+Notes for the branch "gdb-csl-available-20060303-branch"
+--------------------------------------------------------
+
+This branch implements a new mechanism which allows GDB to ask a target
+"what features do you have?" GDB can then interpret the response and
+dynamically present those features to the user. Some features require
+corresponding support in GDB, and must be specially recognized by the target
+architecture. Others do not require additional GDB support, e.g. additional
+registers (the only type of feature implemented so far).
+
+The branch does not have a ChangeLog relative to mainline; one will be written
+later. So far, only the ARM target has any support for available features.
+
+The most interesting portion of this document is the TODO list; the rest may
+get somewhat out of date.
+
+Control flow in GDB
+-------------------
+
+After connecting to the target, we check the new architecture-provided setting
+gdbarch_available_features_support. If it is set, we query the target
+for its available features, interpret the response, and switch to a new
+gdbarch, derived from the current one, with these features recorded.
+
+In order for the derivation process to work, the architecture's gdbarch_init
+must correctly support filling in defaults based on the last used architecture.
+If it does not, for example, cache something read from the ELF binary in
+gdbarch_tdep, the architecture is likely to get out of sync with the
+debuggee.
+
+During debugging, GDB can query information from the current set of
+features. This is currently done in architecture-specific hooks, but may be
+done in common code in the future.
+
+Writing a feature description
+-----------------------------
+
+Feature descriptions are written in XML. The current DTD is in
+gdb/features/gdb-target.dtd. There are some limits beyond those
+expressed in the DTD - many of these limits are not yet documented
+and not yet relevant until additional GDB support has been implemented.
+See the TODO.
+
+Here's a simple sample description:
+
+<?xml version="1.0"?>
+<!DOCTYPE target SYSTEM "gdb-target.dtd">
+<target>
+ <feature name="bar">
+ <reg name="s0" bitsize="32"/>
+ <reg name="s1" bitsize="32" type="float"/>
+ </feature>
+
+ <feature-set>
+ <feature-ref name="bar" base-regnum="1"/>
+ </feature-set>
+</target>
+
+This describes a simple target feature set which only contains two registers,
+named s0 (32-bit, integer) and s1 (32-bit, floating point).
+
+You can spread a description over multiple files by using the standardized
+XInclude mechanism - but only whole-file XInclude is supported. The
+xpointer attribute should not be used, and the href attribute should be,
+using a bare basename. GDB will query the target for the file, if it has
+not already seen it.
+
+You can validate the description using any XML validator which supports XInclude.
+For instance, with "xmllint" (shipped as part of the GNOME libxml2 package):
+
+ xmllint --xinclude --postvalid my-target.xml
+
+Post validation is usually appropriate when using XInclude; the DTD describes
+the document after XInclude processing.
+
+GDB fetches CHECKSUMS initially. Files with a listed checksum may be
+fetched from a cache instead of from the target (currently only RAM caching
+is implemented). Next, GDB fetches "target.xml", and then any files
+included using XInclude. Files not listed in CHECKSUMS will not be fetched
+from the cache - they may be e.g. generated on the fly. The target
+description is fetched on connect, and again after application restart in
+case it has changed (TODO: is this wasteful, should it be fetched only
+once? This only matters for target extended-remote, so it isn't a big
+deal right now.)
+
+By default, feature names must be unique within the document (XML "ID"
+constraint), but not globally unique. However, GDB must recognize some
+features explicitly to enable additional support for them. It uses the
+feature name to detect their presence. These features should have
+unambiguous, globally unique names. If the feature is described in the GDB
+manual, use the name listed there. If not, and you are adding code to a
+local version of GDB to recognize the feature by name, please use a name
+which includes your organization. For instance, "org.gnu.gdb.arm.core", or
+"com.codesourcery.foovendor.coproc". This method prevents conflicts with
+other names chosen by other groups.
+
+The target description should specify every register provided by the
+target, including the GDB standard ones.
+
+
+TODO items and unsettled (or unasked) questions
+-----------------------------------------------
+
+When finished this documentation needs to move into the user and internals
+manual.
+
+The "ro" and "save-restore" tags may not express enough information about
+how to treat system registers. Richard Earnshaw suggested a more detailed
+categorization; I need to consider it; I think it's a good idea at first
+glance.
+
+Reading and writing registers using the 'p' and 'P' packets is very
+inefficient; a target mechanism and remote protocol packets for multiple
+register batching would probably help a lot. Note, the branch now does a
+simple subset of this assuming a reasonable 'g' packet.
+
+For ARM VFP, there are two views of some registers: s0 / s1 are single precision
+registers overlayed in storage with d0, a double precision register. Many
+other targets do the same thing. Should we express this to GDB, or just
+allow it to read them both from the target (somewhat wasteful)? GDB already
+assumes that modifying one register may modify another unpredictably, so
+writing is OK - the only problem is a waste of bandwidth.
+
+The DTD allows for description fields, including multi-lingual ones, but
+there is no GDB support for descriptions. It would be good to present
+them to the user.
+
+Should we convey the information read from the target (after e.g. XInclude
+processing) to MI front ends, or are the changes to the register cache
+sufficient? For instance, Eclipse would probably be happy to display most
+of this data (especially descriptions). I think there should be one MI
+command to fetch the DTD used, and another to fetch the description used.
+XInclude processing has been moved into a separate phase to facilitate this.
+Because other external entities are not supported, these two are guaranteed
+to convey the entire description.
+
+The current DTD and GDB support does not allow for nested features. This
+is probably useful. I think this will be a must-have in the long term.
+
+GDB needs additional error checking for its assumptions of unique names.
+For instance, there may be multiple registers with the same name in
+GDB's feature database, but they had better not be instantiated in
+the same feature set.
+
+Should known features be compiled in to GDB, or loaded from the filesystem?
+The most essential features should probably be compiled in, so that the GDB
+binary is useful standalone. The DTD is already compiled in, but there's no
+support for a target to supply default features by XML instead of hand
+coding.
+
+GDB should support reading features and feature sets from disk instead of
+from the target.
+
+GDB should support caching features read from the target in a user-specified
+directory.
+
+Should GDB warn about unrecognized features which require additional GDB
+support, or silently ignore them? Currently there is no way to detect
+this. It's not a big deal.
+
+Since the name field of features may be hierarchical, and the description is
+free-form (more like "help text"), there should probably be a "short
+description" field - a user label without the uniqueness constraint.
+
+Another suggested type of feature is a memory map - which areas of memory
+the debugger may read from / write to.
+
+Targets could use XML to supply their default feature set. It's nice in that
+it moves a bit of code from the tdep files out into a description file; but
+less nice in that it might lose flexibility that we need; the target might
+have to run-time generate the XML. Currently there are no plans to require
+this, but it may turn out to be a simplifying assumption later.
+
+Register group handling right now is somewhat simplistic; only
+group="general", group="float", group="vector", and no explicit group
+setting (use type to categorize) are supported. We could extend this, or
+we could limit it to those and provide an alternate hierarchy based on
+the containing features.
+
+Eventually supporting multiple instances of a feature is desirable. This
+requires some instance-name on the feature reference, and using that to
+prefix the registers for that feature. Maybe treat the registers as a large
+struct. This would be sort of useful anyway, to avoid clobbering
+the convenience variable namespace. Maybe only "core" registers should
+be in the default namespace? Maybe key that off the description, empty
+or missing instance-name -> default namespace?
+
+In the mean time, GDB should check for duplicated register names, and
+warn that it can not support them.
+
+Should hardware MMIO registers be treated as registers, or as memory, or
+using new read/write packets that can guarantee appropriate I/O width?
+If as registers, we need to be careful with ones where reading them
+triggers an action (e.g. resetting some state).
+
+A nice-to-have item would be a basic architecture identifier:
+ (gdb) target remote board:2345
+ warning: This GDB does not support the "arm" architecture.
+
+Should the current extended-remote be changed from a client-requested
+property ("!" packet) to a target-announced property? Some stubs
+should always be used in extended mode, some don't support it. Some
+get by with either, but usually, not very well.

+@node Self-Describing Targets
+@appendix Self-Describing Targets
+
+One of the challenges of using @value{GDBN} to debug embedded systems
+is that there are so many minor variants of each processor
+architecture in use. It is common practice for vendors to start with
+a standard processor core --- ARM, PowerPC, or MIPS, for example ---
+and then make changes to adapt it to a particular market niche. Some
+architectures have hundreds of variants, available from dozens of
+vendors. This leads to a number of problems:
+
+@itemize @bullet
+@item
+With so many different customized processors, it is difficult for
+the @value{GDBN} maintainers to keep up with the changes.
+@item
+Since individual variants may have short lifetimes or limited
+audiences, it may not be worthwhile to carry information about every
+variant in the @value{GDBN} source tree.
+@item
+When @value{GDBN} does support the architecture of the embedded system
+at hand, the task of finding the correct architecture name to give the
+@command{set architecture} command can be error-prone.
+@end itemize
+
+To address these problems, the @value{GDBN} remote protocol allows a
+target system to not only identify itself to @value{GDBN}, but to
+actually describe its own features. This lets @value{GDBN} support
+processor variants it has never seen before --- to the extent that the
+descriptions are accurate, and that @value{GDBN} understands them.
+
+@menu
+* Retrieving Self-Descriptions:: How descriptions are fetched from a target.
+* Self-Description Format:: The contents of a self-description.
+@end menu
+
+@node Retrieving Self-Descriptions
+@section Retrieving Self-Descriptions
+
+A target can split its self-description into one or more pieces,
+called @dfn{annexes}. @value{GDBN} retrieves each annex via the
+remote protocol using @code{qPart} requests (@pxref{the qPart
+request}) of the form:
+
+@example
+qPart:features:read:@var{annex}:@var{offset},@var{length}
+@end example
+
+@noindent
+where @var{annex} is the name of the annex, and the @var{offset} and
+@var{length} parameters are the offset into the description and the
+number of bytes to transfer, as for other @code{qPart} requests.
+
+To retrieve a target's self-description, @value{GDBN} first fetches
+the annex named @samp{target.xml}. This is an XML document, of the
+form described in @ref{Self-Description Format}. Just as C header
+files can refer to other header files using @code{#include}, target
+description annexes can use @uref{http://www.w3.org/TR/xinclude/, XML
+Inclusions} to incorporate other annexes. Starting with
+@samp{target.xml}, @value{GDBN} makes further @code{qPart} requests as
+needed to resolve all the inclusions and assemble the complete
+description.
+
+To reduce protocol overhead, a target may supply a special annex named
+@samp{CHECKSUMS} that provides 160-bit SHA-1@footnote{The SHA-1 hash
+function is defined in
+@uref{http://www.itl.nist.gov/fipspubs/fip180-1.htm, Federal
+Information Processing Standards Publication 180-1}. The GNU
+coreutils contain a Free implementation of SHA-1.} checksum values
+for the annexes it has available. The @samp{CHECKSUMS} annex contains
+a series of newline-terminated lines, each of which contains a
+40-digit hexidecimal checksum, two spaces, and the name of an annex
+with the given checksum. Here is an example @samp{CHECKSUMS} annex:
+
+@example
+68c94ffc34f8ad2d7bfae3f5a6b996409211c1b1 target.xml
+0e8e850b0580fbaaa0872326cb1b8ad6adda9b0d mmu.xml
+00f22e5f971ccec05c2acce98caf8cff4343c8cf fpu.xml
+@end example
+
+@value{GDBN} uses these checksums to avoid retrieving a given annex
+more than once. When @value{GDBN} retrieves an annex, it caches its
+contents locally. Then, each time @value{GDBN} thinks the target
+architecture may have changed (say, after making a new remote protocol
+connection, or after starting a new child process using the extended
+remote protocol), it retrieves the @samp{CHECKSUMS} annex afresh. If
+the checksums show that a particular annex's contents are the same on
+the target and in @value{GDBN}'s cache, @value{GDBN} avoids fetching
+it again. If none of the annexes have changed, @value{GDBN} needs
+only retrieve the @samp{CHECKSUMS} annex.
+
+@samp{CHECKSUMS} need not provide a checksum for every annex
+available; if a given annex is not mentioned, @value{GDBN} will try to
+retrieve it each time it thinks the target architecture may have
+changed. The target need not provide any @samp{CHECKSUMS} annex at
+all; this is equivalent to an empty @samp{CHECKSUMS} annex.
+
+
+@node Self-Description Format
+@section Self-Description Format
+
+A target description annex is an @uref{http://www.w3.org/XML/, XML}
+document which complies with the Document Type Definition provided in
+the @value{GDBN} sources in @file{gdb/features/gdb-target.dtd}. This
+means you can use generally available tools like @command{xmllint} to
+check that your feature descriptions are well-formed and valid.
+However, to help people unfamiliar with XML write descriptions for
+their targets, we also describe the grammar here.
+
+At the moment, target descriptions can only describe register sets, to
+be accessed via the remote protocol @code{g}, @code{G}, @code{p} and
+@code{P} requests. We hope to extend the format to include other
+kinds of information, like memory maps.
+
+Here is a simple sample target description:
+
+@example
+<?xml version="1.0"?>
+<!DOCTYPE target SYSTEM "gdb-target.dtd">
+<target>
+ <feature name="bar">
+ <reg name="s0" bitsize="32"/>
+ <reg name="s1" bitsize="32" type="float"/>
+ </feature>
+
+ <feature-set>
+ <feature-ref name="bar" base-regnum="1"/>
+ </feature-set>
+</target>
+@end example
+
+@noindent
+This describes a simple target feature set which only contains two
+registers, named @code{s0} (a 32-bit integer register) and @code{s1}
+(a 32-bit floating point register).
+
+A target description has the overall form:
+
+@example
+<?xml version="1.0"?>
+<!DOCTYPE target SYSTEM "gdb-target.dtd">
+<target>
+ @var{feature}@dots{}
+ @var{feature-set}
+</target>
+@end example
+
+@noindent
+The description is generally insensitive to whitespace and line
+breaks, under the usual common-sense rules. The ellipsis
+(@samp{@dots{}}) after @var{feature} indicates that @var{feature} may
+appear zero or more times.
+
+Each @var{feature} names and describes a single feature of the target;
+at the moment, features can only describe register sets. The
+@var{feature-set} cites particular features by name, pulling together
+a complete description of the target. A @var{feature} has the form:
+
+@example
+<feature name="@var{name}">
+ @var{reg}@dots{}
+</feature>
+@end example
+
+@noindent
+This defines a feature named @var{name}; each feature's name must be
+unique across the description.
+
+Each @var{reg} has the form:
+
+@example
+<reg name="@var{name}"
+ bitsize="@var{size}"
+ @r{[}regnum="@var{num}"@r{]}
+ @r{[}save-restore="@var{save-restore}"@r{]}
+ @r{[}type="@var{type}"@r{]}
+ @r{[}group="@var{group}"@r{]}/>
+@end example
+
+@noindent
+Items in @r{[}brackets@r{]} are optional. The components are as follows:
+
+@table @var
+
+@item name
+The register's name; it must be unique within the target description.
+
+@item bitsize
+The register's size, in bits.
+
+@item regnum
+The register's number. If omitted, a register's number is one greater
+than that of the previous register; the first register's number
+defaults to zero. But also see the @code{feature-ref} element's
+@code{base-regnum} attribute, below---these register numbers are relative
+to the @code{base-regnum}.
+
+@item save-restore
+Whether the register should be preserved across inferior function
+calls; this must be either @code{yes} or @code{no}. The default is
+@code{yes}.
+
+@item type
+The type of the register. At the moment, @var{type} must be either
+@code{int} or @code{float}. The default is @code{int}.
+
+@item group
+The register group to which this register belongs. At the moment,
+@var{group} must be either @code{general}, @code{float}, or
+@code{vector}. If no @var{group} is specified, @value{GDBN} will
+select a register group based on the register's type.
+
+@end table
+
+A @var{feature-set} binds together a set of features to describe
+a complete target. There can be only one @var{feature-set} in a
+target. Each @var{feature-set} has the form:
+
+@example
+<feature-set>
+ @var{feature-ref}@dots{}
+</feature-set>
+@end example
+
+@noindent
+where each @var{feature-ref} has the form:
+
+@example
+<feature-ref name="@var{name}" @r{[}base-regnum="@var{n}"@r{]}/>
+@end example
+
+@noindent
+This means that the target includes the feature named @var{name}. If
+the @code{base-regnum} is present, that means that registers in the
+given feature are numbered starting with @var{n}, until overridden by
+an explicit register number.
+
+It can sometimes be valuable to split a target description up into
+several different annexes, either for organizational purposes, or to
+allow @value{GDBN} to cache portions of the description that change
+rarely. To make this possible, you can replace any feature
+description with an inclusion directive of the form:
+
+@example
+<xi:include href="@var{annex}"/>
+@end example
+
+@noindent
+When @value{GDBN} encounters an element of this form, it will retrieve
+the annex named @var{annex} (or use its cached copy), and replace the
+inclusion directive with the contents of that annex.
