You must call this subroutine explicitly near the +beginning of your program. + +@item handle_exception +@kindex handle_exception +@cindex remote serial stub, main routine +This is the central workhorse, but your program never calls it +explicitly---the setup code arranges for @code{handle_exception} to +run when a trap is triggered. + +@code{handle_exception} takes control when your program stops during +execution (for example, on a breakpoint), and mediates communications +with @value{GDBN} on the host machine. This is where the communications +protocol is implemented; @code{handle_exception} acts as the @value{GDBN} +representative on the target machine; it begins by sending summary +information on the state of your program, then continues to execute, +retrieving and transmitting any information @value{GDBN} needs, until you +execute a @value{GDBN} command that makes your program resume; at that point, +@code{handle_exception} returns control to your own code on the target +machine. + +@item breakpoint +@cindex @code{breakpoint} subroutine, remote +Use this auxiliary subroutine to make your program contain a +breakpoint. Depending on the particular situation, this may be the only +way for @value{GDBN} to get control. For instance, if your target +machine has some sort of interrupt button, you won't need to call this; +pressing the interrupt button transfers control to +@code{handle_exception}---in effect, to @value{GDBN}. On some machines, +simply receiving characters on the serial port may also trigger a trap; +again, in that situation, you don't need to call @code{breakpoint} from +your own program---simply running @samp{target remote} from the host +@value{GDBN} session gets control. + +Call @code{breakpoint} if none of these is true, or if you simply want +to make certain your program stops at a predetermined point for the +start of your debugging session. +@end table + +@node Bootstrapping +@subsubsection What you must do for the stub + +@cindex remote stub, support routines +The debugging stubs that come with @value{GDBN} are set up for a particular +chip architecture, but they have no information about the rest of your +debugging target machine. + +First of all you need to tell the stub how to communicate with the +serial port. + +@table @code +@item int getDebugChar() +@kindex getDebugChar +Write this subroutine to read a single character from the serial port. +It may be identical to @code{getchar} for your target system; a +different name is used to allow you to distinguish the two if you wish. + +@item void putDebugChar(int) +@kindex putDebugChar +Write this subroutine to write a single character to the serial port. +It may be identical to @code{putchar} for your target system; a +different name is used to allow you to distinguish the two if you wish. +@end table + +@cindex control C, and remote debugging +@cindex interrupting remote targets +If you want @value{GDBN} to be able to stop your program while it is +running, you need to use an interrupt-driven serial driver, and arrange +for it to stop when it receives a @code{^C} (@samp{\003}, the control-C +character). That is the character which @value{GDBN} uses to tell the +remote system to stop. + +Getting the debugging target to return the proper status to @value{GDBN} +probably requires changes to the standard stub; one quick and dirty way +is to just execute a breakpoint instruction (the ``dirty'' part is that +@value{GDBN} reports a @code{SIGTRAP} instead of a @code{SIGINT}). + +Other routines you need to supply are: + +@table @code +@item void exceptionHandler (int @var{exception_number}, void *@var{exception_address}) +@kindex exceptionHandler +Write this function to install @var{exception_address} in the exception +handling tables. You need to do this because the stub does not have any +way of knowing what the exception handling tables on your target system +are like (for example, the processor's table might be in @sc{rom}, +containing entries which point to a table in @sc{ram}). +@var{exception_number} is the exception number which should be changed; +its meaning is architecture-dependent (for example, different numbers +might represent divide by zero, misaligned access, etc). When this +exception occurs, control should be transferred directly to +@var{exception_address}, and the processor state (stack, registers, +and so on) should be just as it is when a processor exception occurs. So if +you want to use a jump instruction to reach @var{exception_address}, it +should be a simple jump, not a jump to subroutine. + +For the 386, @var{exception_address} should be installed as an interrupt +gate so that interrupts are masked while the handler runs. The gate +should be at privilege level 0 (the most privileged level). The +@sc{sparc} and 68k stubs are able to mask interrupts themselves without +help from @code{exceptionHandler}. + +@item void flush_i_cache() +@kindex flush_i_cache +(sparc and sparclite only) Write this subroutine to flush the +instruction cache, if any, on your target machine. If there is no +instruction cache, this subroutine may be a no-op. + +On target machines that have instruction caches, @value{GDBN} requires this +function to make certain that the state of your program is stable. +@end table + +@noindent +You must also make sure this library routine is available: + +@table @code +@item void *memset(void *, int, int) +@kindex memset +This is the standard library function @code{memset} that sets an area of +memory to a known value.

This may or may not succeed, depending in part on the hardware +and the serial drivers the remote system uses.

Beyond that its meaning is poorly defined. +@value{GDBN} is not known to output @var{sequence-id}s. + +When either the host or the target machine receives a packet, the first +response expected is an acknowledgment: either @samp{+} (to indicate +the package was received correctly) or @samp{-} (to request +retransmission): + +@example +<- @code{$}@var{packet-data}@code{#}@var{checksum} +-> @code{+} +@end example +@noindent +If the received packet included a @var{sequence-id} than that is +appended to a positive acknowledgment: + +@example +<- @code{$}@var{sequence-id}@code{:}@var{packet-data}@code{#}@var{checksum} +-> @code{+}@var{sequence-id} +@end example + +The host (@value{GDBN}) sends @var{command}s, and the target (the +debugging stub incorporated in your program) sends a @var{response}. In +the case of step and continue @var{command}s, the response is only sent +when the operation has completed (the target has again stopped). + +@var{packet-data} consists of a sequence of characters with the +exception of @samp{#} and @samp{$} (see @samp{X} packet for an +exception). @samp{:} can not appear as the third character in a packet. +Fields within the packet should be separated using @samp{,} and @samp{;} +(unfortunately some packets chose to use @samp{:}). Except where +otherwise noted all numbers are represented in HEX with leading zeros +suppressed. + +Response @var{data} can be run-length encoded to save space. A @samp{*} +means that the next character is an ASCII encoding giving a repeat count +which stands for that many repetitions of the character preceding the +@samp{*}. The encoding is @code{n+29}, yielding a printable character +where @code{n >=3} (which is where rle starts to win).

In fact, a system that can run +@code{gdbserver} to connect to a remote @value{GDBN} could also run +@value{GDBN} locally! @code{gdbserver} is sometimes useful nevertheless, +because it is a much smaller program than @value{GDBN} itself. It is +also easier to port than all of @value{GDBN}, so you may be able to get +started more quickly on a new system by using @code{gdbserver}. +Finally, if you develop code for real-time systems, you may find that +the tradeoffs involved in real-time operation make it more convenient to +do as much development work as possible on another system, for example +by cross-compiling. You can use @code{gdbserver} to make a similar +choice for debugging. + +@value{GDBN} and @code{gdbserver} communicate via either a serial line +or a TCP connection, using the standard @value{GDBN} remote serial +protocol. + +@table @emph +@item On the target machine, +you need to have a copy of the program you want to debug. +@code{gdbserver} does not need your program's symbol table, so you can +strip the program if necessary to save space. @value{GDBN} on the host +system does all the symbol handling. + +To use the server, you must tell it how to communicate with @value{GDBN}; +the name of your program; and the arguments for your program. The +syntax is: + +@smallexample +target> gdbserver @var{comm} @var{program} [ @var{args} @dots{} ] +@end smallexample + +@var{comm} is either a device name (to use a serial line) or a TCP +hostname and portnumber. For example, to debug Emacs with the argument +@samp{foo.txt} and communicate with @value{GDBN} over the serial port +@file{/dev/com1}: + +@smallexample +target> gdbserver /dev/com1 emacs foo.txt +@end smallexample + +@code{gdbserver} waits passively for the host @value{GDBN} to communicate +with it. +To use a TCP connection instead of a serial line: + +@smallexample +target> gdbserver host:2345 emacs foo.txt +@end smallexample + +The only difference from the previous example is the first argument, +specifying that you are communicating with the host @value{GDBN} via +TCP. The @samp{host:2345} argument means that @code{gdbserver} is to +expect a TCP connection from machine @samp{host} to local TCP port 2345. +(Currently, the @samp{host} part is ignored.) You can choose any number +you want for the port number as long as it does not conflict with any +TCP ports already in use on the target system (for example, @code{23} is +reserved for @code{telnet}).@footnote{If you choose a port number that +conflicts with another service, @code{gdbserver} prints an error message +and exits.} You must use the same port number with the host @value{GDBN} +@code{target remote} command. + +@item On the @value{GDBN} host machine, +you need an unstripped copy of your program, since @value{GDBN} needs +symbols and debugging information. Start up @value{GDBN} as usual, +using the name of the local copy of your program as the first argument. +(You may also need the @w{@samp{--baud}} option if the serial line is +running at anything other than 9600 bps.) After that, use @code{target +remote} to establish communications with @code{gdbserver}. Its argument +is either a device name (usually a serial device, like +@file{/dev/ttyb}), or a TCP port descriptor in the form +@code{@var{host}:@var{PORT}}. For example: + +@smallexample +(@value{GDBP}) target remote /dev/ttyb +@end smallexample + +@noindent +communicates with the server via serial line @file{/dev/ttyb}, and + +@smallexample +(@value{GDBP}) target remote the-target:2345 +@end smallexample + +@noindent +communicates via a TCP connection to port 2345 on host @w{@file{the-target}}. +For TCP connections, you must start up @code{gdbserver} prior to using +the @code{target remote} command.

The object file given as an argument to the @code{load} +command is actually opened twice: first by the VxWorks target in order +to download the code, then by @value{GDBN} in order to read the symbol +table. This can lead to problems if the current working directories on +the two systems differ. If both systems have NFS mounted the same +filesystems, you can avoid these problems by using absolute paths. +Otherwise, it is simplest to set the working directory on both systems +to the directory in which the object file resides, and then to reference +the file by its name, without any path. For instance, a program +@file{prog.o} may reside in @file{@var{vxpath}/vw/demo/rdb} in VxWorks +and in @file{@var{hostpath}/vw/demo/rdb} on the host. To load this +program, type this on VxWorks: + +@example +-> cd "@var{vxpath}/vw/demo/rdb" +@end example +v +Then, in @value{GDBN}, type: + +@example +(vxgdb) cd @var{hostpath}/vw/demo/rdb +(vxgdb) load prog.o +@end example + +@value{GDBN} displays a response similar to this: + +@smallexample +Reading symbol data from wherever/vw/demo/rdb/prog.o... done. +@end smallexample + +You can also use the @code{load} command to reload an object module +after editing and recompiling the corresponding source file. Note that +this makes @value{GDBN} delete all currently-defined breakpoints, +auto-displays, and convenience variables, and to clear the value +history.
