table. If an archive lacks the table, another form of @command{ar} called
@command{ranlib} can be used to add just the table.
+@cindex thin archives
+@sc{gnu} @command{ar} can optionally create a @emph{thin} archive,
+which contains a symbol index and references to the original copies
+of the member files of the archive. This is useful for building
+libraries for use within a local build tree, where the relocatable
+objects are expected to remain available, and copying the contents of
+each object would only waste time and space.
+
+An archive can either be @emph{thin} or it can be normal. It cannot
+be both at the same time. Once an archive is created its format
+cannot be changed without first deleting it and then creating a new
+archive in its place.
+
+Thin archives are also @emph{flattened}, so that adding one thin
+archive to another thin archive does not nest it, as would happen with
+a normal archive. Instead the elements of the first archive are added
+individually to the second archive.
+
+The paths to the elements of the archive are stored relative to the
+archive itself. For security reasons absolute paths and paths with a
+@code{/../} component are not allowed.

@cindex @command{ar} compatibility
@sc{gnu} @command{ar} is designed to be compatible with two different
@smallexample
@c man begin SYNOPSIS ar
-ar [@option{-X32_64}] [@option{-}]@var{p}[@var{mod} [@var{relpos}] [@var{count}]] @var{archive} [@var{member}@dots{}]
+ar [@option{-X32_64}] [@option{-}]@var{p}[@var{mod}] [@option{--plugin} @var{name}] [@option{--target} @var{bfdname}] [@var{relpos}] [@var{count}] @var{archive} [@var{member}@dots{}]
@c man end
@end smallexample
The modifier @samp{v} makes @command{ar} list each file as it is appended.
-Since the point of this operation is speed, the archive's symbol table
-index is not updated, even if it already existed; you can use @samp{ar s} or
-@command{ranlib} explicitly to update the symbol table index.
+Since the point of this operation is speed, implementations of
+@command{ar} have the option of not updating the archive's symbol
+table if one exists. Too many different systems however assume that
+symbol tables are always up-to-date, so @sc{gnu} @command{ar} will
+rebuild the table even with a quick append.
-However, too many different systems assume quick append rebuilds the
-index, so @sc{gnu} @command{ar} implements @samp{q} as a synonym for @samp{r}.
+Note - @sc{gnu} @command{ar} treats the command @samp{qs} as a
+synonym for @samp{r} - replacing already existing files in the
+archive and appending new ones at the end.
@item r
@cindex replacement in archive
@samp{r} to indicate whether the file was appended (no old member
deleted) or replaced.
+@item s
+@cindex ranlib
+Add an index to the archive, or update it if it already exists. Note
+this command is an exception to the rule that there can only be one
+command letter, as it is possible to use it as either a command or a
+modifier. In either case it does the same thing.
+
@item t
@cindex contents of archive
Display a @emph{table} listing the contents of @var{archive}, or those
If you do not specify a @var{member}, all files in the archive
are extracted.
+Files cannot be extracted from a thin archive.
+
+@item --help
+Displays the list of command line options supported by @command{ar}
+and then exits.
+
+@item --version
+Displays the version information of @command{ar} and then exits.
+
@end table
A number of modifiers (@var{mod}) may immediately follow the @var{p}
issued unless you specify in advance that you expect to create it, by
using this modifier.
+@item D
+@cindex deterministic archives
+@kindex --enable-deterministic-archives
+Operate in @emph{deterministic} mode. When adding files and the archive
+index use zero for UIDs, GIDs, timestamps, and use consistent file modes
+for all files. When this option is used, if @command{ar} is used with
+identical options and identical input files, multiple runs will create
+identical output files regardless of the input files' owners, groups,
+file modes, or modification times.
+
+If @file{binutils} was configured with
+@option{--enable-deterministic-archives}, then this mode is on by default.
+It can be disabled with the @samp{U} modifier, below.
+
@item f
Truncate names in the archive. @sc{gnu} @command{ar} will normally permit file
names of any length. This will cause it to create archives which are
@samp{S} modifier on the last execution of @samp{ar}, or you must run
@samp{ranlib} on the archive.
+@item T
+@cindex creating thin archive
+Make the specified @var{archive} a @emph{thin} archive. If it already
+exists and is a regular archive, the existing members must be present
+in the same directory as @var{archive}.
+
@item u
@cindex updating an archive
Normally, @samp{ar r}@dots{} inserts all files
not allowed, since checking the timestamps would lose any speed
advantage from the operation @samp{q}.
+@item U
+@cindex deterministic archives
+@kindex --enable-deterministic-archives
+Do @emph{not} operate in @emph{deterministic} mode. This is the inverse
+of the @samp{D} modifier, above: added files and the archive index will
+get their actual UID, GID, timestamp, and file mode values.
+
+This is the default unless @file{binutils} was configured with
+@option{--enable-deterministic-archives}.
+
@item v
This modifier requests the @emph{verbose} version of an operation. Many
operations display additional information, such as filenames processed,
@samp{-X} options; in particular, it does not support @option{-X32}
which is the default for AIX @command{ar}.
+The optional command line switch @option{--plugin} @var{name} causes
+@command{ar} to load the plugin called @var{name} which adds support
+for more file formats. This option is only available if the toolchain
+has been built with plugin support enabled.
+
+The optional command line switch @option{--target} @var{bfdname}
+specifies that the archive members are in an object code format
+different from your system's default format. See
+@xref{Target Selection}, for more information.

+
+The default interleave breadth is 4, so with @option{--byte} set to 0,

basis.
+@item --strip-dwo
+Remove the contents of all DWARF .dwo sections, leaving the
+remaining debugging sections and all symbols intact.
+This option is intended for use by the compiler as part of
+the @option{-gsplit-dwarf} option, which splits debug information
+between the .o file and a separate .dwo file. The compiler
+generates all debug information in the same file, then uses
+the @option{--extract-dwo} option to copy the .dwo sections to
+the .dwo file, then the @option{--strip-dwo} option to remove
+those sections from the original .o file.

+Use @var{value} as the base address of your program or dll. This is
+the lowest memory location that will be used when your program or dll
+is loaded. To reduce the need to relocate and improve performance of
+your dlls, each should have a unique base address and not overlap any
+other dlls. The default is 0x400000 for executables, and 0x10000000
+for dlls.

-For each @var{file} given, @sc{gnu} @command{strings} prints the printable
-character sequences that are at least 4 characters long (or the number
-given with the options below) and are followed by an unprintable
-character. By default, it only prints the strings from the initialized
-and loaded sections of object files; for other types of files, it prints
-the strings from the whole file.
+For each @var{file} given, @sc{gnu} @command{strings} prints the
+printable character sequences that are at least 4 characters long (or
+the number given with the options below) and are followed by an
+unprintable character.
+
+Depending upon how the strings program was configured it will default
+to either displaying all the printable sequences that it can find in
+each file, or only those sequences that are in loadable, initialized
+data sections. If the file type in unrecognizable, or if strings is
+reading from stdin then it will always display all of the printable
+sequences that it can find.
-@command{strings} is mainly useful for determining the contents of non-text
-files.
+For backwards compatibility any file that occurs after a command line
+option of just @option{-} will also be scanned in full, regardless of
+the presence of any @option{-d} option.

-Do not scan only the initialized and loaded sections of object files;
-scan the whole files.
+Scan the whole file, regardless of what sections it contains or
+whether those sections are loaded or initialized. Normally this is
+the default behaviour, but strings can be configured so that the

+specified.

+@item -d
+@itemx --data
+Only print strings from initialized, loaded data sections in the

+also exposes the strings program to any security flaws that may be
+present in the BFD library used to scan and load sections. Strings
+can be configured so that this option is the default behaviour. In
