-		   README for GDBserver & GDBreplay
-		    by Stu Grossman and Fred Fish
-
-Introduction:
-
-This is GDBserver, a remote server for Un*x-like systems.  It can be used to
-control the execution of a program on a target system from a GDB on a different
-host.  GDB and GDBserver communicate using the standard remote serial protocol
-implemented in remote.c, and various *-stub.c files.  They communicate via
-either a serial line or a TCP connection.
-
-For more information about GDBserver, see the GDB manual.
-
-Usage (server (target) side):
-
-First, you need to have a copy of the program you want to debug put onto
-the target system.  The program can be stripped to save space if needed, as
-GDBserver doesn't care about symbols.  All symbol handling is taken care of by
-the GDB running on the host system.
-
-To use the server, you log on to the target system, and run the `gdbserver'
-program.  You must tell it (a) how to communicate with GDB, (b) the name of
-your program, and (c) its arguments.  The general syntax is:
-
-	target> gdbserver COMM PROGRAM [ARGS ...]
-
-For example, using a serial port, you might say:
-
-	target> gdbserver /dev/com1 emacs foo.txt
-
-This tells GDBserver to debug emacs with an argument of foo.txt, and to
-communicate with GDB via /dev/com1.  GDBserver now waits patiently for the
-host GDB to communicate with it.
-
-To use a TCP connection, you could say:
-
-	target> gdbserver host:2345 emacs foo.txt
-
-This says pretty much the same thing as the last example, except that we are
-going to communicate with the host GDB via TCP.  The `host:2345' argument means
-that we are expecting to see a TCP connection from `host' to local TCP port
-2345.  (Currently, the `host' part is ignored.)  You can choose any number you
-want for the port number as long as it does not conflict with any existing TCP
-ports on the target system.  This same port number must be used in the host
-GDBs `target remote' command, which will be described shortly.  Note that if
-you chose a port number that conflicts with another service, GDBserver will
-print an error message and exit.
-
-On some targets, GDBserver can also attach to running programs.  This is
-accomplished via the --attach argument.  The syntax is:
-
-	target> gdbserver --attach COMM PID
-
-PID is the process ID of a currently running process.  It isn't necessary
-to point GDBserver at a binary for the running process.
-
-Usage (host side):
-
-You need an unstripped copy of the target program on your host system, since
-GDB needs to examine it's symbol tables and such.  Start up GDB as you normally
-would, with the target program as the first argument.  (You may need to use the
---baud option if the serial line is running at anything except 9600 baud.)
-Ie: `gdb TARGET-PROG', or `gdb --baud BAUD TARGET-PROG'.  After that, the only
-new command you need to know about is `target remote'.  It's argument is either
-a device name (usually a serial device, like `/dev/ttyb'), or a HOST:PORT
-descriptor.  For example:
-
-	(gdb) target remote /dev/ttyb
-
-communicates with the server via serial line /dev/ttyb, and:
-
-	(gdb) target remote the-target:2345
-
-communicates via a TCP connection to port 2345 on host `the-target', where
-you previously started up GDBserver with the same port number.  Note that for
-TCP connections, you must start up GDBserver prior to using the `target remote'
-command, otherwise you may get an error that looks something like
-`Connection refused'.
-
-Building GDBserver:
-
-The supported targets as of November 2006 are:
-	arm-*-linux*
-	bfin-*-uclinux
-	bfin-*-linux-uclibc
-	crisv32-*-linux*
-	cris-*-linux*
-	i[34567]86-*-cygwin*
-	i[34567]86-*-linux*
-	i[34567]86-*-mingw*
-	ia64-*-linux*
-	m32r*-*-linux*
-	m68*-*-linux*
-	m68*-*-uclinux*
-	mips*64*-*-linux*
-	mips*-*-linux*
-	powerpc[64]-*-linux*
-	s390[x]-*-linux*
-	sh-*-linux*
-	spu*-*-*
-	x86_64-*-linux*
-
-Configuring GDBserver you should specify the same machine for host and
-target (which are the machine that GDBserver is going to run on.  This
-is not the same as the machine that GDB is going to run on; building
-GDBserver automatically as part of building a whole tree of tools does
-not currently work if cross-compilation is involved (we don't get the
-right CC in the Makefile, to start with)).
-
-Building GDBserver for your target is very straightforward.  If you build
-GDB natively on a target which GDBserver supports, it will be built
-automatically when you build GDB.  You can also build just GDBserver:
-
-	% mkdir obj
-	% cd obj
-	% path-to-gdbserver-sources/configure
-	% make
-
-If you prefer to cross-compile to your target, then you can also build
-GDBserver that way.  In a Bourne shell, for example:
-
-	% export CC=your-cross-compiler
-	% path-to-gdbserver-sources/configure your-target-name
-	% make
-
-Using GDBreplay:
-
-A special hacked down version of GDBserver can be used to replay remote
-debug log files created by GDB.  Before using the GDB "target" command to
-initiate a remote debug session, use "set remotelogfile <filename>" to tell
-GDB that you want to make a recording of the serial or tcp session.  Note
-that when replaying the session, GDB communicates with GDBreplay via tcp,
-regardless of whether the original session was via a serial link or tcp.
-
-Once you are done with the remote debug session, start GDBreplay and
-tell it the name of the log file and the host and port number that GDB
-should connect to (typically the same as the host running GDB):
-
-	$ gdbreplay logfile host:port
-
-Then start GDB (preferably in a different screen or window) and use the
-"target" command to connect to GDBreplay:
-
-	(gdb) target remote host:port
-
-Repeat the same sequence of user commands to GDB that you gave in the
-original debug session.  GDB should not be able to tell that it is talking
-to GDBreplay rather than a real target, all other things being equal.  Note
-that GDBreplay echos the command lines to stderr, as well as the contents of
-the packets it sends and receives.  The last command echoed by GDBreplay is
-the next command that needs to be typed to GDB to continue the session in
-sync with the original session.

-\`configure' configures this package to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-

-.TH gdbserver 1 "2 November 1993" "Cygnus Support" "GNU Development Tools"
-.SH NAME
-gdbserver \- Remote Server for the GNU Debugger
-.SH SYNOPSIS
-.na
-.TP
-.B gdbserver
-.RB tty
-.RB prog
-.RB "[\|" args... "\|]"

-.B gdbserver

-.SH DESCRIPTION
-GDBSERVER is a program that allows you to run GDB on a different machine
-than the one which is running the program being debugged.
-
-Usage (server (target) side):
-
-First, you need to have a copy of the program you want to debug put onto
-the target system.  The program can be stripped to save space if needed, as
-GDBserver doesn't care about symbols.  All symbol handling is taken care of by
-the GDB running on the host system.
-
-To use the server, you log on to the target system, and run the `gdbserver'
-program.  You must tell it (a) how to communicate with GDB, (b) the name of
-your program, and (c) its arguments.  The general syntax is:
-
-	target> gdbserver COMM PROGRAM [ARGS ...]
-
-For example, using a serial port, you might say:
-
-	target> gdbserver /dev/com1 emacs foo.txt
-
-This tells gdbserver to debug emacs with an argument of foo.txt, and to
-communicate with GDB via /dev/com1.  Gdbserver now waits patiently for the
-host GDB to communicate with it.
-
-To use a TCP connection, you could say:
-
-	target> gdbserver host:2345 emacs foo.txt
-
-This says pretty much the same thing as the last example, except that we are
-going to communicate with the host GDB via TCP.  The `host:2345' argument means
-that we are expecting to see a TCP connection from `host' to local TCP port
-2345.  (Currently, the `host' part is ignored.)  You can choose any number you
-want for the port number as long as it does not conflict with any existing TCP
-ports on the target system.  This same port number must be used in the host
-GDBs `target remote' command, which will be described shortly.  Note that if
-you chose a port number that conflicts with another service, gdbserver will
-print an error message and exit.
-
-On some targets, gdbserver can also attach to running programs.
-This is accomplished via the --attach argument.  The syntax is:
-
-	target> gdbserver COMM --attach PID
-
-PID is the process ID of a currently running process.  It isn't
-necessary to point gdbserver at a binary for the running process.
-
-Usage (host side):
-
-You need an unstripped copy of the target program on your host system, since
-GDB needs to examine it's symbol tables and such.  Start up GDB as you normally
-would, with the target program as the first argument.  (You may need to use the
---baud option if the serial line is running at anything except 9600 baud.)
-Ie: `gdb TARGET-PROG', or `gdb --baud BAUD TARGET-PROG'.  After that, the only
-new command you need to know about is `target remote'.  It's argument is either
-a device name (usually a serial device, like `/dev/ttyb'), or a HOST:PORT
-descriptor.  For example:
-
-	(gdb) target remote /dev/ttyb
-
-communicates with the server via serial line /dev/ttyb, and:
-
-	(gdb) target remote the-target:2345
-
-communicates via a TCP connection to port 2345 on host `the-target', where
-you previously started up gdbserver with the same port number.  Note that for
-TCP connections, you must start up gdbserver prior to using the `target remote'
-command, otherwise you may get an error that looks something like
-`Connection refused'.
-.SH OPTIONS
-You have to supply the name of the program to debug
-and the tty to communicate on; the remote GDB will do everything else.
-Any remaining arguments will be passed to the program verbatim.

-
-     2) This is the first thread (the process thread), and we're attaching
-	to it via attach_inferior.
-	In this case we want the process thread to stop.
-	This is handled by having linux_attach set last_resume_kind ==
-	resume_stop after we return.
-
-	If the pid we are attaching to is also the tgid, we attach to and
-	stop all the existing threads.  Otherwise, we attach to pid and
-	ignore any other threads in the same group as this pid.
-
-     3) GDB is connecting to gdbserver and is requesting an enumeration of all
-	existing threads.
-	In this case we want the thread to stop.
-	FIXME: This case is currently not properly handled.
-	We should wait for the SIGSTOP but don't.  Things work apparently
-	because enough time passes between when we ptrace (ATTACH) and when
-	gdb makes the next ptrace call on the thread.
-
-     On the other hand, if we are currently trying to stop all threads, we
-     should treat the new thread as if we had sent it a SIGSTOP.  This works
-     because we are guaranteed that the add_lwp call above added us to the

-
-   This avoids recursion while collecting (when a signal arrives
-   midway, and the signal handler itself collects), which would trash
-   the trace buffer.  In case the user set a breakpoint in a signal
-   handler, this avoids the backtrace showing the jump pad, etc..
-   Most importantly, there are certain things we can't do safely if
-   threads are stopped in a jump pad (or in its callee's).  For
-   example:
-
-     - starting a new trace run.  A thread still collecting the
-   previous run, could trash the trace buffer when resumed.  The trace
-   buffer control structures would have been reset but the thread had
-   no way to tell.  The thread could even midway memcpy'ing to the
-   buffer, which would mean that when resumed, it would clobber the
-   trace buffer that had been set for a new run.
-
-     - we can't rewrite/reuse the jump pads for new tracepoints
-   safely.  Say you do tstart while a thread is stopped midway while
-   collecting.  When the thread is later resumed, it finishes the
-   collection, and returns to the jump pad, to execute the original
-   instruction that was under the tracepoint jump at the time the
-   older run had been started.  If the jump pad had been rewritten
-   since for something else in the new run, the thread would now
-   execute the wrong / random instructions.  */

-   `inserted' state associated with this low level breakpoint
-   structure.  There can only be one such object for a given address.
-   Then, we have (a bit higher level) breakpoints.  This structure
-   holds a callback to be called whenever a breakpoint is hit, a
-   high-level type, and a link to a low level raw breakpoint.  There

-/* This file is built for both GDBserver, and the in-process
-   agent (IPA), a shared library that includes a tracing agent that is
-   loaded by the inferior to support fast tracepoints.  Fast
-   tracepoints (or more accurately, jump based tracepoints) are
-   implemented by patching the tracepoint location with a jump into a
-   small trampoline function whose job is to save the register state,
-   call the in-process tracing agent, and then execute the original
-   instruction that was under the tracepoint jump (possibly adjusted,
-   if PC-relative, or some such).
-
-   The current synchronization design is pull based.  That means,
-   GDBserver does most of the work, by peeking/poking at the inferior
-   agent's memory directly for downloading tracepoint and associated
-   objects, and for uploading trace frames.  Whenever the IPA needs
-   something from GDBserver (trace buffer is full, tracing stopped for
-   some reason, etc.) the IPA calls a corresponding hook function
-   where GDBserver has placed a breakpoint.
-
-   Each of the agents has its own trace buffer.  When browsing the
-   trace frames built from slow and fast tracepoints from GDB (tfind
-   mode), there's no guarantee the user is seeing the trace frames in
-   strict chronological creation order, although, GDBserver tries to
-   keep the order relatively reasonable, by syncing the trace buffers
-   at appropriate times.

-/* We have possibly both GDBserver and an inferior thread accessing
-   the same IPA trace buffer memory.  The IPA is the producer (tries
-   to put new frames in the buffer), while GDBserver occasionally
-   consumes them, that is, flushes the IPA's buffer into its own
-   buffer.  Both sides need to update the trace buffer control
-   pointers (current head, tail, etc.).  We can't use a global lock to
-   synchronize the accesses, as otherwise we could deadlock GDBserver
-   (if the thread holding the lock stops for a signal, say).  So
-   instead of that, we use a transaction scheme where GDBserver writes
-   always prevail over the IPAs writes, and, we have the IPA detect
-   the commit failure/overwrite, and retry the whole attempt.  This is
-   mainly implemented by having a global token object that represents
-   who wrote last to the buffer control structure.  We need to freeze
-   any inferior writing to the buffer while GDBserver touches memory,
-   so that the inferior can correctly detect that GDBserver had been
-   there, otherwise, it could mistakingly think its commit was
-   successful; that's implemented by simply having GDBserver set a
-   breakpoint the inferior hits if it is the critical region.
-
-   There are three cycling trace buffer control structure copies
-   (buffer head, tail, etc.), with the token object including an index
-   indicating which is current live copy.  The IPA tentatively builds
-   an updated copy in a non-current control structure, while GDBserver
-   always clobbers the current version directly.  The IPA then tries
-   to atomically "commit" its version; if GDBserver clobbered the
-   structure meanwhile, that will fail, and the IPA restarts the
-   allocation process.
-
-   Listing the step in further detail, we have:
-
-  In-process agent (producer):
-
-  - passes by `about_to_request_buffer_space' breakpoint/lock
-
-  - reads current token, extracts current trace buffer control index,
-    and starts tentatively updating the rightmost one (0->1, 1->2,
-    2->0).  Note that only one inferior thread is executing this code
-    at any given time, due to an outer lock in the jump pads.
-
-  - updates counters, and tries to commit the token.
-
-  - passes by second `about_to_request_buffer_space' breakpoint/lock,
-    leaving the sync region.
-
-  - checks if the update was effective.
-
-  - if trace buffer was found full, hits flush_trace_buffer
-    breakpoint, and restarts later afterwards.
-
-  GDBserver (consumer):
-
-  - sets `about_to_request_buffer_space' breakpoint/lock.
-
-  - updates the token unconditionally, using the current buffer
-    control index, since it knows that the IP agent always writes to
-    the rightmost, and due to the breakpoint, at most one IP thread
-    can try to update the trace buffer concurrently to GDBserver, so
-    there will be no danger of trace buffer control index wrap making
-    the IPA write to the same index as GDBserver.
-
-  - flushes the IP agent's trace buffer completely, and updates the
-    current trace buffer control structure.  GDBserver *always* wins.
-
-  - removes the `about_to_request_buffer_space' breakpoint.
-
-The token is stored in the `trace_buffer_ctrl_curr' variable.
-Internally, it's bits are defined as:
-
- |-------------+-----+-------------+--------+-------------+--------------|
- | Bit offsets |  31 |   30 - 20   |   19   |    18-8     |     7-0      |
- |-------------+-----+-------------+--------+-------------+--------------|
- | What        | GSB | PC (11-bit) | unused | CC (11-bit) | TBCI (8-bit) |
- |-------------+-----+-------------+--------+-------------+--------------|
-
- GSB  - GDBserver Stamp Bit
- PC   - Previous Counter
- CC   - Current Counter
- TBCI - Trace Buffer Control Index
-
-
-An IPA update of `trace_buffer_ctrl_curr' does:
-
-    - read CC from the current token, save as PC.
-    - updates pointers
-    - atomically tries to write PC+1,CC
-
-A GDBserver update of `trace_buffer_ctrl_curr' does:
-
-    - reads PC and CC from the current token.
-    - updates pointers
-    - writes GSB,PC,CC
