-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

- *
- * $Revision$
- * $Date$
- *
- *
- *
- * INTRODUCTION
- * ------------
- * The early RDP message definitions were held in an ARM Ltd "armdbg"
- * source file. Since the relevant header files were not exported
- * publicly as part of an ARM Ltd core tools release, it was a problem
- * for developers manipulating the target side of the protocol.
- *
- * For Angel, this new (ANSI 'C' clean) header file defines the ADP
- * protocol. The header should be useable by both host and target
- * systems, thus avoiding problems that can arise from duplicate
- * definitions. Care has been taken in the construction of this header
- * file to avoid any host/target differences.
- *
- * MESSAGE FORMAT
- * --------------
- * Format of the "data" section of debug and boot agent messages. This is
- * the standard ADP (Angel Debug Protocol) message format:
- *
- * unsigned32 reason - Main debug reason code.
- * unsigned32 debugID - Information describing host debug world;
- * - private to host and used in any target initiated
- * messages.
- * unsigned32 OSinfo1 \ Target OS information to identify process/thread
- * unsigned32 OSinfo2 / memory/world, etc. These two fields are target
- * defined.
- * byte args[n] - Data for message "reason" code.
- *
- * NOTE: The message format is the same for single threaded debugging,
- * except that the "OSinfo" fields should be -1 (0xFFFFFFFF). Even
- * single-threaded debugging *MAY* have different host specified
- * debugID values, so the Angel debug system will preserve the "debugID"
- * information for replies, and the relevant asynchronous target-to-host
- * messages. The "debugID" is defined by the host-end of the
- * protocol, and is used by the host to ensure that messages are
- * routed to the correct handler program/veneer.
- *
- * The reason there are two target specified "OSinfo" words is because
- * thread identifiers may not be unique when processes/tasks have
- * private virtual address spaces. It allows more flexibility when
- * supporting multi-threaded or O/S aware debugging.
- *
- * NOTE: The reason that there is no "size" information, is that the
- * message IDs themselves encode the format of any arguments. Also it
- * would be a duplication of information used by the physical
- * transport layer (which is distinct from this logical message
- * layer). Any routing of messages through programs, hosts,
- * etc. should be performed at the physical layer, or the boundaries
- * between physical layers. i.e. packet received on socket in host,
- * and transferred to serial packet for passing on down the line.
- *
- * NOTE: Pointers aren't passed in messages because they are dangerous in
- * a multi-threaded environment.
- *
- * ADP REASON CODE
- * ---------------
- * The message reason codes contain some information that ties them to
- * the channel and direction that the message will be used with. This
- * will ensure that even if the message "#define name" is not
- * completely descriptive, the message reason code is.
- *
- * b31 = direction. 0=Host-to-Target; 1=Target-to-Host;
- * b30-28 = debug agent multi-threaded control (see below)
- * b27-24 = reserved. should be zero.
- * b23-16 = channelid. The fixed Angel channel number
- * (see "channels.h").
- * b15-0 = message reason code.
- *
- * It is unfortunate that to aid the error-checking capabilities of
- * the Angel communications we have changed the message numbers from
- * the original ARM Ltd RDP. However this also has benefits, in that
- * the Angel work is meant to be a clean break.
- *
- * However, it isn't so bad since even though the numbers are
- * different, the majority of the reason codes have exactly the same
- * functionality as the original RDP messages.
- *
- * NOTES
- * -----
- * It would be ideal to use "rpcgen" (or some equivalent) to
- * automatically maintain compatibility between the target and host
- * ends of the protocol. However, ARM Ltd expressed that the message
- * handling should be hand-coded, to avoid dependance on external
- * tools.
- *
- * All other channels have undefined data formats and are purely
- * application defined. The C library "_sys_" support will provide a
- * veneer to perform message block operations as required.
- *
- * It is IMPLIED that all of the ADP messages will fit within the
- * buffer DATASIZE. This has a minimum value, calculated from
- * BUFFERMINSIZE.
- *
- * All messages are passed and received to the channel system in little
- * endian order (ie. use little endian order when writing a word as
- * a sequence of bytes within a message).
- *
- * A reply / acknowledgement to an ADP message is always sent and has the
- * same reason code as the original except that the TtoH / HtoT bit is
- * reversed. This makes it simple to check that the reply really
- * is a reply to the message which was just sent! [Boot Channel messages
- * also require that this protocol is used].

- * Angel systems with host communications *MUST* provide the BOOT
- * agent, even if they don't have support for either the single- or
- * multi-threaded debug agents.
- *
- * The way the BOOT channel will be used on startup will be as follows:
- *
- * a) Target board is powered up before host debugger is invoked
- *
- * After switching on the target and initialisation is completed the
- * target will send an ADP_Booted or ADP_Reset message. The debugger
- * has not been started yet so this message will not be received. In
- * a serial world this makes it important that any buffers on the host
- * side are flushed during initialisation of the debugger, and in an
- * Ethernet world it makes it important that the target can cope with the
- * message not being received.
- *
- * Eventually the Debugger will be started up and will send an
- * ADP_Reboot or ADP_Reset request. The target will respond to this with
- * an ADP_Reboot or ADP_Reset acknowldege and will then reboot, finally
- * sending an ADP_Rebooted when it has done all it needs to do (very little
- * in the case of ADP_Reset, but completely rebooting in the case of
- * ADP_Reboot). Note that it is important that an ADP_Rebooted message is
- * sent so that the Debugger does not attempt to send any data after it has
- * made a request to ADP_Reboot and before it receives an ADP_Rebooted, as
- * data can be lost be the target during this time.
- *
- * The target and host are now ready to start a debug session.
- *
- * b) Target board is powered up after host debugger is invoked
- *
- * The debugger will send an ADP_Reboot or ADP_Reset request, but will
- * receive no reply until the target is powered up.
-/ *
- * When the target is powered up then it will send an ADP_Rebooted
- * message to the debugger. The debugger should accept this message
- * even though it has received no ADP_Reboot or ADP_Reset acknowldege message
- * from the target.
- *
- * The target and host are now ready to start a debug session.
- *
- *
- * If at any point during the bootup sequence and ADP messages are
- * sent down the S_DBG channel then they should be responded to with a
- * RDI_NotInitialised error. [This should never happen however].
- *
- * An ADP_Boot or ADP Rebooted message should be accepted at
- * any point, since it is possible for a catastrophe to occur (such as
- * disconnecteing the host and target during a debug message) which
- * requires that one or other end be reset.

-/* This header file is the main holder for the declarations and
- * prototypes for the core Angel system. Some Angel concepts are
- * described at the start of this file to ensure that a complete view
- * of the Angel world can be derived purely from the source.
- *
- * $Revision$
- * $Date$
- *
- *
- * NOTE: Currently the Angel source is designed to be simple,
- * understandable and easy to port to new hardware platforms. However,
- * this does not always yield the highest performing system. The
- * current layered approach introduces an overhead to the performance
- * of the system. In a true commercial target, this code should be
- * re-designed to build a system where the Angel logical message
- * system, device driver and hardware accesses are merged to provide
- * the best performance.
- */
-/*---------------------------------------------------------------------------*/
-/* Angel overview:
-
-... some comments describing Angel ...
-
- * Angel is designed as a kit-of-parts that can be used to provide
- * run-time support for the development of ARM applications. The main
- * core of Angel is in providing support for the "debug" message
- * communication with a host system. These messages do not just cover
- * debugging ARM processes, but also the process of downloading ARM
- * programs or attaching to executing processes on the target.
- *
- * A stand-alone ROM based Angel world is the basic starting point for
- * a system, since it will allow programs to be downloaded to the
- * target. The ROM version of Angel will provide the generic debug
- * support, but no system specific routines. The preferred method of
- * using Angel is as a link library. This ensures that applications
- * carry with them the Angel routines necessary to support debugging
- * (and also ensure that the Angel version is up-to-date, independant
- * of the version in the target ROM). Eventually, once a program has
- * been fully debugged, a ROMmed version of the program can be
- * generated with the Angel code being provided in the application.
-
-.. more comments ..
-
- * The standard Angel routines do *NOT* perform any dynamic memory
- * allocation. To simplify the source, and aid the porting to a non C
- * library world, memory is either pre-allocated (as build-time
- * globals) or actually given to the particular Angel routine by the
- * active run-time. This ensures that the interaction between Angel
- * and the target O/S is minimised.
- *
- * Notes: We sub-include more header files to keep the source
- * modular. Since Angel is a kit-of-parts alternative systems may need
- * to change the prototypes of particular functions, whilst
- * maintaining a fixed external interface. e.g. using the standard
- * DEBUG messages, but with a different communications world.

- Wherever an interface is required to iterate over things of some class,
- I prefer something of the form EnumerateXXs(..., XXProc *p, void *arg)
- which results in a call of p(xx, arg) for each xx, rather than something
- of the form
- for (xxh = StartIterationOverXXs(); (xx = Next(xxh)) != 0; ) { ... }
- EndIterationOverXXs(xxh);
- Others may disagree.
- (Each XXProc returns an Error value: if this is not Err_OK, iteration
- stops immediately and the EnumerateXXs function returns that value).
-
- ptrace has been retired as of insufficient utility. If such fuctionality is

-\`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.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --datadir=DIR read-only architecture-independent data [PREFIX/share]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]
- --includedir=DIR C header files [PREFIX/include]

-Optional Features:
- --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
- --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
- --disable-dependency-tracking speeds up one-time build
- --enable-dependency-tracking do not reject slow dependency extractors
- --enable-maintainer-mode enable make rules and dependencies not useful
- (and sometimes confusing) to the casual installer
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
- headers in a nonstandard directory <include dir>
- CPP C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

- * msgbuild
- * --------
- * We use a "varargs" function to enable a description of how the

- *
- * The "buffer" pointer is the starting point from where the data will
- * be written. Note: If a NULL pointer is passed then no data will be
- * written, but the size information will be returned. This allows
- * code to call this routine with a NULL "buffer" pointer to ascertain
- * whether the pointer they are passing contains enough space for the
- * message being constructed.
- *
- * The "format" string should contain sequences of the following
- * tokens:
- * %w - insert 32bit word value
- * %p - insert 32bit target pointer value
- * %h - insert 16bit value
- * %b - insert 8bit byte value

- *
- * MESSAGE FORMAT
- * --------------
- * Format of the "data" section of C Lib Support Channel Messages.
- * You will notice that the format is much the same as the format
- * of ADP messages - this is so that multi-threaded C Libraries can
- * be supported.
- *
- * unsigned32 reason - Main C Library reason code.
- * unsigned32 debugID - Info. describing host debug world;
- * private to host and used in any target
- * initiated messages.
- * unsigned32 OSinfo1 \ Target OS information to identify process/thread
- * unsigned32 OSinfo2 / world, etc. These two fields are target defined.
- * byte args[n] - Data for message "reason" code.
- *
- * The "debugID" is defined by the host-end of the protocol, and is used
- * by the host to ensure that messages are routed to the correct handler
- * program/veneer (eg. imagine several threads having opened stdout and
- * each writing to a different window in a windowed debugger).
- *
- * NOTE: The reason that there is no "size" information, is that the
- * message IDs themselves encode the format of any arguments.
- *
- * For further discussion of the format see adp.h
- *
- * N.B. All streams are little endian.
- *
- * CLIB REASON CODE
- * ----------------
- * The message reason codes contain some information that ties them to
- * the channel and direction that the message will be used with. This
- * will ensure that even if the message "#define name" is not
- * completely descriptive, the message reason code is.
- *
- * b31 = direction. 0=Host-to-Target; 1=Target-to-Host;
- * b30-16 = reserved. should be zero
- * b15-0 = message reason code.
- *
- * Note that typically a request will be initiated by the target side, and
- * that the host will then respond with either an acknowledgement or some
- * data. In either case the same reason code will be used, but the direction
- * bit will be reveresed.
