-
-@table @code
-@item rdilogfile @r{[}@var{file}@r{]}
-@kindex rdilogfile
-@cindex ADP (Angel Debugger Protocol) logging
-Set the filename for the ADP (Angel Debugger Protocol) packet log.
-With an argument, sets the log file to the specified @var{file}. With
-no argument, show the current log file name. The default log file is
-@file{rdi.log}.
-
-@item rdilogenable @r{[}@var{arg}@r{]}
-@kindex rdilogenable
-Control logging of ADP packets. With an argument of 1 or @code{"yes"}
-enables logging, with an argument 0 or @code{"no"} disables it. With
-no arguments displays the current setting. When logging is enabled,
-ADP packets exchanged between @value{GDBN} and the RDI target device
-are logged to a file.
-
-@item set rdiromatzero
-@kindex set rdiromatzero
-@cindex ROM at zero address, RDI
-Tell @value{GDBN} whether the target has ROM at address 0. If on,
-vector catching is disabled, so that zero address can be used. If off
-(the default), vector catching is enabled. For this command to take
-effect, it needs to be invoked prior to the @code{target rdi} command.
-
-@item show rdiromatzero
-@kindex show rdiromatzero
-Show the current setting of ROM at zero address.
-
-@item set rdiheartbeat
-@kindex set rdiheartbeat

-Enable or disable RDI heartbeat packets. It is not recommended to
-turn on this option, since it confuses ARM and EPI JTAG interface, as
-well as the Angel monitor.

-
-@cindex compiling, on Sparclet
-When compiling for debugging, include the options @samp{-g} to get debug
-information and @samp{-Ttext} to relocate the program to where you wish to
-load it on the target. You may also want to add the options @samp{-n} or
-@samp{-N} in order to reduce the size of the sections. Example:
-
-@smallexample
-sparclet-aout-gcc prog.c -Ttext 0x12010000 -g -o prog -N
-@end smallexample
-
-You can use @code{objdump} to verify that the addresses are what you intended:
-
-@smallexample
-sparclet-aout-objdump --headers --syms prog
-@end smallexample
-
-@cindex running, on Sparclet
-Once you have set
-your Unix execution search path to find @value{GDBN}, you are ready to
-run @value{GDBN}. From your Unix host, run @code{@value{GDBP}}
-(or @code{sparclet-aout-gdb}, depending on your installation).
-
-@value{GDBN} comes up showing the prompt:

-@node Sparclet File
-@subsubsection Setting File to Debug
-
-The @value{GDBN} command @code{file} lets you choose with program to debug.
-
-@smallexample
-(gdbslet) file prog
-@end smallexample
-
-@need 1000
-@value{GDBN} then attempts to read the symbol table of @file{prog}.
-@value{GDBN} locates
-the file by searching the directories listed in the command search
-path.
-If the file was compiled with debug information (option @samp{-g}), source
-files will be searched as well.
-@value{GDBN} locates
-the source files by searching the directories listed in the directory search
-path (@pxref{Environment, ,Your Program's Environment}).
-If it fails
-to find a file, it displays a message such as:
-
-@smallexample
-prog: No such file or directory.
-@end smallexample
-
-When this happens, add the appropriate directories to the search paths with
-the @value{GDBN} commands @code{path} and @code{dir}, and execute the
-@code{target} command again.
-
-@node Sparclet Connection
-@subsubsection Connecting to Sparclet
-
-The @value{GDBN} command @code{target} lets you connect to a Sparclet target.
-To connect to a target on serial port ``@code{ttya}'', type:
-
-@smallexample
-(gdbslet) target sparclet /dev/ttya
-Remote target sparclet connected to /dev/ttya
-main () at ../prog.c:3
-@end smallexample
-
-@need 750
-@value{GDBN} displays messages like these:
-
-@smallexample
-Connected to ttya.
-@end smallexample
-
-@node Sparclet Download
-@subsubsection Sparclet Download
-
-@cindex download to Sparclet
-Once connected to the Sparclet target,
-you can use the @value{GDBN}
-@code{load} command to download the file from the host to the target.
-The file name and load offset should be given as arguments to the @code{load}
-command.
-Since the file format is aout, the program must be loaded to the starting
-address. You can use @code{objdump} to find out what this value is. The load
-offset is an offset which is added to the VMA (virtual memory address)
-of each of the file's sections.
-For instance, if the program
-@file{prog} was linked to text address 0x1201000, with data at 0x12010160
-and bss at 0x12010170, in @value{GDBN}, type:
-
-@smallexample
-(gdbslet) load prog 0x12010000
-Loading section .text, size 0xdb0 vma 0x12010000
-@end smallexample
-
-If the code is loaded at a different address then what the program was linked
-to, you may need to use the @code{section} and @code{add-symbol-file} commands
-to tell @value{GDBN} where to map the symbol table.
-
-@node Sparclet Execution
-@subsubsection Running and Debugging
-
-@cindex running and debugging Sparclet programs
-You can now begin debugging the task using @value{GDBN}'s execution control
-commands, @code{b}, @code{step}, @code{run}, etc. See the @value{GDBN}
-manual for the list of commands.
-
-@smallexample
-(gdbslet) b main
-Breakpoint 1 at 0x12010000: file prog.c, line 3.
-(gdbslet) run
-Starting program: prog
-Breakpoint 1, main (argc=1, argv=0xeffff21c) at prog.c:3

-
-When configured for debugging Zilog Z8000 targets, @value{GDBN} includes
-a Z8000 simulator.
-
-For the Z8000 family, @samp{target sim} simulates either the Z8002 (the
-unsegmented variant of the Z8000 architecture) or the Z8001 (the
-segmented variant). The simulator recognizes which architecture is
-appropriate by inspecting the object code.
-
-@table @code
-@item target sim @var{args}
-@kindex sim
-@kindex target sim@r{, with Z8000}
-Debug programs on a simulated CPU. If the simulator supports setup
-options, specify them via @var{args}.
-@end table
-
-@noindent
-After specifying this target, you can debug programs for the simulated
-CPU in the same style as programs for your host computer; use the
-@code{file} command to load a new program image, the @code{run} command
-to run your program, and so on.
-
-As well as making available all the usual machine registers
-(@pxref{Registers, ,Registers}), the Z8000 simulator provides three
-additional items of information as specially named registers:
-
-@table @code
-
-@item cycles
-Counts clock-ticks in the simulator.
-
-@item insts
-Counts instructions run in the simulator.
-
-@item time
-Execution time in 60ths of a second.
-
-@end table
-
-You can refer to these values in @value{GDBN} expressions with the usual
-conventions; for example, @w{@samp{b fputc if $cycles>5000}} sets a
-conditional breakpoint that suspends only after at least 5000
-simulated clock ticks.
