[platform/upstream/binutils.git] / gdb / ChangeLog-1990

Fri Dec 28 00:13:42 1990  John Gilmore  (gnu at cygint)

        Further stabilization for the Intel 960.

        * Makefile.dist: Parameterize the location of the "include"
        and "bfd" directories, as well as "getopt".  Add symfile.c.
        Link in both dbxread and coffread.  Fix up "make depend" to
        rewack the locations of include, bfd, and getopt in its output.

        * README:  Document moving include files, improve some of
        the other doc.

        * coffread.c:  Move common code out to symfile.c.  Change
        symbol_file_command style interface to use new *_symfile_init
        and *_symfile_read interface under BFD.  Use BFD internal
        info to locate line table, symbols, etc.

        * core.c (core_fetch_registers):  Rename to get_core_registers
        to avoid confusion with fetch_core_registers.
        (register_addr):  Move to coredep.c, which is already machine
        dependent.  This leaves core.c pretty clean of dependencies.

        * coredep.c (register_addr):  Accept this routine from core.c.

        * dbxread.c: Move common code (with coffread.c, etc) into new
        symfile.c.  Each psymtab now contains a pointer to the
        format-dependent function that knows how to read it in.  Make
        some things static.  
        (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
        (process_one_symbol): Add code to complain about a "compiler bug
        we muzzle here", if we actually see it.

        * eval.c (evaluate_subexp):  Insert missing "break" statements
        in code that determines whether a variable is an lvalue in
        memory, register, or whatever.  I detected this via a compiler
        bug in which it *almost* mashed out the whole switch statement.

        * gdb-int.texinfo:  Add minor sections on configuring gdb for
        release, and about the README file.

        * infcmd.c (registers_info):  Fix formatting somewhat.  Still
        not as pretty as before, but it handles byte swapping.

        * remote-nindy.c: If data cache routines are interrupted while
        waiting for the remote end, be sure that any uninitialized cache
        blocks are on the free list, not on the valid list!

        * symfile.h: Flesh out this header file with all the various
        routines and variables that have been merged in from dbxread.c
        coffread.c, and symtab.c to symfile.c.

        * symfile.c: New file, containing code common to dbxread.c,
        coffread.c, and some code from symtab.c.  All generic code for
        reading symbol files should be in here now.
        (unrecord_misc_function):  Remove unused function.

        * symtab.h:  Remove file-reading things to symfile.h.

        * symtab.c:  Remove file-reading things to symfile.c.

        * tm-i960.h:  Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
        to decode i960 fault types.

        * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
        target.c: Change type of the "resume" function from int to void,
        since its result was never used.

Sat Dec 22 02:51:40 1990  John Gilmore  (gnu at cygint)

        * main.c:  Replace "stupid" with "caution"; you now "set caution
        on or off".

        * printcmd.c (print_scalar_formatted):  Fix typo in 'g' format

        * infcmd.c (do_registers_info):  Call val_print to deal with the
        byte order of the registers being printed.  FIXME, this makes
        the formatting of the output uglier.

        * infcmd.c (wait_for_inferior):  If PRINT_RANDOM_SIGNAL is
        defined, call it for signals the debugger doesn't itself use.
        The i960 uses this for more detailed fault information.

        * remote.c (remote_open):  If arg is null, print help rather than
        dumping core.

        * sparc-xdep.c (register_valid):  Avoid declaring size, since
        various modules will think of various sizes depending on the
        architecture of their tm-file.  FIXME, we need protection against
        actually entering one of those modules, which would clobber
        storage if not for the target architecture compiled into gdb.

        * stack.c (up_command, down_command):  Always print the frame
        you arrive at.
        (up_silently_command, down_silently_command):  New commands
        for use in scripts.

        * i960-pinsn.c (reg), i960-tdep.c:  Lint.

        * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
        more parameters than it used to.

        * findvar.c (registers):  Increase slop to 256 bytes, which should
        protect us against even most RISC machines with large register
        sets.
        (locate_var_value):  Move declaration inside related ifdef.

        * remote-nindy.c ():  Use TIOCSETN rather than TIOCSETP
        throughout, to avoid throwing away buffered input from the board.
        (nindy_wait):  Supply_register takes addr_of_value, not value.
        (i960_print_fault):  Renamed from i80960_fault.
        (nindy_fetch_registers):  Avoid have_regs stuff, just get them.
        (nindy_store_registers):  Avoid regs_changed stuff, just stuff
        them.
        (nindy_create_inferior):  Don't bother to write PC_REGNUM since
        we can set the PC in the call to proceed().  Unpush nindy_ops
        before pushing it on top, to avoid message to user.  Eliminate
        commentary from Unix machines that just misleads here.
        (reset_command):  Fix error message to suggest target command.
        
Wed Dec 19 11:03:56 1990  John Gilmore  (gnu at cygint)

        Release 3.92.5 as frozen.

        Stabilize the merged release...with help from lint, Saber C,
        gcc -W, etc.

        Everywhere:  Add include files needed to declare return types
        of functions called.

        * gdb.texinfo:  Roland Pesch is documenting gdb, glory be!

        * breakpoint.h:  Add undeclared breakpoint functions, and some
        functions for display handling since I couldn't think of a better
        .h to put them in.

        * breakpoint.c (insert_breakpoints):  Make code for disabling
        shared library bkpts more likely to work.  It's used when we
        rerun a program and stop before the shared library has been
        mapped in.
        (breakpoint_cond_eval, bpstat_stop_status):  Pass arg as int,
        cast from pointer, so it squeezes through catch_errors.
        (bpstat_stop_status):  Fix logic broken some time ago.  We now
        always create a bpstat if the stop address matches a breakpoint,
        even if we don't stop there -- just like the old code used to do
        before I got my fingers into it (sigh).
        (breakpoint_1):  Print "ignore count" after "stop only if"
        condition, since that's how it actually works.
        (mention):  Handle watchpoints as well as breakpoints.
        (watch_command):  use set_raw_breakpoint and mention to do most 
        of the work (and initialize all the fields!).  Only pass one
        arg to parse_c_expression, since that's all it takes.

        * command.c (not_just_help_class_command):  Rename arg to args
        since we ignore "unused argument" warnings on vars named "args".
        inflow.c (child_terminal_info):  ditto.
        infptrace.c (kill_inferior):  ditto
        main.c (catch_errors, version_info, quit_command, pwd_command,
        source_command, dump_me_command, editing_info,
        set_history_size_command, set_history, show_history,
        set_verbose): ditto
        stack.c (locals_info):  ditto
        target.c (target_files_info):  ditto
        valprint.c (set_input_radix, set_output_radix):  ditto

        * core.c:  Remove old variables for handling core and exec file
        sections (data_start, data_end, stack_start, stack_end,
        reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
        text_end, exec_data_start, exec_data_end, text_offset,
        exec_data_offset, data_offset, stack_offset).  They're
        superseded the more general build_section_table and
        xfer_memory.
        (get_exec_file):  Mention the `file' command.
        (read_memory_check):  Rename to memory_error, and only call it
        in the case of an actual error.
        (read_memory, write_memory):  call memory_error.
        (core_fetch_registers):  Register section name is ".reg".

        coredep.c:  Remove a bunch of crud now that all this file does
        is pull the registers out of a core file.
        (fetch_core_registers):  Rewrite to actually work, I hope.

        dbxread.c:  Use a.out.gnu.h, not system a.out, now.
        Replace index() with strchr().  Remove all the pre-BFD macro
        definitions for accessing the symbol file.
        (struct dbx_symfile_info):  Encapsulate the information that
        dbx_symfile_init needs to pass to dbx_symfile_read in this
        struct.

        (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
        dbx_symfile_discard): Rearrange symbol file reading to divide
        the format-specific part from the format-independent part,
        leaving the format-independent part such as file name expansion
        and opening in symtab.c.  This replaces
        partial_symbol_file_open and partial_symbol_file_read.
        Symbol_file_read, add_file, add_file_target_command,
        add_file_addr_command move to symtab.c.  Pass an explicit
        "mainline" flag for when reading the main symbol table, rather
        than relying on the offset address to be zero or nonzero.

        (dbx_symfile_read): Don't allow void *'s to be printed as
        typedefs.
        (SWAP_SYMBOL):  Use bfd routines to byte-swap the symbols.
        (ADD_PSYMBOL_TO_LIST):  Make the "function call rather than
        macro" debug version really work.
        (read_dbx_symtab):  Remove unref'd parameter inclink.
        Avoid swapping N_SLINE symbols, for speed.
        Merge N_TEXT!N_EXT case with the other external symbol
        definitions' case. Add comments.
        (start_psymtab):  Allocate the symfile name in the psymtab on
        the psymbol_obstack, rather than using the caller's storage.
        (end_psymtab): Only allocate a dependencies list if there are
        more than zero.
        (psymtab_to_symtab_2):  Use BFD when reopening file to read
        its symbols for real.
        (read_struct_type):  Add FIXME comments where it needs work
        for C++ bogosity.
        (read_huge_number):  Add FIXME about overflows.
        (read_range_type):  Add FIXME about comparing a long to 1<<32.

        * coffread.c:  Minor changes to move things closer to the new
        regime with symtab.c and dbxread.c   Major work is still needed
        here.

        * exec.c (exec_file_command):  Remove old variables (see core.c
        above).
        (xfer_memory): If memory transfer is right at the end of a
        section, don't lose.

        * findvar.c (get_saved_register):  If value is in a real
        register, LVAL is lval_register, not lval_memory.

        frame.h:  Declare print_sel_frame and record_selected_frame.

        gdb-int.texinfo:  New file, for GDB internals documentation.
        Very simple, unformatted doc of cleanups is there for now.

        gdbcore.h:  Remove obsolete variables that described a.out
        section addresses and offsets.  (See core.c above.)
        Declare fetch_core_registers and registers_fetched.

        getopt.c:  Declare char *alloca(); even on SPARC.

        infcmd.c (run_command):  Call target_kill rather than
        kill_inferior. 
        (step_command, next_command, stepi_command, nexti_command):
        Declare from_tty parameter even though we don't use it.
        (run_stack_dummy):  argument BUFFER is a char array, not
        a pointer to REGISTER_TYPE.
        (finish_command):  using_struct_return needed a value *, 
        not a struct symbol *.

        * infptrace.c (child_xfer_memory):  To avoid dependency on
        where sections are in memory, try PT_WRITE_D and if that fails,
        try PT_WRITE_I.  Most Unixes don't care which you use.

        * infrun.c (step_resume_break_shadow):  Change to array to
        match other breakpoint shadow storage.
        (clear_proceed_status):  Pass address of bpstat to
        bpstat_clear, not the bpstat itself.
        (child_create_inferior):  FIXME comment about if the child
        exits.
        (start_inferior):  Remove old function.
        (child_open):  Use target_kill rather than kill_inferior.
        (wait_for_inferior):  Ditto.
        (insert_step_breakpoint, remote_step_breakpoint):  Use
        new step_resume_break_shadow.

        * inftarg.c (child_wait):  If all child processes die,
        pretend that the one being waited for exited with signal 42.

        * main.c (command_line_input):  When scanning for comments,
        don't coredump on unclosed quotes.
        (quit_command):  Use target_kill rther than kill_inferior.
        (_initialize_main):  Rename class_user from "user" to
        "user-defined".

        * printcmd.c (print_command_1):  Initialize "fmt" if no format
        is specified by the user.
        (print_frame_args):  Only add to args_printed if we are
        actually fetching args from the stack (avoiding undefined
        arg_size).
        (_initialize_printcmd):  Remove bogus \{ from string.

        * remote-eb.c (eb_open):  Avoid coredump on no argument.

        * remote-nindy.c:  Bring out of Intel environment into new
        target environment.  Remove all conditional compilation on
        I80960.  Massive hacking throughout.
        (nindy_xfer_inferior_memory):  New routine stolen from
        infptrace.c.
        (nindy_create_inferior):  New routine pieced together, probably
        not quite working yet.
        (nindy_ops):  New target_ops struct for nindy.

        * remote-vx.c:  Use write_memory rather than target_write_memory
        to get error checking.
        (vx_add_file_command, vx_open): Use symbol_file_add rather than
        add_file.
        (vx_create_inferior):  Use target_terminal_ours...

        * signame.c (_initialize_signame):  Always initialize, since
        we need the table for things other than psignal.
        
        * solib.c (solib_add):  Use symbol_file_add, not add_file.
        (solib_address):  Return boolean result rather than struct
        pointer which nobody else knows the type of.

        * sparc-tdep.c, valops.c:  Use write_memory rather than
        target_write_memory, to get error checking.

        * stack.c (locals_info, catch_info, args_info,
        get_selected_block, frame_command, up_command): Use
        target_has_stack, rather than have_inferior_p or
        have_core_file_p.

        * sun3-xdep.c (fetch_core_registers):  Rewrite for new BFD regime.

        * symfile.h:  New file, defining the interface between the
        generic and object-file-specific symbol reading code.

        * symtab.c:  Move generic symbol-reading interface to symtab.c,
        from dbxread.c, coffread.c, mipsread.c, etc.  Add symtab_fns
        table to map BFD targets to symbol-reading modules in GDB.
        Change index to strchr.
        (lookup_struct_elt_type):  Use error() rather than hand-made
        simulations thereof.
        (lookup_partial_symbol):  Speedup slightly when length == 0.
        (symbol_file_add):  New function.
        (symbol_file_command):  Call it.
        (symfile_open, symfile_init):  New function.
        (add_file_target_command, add_file_addr_command): moved from
        dbxread.c.

        * target.c (target_command):  use target_kill.

        * target.h (target_files_info):  Don't declare, never called
        from outside.

        * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
        files to determine stack end address.

        * valarith.c (value_x_binop, value_x_unop): Change error message
        to be more useful.  Pass proper argument to value_struct_elt.

        * valops.c (value_assign):  FIXME comment that long long 
        bitfields will break here.

        * Makefile.dist:  Add symfile.h, remote-nindy.c, remote-eb.c.
        Update `make saber_gdb' to work better.

        * TODO:  A woman's work is never done.

        * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
        main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
        remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
        sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
        target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
        valops.c, valprint.c, exec.c:  Lint.


Wed Dec 12 23:44:15 1990  John Gilmore  (gnu at cygnus.com)

        Continuing Intel 960 port merge of GDB.

        * Makefile.dist:  Merge i960 "nindy-share" files.  Rename
        malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
        Don't ship gdb.dvi in tar file.  Link gdb with init.o, not init.c.
        Wack over "make depend" so it handles files in subdirectories
        vx-share, nindy-share, bfd, and in the current directory.

        * blockframe.c (get_prev_frame_info):  Remove fatal error
        if stack not defined.

        * core.c (core_open, core_detach):  New functions that handle
        the old "core-file" command as "target core" and "detach" instead.
        (core_file_command):  Call them.
        (core_xfer_memory):  Use common routine xfer_memory.

        * dbxread.c:  Include a.out.gnu.h, not system a.out.h.
        dbxread now uses bfd for everything but symbol reading itself.
        BFD internals are used to drag out the relevant file offsets.
        (partial_symbol_file_open):  Change args all around for BFD.

        * symtab.c: Rename "value" to "val" everywhere, so we can
        #include "value.h".
        (symbol_file_command):  New command, moved from dbxread.c
        and coffread.c.  It uses BFD to read the file, then vectors
        based on its type, to dbx or coff symbol readers.
        * symtab.h:  Extern a few vars for symbol_file_command.

        * target.h:  Breakpoint takes a char * save area, not a char **.

        * valprint.c (val_print):  When unpacking bitfields, offset
        the address in gdb of the value, if it is declared with a shorter
        type.  Remove the last "runtime kludge test" of host byte order.

        * utils.c:  Remove old my_bfd_read routine.

        * stack.c (frame_info):  Use target_has_stack.  Print program counter
        register's actual name rather than "pc", since it's called the
        "ip" (instruction pointer) on the i960 (sigh).

        * target.c (target_command):  Add command for selecting a target
        type and calling its open routine.  This is used for initiating
        communication with a particular target, in a generic way.

        * tm-i960.h:  Update for modern gdb.  Remove semicolons from
        various macros.  Handle reading struct return convention, and
        error-out attempts to return structs with the "return" command.
        Be sure gdb doesn't think we know how to call functions in the
        inferior.

        * i960-tdep.c:  Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
        to i960_xxx in lower case.
        (arg_address):  Circumvent errors due to LOC_ARG_BLOCK
        not being defined yet.

        * remote.c (remote_open):  Call start_remote to initialize 
        wait_for_inferior during open.
        (remote_xfer_inferior_memory):  Return length written rather
        than errno value.

        * remote-vx.c (target_command -> vx_open):  Use new generic
        target command.
        * remote-eb.c, inftarg.c, exec.c: ditto.

        * infrun.c:  Fix comments.
        (attach_program -> child_open):  Use new generic target command.
        (wait_for_inferior):  Clear saved register values before target_wait,
        so target_wait can set some of them if convenient.

        * infptrace.c (fetch_inferior_registers, store_inferior_registers):
        Return success indicator, not void.
        (child_xfer_memory):  Avoid fetching initial word if we'll
        overwrite it anyway.

        * infcmd.c (attach_command):  Use new generic target open routine.
        (_initialize_infcmd):  Update doc on attach and detach commands.
        (do_registers_info):  Merge in a byte-order problem as a FIXME
        comment.

        * findvar.c (find_saved_register):  Avoid problem in current frame.
        (read_relative_register):  Ditto.
        (write_register):  Convert byte order on the way out.

        * exec.c (file_command):  Add.
        (add_to_section_table, exec_command):  Use new bfd_map_over_sections.
        (xfer_memory):  Common function between core_xfer_memory and
        exec_xfer_memory.
        (exec_xfer_memory):  Use it.

        * pn-opcode.h:  Document that a "PN" is a Gould PowerNode.

        * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
        valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
        infcmd.c, i960-pinsn.c, eval.c, defs.h:  lint and gcc -Wall.

Sun Dec  2 16:45:06 1990  John Gilmore  (gnu at cygnus.com)

        Merge Intel 960 port of gdb, continuing...

        * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
        symbol_file_command):  Pass from_tty arg to hush 'em up.

        * coffread.c (symbol_file_command):  Avoid output if from_tty != 1.
        Add magic numbers for 960 COFF format.

Fri Nov 30 09:18:20 1990  John Gilmore  (gnu at cygnus.com)

        Merge Intel 960 port of gdb, from Intel "1.2" release.

        CHANGE_LOG entries from their port, which was based on
        gdb+-2.8.0:

    Thu Sep  6 11:02:22 PDT 1990
        Remove temp file if download is interrupted.

    Wed Aug  1 09:08:33 PDT 1990
        Now uses binary protocol to talk to NINDY.
        Old hex protocol (NINDY 2.13 and older) supported with -O switch.
        Times out after 5 seconds when trying to talk to NINDY.

    Tue May 29 12:54:49 PDT 1990
        Added variable baud rate (-b switch).
        Source code reorganization.

    Thu Apr 26 11:09:55 PDT 1990
        More cleanup of batch mode;  specifically, execute "-s", "-e", and
        "-se" switches as soon as they are encountered on the invocation line.

    Fri Apr 20 13:47:15 PDT 1990
        Add -brk switch.

    Thu Apr 19 09:54:28 PDT 1990
        Add 'reset' command.

    Wed Apr 18 09:48:07 PDT 1990
        After opening remote tty, wait for 1 second to go by without input
        from it before trying to talk to NINDY (fixes problems with the
        Heurikon HK80/V960E).

    Mon Apr  4 16:33:05 PDT 1990
        Some output was not being suppressed in 'batch' mode.

    Thu Mar 22 15:31:11 PST 1990
        Ask user if old symbol table should be deleted when new file is
        downloaded.

        Allow user to run a program downloaded before gdb960 was brought up.

        Correct "exec-file" help message for i80960 context.

        Correct bug in calculating user space address:  could occasionally
        corrupt user program.

        Make sure to zero low-order bits in rip's because of bug in 960CA
        A-step part:  could cause operation faults when "next"ing across
        a function call.

        Correct bug that made it impossible to get source line numbers for
        code loaded at addresses higher than 0x7fffffff.

    Wed Jan 10 12:43:22 PST 1990
        Open remote tty for exclusive use.

    Fri Jan  5 12:14:42 PST 1990
        Correct disassembly (CA manual was right after all):
        opcode for sysctl is 0x659

    Mon Oct 23 12:03:04 PDT 1989
        Use G960BASE and G960BIN environment variables to find 'sx' utility.

    Mon Oct 16 14:15:09 PDT 1989
        "sfr0"-"sfr31" should have been named "sf0"-"sf31"

    Mon Oct  2 15:56:31 PDT 1989

        Added 960CA disassembly support.

        To simplify maintenance:
                - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
                        directly instead.
                - eliminated opcode.h: incorporates tables into i960-pinsn.c
                - moved 960-specific routines from i960-pinsn.c to i960-md.c
                - made disassembly interface identical to that in gdmp960.



Wed Nov 28 21:32:48 1990  John Gilmore  (gnu at cygint)

        * target.h: Allow targets to stack.  Add target_has_memory,
        _registers, etc.  Restructure memory access and "info files"
        to walk the target stack.
        * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
        target.c:  Change tables to match target.h.
        * inflow.c (child_mourn_inferior):  pop child_ops.
        (generic_mourn_inferior):  Use new has_stack flag.
        * infptrace.c (child_xfer_memory): New memory regime.
        * inftarg.c (child_files_info): New "info files" regime.
        * remote-eb.c: New memory regime, new info files.
        * remote-vx.c: New memory regime, new info files.  Now use
        separate targets for VxWorks attachment to machine, and 
        actually running a process under VxWorks, since one has
        stack & execution & regs and the other doesn't.
        * remote.c: New memory regime, new info files.
        * sparc-xdep.c (fetch_core-registers):  New memory regime.
        * target.c:  New routines and support for stacked targets,
        new memory regime, new info files regime.
        

        Generalize section handling for an arbitrary number of sections,
        including use of the new BFD (binary file) library.
        * gdbcore.h: Add struct section_table.
        * exec.c (build_section_table):  Iterate all sections and
        record what gdb needs to know about them.
        (exec_command):  Use it.
        (exec_xfer_memory):  Use the table.
        (exec_files_info):  Print the table.
        * core.c (core_file_command, core_xfer_memory, core_files_info):
        Likewise.       
        * source.c (find_source_lines):  Use bfd_get_mtime.
        * dbxread.c:  Quick changes to make it compile with new BFD.

        * core.c (core_fetch_registers):  Get from the ".regs" section of
        the BFD core file.
        * sparc-xdep.c (fetch_core_registers):  Use the .regs info.

        * inferior.h (attach_flag):  Export.
        * infcmd.c (run_command):  use new target_create_inferior.
        * infrun.c (child_create_inferior):  Don't return result.
        * Makefile.dist (VERSION):  3.91.4.

Fri Nov 23 28:15:38 1990  John Gilmore  (gnu at cygint)

        * breakpoint.c (bpstat_num):  Handle breakpoints which have
        since been deleted, such as temporary breakpoints.
        infcmd.c (program_info):  ditto.

        * core.c (core_file_command):  Display the frame where the core
        dump occurred.

        * main.c:  lint.

        * remote-vx.c (target_command):  Merge in target command from
        targ-vx.c.  A few other cleanups.

        * TODO, Projects:  Lots more stuff to do...

Fri Nov 23 18:15:38 1990  John Gilmore  (gnu at cygint)

        Massive changes to wall off the remote-debugging interface
        behind a function vector.  The port to handle VxWorks targets
        is also part of this.

        All files:  Replace references to renamed functions,
        remove references to remote_debugging, remove references to
        have_include_file, have_core_file in favor of target_has_stack,
        target_has_memory, etc.

        * Modularize the breakpoint interface.
        breakpoint.h (BREAKPOINT_MAX):  New define sets max length of
        a breakpoint instruction.
        breakpoint.c: struct breakpoint's shadow_contents now sized as
        BREAKPOINT_MAX.
        (insert_breakpoints):  Vector to target to install breakpoints.
        (remove_breakpoints):  Vector to target here too.
        Remove REMOTE_SA_SPARC kludges and other remote_debugging.
        sparc-tdep.c (single_step):  Use new breakpoint interface for
        the single-step breakpoints.
        mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
        New file, contains routines to insert and remove breakpoints by
        reading out the old contents and later replacing them.  This is
        how ptrace breakpoints work, and many remote systems as well.

        * tm-vxworks68.h:  New config file, overrides a few things for
        Wind River's preferences.

        * target.h:  New file, for transfer vector used to talk to the
        inferior (child, attached, core, exec, remote, etc).  All accesses
        to the thing being debugged should come through these vectors.
        target.c:  New file, routines to handle transfer vector.
        (various files):  Add transfer vectors XXX_ops for the various
        targets and pseudo-targets (core files, etc) we support.

        * breakpoint.c (bpstat_stop_status):  Further explorations of
        watchpoints and why things don't work all the time.
        (bpstat_alloc):  New fn to allocate a bpstat and chain it.

        * config.gdb:  Only add "source ${srcdir}/.gdbinit" to
        the local gdbinit if it doesn't already have it.

        * core.c (core_ops):  add and install.
        Allow core debugging without exec file.

        * dbxread.c (free_and_init_header_files):  Merge two fns.
        (end_symtab):  Free named symbol table when a new version comes in.
        (read_dbx_symtab):  Relocate all kinds of symbols with base
        address.  First step toward handling different text, data, bss
        reloc.
        (add_file_addr_command):  Renamed add_file_command.
        (add_file_command):  Vector to remote handler.
        Add "load" as an alias for "add-file" command.

        * defs.h:  Allow "volatile" to be used in non-ANSI; use it for
        non-returning functions.

        * exec.c:  Add exec_ops, and push it as a target when an exec
        file is specified.

        * infcmd.c (run_command):  Pass executable file name and arg list
        separately when starting an inferior.  Permit "run" when no exec
        file is specified, for VxWorks.
        (detach_command):  Move to child_detach in inftarg.c.

        * inftarg.c:  New file.  Unix-child-specific routines, and the
        child_ops structure.

        * inferior.h (registers):  Export "registers" as the way for
        target dependent register handlers to find gdb's local copy of
        the registers.  Rename "stop_after_attach" to "stop_soon_quietly"
        since it is now used by places that want wait_for_inferior to
        handle the grunge but want to see every trap from the inferior.

        * inflow.c (create_inferior):  Pull out, and merge into infrun.c.
        Eliminate remote_debugging hooks in terminal handling.

        * infrun.c:  Replace start_inferior with child_create_inferior.
        Move all the hair of Unix shells and ptrace idiosyncracies into
        child_create_inferior, so remote handlers don't have to deal.
        Remove running_in_shell.  Rename stop_after_attach to
        stop_soon_quietly, and use it in a few other places where we want
        to just call wait_for_inferior and get control back on the first
        trap.  trap_expected now never takes a value > 1.
        (init_wait_for_inferior):  Initialize static vars when a new
        process is created.

        main.c (gdbinit):  Add new hook for .gdbinit file name, let
        it be overridden by config files as GDBINIT_FILENAME.
        (DEFAULT_PROMPT):  Add new hook for overriding (gdb) prompt.
        Both of these are used for VxWorks gdb.

        mcheck.c:  rename include file "gmalloc.c" to avoid problems
        with system include file "malloc.c".

        param-no-tm.h:  New include file, same as param.h but does not
        include the default "tm.h" file.  This is used in files where
        the target is known, e.g. remote-eb.c or sparc-xdep.c.

        param.h:  Now just a shell that includes tm.h and param-no-tm.h.

        remote-vx.c:  New file, VxWorks remote debugging support.  Uses
        RPC routines that are shared with the target system, in directory
        ${srcdir}/vx-share.

        remote.c:  Vectorize remote interface.

        source.c:  Globalize source_path, and make an alias "l" for "list"
        since we now have the "load" command.

        sparc-xdep.c:  Use new param-no-tm.h.

        symmisc.c (free_named_symtab):  Add new function from Wind River.
        However, ifdef it out for now while we think about what it should
        really be doing.

        tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
        PREPARE_TO_STORE to
        the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
        non-Unix-children handle this with their own code in the target
        transfer vector.

        Makefile.dist:  Roll version to 3.92.3.  Add vx-share stuff to
        source and target lists.  Add vx-share to default list of include
        directories.  Add new files to src and target lists: mem-break,
        target, inftarg, remote-eb, remote-vx, targ-vx.  Be sure the
        ${srcdir} versions of munch and createtags are used.

        * valops.c (find_function_addr):  Split out of call_function.
        (call_function_by_hand):  Rename call_function; this function 
        calls functions in the target by laboriously patching the target
        word-by-word with the right stack, args, regs, etc.


Mon Nov  5 17:29:10 1990  John Gilmore  (gnu at cygint)

        Handle AMD 29000 a bit better.

        * remote-eb.c (readchar):  Mask received char log to make it readable.
        (remote_start):  Pass arguments down to executing program.
        Make startaddr unsigned.
        infrun.c (start_inferior):  Accept args, pass them to
        remote_start.
        infcmd.c (run_command):  Pass args down to start_inferior.

        * tconfig/am29k-aout, tconfig/am29k-coff:  New files specifying
        the target object file format.
        tm-29k.h:  Pay heed to COFF_ENCAPSULATE.

        * am29k-pinsn.c (print_insn):  Print 0x on hex numbers in disassembly.
        am29k-tdep.c (examine_prologue):  Better checking of function prefixes.

Sun Oct  7 18:20:45 1990  John Gilmore  (gnu at cygint)

        * Makefile.dist (VERSION):  Roll version to 3.91.9 and freeze.
        * TODO:  We did a few things, we have more to do though.

        * xm-sparc.h (CLEAR_DEFERRED_STORES):  Define.
        * inflow.c (inferior_died):  Clear deferred stores.
        
        * Debug problems with dummy frames and calls to the inferior.
        * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME):  Move to sparc-tdep.c.
        * sparc-tdep.c (do_restore_insn):  Simplify.
        (sparc_frame_find_saved_regs):  Simplify and fix what we find.
        (sparc_push_dummy_frame):  Simplify and fix what we push.
        (sparc_pop_frame):  Slightly more hair here, deciding whether
        we are restoring a saved PC or returning to a return address in %i7.
        * sparc-xdep.c (read_inferior_registers):  Debug if valid reg is read.

        * utils.c (xmalloc, xrealloc):  Return type depends on __STDC__.
        * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
        * obstack.h (chunkfun): ditto.
        * defs.h (xmalloc, xrealloc): ditto

        * utils.c (quit):  Grab the terminal from the child if necessary. 

        * inflow.c (term_status_command): Rename to term_info, change
        to "info terminal".

        * sparc-pinsn.c (print_insn):  Disassembly prefers real instructions.
        (is_delayed_branch):  Speed up.
        * sparc-opcode.h: Add ALIAS bit to aliases.  Fix up opcode tables.
        Still missing some float ops, and needs testing.

        * Support for input and output radixes other than base 10
        * defs.h (input_radix, output_radix):  Declare.
        * expread.y (yyparse, parse_number):  Handle changes of input
        radix, and ambiguous names-or-numbers in radixes >10.
        * printcmd.c (print_scalar_formatted):  Print formatted hex
        numbers in varying column widths.
        * valprint.c (val_print):  Use output_format to print scalar ints.
        (set_input_radix, set_output_radix, set_radix):  Create.
        (set_output_radix):  Set output_format from output_radix.
        (_initialize_valprint):  add `set radix' but leave the others off.
        
        * main.c (execute_command): Let stupid questions be turned off.
        (_initialize_main): Handle "set stupidity", etc.

        * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h, 
        sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c:  Lint.

Tue Oct  2 11:20:02 1990  John Gilmore  (gnu at cygint)

        * TODO, Makefile.dist, ChangeLog:  Freeze for 3.91.8 release.
        bfd stuff is still screwed up, but with some manual work, it
        compiles.

        * breakpoint.c (bpstat_do_actions):  Start over if a command
        proceeds the inferior, since the inferior will have stopped and
        will need to have its new stop-actions taken care of.

        * dbxread.c (read_struct_type):  Expression gives Sun3 4.0.3
        compiler fits, simplify it.

        * gdb.texinfo (directory command): Doc new dir command.
        source.c (directory_command):  "dir" now puts things on the front
        of the path, moves dups up front, and handles multiple names
        on the command line, inserting each one in order.  It also
        blows away cached line and full_filename info.

        * stack.c (backtrace_command):  Skip "more stack frames follow"
        unless interactive.

        * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
        xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h, 
        xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
        The only odd one was Gould NP1, which had defined vprintf to
        "printf"!!!

        * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
        printcmd.c (print_command_1): Pass 'inspect' flag down as a global
        variable, inspect_it.
        valprint.c (print_string, val_print): Use the global inspect_it
        to indicate whether to print in Epoch style or normal style.    

Mon Oct  1 23:55:26 1990  John Gilmore  (gnu at cygint)

        * printcmd.c (call_command):  add an alias for the "print" command
        which runs expressions and doesn't print the result if void.
        (print_command_1): implement it.

        * command.c: Remove #if 0'd code.  Initialize all the fields
        in add_cmd ().  Rename do_nothing_command to
        not_just_help_class_command, and make it externally visible.
        command.h: add user_commands to struct.
        * main.c (define_command):  Don't overload c->function with a char
        string as well as a function pointer.

        * eval.c (evaluate_subexp):  Reinstall tiemann changes to
        calling convention of value_struct_elt () that got dropped in
        merge.

        * tm-sparc.h (FRAME_FIND_SAVED_REGS):  move to sparc-xdep.c.
        sparc-tdep.c (sparc_frame_find_saved_regs):  ditto.

        * tm-sparc.h (POP_FRAME): replace some constants with defines.

        * sparc-xdep.c (store_inferior_registers):  defer stores to regs
        until a good time (e.g. when we are about to run the child),
        saving ptrace calls.
        * infrun.c (proceed):  handle DO_DEFERRED_STORES.
        * tm-sparc.h: define DO_DEFERRED_STORES.

        * sparc-xdep.c (store_inferior_registers): when storing float
        registers, don't store stack regs too.  When storing the SP,
        however, DO store the stack regs too.  This fixes a bug in which
        the dummy frame is not recognized when a call_function finishes,
        because its frame pointer (in the stack regs) was never
        initialized.
        (read_inferior_registers):  Mark WIM and TBR and FPS and CPS valid
        even though we don't know how to read them from an inferior.
        valops.c (call_function):  Comment about storing SP.

        * infrun.c (save_inferior_status): Save away the original bpstat
        chain so it can be restored later.  Install the copied version for
        use by whoever saved the status.  It will be blow away by
        restore_inferior_status, and the original chain restored.  This is
        important for people who have pointers into the original.

        * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
        findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
        main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint


Fri Sep 28 20:32:46 1990  John Gilmore  (gnu at cygnus.com)

        * Makefile.dist: Roll version to 3.91.8.  Add bfd.h and bfdconfig.h
        temporarily to the makefile.  Add am29k-opcode.h and WHATS.NEW.
        Add stuff.c and kdb-start.c to the OTHERS list for tar files.

Fri Sep 28 19:12:12 1990  John Gilmore  (gnu at cygint)

        * Merge Mike Tiemann's multiple inheritance changes from Sun.
        Store the baseclasses in a type struct starting from array element
        0 rather than from the unusual array element 1.

        dbxread.c: the above.
        (virtual_context): Add
        Read new debug information about which virtual function table
        a virtual function is from, and store it in fn_field.fcontext.
        
        symtab.h: Add fcontextt.  Fix baseclass indices.  Typo in
        TYPE_FN_FIELD_STATIC_P.

        symtab.c: the above.
        valops.c: the above.  Handle pointer casts of object *'s.
        (search_struct_method): Add.
        (value_struct_elt): First arg is now a pointer to a value, and is
        modified on return.

        valprint.c: the above.
        values.c (value_virtual_fn_field): Add type arg.  Handle
        offsetting to the proper object when calling virtual fns.
        The above.
        (baseclass_addr): Add valuep arg.

        * README:  Document the current state of BFD config (missing).
        * TODO, ChangeLog, Makefile.dist: Roll version.
        * WHATS.NEW: Add summary of changes since 3.5.

Thu Sep 27 16:23:12 1990  John Gilmore  (gnu at cygint)

        * dbxread.c (read_struct_type): Clear bit vectors whenever
        we allocate one.
        symtab.c (B_CLRALL): define.

        * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
        using == rather than =.  Huh...  This fixes the dreaded problem
        wherein builtin_type_int becomes TYPE_CODE_FLT.

        * core.c (info_files): Show the inferior pid.

        * config.gdb: Avoid putting "dir" command into .gdbinit.  GDB
        already knows how to look in the source directory.

        * Remove psymtab hair from many places.  Remove duplicated code
        for searching symbol tables.  Hide psymtabs from most places.
        Make it fast to get from a psymtab to its symtab.

        blockframe.c (blockvector_for_pc): Remove psymtab hair.
        coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
        mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
        dbxread.c: export psymtab_to_symtab, make it work if called N times.
        (psymtab_to_symtab): Rename to psymtab_to_symtab2.  Initialize
        new symtab completely.  New psymtabs get symtab pointer
        initialized to zero.  Remove MI warning printf.  
        symtab.h: Comments.  Add psymtab to symtab pointer.
        (PSYMTAB_TO_SYMTAB): New macro.
        symtab.c: use PSYMTAB_TO_SYMTAB.  Add psymtab_to_symtab and export it.
        source.c: use PSYMTAB_TO_SYMTAB.  Remove symtab version and
        compilation fields.
        stack.c (backtrace_command): Avoid pre-pass to read symbols, if
        verbose is not set.
        (print_frame_info): Avoid special-casing symbols that have not yet
        been read in.

        * source.c (open_source_file): Quick path if we have already
        located the source file by its full name.

        * symtab.c (lookup_symbol): Use find_pc_symtab rather than
        find_pc_psymtab.  When a name is found in the misc function
        vector, search the symbol table for its mangled name, not the
        name that the user typed.

        * bfd.h: Fix missing comment terminators, make #endifs match.

        * valarith.c (value_less): Handle unsigned int comparisons.
        Add FIXME about pointer compares, which assume host and target
        pointers are the same.

        * command.c (do_nothing_command): lint
        dbxread.c: lint.  Remove sort_syms.  Document C++ visibility info,
        fix comments on debug symbol format for visibility.  Actually set
        visibility of symbols.
        main.c (echo_command): lint; use <readline/history.h>.
        tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
        obstack.h (_obstack_blank): Rearrange pointer math to avoid
        pointing past end of allocated memory; saber complains.
        obstack.h: Declare the external functions that we use.
        valarith.h: use <string.h>
        solib.c (solib_add): lint.

Fri Sep 21 17:05:19 1990  John Gilmore  (gnu at cygint)

        * main.c (initialize_main):  Default info_verbose to off, now that
        symbol reading is fast.
        (quit_command):  Avoid clobbering exec_bfd while quitting.

        * Initial BFD (binary file diddling library) merger:
        coffread.c: Change AOUTHDR to struct exe_hdr.
        dbxread.c: ditto.
        core.c: initialize initialized data at compile time.
        (core_file_command):  Move from coredep.c, convert to bfd.
        (xfer_core_file): Convert to bfd.
        exec.c (exec_file_command): use bfd routines.
        gdbcore.h: BFD.
        mips-tdep.c: Remove exec_file_command and friends.
        source.c: bfd.
        
        * coredep.c: (fetch_core_registers) Convert core_file_command to
        fetch_core_registers.
        mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
        
        * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
        (my_bfd_read): More bogosity, which I don't think we call.
        (program_name): Remove this atrocity asap!

Wed Sep 19 13:36:41 1990  John Gilmore  (gnu at cygint)

        * From Per Bothner:
        values.c: allocate_repeat_value was not clearing the
        optimized_out field.
        (value_static_field): minor stylistic fix (wrong macro was used).
        valops.c (value_struct_elt_for_address): didn't work for C++
        static fields.

        * signame.c (_initialize_signame):  Initialize signal names once.

        * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
        exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
        symtab.h, tm-29k.h, valprint.c, value.h, values.c:  Lint.

        * remote-eb.c:  Support user-settable baud rates on the serial port.

        * tm-sun3.h (PREPARE_TO_STORE): fix typo.

Fri Sep 14 13:28:29 1990  John Gilmore  (gnu at cygint)

        * tconfig/sun3os4: Remove warning about native assembler,
        since it also occurs in the xconfig file.

        * findvar.c (registers): Allocate some slop after `registers'
        to prevent stray accesses from trashing the next variable.

        * tm-68k.h (REGISTER_BYTES):  Allocate the right number of bytes
        on the sun-3, by changing the #ifdef from `sun3' (which is not
        defined by cc) to `sun'.  Symptom was trashed builtin_type_XXX
        vars, which happened to follow `registers' in the executable.

        * readline/history.c (history_search): Heed gcc-2's advice
        and parenthesize && inside ||).

        * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
        tm-29k.c:  Insert FSF copyright headers.

        * remote-eb.c:  Better comments.

        * Makefile.dist:  Update to 3.91.6.
        * TODO: note PREPARE_TO_STORE problem.

Thu Sep 13 09:52:33 1990  Jim Kingdon  (kingdon at cygint)

        * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.

        * remote.c:  Wrap the whole file in #if !defined (SPECIAL_REMOTE).

        * infrun.c (wait_for_inferior, at end): Don't set up
        prev_* if the inferior no longer exists.

        * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
        CANNOT_EXECUTE_STACK.
        valops.c (call_function): Use it.

        * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.

        * inferior.h (PC_IN_CALL_DUMMY): New macro.
        infrun.c (wait_for_inferior, 2 places): Use it.

        * values.c (value_being_returned): Only use
        EXTRACT_STRUCT_VALUE_ADDRESS if defined.

        * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
        right thing for remote-eb.c.  

        * sun3-xdep.c:  Remove extraneous call to remote_store_registers.
        * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c:  Ditto.

        * blockframe.c:  Put get_frame_saved_regs inside #if !defined
        (FRAME_FIND_SAVED_REGS).

        * findvar.c ({fetch,store}_registers): Check for
        REMOTE_{FETCH_STORE}_REGISTER macro.

        * findvar.c (get_saved_register): Add argument lval and
        change meaning of argument addr.
        findvar.c:  Change calls to get_saved_register to reflect
        new calling convention.
        valops.c (value_assign): Use get_saved_register instead of
        find_saved_register.

Sun Sep  2 12:40:20 1990  Jim Kingdon  (kingdon at cygint.cygnus.com)

        * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
        an (uninitialized) pointer to one.  Use "&" when passing it
        to fread.

Fri Aug 31 22:57:54 1990  Jim Kingdon  (kingdon at cygint.cygnus.com)

        * coffread.c (getfilename): Use DGUX x_offset and x_name if
        defined.

        * coffread.c (symbol_file_command): Put semicolon after
        "int from_tty".
        Put safe_to_init_tdesc_context in #if defined (TDESC).
        Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
        coffread.c: #include <sys/stat.h>.
        (read_coff_symtab): Typo: in_source_files -> in_source_file.
        Add missing ')' in check for "lc%" and friends.  Remove
        extraneous '}'.
        Declare read_one_sym() at top of file.
        (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
        MC68WRMAGIC can have the same value without causing a duplicate
        case.

Thu Sep 13 15:55:36 1990  John Gilmore  (gnu at cygint)

        * Allow a Makefile to be built without building the
        tm and xm file links that screw up builds in subdirectories.
        This is done with `config.gdb none', then you can do things
        like `make gdb.tar.Z'.
        * tconfig/none: Config file for no target system
        * xconfig/none: Config file for no host system
        * config.gdb: If no TM or XM files are called out by the
        host or target file, don't make links for them.

        * cplus-dem.c: Add documentation.

        * dbxread.c (read_ofile_symtab): Turn a fatal error into a
        simple error, so the user's gdb doesn't crash due to some object
        file problem (e.g. somebody is rebuilding the file out from under
        gdb).

        * printcmd.c (print_address_symbolic): demangle the symbol.

        * Makefile.dist (OTHERS): Remove tdesc-lib because it has 
        Motorola copyrights in it.  Make "make gdb.tar.Z" work.
        (alldeps.mak): sort and uniq all results from this; duplicates
        hose gdb.tar.Z link building.  Remove RCS files from
        tconfig and xconfig.  Add config files for sun386.  Add
        a few odd files to OTHERS and HFILES.

Mon Sep 10 21:20:24 1990  John Gilmore  (gnu at cygint)

        * Makefile.dist: Pull solib.c to tconfig/sun?os4.
        Roll version number to 3.91.5.  Make lint work in bindir.

        * README:  Document cross-debugging and new file structure.

        * blockframe.c: Lint.  Include "value.h" to declare read_register.
        (find_pc_partial_function): remove duplicate line.

        * command.h: Lint.  Declare error_no_arg and dont_repeat.

        * tm-news.h: Remove inadvertently duplicated stuff.

        * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
        Clean up usage of misc_function_type.  Declare some CORE_ADDRs.

        * config.gdb: Allow `config.gdb host target' form.  Clean
        up previous change that printed bogus messages when you just said
        `config.gdb'.

        * core.c: #include "command.h" for lint.
        * dbxread.c: lint
        * eval.c: lint
        * main.c: Remove some casts of enums.  Lint.
        * source.c: lint
        * symtab.c: lint
        * symtab.h: lint
        * expread.y: lint
        * valarith.c: lint

        * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
        
        * sparc-tdep.c (isannulled): Take instruction as parameter, don't
        read it from memory.  This will allow us to save ptrace calls
        eventually.   Changed caller single_step too.

        * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
        that we aren't going to use, saving many ptrace calls, especially
        when watchpointing or single stepping.  Use some #define's for
        constants.
        (store_inferior_registers): Ditto.
        (core_file_command): Use some #define's for constants.

        * tm-sparc.h: Add #define's for some register numbers, so we
        can eliminate the use of random constants in sparc-xdep.c.

        * stack.c (frame_command, print_frame_info, up_command,
        down_command) Remove frame_changed, since it
        causes a bug and doesn't seem to do anything useful.  In some
        places it was used as a flag, in others as a stack level (?).

        * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
        default is to use the portable (vprintf) version rather than the
        kludge version.
        * xm-news.h (MISSING_VPRINTF): Add.

        * valprint.c (val_print): Demangle fancy vtbl printouts.  Lint.

Sat Sep  8 00:24:12 1990  John Gilmore  (gnu at cygint)

        * Remove stuff that forces -Bstatic linking of gdb, and warnings
        about linking debugged programs -Bstatic in the sun?os4 config
        files in tconfig and xconfig subdirectories.

        * main.c (main):  Remove unreached exit(0) now that we exit
        via quit_command().

        * Create TODO file for online bug list.  There are too many
        "little" bugs to keep track of on paper.

        * Change Projects file to refer to bug-gdb@cygnus.com
        rather than kingdon@ai.

Fri Sep  7 23:35:15 1990  John Gilmore  (gnu at cygint)

        * Makefile.dist (VERSION): 3.91.4 now.

        * symtab.c (init_misc_bunches): Rename from init_misc_functions.
        (condense_misc_bunches): Add sanity check that misc_count is
        the same as the number of symbols in the bunch.
        
        * coffread.c: rename init_misc_bunches.  Pass an argument 
        to condense_misc_bunches (a zero).

        * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
        every time we are called; don't rely on our caller to do it.
        (add_file): Remove call to init_misc_bunches.

        * mipsread.c: Only warn, don't error, if unknown symbol types.
        This keeps an old gdb from falling on its face if it sees newly
        extended symbol info.  Rename init_misc_bunches.

Fri Sep  7 22:58:15 1990  John Gilmore  (gnu at cygint)

        * Merge in changes from Per Bothner for DECstations and other
        MIPS stuff.  The rest is Bothner speaking:

        The next message is a merger of Alessando Forin's mips port with
        mine.  I've tried to use my good if biased judgment to get
        the best of both. It *does* need testing.

        Some of the changes are general, *not* mips-specific.

        param.h:
        Didn't believe in little-endian bit order.
        There are still inconsistencies about whether flags
        like BITS_BIG_ENDIAN are integer (#if ...) or
        boolean (#ifdef ...). I tried to paper over them.

        dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
        Moved some misc_function code that was common to
        {dbx,coff,mips}read.c to symtab.c.
        In the process, I think I cleaned things up a bit.
        At the same time, moved obsavestring and obconcat to symtab.c.

        dbxread.c:
        Removed obsolete condense_addl_misc_bunches (use
        condense_misc_bunches(1) instead).

        exec.c:
        Needed to include <sys/dir>, at least on DECstations.

        valops.c, mips-tdep.c, tm-mips.h:
        Added PUSH_ARGUMENTS macro to support funny argument-pushing
        conventions (when STACK_ALIGN is insufficient).
        Needed on mips, where doubles need 8-byte alignment,
        but ints only need 4.

        mips-opcode.h:
        Removed cruft that was not being used.
        Merged in many fixes (most from Frank Yellin, fy@lucid.com).

        mips-pinsn.c:
        Print $ before register-names (I think that makes things a little
        more consistent).
        Never print two instructions, even if one delays.
        Removed hex-disassemble set_cmd.  (This is not mips-specific,
        so I think the argument is whether it is generally worthwhile or not.
        I'm inclined to think not, given how easy it is to
        convert between radixes in gdb.)

        mipsread.c:
        This is basically Alessando's code.
        It doesn't use obstacks; I changed it to use obstacks
        in a few minor places where using malloc causes a
        memory leak. (Probably, more places could/should be changed.)
        I added record_misc_function where it was missing.
        In symbol_file_command and add_file_command, I tried
        to make the code consistent with more recent versions.
        Minor sylistic changes in parse_procedure.
        Make a .gdbinfo. psuedo-symbol point back to the real
        procedure symbol (using the isym field).

        mips-tdep.c:
        This is basically from my port, but with a lot of details
        and a number of routines merged in from Alessando's version.
        I basically used my code "raw" backtrace (use heuristics
        from the actual code, rather than symbol table info) - though
        the idea is Alessandro's. I feel my code is a little cleaner
        here, particularly in being a little more flexible, such as being
        able to handle gcc-produced code (which it now can).
        It also doesn't do frame caching (which is not useful
        more recent gdb versions).
        I also used my code for push_/pop_dummy, more or less.
        I tried to incorporate AF's code for testing sigtramp
        while backtracing; I probably got it wrong.
        Added mips_print_register, which tries to scrunch as much
        information as possible on a screen...
        Removed the skip-prologue set_cmd. As with hex-disassemble (see
        under mips-pinsn.c), I don't see anything mips-specific here,
        and I don't see it being all that useful anyway.
        
        tm-mips.h:
        Added a $fp psuedo-reg distinct from $fp (nice for gcc).
        Use more register names (rather than hard-cases numbers).
        
Thu Sep  6 18:33:15 1990  John Gilmore  (gnu at cygint)

        * Hack up 3.90.11 changes:

        * Makefile.dist (depend): parameterize $(GCC).
        Add solib.c and solib.o.
        (readline): Fix vpath for both absolute or relative SRCDIR.

        * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
        Also, let the part I didn't understand at least compile so
        I can test the rest.  FIXME.

        * dbxread.c: Fix thinko using strcmp.
        (init_psymbol_list): declare static.
        (partial_symbol_file_open): Comment cleanups better, avoid
        cleaning up the string table since the caller will do that.
        Move the stat for mod time into symbol_file_command, temporarily.
        (There should be a mod time for each symbol file, eventually,
        to control its rereading.  FIXME.)

        * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
        SunOS, which gives error for shared libs otherwise.  (From
        Schaefer, probably FIXME needs work for portability.)

        * solib.c:  Move #include "param.h" to work.
        Lowercase all the Uppercase Letters In the Messages.
        (find_solib): Clean up inferior_so_name for debug printouts.
        Allow no argument, to mean all shared libraries.

        * symmisc.c: include param.h to get CLEAR_SOLIB.

        is found, set *address = pc - FUNCTION_START_OFFSET.
        breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
        Disable breakpoints instead of giving an error.
        source.c (select_source_symtab): Initialize cs_pst.

        Take code which is shared between symbol_file_command and
        add_file_command and put it into partial_symbol_file_{open,read}.
        Split add_file_command into add_file_command and add_file.
        Make psymtab_to_symtab read in the string table if the file

        Two new parameters to read_dbx_symtab and start_psymtab.
        tm-sunos.h: New file.

Tue May 22 17:43:03 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)

        * infcmd.c: Change cont_command to continue_command and "cont"

        * breakpoint.c (enable_breakpoint): Get value of watchpoint.

        * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.

        * values.c (USE_STRUCT_CONVENTION): Check for structures of
        size 1,2,4,8 rather than size < 8.

        * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
        as necessary, not just once.

        * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.

Thu May 17 15:04:09 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)

        * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386

Sat May  5 12:39:18 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)

        * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
        VPATH to readline.
        config.gdb: If srcdir != ., create readline directory and
        copy a makefile into it.

        * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
        consistency with POSIX.

        * breakpoint.c (bpstat_stop_status): Disable watchpoint
        when we exit its exp_valid_block.

Tue Sep  4 11:46:46 1990  John Gilmore  (gnu at cygint)

        * Makefile.dist: Bump version to 3.91.3.

        * Clean up handling of breakpoint commands (somewhat).
          Prompted by Tiemann bug report "cont 10" doesn't work any more.

          inferior.h: Add breakpoint_proceeded to inferior status struct
          and globals; save it and restore it.
          (clear_breakpoint_commands): Cleanup, remove old #define.

          infrun.c (clear_proceed_status): Set breakpoint_proceeded.
          (save_inferior_status, restore_inferior_status): handle it also.
          (proceed): Remove earlier code that set breakpoint_proceeded.
          It is now set only in clear_proceed_status.
          (clear_proceed_status): Cleanup, use bpstat_clear rather
          than clear_breakpoint_commands.  No callers need the stop_bpstat
          between clear_proceed_status and proceed.

          infcmd.c: Add breakpoint_proceeded definition and comment.
          (cont_command, jump_command, signal_command): Move call to
          clear_proceed_status right next to call to proceed.

          breakpoint.c (bpstat_do_actions): Avoid clobbering our
          caller's argument while running down the chain of breakpoints.
          Use new variable "breakpoint_proceeded" to determine when
          a command that it executes moves the inferior past the
          breakpoint.
          (bpstat_clear): Handle NULL argument.
          (bpstat_clear_actions): Avoid useless call to
          breakpoint_auto_delete.
          (delete_breakpoint):  Clean up bpstat's that are pointing to
          the deleted breakpoint from the stop_bpstat chain.
          (breakpoint_auto_delete): Simplify.

        * Clean up handling of EOF, error on stdin, etc.  This was
          prompted by a network problem that caused gdb to go into an
          infinite loop filling up its malloc'd memory.

          main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
          not clear_breakpoints_commands, which is now gone.
          (main): If command_loop returns (e.g. from EOF on stdin), do
          a quit_command (looping back to command_loop if quit_command
          doesn't really quit).
          (command_loop): check result from command_line_input and
          exit if it returns NULL, rather than passing the NULL to
          execute_command.
          (gdb_readline):  Free malloc'd result space before returning
          NULL for EOF.

        * utils.c (query): Handle C-d to mean "yes", just as if the
          input was not a terminal.  Also avoid infinite loop if EOF
          occurs in mid-input-line before newline.  This allows
          query to be used at EOF on stdin with reasonable results.

        * infrun.c (proceed): Set breakpoint_proceeded.

        * values.c (value_as_long): Avoid infinite recursion for enums.
          (_initialize_values): Fix typo in help msg (kingdon).

        * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
          RL_LIB for linking.  This allows -lreadline for linking
          and nothing for dependencies, once readline is a real library.

        * config.gdb: Jim Kingdon: give useful error message if the
          host or target type is not recognized.

        * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
          it just defines it.  Dumb, but deal with it.

        * Jim Kingdon suggests:
          in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.

Wed Aug 29 18:03:27 1990  John Gilmore  (gnu at cygint)

        * Makefile.dist (VERSION): Bump version # to 3.91.2.

        * Clean up Bothner's changes.

        * blockframe.c (clear_pc_function_cache): New function.
        * blockframe.c: remake cache_pc_function_* static.
        * dbxread.c (symbol_file_command): remove references to
                    cache_pc_function_* variables.
        * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
        * printcmd.c: Avoid kludging a global variable (addressprint)
          to avoid printing the address of a string twice.  Instead,
          pass the format letter 's' down low enough that it can be seen
          to avoid this problem.
          (print_formatted): Pass format arg to value_print.
          (restore_addressprint): Remove function.
          (do_examine):  Avoid hacking addressprint, cleanups and such.
          (print_frame_args):  Add a comment to a Bothner change.
        * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
        * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
          to wipe out the values cached in blockframe.c.
        * symtab.c (find_method): Add comment saying how big you must
          allocate to be "big enough".  Per being terse again.
        * valprint.c (val_print): Handle format letter "s" to print
          strings without addresses.  Add comment to vtbl printing code
          which casts with wild abandon.  Rearrange reference-printing
          code so it prints:
               @0xaddr: value           (print w/addressprint)
               value                    (print w/~addressprint)
               @0xaddr                  (parameter lists w/addressprint)
          or   nothing                  (parameter lists w/o addressprint)

Tue Aug 28 10:47:18 1990  John Gilmore  (gnu at cygint)

        * Merge more changes from Per Bothner:

Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
annoying) that I tried to improve it. Here are my suggestions.

        These patches all attempt to handle TYPE_CODE_REF (as in C++) better.

        findvar.c:
        Do automatic de-reference when taking the address of a reference.
        printcmd.c:
        Don't deref_ref when printing parameter lists.
        valops.c:
        More attempts at treating refernences properly.
        valprint.c:
        In val_print, if deref_ref==0, don't print dangling " = ".
        value.h:
        Add COERCE_REF macro, which de-references an REF.

        * Merge changes from Per Bothner:

* Fixed (Sony news)-specific configuration problems.
* Fixed other problems with using vanilla pcc and libc (enum problems;
assumption that vsprintf exists).
* Some major speed-ups (finc_pc_partial_function now caches a match;
parsing avoids duplicate symbol_lookup calls).
* Changed handling of baseclasses (no longer use baseclasses field
of struct type, use the first n_baseclasses fields instead).
* Various minor changes/fixes, most C++-related.

blockframe.c:
Cache the most previous match from find_pc_partial_function.
(Save both low and high ends of matching function's pc range.)
This speeds up the loop of infrun.c:wait_for_inferior quite
a bit, and makes step/next commands much zippier.
command.c:
Added an enum->int cast (otherwise, some compilers barf).
dbxread.c:
No longer set baseclass offset to 0, since multiple
inheritance now mostly works.
Added a number of casts, to shut up compiler warnings
(after stabs where made enums, not ints).
When discarding a symbol table (in symbol_file_command),
must clear the cache introduced in blockframe.c.
Don't convert $vtbl_ptr_type to vtbl any more.
Get rid of TYPE_BASECLASEES and  baseclass_vec (see also symtab.h).
Mask off sign bit emitted by g++ for virtual table offset.
Set voffset to -1 (not 1) for static member functions.
expread.y:
Changed parsing/lexing of names to avoid doing symbol lookup twice
(once when lexing to determine symbol class, once for real).
Now only call symbol_lookup once. Fields of 'this' win especially big.
printcmd.c:
Subpress printing addr twice in the case of 'x/s addr'.
symtab.c:
lookup_basetype_type is no longer used.
Add find_methods as recursive helper function to decode_line_1.
This allows multiple inheritance to work.
Also, once one or more matches has been found, do not look in
base-classes. (Baseclass methods would be overridden, anyway.)
symtab.h:
Removed baseclasses array in struct type.
Instead of using baseclasses[i], use fields[i-1].
Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
Changed sign convention of voffset (previous was inconsistent).
tm-news.h:
Some macros (CALL_DUMMY and relatives) were missing. Put them back.
utils.c:
Used to assume existence of vsprintf. Re-written to not need it
if HAVE_VPRINTF is undefined.
valops.c:
typecmp was too pessimistic. Made it less so.
valprint.c:
Don't print space after address.
If vtable points to a misc symbol (with 0 offset), print it,
since that indicates the actual class of the object.
Changed ype_print_derivation_info to use new inheritance
scheme (without baseclasses vector).
values.c:
In value_primitive_field, fixed some bugs left over from previous set of fixes.
Also, changes needed because TYPE_BASECLASSES were removed.
xm-news.h:
REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.

Tue Aug 21 20:08:54 1990  John Gilmore  (gnu at cygint)

        * source.c:
  If there is no path set, and the symbols don't indicate what directory
  a file was compiled in, look in the current directory.  But either
  a path or a known compilation directory will prevent this.

        * dbxread.c:
  Three independent bug fixes:
   * Remove the #if 0 block that breaks some stuff.
   * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
     adapt gdb to either SunOS 4.0.* or 4.1.
   * MAX_OF_TYPE and MIN_OF_TYPE thinko.  By tedg@sun, I think.
 
        * symtab.c:
  Instantiate the class T when looking for methods in it.  (Tiemann@sun)

        * valprint.c:
  (type_print) Demangle the name being printed.
  (type_print_base) Handle botched demangling without coredump (tiemann).

        * values.c:
  (check_stub_method):  Document routine.
                        (tiemann) fix bug for no-arg functions
                        Avoid clobbering beyond end of malloc'd storage.
                        Terminate the argument list properly.

Sat Aug 18 01:29:59 1990  Per Bothner (bothner@cs.wisc.edu)

        * Changes merged by John Gilmore:
    
breakpoint.c:
  In breakpoint_1, use new print_address_symbolic instead
  of find_pc_partial_function. (This forces use of assembler-level
  addresses, and avoids misleading non-mangled source-level names.)
cplus-dem.c:
  Generalize ansi argument such that -1 means skip arglist totally.
  Removed global variable print_ansi_qualifiers (which made
  code non-reentrant), in favor of extra explicit arguments
  to internal routines.
printcmd.c:
  Add new helper function print_address_symbolic.
  Use find_pc_misc_function instead of find_pc_partial_function
  (since we want assembler-level symbols here).
stack.c:
  Print unknown function as just "f (...)", not "f (...) (...)".
  Use new fputs_demangled explicitly.
symtab.c:
  Fixed a typing violation (problem: value.h cannot be imported
  without renaming many variable in this file).
  lookup_symbol: If no matching misc_func, look for a C++-mangled name.
  decode_line_1: Moved forward some never-reached code.
  Made decode_line_2 skip function prologues correctly.
utils.c:
  fputs_filtered should not demangle by default.
  Add new fputs_demangled to demangle on demand..
valops.c:
  Change value_struct_elt to use value_primitive_field (using recursive
  utility function search_struct_field). This allows foo.bar to work
  for multiple inheritance (so far only for data fields).
  Change check_field in the same way (recursive helper function
  to support multiple inheritance).
  (Note: there are more of these problems that I haven't fixed.
  Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
  value_of_this: 'this' symbol name is now just "this", note "$this".
valprint.c:
  Don't print static members.
  Avoid printing "members of <type>" if there are none.
  Simplified type_print_derivation_info by merging duplicate code.
  Remove useless blank lines in type_print_base (ptype command).
value.h:
  Added declaration of new routine value_primitive_field.
values.c:
  Added value_primitive_field which is generalized version of
  value_field that can handle multiple inheritance (non-zero offsets etc).
  Re-implemented value_field to call value_primitive_field.

Fri Aug 17 23:33:44 1990  John Gilmore  (gnu at cygint)

        * infcmd.c -- insert else to avoid 'delete env' coredump when you
        delete the whole environment.  Karl Berry reported the bug.
        * source.c - fix openp to avoid //'s in filenames, which
        trigger an Emacs bug causing it to not be able to find files
        when running gdb in a window.
        * dbxread.c - zap the #if 0 that botches the add-file code.
        It seems to work a lot better without all the code commented out.

Fri Jul 20 16:58:46 1990  John Gilmore  (gnu at cygnus.com)

        * Merge Tiemann's and Ted Goldstein's changes, detailed below,
        into gdb-3.90.9.

Tue Jul 17 19:34:33 1990  Ted Goldstein  (tedg at golem)

        * Makefile - added a ${CFLAGS} to a couple of entries,
        added remote-sa.sparc.c
        * added remote.sa-sparc.c, a modification of remote.c
        which conducts a dialog directly with the SparcStation prom.
        * breakpoint.c, infrun.c, sparcdep.c  added 
        remote_insert_breakpoint(), and remote_remove_breakpoint() 
        to breakpoint.c instead of directly writing breakpoint instructions.
        * sparcdep.c on remote_debugging,there is no need 
        to remove signle step breakpoint instructions.
        * main.c added "-epoch" flag and "int epoch_interface" to main.c
        global variable
        * printcmd.c - epoch interface sends lisp expressions to open up
        epoch windows on inspection.
        * valprint.c - added arrayprint, and addressprint and made adding
        format controls easier
        * wait.h added a couple of undef's because we were getting
        complaints about WSTOPSIG and WTERMSIG begin redefined.


Wed Jul  4 05:27:51 1990  Michael Tiemann  (tiemann at masham)

        * symtab.c (decode_line_1): Add support for handling method stubs
        in the type information.

Tue Jul  3 09:39:18 1990  Michael Tiemann  (tiemann at masham)

        * values.c (baseclass_addr): Run loop from INDEX+1 to
        N_BASECLASSES; otherwise, we can still get into a loop.
        @@ This should be restructured to use a cleaner search strategy.

Sun Jul  1 12:28:51 1990  Michael Tiemann  (tiemann at masham)

        * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
        abbreviation "Tt" for tags which have the same name as their
        typedecls.

Fri Jun 29 01:03:46 1990  Michael Tiemann  (tiemann at masham)

        * symtab.c (list_symbols): add ability to set breakpoints on all
        the functions which match a particular regular expression.

Tue Jun 26 04:26:29 1990  Michael Tiemann  (tiemann at masham)

        * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
        should print ANSI qualifiers (such as `const' and `volatile').
        All callers changed to call with ANSI == 1, except from
        `check_method_stub', which uses old-style syntax.

        * symseg.h (struct fn_field): Remove unneccessary `args' field.
        * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.

        * values.c (check_stub_method): New function.

        * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').

        * dbxread.c (read_type): Handle new GNU C++ method type stubs.
        * valprint (type_print_base): Ditto.

        * symtab.c (gdb_mangle_typename): New function.

Tue Jun  5 00:18:43 1990  Michael Tiemann  (tiemann at gzilla)

        * breakpoint.c (catch_command): New function.  Provides a
        mechanism to set breakpoints based on catch clauses.
        (disable_catch): Similar, but disables breakpoints on catch
        clauses.
        (delete_catch): Similar, but deleted breakpoints on catch clauses.
