so that
 393         the user gets an immediate indication of where the target is.
 394         (gch):  Remove debug output.  That's handled by readchar.
 395         (e7000_read_inferior_memory):  Handle errors better.
 396         (_initialize_remote_e7000):  Get rid of `<xxx>' things from
 397         command names.  They show up when doing completion and confuse
 398         things horribly.
 399         * ser-e7kpc.c: Get rid of the DLL's since we can access the device
 400         directly from Win32s and Win95.  Get rid of debugify crud.
 401         * serial.c:  Remove debugify cruft.
 402         * (serial_logchar serial_log_command serial_write serial_readchar
 403         serial_send_break serial_close):  Merge common functionality into
 404         serial_logchar.  Clean up rest of routines.
 405         * sparclet-rom.c:  Disembowel.  Leave only download routine.
 406         Download routine now switches to remote target automatically.
 407         * top.c (disconnect):  Only define if SIGHUP is defined.  Cleans
 408         up MSVC/Win32 problem.
 409         * utils.c (gdb_flush):  Don't call hook unless it's for gdb_stdout
 410         or gdb_stderr.
 411         * config/sh/tm-sh.h:  Define TARGET_SH for WinGDB.
 412         * config/sparc/tm-sparclet.h:  Remove override for prompt.

 421         * remote-sim.c (init_callbacks): Initialize poll_quit and magic
 422         fields of gdb_callback.
 423         (gdbsim_stop): Add gdbsim_stop to list of supported client
 424         operations.
 425         (gdbsim_wait, gdbsim_resume): Move call to sim_resume into
 426         sim_wait where gdb is in a position to handle a long running
 427         function.
 428         (gdbsim_cntrl_c): New function.  Wrap the sim_resume call in a
 429         SIGINT handler.
 430         (gdb_os_poll_quit): New function. Check for a quit pending on the
 431         console.

 435
 436         * Makefile.in (install-only): Make list of gdbtcl files to install
 437         explicit - was picking up files such as ChangeLog etc.
 438         (install-only): Don't blindly create the directory.

 470         (INSTALL_XFORM1): Remove.
 471         (install-only): Use $(program_transform_name) directly, rather
 472         than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
 473         (uninstall): Transform name.
 474

 482         * procfs.c (notice_signals): fix typo
 483
 484 Mon Apr 14 16:25:10 1997  Ian Lance Taylor  <ian@cygnus.com>
 485
 486         * gdbserver/Makefile.in (INSTALL): Change install.sh to
 487         install-sh.
 488
 489 Mon Apr 14 11:55:27 1997  Geoffrey Noer  <noer@pizza.cygnus.com>
 490
 491         * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
 492         since gcc automatically includes it
 493
 494 Thu Apr 10 13:20:53 1997  Geoffrey Noer  <noer@cygnus.com>
 495
 496         * procfs.c: Substantial (but incomplete) changes to support
 497         sysv4.2mp procfs as implemented in UnixWare 2.1.  The procinfo
 498         struct now has substructs like struct flt_ctl instead of
 499         just a fltset_t and has a ctl_fd, status_fd, as_fd, and
 500         map_fd instead of a single fd.  Non-sysv4.2mp procfs models
 501         still have the structs and multiple fds, but don't use the
 502         entire struct and the four fds all point to the same thing.
 503         We use PROCFS_USE_READ_WRITE to decide whether to talk to
 504         procfs with reads/writes or use ioctl instead.  We use
 505         HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
 506         multiple fds or not.  PROC_NAME_FMT is split out into
 507         CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
 508         STATUS_PROC_NAME_FMT.
 509
 510         (procfs_notice_signals): now a necessary wrapper around
 511         (notice_signals): which are the new guts for noticing signals
 512         (open_proc_file): gets a new flag arg used in sysv4.2mp to
 513         determine whether or not to attempt to open the ctl_fd.
 514         (procfs_read_status): new local function, reads procfs status
 515         (procfs_write_pcwstop): new local function, writes a PCWSTOP
 516         (procfs_write_pckill): new local function, writes a PCKILL
 517         (unconditionally_kill_inferior): remove signo since we now
 518         just call procfs_write_pckill().
 519         (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
 520         (proc_iterate_over_mappings): the whole function is ifdefed
 521         on UNIXWARE to keep things readable.
 522
 523         Expanded the syscall_table to include new potential sysv4.2mp
 524         members.  Note that all ifdefs of UNIXWARE should be eliminated
 525         if possible or renamed to describe what's being selected for a
 526         bit better.  Sysv4.2mp and IRIX both have SYS_sproc so the
 527         IRIX specific code now also checks it's not UNIXWARE.
 528
 529         * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
 530         HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
 531         * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
 532         "/debug/%d" as PROC_NAME_FMT used to be
 533
 534 Wed Apr  9 11:36:14 1997  Jeffrey A Law  (law@cygnus.com)
 535
 536         * mn10300-tdep.c: Almost completely rewritten based on mn10200
 537         port.
 538         * config/mn10300/tm-mn10300.h: Likewise.
 539
 540 Tue Apr  8 10:45:24 1997  Stu Grossman  (grossman@critters.cygnus.com)
 541
 542         * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}:  Remove
 543         remote-pa.o from TDEPFILES.  Nobody uses it, and besides, it's a
 544         lousy out-of-date clone of remote.c.
 545
 546 Fri Apr  4 08:21:21 1997  Stu Grossman  (grossman@critters.cygnus.com)
 547
 548         * remote.c:  Fix problems realized while showering.
 549         * (hexnumlen):  Add prototype.  Use max, not min.
 550         * (remote_write_bytes remote_read_bytes):  Fix max packet size
 551         calculations to properly account for packet overhead.  Also handle
 552         (probably rare) case where remote_register_buf_size isn't set.
 553
 554         * remote.c:  Fix doc for `C' and `S' commands to indicate full
 555         address.
 556         * (remote_ops extended_remote_ops remote_desc remote_write_size):
 557         Make static.
 558         * (remote_fetch_registers remote_write_bytes remote_read_bytes):
 559         Record size of response to fetch registers command, use this to
 560         limit size of memory read and write commands.
 561         * (push_remote_target):  New function to make it possible to have
 562         another target switch to the remote target.
 563         * target.h:  Add prototype for push_remote_target.
 564         * sh-tdep.c (sh_frame_find_saved_regs):  Fix sign extension bugs
 565         for hosts which default to unsigned chars (such as SGI's).
 566         * (_initialize_sh_tdep):  Don't set remote_write_size.  It's now
 567         handled automatically in remote.c.
 568
 569 Thu Apr  3 15:10:30 1997  Michael Snyder  <msnyder@cleaver.cygnus.com>
 570
 571         * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
 572         find_pc_sect_function(), find_pc_sect_partial_function(): new
 573         functions for debugging overlays; pc without section is ambiguous.
 574         * breakpoint.[ch]: add section pointer to breakpoint struct;
 575         add section argument to check_duplicates(); check section as well
 576         as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
 577         breakpoint_thread_match(), bpstat_stop_status()];
 578         add section argument to describe_other_breakpoints();
 579         use INIT_SAL() macro to zero-out new sal structures;
 580         make resolve_sal_pc() fix up the sal's section as well as its pc;
 581         match on section + pc in clear_command() and delete_breakpoint();
 582         account for overlay sections in insert_breakpoints(),
 583         remove_breakpoint() and breakpoint_re_set_one();
 584         all this to support overlays where a PC is not unique.
 585         * exec.c: change xfer_memory() to handle overlay sections.
 586         * findvar.c: change read_var_value() to handle overlay sections.
 587         * frame.h: declaration for block_for_pc_sect() [blockframe.c].
 588         * infcmd.c: jump_command() warns against jumping into an overlay
 589         that's not in memory.  Also use INIT_SAL() to initialize sals.
 590         * infrun.c: wait_for_inferior() sets a flag to invalidate cached
 591         overlay state information; Also use INIT_SAL() to init sals.
 592         * m32r-rom.c: modify load routines to use LMA instead of VMA.
 593         * m32r-stub.c: mask exit value down to 8 bits; screen out any
 594         memory read/writes in the range 600000 to a00000, and ff680000
 595         to ff800000 (hangs because nothing is mapped there); fix strcpy().
 596         * maint.c: maintenance command "translate-address" supports overlays.
 597         * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
 598         * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
 599         this constitutes gdb's internal overlay mapping table.  Add macro
 600         ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
 601         Add function find_pc_sect_section().
 602         * printcmd.c: modify print_address_symbolic() with overlay smarts;
 603         modify address_info() with overlay smarts; add function sym_info()
 604         to support the INFO SYMBOL command (translate address to symbol(s));
 605         modify disassemble_command() to work on unmapped overlays.
 606         * source.c: use INIT_SAL() to initialize sals.
 607         * symfile.[ch]: change generic_load() to use section's LMA address
 608         instead of VMA address, for overlay sections.
 609         Add numerous functions for finding a PC's section / overlay,
 610         translating between VMA and LMA address ranges, determining if an
 611         overlay section is mapped, etc.  Add several user commands for
 612         overlay debugging.  Add support for a "generic" form of automatically
 613         reading overlay mapping info from the inferior (based on the default
 614         (simple) overlay manager which Cygnus provides as an example).
 615         * symtab.[ch]: add functions find_pc_sect_symtab(),
 616         find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
 617         for lookup; modify lookup_symbol and decode_line_1() to use them;
 618         modify find_function_start_sal() to account for overlay sections;
 619         add macro INIT_SAL() for initializing struct symtab_and_line.
 620         * target.c: fix a comment in the declaration of target_ops.

 629         new code to skip over MIPS16 thunks.
 630         (mips_frame_chain): Skip over MIPS16 thunks.
 631         * config/mips/tm-mips.h (mips_in_call_stub, mips_in_return_stub,
 632         mips_skip_stub, mips_ignore_helper): Declare.
 633         (IN_SOLIB_CALL_TRAMPOLINE, IN_SOLIB_RETURN_TRAMPOLINE,
