     is a rough summary of which licenses apply to which parts of this
     package (but check the individual files to be sure!):
 
-      - liblzma is in the public domain.
+      - liblzma is under the BSD Zero Clause License (0BSD).
 
-      - xz, xzdec, and lzmadec command line tools are in the public
-        domain unless GNU getopt_long had to be compiled and linked
-        in from the lib directory. The getopt_long code is under
-        GNU LGPLv2.1+.
+      - The command line tools xz, xzdec, lzmadec, and lzmainfo are
+        under 0BSD except that, on systems that don't have a usable
+        getopt_long, GNU getopt_long is compiled and linked in from the
+        'lib' directory. The getopt_long code is under GNU LGPLv2.1+.
 
       - The scripts to grep, diff, and view compressed files have been
-        adapted from gzip. These scripts and their documentation are
-        under GNU GPLv2+.
-
-      - All the documentation in the doc directory and most of the
-        XZ Utils specific documentation files in other directories
-        are in the public domain.
+        adapted from GNU gzip. These scripts (xzgrep, xzdiff, xzless,
+        and xzmore) are under GNU GPLv2+. The man pages of the scripts
+        are under 0BSD; they aren't based on the man pages of GNU gzip.
+
+      - Most of the XZ Utils specific documentation that is in
+        plain text files (like README, INSTALL, PACKAGERS, NEWS,
+        and ChangeLog) are under 0BSD unless stated otherwise in
+        the file itself. The files xz-file-format.txt and
+        lzma-file-format.xt are in the public domain but may
+        be distributed under the terms of 0BSD too.
+
+      - Doxygen-generated HTML version of the liblzma API documentation:
+        While Doxygen is under the GNU GPLv2, the license information
+        in Doxygen includes the following exception:
+
+            Documents produced by doxygen are derivative works
+            derived from the input used in their production;
+            they are not affected by this license.
 
         Note: The JavaScript files (under the MIT license) have
-        been removed from the Doxygen-generated HTML version of the
-        liblzma API documentation. Doxygen itself is under the GNU GPL
-        but the remaining files generated by Doxygen are not affected
-        by the licenses used in Doxygen because Doxygen licensing has
-        the following exception:
+        been removed from the Doxygen output.
 
-            "Documents produced by doxygen are derivative works
-            derived from the input used in their production;
-            they are not affected by this license."
+      - The XZ logo (xz-logo.png) included in the Doxygen-generated
+        documentation is under the Creative Commons BY-SA 4.0 license.
 
-      - Translated messages are in the public domain.
+      - Translated messages and man pages are under 0BSD except that
+        some old translations are in the public domain.
 
-      - The build system contains public domain files, and files that
-        are under GNU GPLv2+ or GNU GPLv3+. None of these files end up
-        in the binaries being built.
+      - Test files and test code in the 'tests' directory, and
+        debugging utilities in the 'debug' directory are under
+        the BSD Zero Clause License (0BSD).
 
-      - Test files and test code in the tests directory, and debugging
-        utilities in the debug directory are in the public domain.
+      - The GNU Autotools based build system contains files that are
+        under GNU GPLv2+, GNU GPLv3+, and a few permissive licenses.
+        These files don't affect the licensing of the binaries being
+        built.
 
-      - The extra directory may contain public domain files, and files
-        that are under various free software licenses.
+      - The extra directory contain files that are under various
+        free software licenses.
 
-    You can do whatever you want with the files that have been put into
-    the public domain. If you find public domain legally problematic,
-    take the previous sentence as a license grant. If you still find
-    the lack of copyright legally problematic, you have too many
-    lawyers.
+    For the files under the BSD Zero Clause License (0BSD), if
+    a copyright notice is needed, the following is sufficient:
 
-    As usual, this software is provided "as is", without any warranty.
+        Copyright (C) The XZ Utils authors and contributors
 
-    If you copy significant amounts of public domain code from XZ Utils
+    If you copy significant amounts of 0BSD-licensed code from XZ Utils
     into your project, acknowledging this somewhere in your software is
     polite (especially if it is proprietary, non-free software), but
-    naturally it is not legally required. Here is an example of a good
-    notice to put into "about box" or into documentation:
+    it is not legally required by the license terms. Here is an example

       - COPYING.GPLv2: GNU General Public License version 2
       - COPYING.GPLv3: GNU General Public License version 3
-
-    Note that the toolchain (compiler, linker etc.) may add some code
-    pieces that are copyrighted. Thus, it is possible that e.g. liblzma
-    binary wouldn't actually be in the public domain in its entirety
-    even though it contains no copyrighted code from the XZ Utils source
-    package.
-
-    If you have questions, don't hesitate to ask the author(s) for more
-    information.

+
+    A note about old XZ Utils releases:
+
+        XZ Utils releases 5.4.6 and older and 5.5.1alpha have a
+        significant amount of code put into the public domain and
+        that obviously remains so. The switch from public domain to
+        0BSD for newer releases was made in Febrary 2024 because
+        public domain has (real or perceived) legal ambiguities in
+        some jurisdictions.
+
+        There is very little *practical* difference between public
+        domain and 0BSD. The main difference likely is that one
+        shouldn't claim that 0BSD-licensed code is in the public
+        domain; 0BSD-licensed code is copyrighted but available under
+        an extremely permissive license. Neither 0BSD nor public domain
+        require retaining or reproducing author, copyright holder, or
+        license notices when distributing the software. (Compare to,
+        for example, BSD 2-Clause "Simplified" License which does have
+        such requirements.)
+
+    If you have questions, don't hesitate to ask for more information.
+    The contact information is in the README file.

+Using Creative Commons Public Licenses
+
+Creative Commons public licenses provide a standard set of terms and
+conditions that creators and other rights holders may use to share
+original works of authorship and other material subject to copyright
+and certain other rights specified in the public license below. The
+following considerations are for informational purposes only, are not
+exhaustive, and do not form part of our licenses.
+
+     Considerations for licensors: Our public licenses are
+     intended for use by those authorized to give the public
+     permission to use material in ways otherwise restricted by
+     copyright and certain other rights. Our licenses are
+     irrevocable. Licensors should read and understand the terms
+     and conditions of the license they choose before applying it.
+     Licensors should also secure all rights necessary before
+     applying our licenses so that the public can reuse the
+     material as expected. Licensors should clearly mark any
+     material not subject to the license. This includes other CC-
+     licensed material, or material used under an exception or
+     limitation to copyright. More considerations for licensors:

+
+     Considerations for the public: By using one of our public
+     licenses, a licensor grants the public permission to use the
+     licensed material under specified terms and conditions. If
+     the licensor's permission is not necessary for any reason--for
+     example, because of any applicable exception or limitation to
+     copyright--then that use is not regulated by the license. Our
+     licenses grant only permissions under copyright and certain
+     other rights that a licensor has authority to grant. Use of
+     the licensed material may still be restricted for other
+     reasons, including because others have copyright or other
+     rights in the material. A licensor may make special requests,
+     such as asking that all changes be marked or described.
+     Although not required by our licenses, you are encouraged to
+     respect those requests where reasonable. More considerations

+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. Additional offer from the Licensor -- Adapted Material.
+               Every recipient of Adapted Material from You
+               automatically receives an offer from the Licensor to
+               exercise the Licensed Rights in the Adapted Material
+               under the conditions of the Adapter's License You apply.
+
+            c. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+

+          rights granted under the Adapter's License You apply.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material,
+     including for purposes of Section 3(b); and
+
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not

+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR

+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

+
+    Build: Fix ARM64 CRC32 instruction feature test.
+    
+    Old versions of Clang reported the unsupported function attribute and
+    __crc32d() function as warnings instead of errors, so the feature test
+    passed when it shouldn't have, causing a compile error at build time.
+    -Werror was added to this feature test to fix this. The change is not
+    needed for CMake because check_c_source_compiles() also performs
+    linking and the error is caught then.
+    
+    Thanks to Sebastian Andrzej Siewior for reporting this.

+
+    xz: Landlock: Fix error message if input file is a directory.
+    
+    If xz is given a directory, it should look like this:
+    
+        $ xz /usr/bin
+        xz: /usr/bin: Is a directory, skipping
+    
+    The Landlock rules didn't allow opening directories for reading:
+    
+        $ xz /usr/bin
+        xz: /usr/bin: Permission denied
+    
+    The simplest fix was to allow opening directories for reading.
+    While it's a bit silly to allow it solely for the error message,
+    it shouldn't make the sandbox significantly weaker.
+    
+    The single-file use case (like when called from GNU tar) is
+    still as strict as possible: all Landlock restrictions are
+    enabled before (de)compression starts.

+
+    Windows: Update windows/build.bash.
+    
+    Support for the old MinGW was dropped. Only MinGW-w64 with GCC
+    is supported now.
+    
+    The script now supports also cross-compilation from GNU/Linux
+    (tests are not run). MSYS2 and also the old MSYS 1.0.11 work
+    for building on Windows. The i686 and x86_64 toolchains must
+    be in PATH to build both 32-bit and 64-bit versions.
+    
+    Parallel builds are done if "nproc" from GNU coreutils is available.
+    
+    MinGW-w64 runtime copyright information file was renamed from
+    COPYING-Windows.txt to COPYING.MinGW-w64-runtime.txt which
+    is the filename used by MinGW-w64 itself. Its existence
+    is now mandatory, it's checked at the beginning of the script.
+    
+    The file TODO is no longer copied to the package.

+
+    CMake: Don't assume that -fvisibility=hidden is supported outside Windows.
+    
+    The original code was good enough for supporting GNU/Linux
+    and a few others but it wasn't very portable.
+    
+    CMake doesn't support Solaris Studio's -xldscope=hidden.
+    If it ever does, things should still work with this commit
+    as Solaris Studio supports not only its own __global but also
+    the GNU C __attribute__((visibility("default"))). Support for the
+    attribute was added in 2007 to Sun Studio 12 compiler version 5.9.

+
+    CMake: Use -O2 instead of -O3 in CMAKE_BUILD_TYPE=Release.
+    
+    -O3 doesn't seem useful for speed but it makes the code bigger.
+    CMake makes is difficult for users to simply override the
+    optimization level: CFLAGS / CMAKE_C_FLAGS aren't helpful because
+    they go before CMAKE_C_FLAGS_RELEASE. Of course, users can override
+    CMAKE_C_FLAGS_RELEASE directly but then they have to remember to
+    add also -DNDEBUG to disable assertions.
+    
+    This commit changes -O3 to -O2 in CMAKE_C_FLAGS_RELEASE if and only if
+    CMAKE_C_FLAGS_RELEASE cache variable doesn't already exist. So if
+    a custom value is passed on the command line (or reconfiguring an
+    already-configured build), the cache variable won't be modified.

+
+    CMake: Simplify symlink creation and install translated man pages.
+    
+    It helps that cmake_install.cmake doesn't parallelize installation
+    so symlinks can be created so that the target is always known to
+    exist (a requirement on Windows in some cases).
+    
+    This bumps the minimum CMake version from 3.13 to 3.14 to use
+    file(CREATE_LINK ...). It could be made to work on 3.13 by
+    calling "cmake -E create_symlink" but it's uglier code and
+    slower in "make install". 3.14 should be a reasonable version
+    to require nowadays, especially since the Autotools build
+    is still the primary build system for most OSes.

+
+    CMake: Add support for building and installing xz with translations.
+    
+    If gettext tools are available, the .po files listed in po/LINGUAS
+    are converted using msgfmt. This allows building with translations
+    directly from xz.git without Autotools.
+    
+    If gettext tools aren't available, the Autotools-created .gmo files
+    in the "po" directory will be used. This allows CMake-based build
+    to use translations from Autotools-generated tarball.
+    
+    If translation support is found (Intl_FOUND) but both the
+    gettext tools and the pre-generated .gmo files are missing,
+    then "make" will fail.

+    xz: Use stricter pledge(2) and Landlock sandbox.
+    
+    This makes these sandboxing methods stricter when no files are
+    created or deleted. That is, it's a middle ground between the
+    initial sandbox and the strictest single-file-to-stdout sandbox:
+    this allows opening files for reading but output has to go to stdout.

+
+    xz: Support Landlock ABI version 4.
+    
+    Linux 6.7 added support for ABI version 4 which restricts
+    TCP connections which xz won't need and thus those can be
+    forbidden now. Since the ABI version is handled at runtime,
+    supporting version 4 won't cause any compatibility issues.
+    
+    Note that new enough kernel headers are required to get
+    version 4 support enabled at build time.

+
+    xz: Move sandboxing code to sandbox.c and improve Landlock sandbox.
+    
+    Landlock is now always used just like pledge(2) is: first in more
+    permissive mode and later (under certain common conditions) in
+    a strict mode that doesn't allow opening more files.
+    
+    I put pledge(2) first in sandbox.c because it's the simplest API
+    to use and still somewhat fine-grained for basic applications.
+    So it's the simplest thing to understand for anyone reading sandbox.c.

+
+    liblzma: Optimize LZ decoder slightly.
+    
+    Now extra buffer space is reserved so that repeating bytes for
+    any single match will never need to copy from two places (both
+    the beginning and the end of the buffer). This simplifies
+    dict_repeat() and helps a little with speed.
+    
+    This seems to reduce .lzma decompression time about 2 %, so
+    with .xz and CRC it could be slightly less. The small things
+    add up still.

+
+    liblzma: Creates Non-resumable and Resumable modes for lzma_decoder.
+    
+    The new decoder resumes the first decoder loop in the Resumable mode.
+    Then, the code executes in Non-resumable mode until it detects that it
+    cannot guarantee to have enough input/output to decode another symbol.
+    
+    The Resumable mode is how the decoder has always worked. Before decoding
+    every input bit, it checks if there is enough space and will save its
+    location to be resumed later. When the decoder has more input/output,
+    it jumps back to the correct sequence in the Resumable mode code.
+    
+    When the input/output buffers are large, the Resumable mode is much
+    slower than the Non-resumable because it has more branches and is harder
+    for the compiler to optimize since it is in a large switch block.
+    
+    Early benchmarking shows significant time improvement (8-10% on gcc and
+    clang x86) by using the Non-resumable code as much as possible.

+
+    liblzma: Creates separate "safe" range decoder mode.
+    
+    The new "safe" range decoder mode is the same as old range decoder, but
+    now the default behavior of the range decoder will not check if there is
+    enough input or output to complete the operation. When the buffers are
+    close to fully consumed, the "safe" operations must be used instead. This
+    will improve speed because it will reduce the number of branches needed
+    for most of the range decoder operations.

+
+    xzdiff, xzgrep, and xzmore: Rewrite the man pages.
+    
+    The main reason is a kind of silly one:
+    
+    xz-man.pot contains strings from all man pages in XZ Utils.
+    The man pages of xzdiff, xzgrep, and xzmore were under GPLv2
+    and the rest under 0BSD. Thus xz-man.pot contained strings
+    under two licences. po4a creates the translated man pages
+    from the combined 0BSD+GPLv2 xz-man.pot.
+    
+    I haven't liked this mixing in xz-man.pot but the
+    Translation Project requires that all man pages must be
+    in the same .pot file. So a separate xz-man-gpl.pot
+    wasn't an option.
+    
+    Since these man pages are short, rewriting them was quick enough.
+    Now xz-man.pot is entirely under 0BSD and marking the per-file
+    licenses is simpler.
+    
+    As a bonus, some wording hopefully is now slightly better
+    although it's perhaps a matter of taste.
+    
+    NOTE: In xzgrep.1, the EXIT STATUS section was written by me
+    in the commit d796b6d7fdb8b7238b277056cf9146cce25db604 so that's
+    why that section could be taken as is from the old xzgrep.1.

+    xzless: Update man page slightly.
+    
+    The xz tool can decompress three file formats and xzless
+    has always supported uncompressed files too.

+    liblzma: Include the SPDX license identifier 0BSD to generated files.
+    
+    Perhaps the generated files aren't even copyrightable but
+    using the same license for them as for the rest of the liblzma
+    keeps things more consistent for tools that look for license info.

+commit 76946dc4336c831fe2cc26696a035d807dd3cf13
+Author: Lasse Collin <lasse.collin@tukaani.org>
+Date:   2024-02-09 17:20:31 +0200
+
+    Fix SHA-256 authors.
+    
+    The initial commit 5d018dc03549c1ee4958364712fb0c94e1bf2741
+    in 2007 had a comment in sha256.c that the code is based on
+    Crypto++ Library 5.5.1. In 2009 the Authors list in sha256.c
+    and the AUTHORS file was updated with information that the
+    code had come from Crypto++ but via 7-Zip. I know I had viewed
+    7-Zip's SHA-256 code but back then the C code has been identical
+    enough with Crypto++, so I don't why I thought the author info
+    would need that extra step via 7-Zip for this single file.
+    
+    Another error is that I had mixed sha.* and shacal2.* files
+    when checking for author info in Crypto++. The shacal2.* files
+    aren't related to liblzma's sha256.c and thus Kevin Springle's
+    code in Crypto++ isn't either.

+    liblzma: Rename crc32_aarch64.h to crc32_arm64.h.
+    
+    Even though the proper name for the architecture is aarch64, this
+    project uses ARM64 throughout. So the rename is for consistency.
+    
+    Additionally, crc32_arm64.h was slightly refactored for the following
+    changes:
+    
+       * Added MSVC, FreeBSD, and macOS support in
+         is_arch_extension_supported().
+    
+       * crc32_arch_optimized() now checks the size when aligning the
+         buffer.
+    
+       * crc32_arch_optimized() loop conditions were slightly modified to
+         avoid both decrementing the size and incrementing the buffer
+         pointer.
+    
+       * Use the intrinsic wrappers defined in <arm_acle.h> because GCC and
+         Clang name them differently.
+    
+       * Minor spacing and comment changes.

+    liblzma: Refactor crc_common.h.
+    
+    The CRC_GENERIC is now split into CRC32_GENERIC and CRC64_GENERIC, since

+    
+    For the same reason, CRC_ARCH_OPTIMIZED is split into
+    CRC32_ARCH_OPTIMIZED and CRC64_ARCH_OPTIMIZED.
+    
+    ifunc will only be used with x86-64 CLMUL because the runtime detection
+    methods needed with ARM64 are not compatible with ifunc.

+
+    Speed up CRC32 calculation on ARM64
+    
+    The CRC32 instructions in ARM64 can calculate the CRC32 result
+    for 8 bytes in a single operation, making the use of ARM64
+    instructions much faster compared to the general CRC32 algorithm.
+    
+    Optimized CRC32 will be enabled if ARM64 has CRC extension
+    running on Linux.

+    Move doc/logo/xz-logo.png to "doc" and Doxygen footer to "doxygen".
+    
+    The footer isn't a complete HTML file so having it in the doxygen
+    directory is a tiny bit clearer.

+    
+    The PROJECT_LOGO field is now used to include the XZ logo. The footer
+    of each page now lists the copyright information instead of the default

+    xz: Use threaded mode by defaut (as if --threads=0 was used).
+    
+    This hopefully does more good than bad:
+    
+      + It's faster by default.
+    
+      + Only the threaded compressor creates files that
+        can be decompressed in threaded mode.
+    
+      - Compression ratio is worse, usually not too much though.
+        When it matters, -T1 must be used.
+    
+      - Memory usage increases.
+    
+      - Scripts that assume single-threaded mode but don't use -T1 will
+        possibly use too much resources, for example, if they run
+        multiple xz processes in parallel to compress multiple files.
+    
+      - Output from single-threaded and multi-threaded compressors
+        differ but such changes could happen for other reasons too
+        (they just haven't happened since 5.0.0).

+    liblzma: RISC-V filter: Use byte-by-byte access.
+    
+    Not all RISC-V processors support fast unaligned access so
+    it's better to read only one byte in the main loop. This can
+    be faster even on x86-64 when compared to reading 32 bits at
+    a time as half the time the address is only 16-bit aligned.
+    
+    The downside is larger code size on archs that do support
+    fast unaligned access.

+    liblzma: Rename arch-specific CRC functions and macros.
+    
+    CRC_CLMUL was split to CRC_ARCH_OPTIMIZED and CRC_X86_CLMUL.
+    CRC_ARCH_OPTIMIZED is defined when an arch-optimized version is used.
+    Currently the x86 CLMUL implementations are the only arch-optimized
+    versions, and these also use the CRC_x86_CLMUL macro to tell when
+    crc_x86_clmul.h needs to be included.
+    
+    is_clmul_supported() was renamed to is_arch_extension_supported().
+    crc32_clmul() and crc64_clmul() were renamed to
+    crc32_arch_optimized() and crc64_arch_optimized().
+    This way the names make sense with arch-specific non-CLMUL
+    implementations as well.

+
+    liblzma: Avoid extern lzma_crc32_clmul() and lzma_crc64_clmul().
+    
+    A CLMUL-only build will have the crcxx_clmul() inlined into
+    lzma_crcxx(). Previously a jump to the extern lzma_crcxx_clmul()
+    was needed. Notes about shared liblzma on ELF platforms:
+    
+      - On platforms that support ifunc and -fvisibility=hidden, this
+        was silly because CLMUL-only build would have that single extra
+        jump instruction of extra overhead.
+    
+      - On platforms that support neither -fvisibility=hidden nor linker
+        version script (liblzma*.map), jumping to lzma_crcxx_clmul()
+        would go via PLT so a few more instructions of overhead (still
+        not a big issue but silly nevertheless).
+    
+    There was a downside with static liblzma too: if an application only
+    needs lzma_crc64(), static linking would make the linker include the
+    CLMUL code for both CRC32 and CRC64 from crc_x86_clmul.o even though
+    the CRC32 code wouldn't be needed, thus increasing code size of the
+    executable (assuming that -ffunction-sections isn't used).
+    
+    Also, now compilers are likely to inline crc_simd_body()
+    even if they don't support the always_inline attribute
+    (or MSVC's __forceinline). Quite possibly all compilers
+    that build the code do support such an attribute. But now
+    it likely isn't a problem even if the attribute wasn't supported.
+    
+    Now all x86-specific stuff is in crc_x86_clmul.h. If other archs
+    The other archs can then have their own headers with their own
+    is_clmul_supported() and crcxx_clmul().
+    
+    Another bonus is that the build system doesn't need to care if
+    crc_clmul.c is needed.
+    
+    is_clmul_supported() stays as inline function as it's not needed
+    when doing a CLMUL-only build (avoids a warning about unused function).

+    liblzma: Use 8-byte method in memcmplen.h on ARM64.
+    
+    It requires fast unaligned access to 64-bit integers
+    and a fast instruction to count leading zeros in
+    a 64-bit integer (__builtin_ctzll()). This perhaps
+    should be enabled on some other archs too.
+    
+    Thanks to Chenxi Mao for the original patch:
+    https://github.com/tukaani-project/xz/pull/75 (the first commit)
+    According to the numbers there, this may improve encoding
+    speed by about 3-5 %.
+    
+    This enables the 8-byte method on MSVC ARM64 too which
+    should work but wasn't tested.

+
+    CMake: Move sandbox detection outside of xz section.
+    
+    The sandbox is now enabled for xzdec as well, so it no longer belongs
+    in just the xz section. xz and xzdec are always built, except for older
+    MSVC versions, so there isn't a need to conditionally show the sandbox
+    configuration. CMake will do a little unecessary work on older MSVC
+    versions that can't build xz or xzdec, but this is a very small
+    downside.

+
+    xzdec: Add sandbox support for Pledge, Capsicum, and Landlock.
+    
+    A very strict sandbox is used when the last file is decompressed. The
+    likely most common use case of xzdec is to decompress a single file.
+    The Pledge sandbox is applied to the entire process with slightly more
+    relaxed promises, until the last file is processed.
+    
+    Thanks to Christian Weisgerber for the initial patch adding Pledge
+    sandboxing.

+    liblzma: Initialize lzma_lz_encoder pointers with NULL.
+    
+    This fixes the recent change to lzma_lz_encoder that used memzero
+    instead of the NULL constant. On some compilers the NULL constant
+    (always 0) may not equal the NULL pointer (this only needs to guarentee
+    to not point to valid memory address).
+    
+    Later code compares the pointers to the NULL pointer so we must
+    initialize them with the NULL pointer instead of 0 to guarentee
+    code correctness.

+
+    liblzma: Set all values in lzma_lz_encoder to NULL after allocation.
+    
+    The first member of lzma_lz_encoder doesn't necessarily need to be set
+    to NULL since it will always be set before anything tries to use it.
+    However the function pointer members must be set to NULL since other
+    functions rely on this NULL value to determine if this behavior is
+    supported or not.
+    
+    This fixes a somewhat serious bug, where the options_update() and
+    set_out_limit() function pointers are not set to NULL. This seems to
+    have been forgotten since these function pointers were added many years
+    after the original two (code() and end()).
+    
+    The problem is that by not setting this to NULL we are relying on the
+    memory allocation to zero things out if lzma_filters_update() is called
+    on a LZMA1 encoder. The function pointer for set_out_limit() is less
+    serious because there is not an API function that could call this in an
+    incorrect way. set_out_limit() is only called by the MicroLZMA encoder,
+    which must use LZMA1 where set_out_limit() is always set. Its currently
+    not possible to call set_out_limit() on an LZMA2 encoder at this time.
+    
+    So calling lzma_filters_update() on an LZMA1 encoder had undefined
+    behavior since its possible that memory could be manipulated so the
+    options_update member pointed to a different instruction sequence.
+    
+    This is unlikely to be a bug in an existing application since it relies
+    on calling lzma_filters_update() on an LZMA1 encoder in the first place.
+    For instance, it does not affect xz because lzma_filters_update() can
+    only be used when encoding to the .xz format.
+    
+    This is fixed by using memzero() to set all members of lzma_lz_encoder
+    to NULL after it is allocated. This ensures this mistake will not occur
+    here in the future if any additional function pointers are added.

+    liblzma: Make parameter names in function definition match declaration.
+    
+    lzma_raw_encoder() and lzma_raw_encoder_init() used "options" as the
+    parameter name instead of "filters" (used by the declaration). "filters"
+    is more clear since the parameter represents the list of filters passed
+    to the raw encoder, each of which contains filter options.

+        uint8_t a = 5;
+        uint32_t b = (a + 5) * 2;
+

+
+    Tests: Minor cleanups to OSS-Fuzz files.
+    
+    Most of these fixes are small typos and tweaks. A few were caused by bad
+    advice from me. Here is the summary of what is changed:
+    
+    - Author line edits
+    
+    - Small comment changes/additions
+    
+    - Using the return value in the error messages in the fuzz targets'
+      coder initialization code
+    
+    - Removed fuzz_encode_stream.options. This set a max length, which may
+      prevent some worthwhile code paths from being properly exercised.
+    
+    - Removed the max_len option from fuzz_decode_stream.options for the
+      same reason as fuzz_encode_stream. The alone decoder fuzz target still
+      has this restriction.
+    
+    - Altered the dictionary contents for fuzz_lzma.dict. Instead of keeping
+      the properties static and varying the dictionary size, the properties
+      are varied and the dictionary size is kept small. The dictionary size
+      doesn't have much impact on the code paths but the properties do.
+    
+    Closes: https://github.com/tukaani-project/xz/pull/73

+
+    Build: Change --enable-ifunc handling.
+    
+    Some compilers support __attribute__((__ifunc__())) even though the
+    dynamic linker does not. The compiler is able to create the binary
+    but it will fail on startup. So it is not enough to just test if
+    the attribute is supported.
+    
+    The default value for enable_ifunc is now auto, which will attempt
+    to compile a program using __attribute__((__ifunc__())). There are
+    additional checks in this program if glibc is being used or if it
+    is running on FreeBSD.
+    
+    Setting --enable-ifunc will skip this test and always enable
+    __attribute__((__ifunc__())), even if is not supported.

+
+    xz: Create separate is_tty() function.
+    
+    The new is_tty() will report if a file descriptor is a terminal or not.
+    On POSIX systems, it is a wrapper around isatty(). However, the native
+    Windows implementation of isatty() will return true for all character
+    devices, not just terminals. So is_tty() has a special case for Windows
+    so it can use alternative Windows API functions to determine if a file
+    descriptor is a terminal.
+    
+    This fixes a bug with MSVC and MinGW-w64 builds that refused to read from
+    or write to non-terminal character devices because xz thought it was a
+    terminal. For instance:
+    
+        xz foo -c > /dev/null
+    
+    would fail because /dev/null was assumed to be a terminal.

+    xz: Fix a bug with --files and --files0 in raw mode without a suffix.
+    
+    The following command caused a segmentation fault:
+    
+        xz -Fraw --lzma1 --files=foo
+    
+    when foo was a valid file. The usage of --files or --files0 was not
+    being checked when compressing or decompressing in raw mode without a
+    suffix. The suffix checking code was meant to validate that all files
+    to be processed are "-" (if not writing to standard out), meaning the
+    data is only coming from standard in. In this case, there were no file
+    names to check since --files and --files0 store their file name in a
+    different place.
+    
+    Later code assumed the suffix was set and caused a segmentation fault.
+    Now, the above command results in an error.

+    xz: Refactor suffix test with raw format.
+    
+    The previous version set opt_stdout, but this caused an issue with
+    copying an input file to standard out when decompressing an unknown file
+    type. The following needs to result in an error:
+    
+        echo foo | xz -df

+    since -c, --stdout is not used. This fixes the previous error by not

+    Build: Detect -fsanitize= in CFLAGS and incompatible build options.
+    
+    Now configure will fail if -fsanitize= is found in CFLAGS
+    and sanitizer-incompatible ifunc or Landlock sandboxing
+    would be used. These are incompatible with one or more sanitizers.
+    It's simpler to reject all -fsanitize= uses instead of trying to

+    
+    CMake-based build was updated similarly. It lets the configuration
+    finish (SEND_ERROR instead of FATAL_ERROR) so that both error
+    messages can be seen at once.

+    
+    The sandboxing on Linux now supports Landlock, which restricts all

+    standard out. With fsanitize=address,undefined, the instrumentation

+    xz: Support basic sandboxing with Linux Landlock (ABI versions 1-3).
+    
+    It is enabled only when decompressing one file to stdout,
+    similar to how Capsicum is used.
+    
+    Landlock was added in Linux 5.13.

+    Simplify detection of Capsicum support.
+    
+    This removes support for FreeBSD 10.0 and 10.1 which used
+    <sys/capability.h> instead of <sys/capsicum.h>. Support for
+    FreeBSD 10.1 ended on 2016-12-31. So now FreeBSD >= 10.2 is
+    required to enable Capsicum support.
+    
+    This also removes support for Capsicum on Linux (libcaprights)
+    which seems to have been unmaintained since 2017 and Linux 4.11:

+
+    xz/Windows: Ensure that clock_gettime() isn't used with MinGW-w64.
+    
+    This commit alone doesn't change anything in the real-world:
+    
+      - configure.ac currently checks for clock_gettime() only
+        when using pthreads.
+    
+      - CMakeLists.txt doesn't check for clock_gettime() on Windows.
+    
+    So clock_gettime() wasn't used with MinGW-w64 before either.
+    
+    clock_gettime() provides monotonic time and it's better than
+    gettimeofday() in this sense. But clock_gettime() is defined
+    in winpthreads, and liblzma or xz needs nothing else from
+    winpthreads. By avoiding clock_gettime(), we avoid the dependency on
+    libwinpthread-1.dll or the need to link against the static version.
+    
+    As a bonus, GetTickCount64() and MinGW-w64's gettimeofday() can be
+    faster than clock_gettime(CLOCK_MONOTONIC, &tv). The resolution
+    is more than good enough for the progress indicator in xz.

+
+    liblzma: Move is_clmul_supported() back to crc_common.h.
+    
+    This partially reverts creating crc_clmul.c
+    (8c0f9376f58c0696d5d6719705164d35542dd891) where is_clmul_supported()
+    was moved, extern'ed, and renamed to lzma_is_clmul_supported(). This
+    caused a problem when the function call to lzma_is_clmul_supported()
+    results in a call through the PLT. ifunc resolvers run very early in
+    the dynamic loading sequence, so the PLT may not be setup properly at
+    this point. Whether the PLT is used or not for
+    lzma_is_clmul_supported() depened upon the compiler-toolchain used and
+    flags.
+    
+    In liblzma compiled with GCC, for instance, GCC will go through the PLT
+    for function calls internal to liblzma if the version scripts and
+    symbol visibility hiding are not used. If lazy-binding is disabled,
+    then it would have made any program linked with liblzma fail during
+    dynamic loading in the ifunc resolver.

+    liblzma: Fix -fsanitize=address failure with crc_clmul functions.
+    
+    After forcing crc_simd_body() to always be inlined it caused
+    -fsanitize=address to fail for lzma_crc32_clmul() and
+    lzma_crc64_clmul(). The __no_sanitize_address__ attribute was added
+    to lzma_crc32_clmul() and lzma_crc64_clmul(), but not removed from
+    crc_simd_body(). ASAN and inline functions behavior has changed over
+    the years for GCC specifically, so while strictly required we will
+    keep __attribute__((__no_sanitize_address__)) on crc_simd_body() in
+    case this becomes a requirement in the future.
+    
+    Older GCC versions refuse to inline a function with ASAN if the
+    caller and callee do not agree on sanitization flags
+    (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89124#c3). If the
+    function was forced to be inlined, it will not compile if the callee
+    function has __no_sanitize_address__ but the caller doesn't.

+    This macro must be used instead of the inline keyword. On MSVC, it is

+    It does not use a build system check to determine if

+    
+    Also, it encapsulates the complexity of the CLMUL implementations into a

+    CMake/Windows: Fix when the windres workaround is applied.
+    
+    CMake doesn't set WIN32 on CYGWIN but the workaround is
+    probably needed on Cygwin too. Same for MSYS and MSYS2.
+    
+    The workaround must not be used with Clang that is acting in
+    MSVC mode. This fixes it by checking for the known environments
+    that need the workaround instead of using "NOT MSVC".
+    
+    Thanks to Martin Storsjö.

+    CI: Disable CLANG64 MSYS2 environment until bug is resolved.
+    
+    lld 17.0.1 searches for libraries to link first in the toolchain
+    directories before the local directory when building. The is a problem
+    for us because liblzma.a is installed in MSYS2 CLANG64 by default and
+    xz.exe will thus use the installed library instead of the one being
+    built.
+    
+    This causes tests to fail when they are expecting features to be
+    disabled. More importantly, it will compile xz.exe with an incorrect
+    liblzma and could cause unexpected behavior by being unable to update
+    liblzma code in static builds. The CLANG64 environment can be tested
+    again once this is fixed.
+    
+    Link to bug: https://github.com/llvm/llvm-project/issues/67779.

+    
+    At CMake side there is add_compile_options(-Wall -Wextra)

+    This is not a full fix as things like -Wunused-macros in

     these two tests because these tests must use -Werror.
     CC=clang CFLAGS=-Weverything is the most extreme example.
     It enables -Wreserved-macro-identifier which warns about
+    #define __EXTENSIONS__ 1 because it begins with two underscores.
     It's possible to write a test file that passes -Weverything but
     it becomes impossible when Autoconf inserts confdefs.h.
     
     So this commit adds AC_LANG_SOURCE to silence Autoconf warnings.
     A different solution is needed for -Werror tests.

+    lib: Update getopt.in.h from Gnulib with modifications.
+    
+    We can still avoid modifying the contents of this file during
+    configuration to simplify the build systems. Gnulib added replacements
+    for inclusions guards for Cygwin. Cygwin should not need getopt_long
+    replacement so this feature can be omitted.
+    
+    <unistd.h> is conditionally included to avoid MSVC since it is not
+    available.
+    
+    The definition for _GL_ARG_NONNULL was also copied into this file from
+    Gnulib since this stage is usually done during gnulib-tool.

+    lib: Add getopt-cdefs.h for getopt_long update.
+    
+    This was modified slightly from Gnulib. In Gnulib, it expects the
+    @HAVE_SYS_CDEFS_H@ to be replaced. Instead, we can set HAVE_SYS_CDEFS_H
+    on systems that have it and avoid copying another file into the build
+    directory. Since we are not using gnulib-tool, copying extra files
+    requires extra build system updates (and special handling with CMake) so
+    we should avoid when possible.

+    
+    VS2013 update 2 should still be able to build liblzma.

+    tuklib: Update tuklib_attr_noreturn for C11/C17 and C23.
+    
+    This makes no difference for GCC or Clang as they support
+    GNU C's __attribute__((__noreturn__)) but this helps with MSVC:
+    
+      - VS 2019 version 16.7 and later support _Noreturn if the
+        options /std:c11 or /std:c17 are used. This gets handled
+        with the check for __STDC_VERSION__ >= 201112.
+    
+      - When MSVC isn't in C11/C17 mode, __declspec(noreturn) is used.
+    
+    C23 will deprecate _Noreturn (and <stdnoreturn.h>)
+    for [[noreturn]]. This commit anticipates that but
+    the final __STDC_VERSION__ value isn't known yet.

+    The crc64_clmul() function should be ignored by the address sanitizer

+    CI: Update ci_build.sh CMake to always make Unix Makefiles.
+    
+    The default for many of the MSYS2 environments is for CMake to create

+    need a different command to run the tests. Its simpler to always use
+    Unix Makefiles so that "make test" is always a usable target for

+    encoders, and decoders.
+    
+    The Windows runner will only be run manually since these tests will
+    likely take much longer than the Linux and MacOS runners. This runner
+    should be used before merging any large features and before releases.
+    
+    Currently the clang64 environment fails to due to a warning and
+    -Werror is enabled for the CI tests. This is still an early version
+    since the CMake build can be done for MSVC and optionally each of the
+    MSYS2 environments. GitHub does not allow manually running the CI tests
+    unless the workflow is checked on the default branch so checking in a
+    minimum version is a good idea.
+    
+    Thanks to Arthur S for the original proposing the original patch.

-    xz: Update man page Authors and date.
+    liblzma: Suppress -Wunused-function warning.
+    
+    Clang 16.0.0 and earlier have a bug that the ifunc resolver function
+    triggers the -Wunused-function warning. The resolver function is static
+    and only "used" by the __attribute__((__ifunc()__)).
+    
+    At this time, the bug is still unresolved, but has been reported:
+    https://github.com/llvm/llvm-project/issues/63957
+    
+    This is not a problem in GCC.

-    liblzma: Prevent warning for MSYS2 Windows build.
-    
-    In lzma_memcmplen(), the <intrin.h> header file is only included if
-    _MSC_VER and _M_X64 are both defined but _BitScanForward64() was
-    previously used if _M_X64 was defined. GCC for MSYS2 defines _M_X64 but
-    not _MSC_VER so _BitScanForward64() was used without including
-    <intrin.h>.
-    
-    Now, lzma_memcmplen() will use __builtin_ctzll() for MSYS2 GCC builds as
-    expected.

+    xz: Add a new --filters-help option.
+    
+    The --filters-help can be used to help create filter chains with the
+    --filters and --filtersX options. The message in --long-help is too
+    short to fully explain the syntax to construct complex filter chains.
+    
+    In --robot mode, xz will only print the output from liblzma function
+    lzma_str_list_filters.

+
+    xz: Ignore filter chains that are set but never used in --block-list.
+    
+    If a filter chain is set but not used in --block-list, it introduced
+    unexpected behavior such as requiring an unneeded amount of memory to
+    compress, reducing the number of threads in multi-threaded encoding, and
+    printing an incorrect amount of memory needed to decompress.
+    
+    This also renames filters_init_mask => filters_used_mask. A filter is
+    assumed to be used if it is specified in --filtersX until
+    coder_set_compression_settings() determines which filters are referenced
+    in --block-list.

+    xz: Set the Block size for mt encoding correctly.
+    
+    When opt_block_size is not used, the Block size for mt encoder is
+    derived from the minimum of the largest Block specified by
+    --block-list and the recommended Block size on all filter chains
+    calculated by lzma_mt_block_size(). This avoids using unnecessary

+    xz: Create command line options for filters[1-9].
+    
+    The new command line options are meant to be combined with --block-list.
+    They work as an optional extension to --block-list to specify a custom

+    of up to 9 reusable filter chains. For instance:
+

+    --filters2=x86--lzma2 --filters3=arm64--lzma2
+    
+    Will create the following blocks:
+    1. A block of size 10 MiB with filter chain delta, lzma2.
+    2. A block of size 5 MiB with filter chain arm64, lzma2.
+    3. A block of size 5 MiB with filter chain arm64, lzma2.
+    4. A block of size 5 MiB with filter chain x86, lzma2.
+    5. A block containing the rest of the file contents with filter chain
+       delta, lzma2.

+    liblzma: Add ifunc implementation to crc64_fast.c.
+    
+    The ifunc method avoids indirection via the function pointer
+    crc64_func. This works on GNU/Linux and probably on FreeBSD too.
+    The previous __attribute((__constructor__)) method is kept for
+    compatibility with ELF platforms which do support ifunc.
+    
+    The ifunc method has some limitations, for example, building
+    liblzma with -fsanitize=address will result in segfaults.
+    The configure option --disable-ifunc must be used for such builds.
+    
+    Thanks to Hans Jansen for the original patch.

     Boost iostream uses `find_package` in quiet mode and then again uses
     `find_package` with required. This second call triggers a
-    `add_library cannot create imported target "LibLZMA::LibLZMA"
-    because another target with the same name already exists.`
+    `add_library cannot create imported target "ZLIB::ZLIB" because another
+    target with the same name already exists.`
     
     This can simply be fixed by skipping the alias part on secondary
     `find_package` runs.

+    
+    Reword "options required" to "supported options". The previous may have
+    suggested that the options listed were all required anytime a filter is
+    used for encoding or decoding. The reword makes this more clear that
+    adjusting the options is optional.

-    Translations: Update the Croatian translation.
+    liblzma: Exports lzma_mt_block_size() as an API function.
+    
+    The lzma_mt_block_size() was previously just an internal function for
+    the multithreaded .xz encoder. It is used to provide a recommended Block
+    size for a given filter chain.
+    
+    This function is helpful to determine the maximum Block size for the
+    multithreaded .xz encoder when one wants to change the filters between
+    blocks. Then, this determined Block size can be provided to
+    lzma_stream_encoder_mt() in the lzma_mt options parameter when
+    intializing the coder. This requires one to know all the filter chains
+    they are using before starting to encode (or at least the filter chain
+    that will need the largest Block size), but that isn't a bad limitation.

+
+    CI: Removes CMakeCache.txt between builds.
+    
+    If the cache file is not removed, CMake will not reset configurations
+    back to their default values. In order to make the tests independent, it
+    is simplest to purge the cache. Unfortunatly, this will slow down the
+    tests a little and repeat some checks.

+    CI: Runs CMake feature tests.
+    
+    Now, CMake will run similar feature disable tests that the Autotools
+    version did before. In order to do this without repeating lines in
+    ci.yml, it now makes sense to use the GitHub Workflow matrix to create
+    a loop.

+
+    CI: Change ci_build.sh to use bash instead of sh.
+    
+    This script is only meant to be run as part of the CI build/test process
+    on machines that are known to have bash (Ubuntu and MacOS). If this
+    assumption changes in the future, then the bash specific commands will
+    need to be replaced with a more portable option. For now, it is
+    convenient to use bash commands.

-    xz: Don't fail if Capsicum is enabled but kernel doesn't support it.
-    
-    (This commit combines related commits from the master branch.)
-    
-    If Capsicum support is missing from the kernel or xz is being run
-    in an emulator that lacks Capsicum suport, the syscalls will fail
-    and set errno to ENOSYS. Previously xz would display and error and
-    exit, making xz unusable. Now it will check for ENOSYS and run
-    without sandbox support. Other tools like ssh behave similarly.
-    
-    Displaying a warning for missing Capsicum support was considered
-    but such extra output would quickly become annoying. It would also
-    break test_scripts.sh in "make check".
-    
-    Also move cap_enter() to be the first step instead of the last one.
-    This matches the example in the cap_rights_limit(2) man page. With
-    the current code it shouldn't make any practical difference though.
+    Revert: "Add warning if Capsicum sandbox system calls are unsupported."
     
-    Thanks to Xin Li for the bug report, suggesting a fix, and testing:
-    https://github.com/tukaani-project/xz/pull/43
+    The warning causes the exit status to be 2, so this will cause problems
+    for many scripted use cases for xz. The sandbox usage is already very
+    limited already, so silently disabling this allows it to be more usable.

-    Build: Adjust CMake version search regex.
+    xz: Add warning if Capsicum sandbox system calls are unsupported.
     
-    Now, the LZMA_VERSION_MAJOR, LZMA_VERSION_MINOR, and LZMA_VERSION_PATCH
-    macros do not need to be on consecutive lines in version.h. They can be
-    separated by more whitespace, comments, or even other content, as long
-    as they appear in the proper order (major, minor, patch).
+    The warning is only used when errno == ENOSYS. Otherwise, xz still
+    issues a fatal error.

-    liblzma: Improve documentation for version.h.
+    xz: Skip Capsicum sandbox system calls when they are unsupported.
     
-    Specified parameter and return values for API functions and documented
-    a few more of the macros.
+    If a system has the Capsicum header files but does not actually
+    implement the system calls, then this would render xz unusable. Instead,
+    we can check if errno == ENOSYS and not issue a fatal error.

+    xz: Add SIGTSTP handler for progress indicator time keeping.
+    
+    This way, if xz is stopped the elapsed time and estimated time
+    remaining won't get confused by the amount of time spent in
+    the stopped state.
+    
+    This raises SIGSTOP. It's not clear to me if this is the correct way.
+    POSIX and glibc docs say that SIGTSTP shouldn't stop the process if
+    it is orphaned but this commit doesn't attempt to handle that.
+    
+    Search for SIGTSTP in section 2.4.3:

+    tuklib_physmem: Check for __has_warning before GCC version.
+    
+    Clang can be configured to fake a too high GCC version so
+    this way it's more robust.

+    Revert "tuklib_common: Define __has_warning if it is not defined."
+    
+    This reverts commit 82e3c968bfa10e3ff13333bd9cbbadb5988d6766.
+    
+    Macros in the reserved namespace (_foo or __foo) shouldn't be #defined
+    without a very good reason. Here the alternative would have been
+    to #define tuklib_has_warning(str) to an approriate value.
+    
+    Also the tuklib_* files should stay namespace clean if possible.

+
+    tuklib_physmem: Clean up the way -Wcast-function-type is silenced on Windows.
+    
+    __has_warning and other __has_foo macros are meant to become
+    compiler-agnostic so it's not good to check for __clang__ with it.
+    
+    This also relied on tuklib_common.h for #defining __has_warning
+    which was confusing as #defining reserved macros is generally
+    not a good idea.

+    Doxygen: Update Doxyfile.in from 1.4.7 to 1.8.17.
+    
+    A few Doxygen tags were obsolete from 1.4.7. Version 1.8.17 released
+    in 2019, so this should be compatible with resonable modern distros.
+    The purpose of Doxygen these days is for docs on the website, so it
+    doesn't necessarily have to work for everyone. Just when the maintainers

-    xz: Include <strings.h> in suffix.c if needed for strcasecmp().
-    
-    SUSv2 and POSIX.1‐2017 declare only a few functions in <strings.h>.
-    Of these, strcasecmp() is used on some platforms in suffix.c.
-    Nothing else in the project needs <strings.h> (at least if
-    building on a modern system).
-    
-    sysdefs.h currently includes <strings.h> if HAVE_STRINGS_H is
-    defined and suffix.c relied on this.
-    
-    Note that dos/config.h doesn't #define HAVE_STRINGS_H even though
-    DJGPP does have strings.h. It isn't needed with DJGPP as strcasecmp()
-    is also in <string.h> in DJGPP.

-    This is combined from the following commits in the master branch:
-    443dfebced041adc88f10d824188eeef5b5821a9
-    6b117d3b1fe91eb26d533ab16a2e552f84148d47

+    It's a string, not a list. It only worked when the variable was empty.
     
-    Thanks to Iouri Kharon for the bug report, the original patch,
-    and testing.

+
+    CMake: Fix windres issues again.
+    
+    At least on some systems, GNU windres needs --use-temp-file
+    in addition to the \x20 hack to avoid spaces in the command line
+    argument. Hovever, that \x20 syntax is broken with llvm-windres
+    version 15.0.0 (results in "XZx20Utils") but luckily it works
+    with a regular space. Thus it is best to limit the workarounds
+    to GNU toolchain on Windows.

-    common/index.h is needed by liblzma internally and tests. common.h will
-    include and define many things that are not needed by the tests.
+    The old version used too many runners that resulted in unnecessary
+    dependency downloads. Now, the runners are reused for the different
+    configurations for each OS and build system.

+
+    CI/CD: Add new -p (PHASE) argument to ci_build.sh
     
-    Also, this prevents include order problems because both common.h and
-    lzma.h define LZMA_API. On most platforms it results only in a warning
-    but on Windows it would break the build as the definition in common.h
-    must be used only for building liblzma itself.
+    The new PHASE argument can be build, test, or all. all is the default.
+    This way, the CI/CD script can differentiate between the build and test
+    phases to make it easier to track down errors when they happen.

-    Update INSTALL: CMake on Windows isn't experimental anymore.
-    
-    Using CMake to build liblzma should work on a few other OSes
-    but building the command line tools is still subtly broken.
-    
-    It is known that shared library versioning may differ between
-    CMake and Libtool builds on some OSes, most notably Darwin.

-    xz: Don't modify argv[].

-    liblzma: Check for unexpected NULL pointers in block_header_decode().
-    
-    The API docs gave an impression that such checks are done
-    but they actually weren't done. In practice it made little
-    difference since the calling code has a bug if these are NULL.
-    
-    Thanks to Jia Tan for the original patch that checked for

-    liblzma: Use __has_attribute(__symver__) to fix Clang detection.
-    
-    If someone sets up Clang to define __GNUC__ to 10 or greater
-    then symvers broke. __has_attribute is supported by such GCC
-    and Clang versions that don't support __symver__ so this should
-    be much better and simpler way to detect if __symver__ is

-    liblzma: Omit zero-skipping from ARM64 filter.
-    
-    It has some complicated downsides and its usefulness is more limited
-    than I originally thought. So this change is bad for certain very
-    specific situations but a generic solution that works for other
-    filters (and is otherwise better too) is planned anyway. And this
-    way 7-Zip can use the same compatible filter for the .7z format.
-    
-    This is still marked as experimental with a new temporary Filter ID.

-    liblzma: Add lzma_str_to_filters, _from_filters, and _list_filters.
-    
-    lzma_str_to_filters() uses static error messages which makes
-    them not very precise. It tells the position in the string
-    where an error occurred though which helps quite a bit if
-    applications take advantage of it. Dynamic error messages can
-    be added later with a new flag if it seems important enough.

-Author: Lasse Collin <lasse.collin@tukaani.org>
-Date:   2022-11-27 23:16:21 +0200
-
-    liblzma: Add LZMA_FILTER_LZMA1EXT to support LZMA1 without end marker.
-    
-    Some file formats need support for LZMA1 streams that don't use
-    the end of payload marker (EOPM) alias end of stream (EOS) marker.
-    So far liblzma API has supported decompressing such streams via
-    lzma_alone_decoder() when .lzma header specifies a known
-    uncompressed size. Encoding support hasn't been available in the API.
-    
-    Instead of adding a new LZMA1-only API for this purpose, this commit
-    adds a new filter ID for use with raw encoder and decoder. The main
-    benefit of this approach is that then also filter chains are possible,
-    for example, if someone wants to implement support for .7z files that
-    use the x86 BCJ filter with LZMA1 (not BCJ2 as that isn't supported
-    in liblzma).

-    Build: Don't put GNU/Linux-specific symbol versions into static liblzma.
-    
-    It not only makes no sense to put symbol versions into a static library
-    but it can also cause breakage.
-    
-    By default Libtool #defines PIC if building a shared library and
-    doesn't define it for static libraries. This is documented in the
-    Libtool manual. It can be overriden using --with-pic or --without-pic.
-    configure.ac detects if --with-pic or --without-pic is used and then
-    gives an error if neither --disable-shared nor --disable-static was
-    used at the same time. Thus, in normal situations it works to build
-    both shared and static library at the same time on GNU/Linux,
-    only --with-pic or --without-pic requires that only one type of
-    library is built.
-    
-    Thanks to John Paul Adrian Glaubitz from Debian for reporting
-    the problem that occurred on ia64:

-    liblzma: Refactor to use lzma_filters_free().
-    
-    lzma_filters_free() sets the options to NULL and ids to
-    LZMA_VLI_UNKNOWN so there is no need to do it by caller;
-    the filter arrays will always be left in a safe state.
-    
-    Also use memcpy() instead of a loop to copy a filter chain
-    when it is known to be safe to copy LZMA_FILTERS_MAX + 1
-    (even if the elements past the terminator might be uninitialized).

-    liblzma: Fix another invalid free() after memory allocation failure.

-    This time it can happen when lzma_stream_encoder_mt() is used

-    It's very similar to the previous bug

-    an array of lzma_filter structures whose old options are freed

-
-    liblzma: Fix invalid free() after memory allocation failure.
-    
-    The bug was in the single-threaded .xz Stream encoder
-    in the code that is used for both re-initialization and for
-    lzma_filters_update(). To trigger it, an application had
-    to either re-initialize an existing encoder instance with
-    lzma_stream_encoder() or use lzma_filters_update(), and
-    then one of the 1-4 tiny allocations in lzma_filters_copy()
-    (called from stream_encoder_update()) must fail. An error
-    was correctly reported but the encoder state was corrupted.
-    
-    This is related to the recent fix in
-    f8ee61e74eb40600445fdb601c374d582e1e9c8a which is good but
-    it wasn't enough to fix the main problem in stream_encoder.c.

-    The encoder doesn't support dictionary sizes larger than 1536 MiB.
-    This is validated, for example, when calculating the memory usage
-    via lzma_raw_encoder_memusage(). It is also enforced by the LZ
-    part of the encoder initialization. However, LZMA encoder with
-    LZMA_MODE_NORMAL did an unsafe calculation with dict_size before
-    such validation and that results in an infinite loop if dict_size
-    was 2 << 30 or greater.

-    Revert "liblzma: Simple/BCJ filters: Allow disabling generic BCJ options."
-    
-    This reverts commit 177bdc922cb17bd0fd831ab8139dfae912a5c2b8
-    and also does equivalent change to arm64.c.
-    
-    Now that ARM64 filter will use lzma_options_bcj, this change
-    is not needed anymore.

-    Replace the experimental ARM64 filter with a new experimental version.
-    
-    This is incompatible with the previous version.
-    
-    This has space/tab fixes in filter_*.c and bcj.h too.

-Author: Lasse Collin <lasse.collin@tukaani.org>

-    liblzma: Add fast CRC64 for 32/64-bit x86 using SSSE3 + SSE4.1 + CLMUL.
-    
-    It also works on E2K as it supports these intrinsics.
-    
-    On x86-64 runtime detection is used so the code keeps working on
-    older processors too. A CLMUL-only build can be done by using
-    -msse4.1 -mpclmul in CFLAGS and this will reduce the library
-    size since the generic implementation and its 8 KiB lookup table
-    will be omitted.
-    
-    On 32-bit x86 this isn't used by default for now because by default
-    on 32-bit x86 the separate assembly file crc64_x86.S is used.
-    If --disable-assembler is used then this new CLMUL code is used
-    the same way as on 64-bit x86. However, a CLMUL-only build
-    (-msse4.1 -mpclmul) won't omit the 8 KiB lookup table on
-    32-bit x86 due to a currently-missing check for disabled
-    assembler usage.
-    
-    The configure.ac check should be such that the code won't be
-    built if something in the toolchain doesn't support it but
-    --disable-clmul-crc option can be used to unconditionally
-    disable this feature.
-    
-    CLMUL speeds up decompression of files that have compressed very
-    well (assuming CRC64 is used as a check type). It is know that
-    the CLMUL code is significantly slower than the generic code for
-    tiny inputs (especially 1-8 bytes but up to 16 bytes). If that
-    is a real-world problem then there is already a commented-out
-    variant that uses the generic version for small inputs.
-    
-    Thanks to Ilya Kurdyukov for the original patch which was
-    derived from a white paper from Intel [1] (published in 2009)
-    and public domain code from [2] (released in 2016).

-    Build: Omit x86_64 from --enable-assembler.
-    
-    It didn't do anything. There are only 32-bit x86 assembly files

-    in C are more portable across toolchains and OSes.

-    __SSE2__ is the correct macro for SSE2 support with GCC, Clang,

-    xz: Add --arm64 to --long-help and omit endianness from ARM(-Thumb).
-    
-    Modern 32-bit ARM in big endian mode use little endian for
-    instruction encoding still, so the filters work on such
-    executables too. It's likely less confusing for users this way.
-    
-    The --arm64 option hasn't been implemented yet (there is
-    --experimental-arm64 but it's different). The --arm64 option
-    is added now anyway because this is the likely result and the
-    strings need to be ready for translators.

-    xz: Add .lz (lzip) decompression support.
-    
-    If configured with --disable-lzip-decoder then --long-help will
-    still list `lzip' in --format but I left it like that since
-    due to translations it would be messy to have two help strings.
-    Features are disabled only in special situations so wrong help
-    in such a situation shouldn't matter much.
-

-
-    liblzma: Add .lz (lzip) decompression support (format versions 0 and 1).
-    
-    Support for format version 0 was removed from lzip 1.18 for some
-    reason. .lz format version 0 files are rare (and old) but some
-    source packages were released in this format, and some people might
-    have personal files in this format too. It's very little extra code
-    to support it along side format version 1 so this commits adds
-    support for both.
-    
-    The Sync Flush marker extentension to the original .lz format
-    version 1 isn't supported. It would require changes to the
-    LZMA decoder itself. Such files are very rare anyway.
-    
-    See the API doc for lzma_lzip_decoder() for more details about
-    the .lz format support.
-    
-    Thanks to Michał Górny for the original patch.

-    xz: Fix displaying of file sizes in progress indicator in passthru mode.
-    
-    It worked for one input file since the counters are zero when
-    xz starts but they weren't reset when starting a new file in
-    passthru mode. For example, if files A, B, and C are one byte each,
-    then "xz -dcvf A B C" would show file sizes as 1, 2, and 3 bytes
-    instead of 1, 1, and 1 byte.

-    liblzma: Include cached memory in reported memusage in threaded decoder.
-    
-    This affects lzma_memusage() and lzma_memlimit_set() when used
-    with the threaded decompressor. Now all allocations are reported
-    by lzma_memusage() (so it's not misleading) and lzma_memlimit_set()
-    cannot lower the limit below that value.
-    
-    The alternative would have been to allow lowering the limit if
-    doing so is possible by freeing the cached memory but since
-    the primary use case of lzma_memlimit_set() is to increase
-    memlimit after LZMA_MEMLIMIT_ERROR this simple approach
-    was selected.
-    
-    The cached memory was always included when enforcing
-    the memory usage limit while decoding.
-    
-    Thanks to Jia Tan.

-    is never needed by those builds. VS project files or

-    Now files with unsupported check will make xz display
-    a warning, set the exit status to 2 (unless --no-warn is used),
-    and then decompress the file normally. This is how it was
-    supposed to work since the beginning but this was broken by
-    the commit 231c3c7098f1099a56abb8afece76fc9b8699f05, that is,
-    a little before 5.0.0 was released. The buggy behavior displayed
-    a message, set exit status 1 (error), and xz didn't attempt to
-    to decompress the file.
-    
-    This doesn't matter today except for special builds that disable
-    CRC64 or SHA-256 at build time (but such builds should be used
-    in special situations only). The bug matters if new check type
-    is added in the future and an old xz version is used to decompress
-    such a file; however, it's likely that such files would use a new
-    filter too and an old xz wouldn't be able to decompress the file
-    anyway.
-    
-    The first hunk in the commit is the actual fix. The second hunk
-    is a cleanup since LZMA_TELL_ANY_CHECK isn't used in xz.
-    
-    There is a test file for unsupported check type but it wasn't
-    used by test_files.sh, perhaps due to different behavior between
-    xz and the simpler xzdec.

-
-    xz: If input file cannot be removed, treat it as a warning, not error.
-    
-    Treating it as a warning (message + exit status 2) matches gzip
-    and it seems more logical as at that point the output file has
-    already been successfully closed. When it's a warning it is
-    possible to suppress it with --no-warn.

-    Tests: Skip tests in test_*.sh if encoders and/or decoders are disabled.
-    
-    This isn't perfect as the scripts can still fail if only
-    certain filters are disabled. This is still an improvement
-    as now "make check" has better behavior when all encoders
-    or decoders are disabled.
-    
-    Grepping ../config.h is simple and fairly clean but it only
-    works if config.h was created. CMake builds don't create
-    config.h but they don't use these test scripts either.
-    
-    Thanks to Sebastian Andrzej Siewior for reporting the problem.
-    Thanks to Jia Tan for the original patch which grepped xz
-    error messages instead of config.h.

-    liblzma: Fix copying of check type statistics in lzma_index_cat().
-    
-    The check type of the last Stream in dest was never copied to
-    dest->checks (the code tried to copy it but it was done too late).
-    This meant that the value returned by lzma_index_checks() would
-    only include the check type of the last Stream when multiple
-    lzma_indexes had been concatenated.
-    
-    In xz --list this meant that the summary would only list the
-    check type of the last Stream, so in this sense this was only
-    a visual bug. However, it's possible that some applications
-    use this information for purposes other than merely showing
-    it to the users in an informational message. I'm not aware of
-    such applications though and it's quite possible that such
-    applications don't exist.
-    
-    Regular streamed decompression in xz or any other application
-    doesn't use lzma_index_cat() and so this bug cannot affect them.

-    
-    test_files.sh now runs xz -l for bad-3-index-uncomp-overflow.xz
-    because only then the previously-buggy code path gets tested.
-    Normal decompression doesn't use lzma_index_append() at all.
-    Instead, lzma_index_hash functions are used and those already
-    did the overflow check.

-    xzgrep: Fix compatibility with old shells.
-    
-    Running the current xzgrep on Slackware 10.1 with GNU bash 3.00.15:
-    
-        xzgrep: line 231: syntax error near unexpected token `;;'
-    
-    On SCO OpenServer 5.0.7 with Korn Shell 93r:
-    
-        syntax error at line 231 : `;;' unexpected
-    
-    Turns out that some old shells don't like apostrophes (') inside
-    command substitutions. For example, the following fails:
-    
-        x=$(echo foo
-        # asdf'zxcv
-        echo bar)
-        printf '%s\n' "$x"
-    
-    The problem was introduced by commits
-    69d1b3fc29677af8ade8dc15dba83f0589cb63d6 (2022-03-29),
-    bd7b290f3fe4faeceb7d3497ed9bf2e6ed5e7dc5 (2022-07-18), and
-    a648978b20495b7aa4a8b029c5a810b5ad9d08ff (2022-07-19).
-    5.2.6 is the only stable release that included
-    this problem.
-    
-    Thanks to Kevin R. Bulgrien for reporting the problem
-    on SCO OpenServer 5.0.7 and for providing the fix.

-    Tests: Silence warnings about unused functions from tuktest.h.
-    
-    Warnings about unused tuktest_run_test conveniently tell which
-    test programs haven't been converted to tuktest.h yet but I
-    silenced that warning too for now anyway.
-    
-    It is fine to use __attribute__((__unused__)) even when the
-    function is actually used because the attribute only means
-    that the function might be unused.

-    liblzma: lzma_filters_copy: Keep dest[] unmodified if an error occurs.
-    
-    lzma_stream_encoder() and lzma_stream_encoder_mt() always assumed
-    this. Before this patch, failing lzma_filters_copy() could result
-    in free(invalid_pointer) or invalid memory reads in stream_encoder.c
-    or stream_encoder_mt.c.
-    
-    To trigger this, allocating memory for a filter options structure
-    has to fail. These are tiny allocations so in practice they very
-    rarely fail.
-    
-    Certain badness in the filter chain array could also make
-    lzma_filters_copy() fail but both stream_encoder.c and
-    stream_encoder_mt.c validate the filter chain before
-    trying to copy it, so the crash cannot occur this way.

-    liblzma: lzma_index_append: Add missing integer overflow check.
-    
-    The documentation in src/liblzma/api/lzma/index.h suggests that
-    both the unpadded (compressed) size and the uncompressed size
-    are checked for overflow, but only the unpadded size was checked.
-    The uncompressed check is done first since that is more likely to
-    occur than the unpadded or index field size overflows.

-    The previous commit split liblzma.map into liblzma_linux.map and

-    
-    common_w32res.rc dependency was listed under Linux/FreeBSD while

-    liblzma: Vaccinate against an ill patch from RHEL/CentOS 7.
-    
-    RHEL/CentOS 7 shipped with 5.1.2alpha, including the threaded
-    encoder that is behind #ifdef LZMA_UNSTABLE in the API headers.
-    In 5.1.2alpha these symbols are under XZ_5.1.2alpha in liblzma.map.
-    API/ABI compatibility tracking isn't done between development
-    releases so newer releases didn't have XZ_5.1.2alpha anymore.
-    
-    Later RHEL/CentOS 7 updated xz to 5.2.2 but they wanted to keep
-    the exported symbols compatible with 5.1.2alpha. After checking
-    the ABI changes it turned out that >= 5.2.0 ABI is backward
-    compatible with the threaded encoder functions from 5.1.2alpha
-    (but not vice versa as fixes and extensions to these functions
-    were made between 5.1.2alpha and 5.2.0).
-    
-    In RHEL/CentOS 7, XZ Utils 5.2.2 was patched with
-    xz-5.2.2-compat-libs.patch to modify liblzma.map:
-    
-      - XZ_5.1.2alpha was added with lzma_stream_encoder_mt and
-        lzma_stream_encoder_mt_memusage. This matched XZ Utils 5.1.2alpha.
-    
-      - XZ_5.2 was replaced with XZ_5.2.2. It is clear that this was
-        an error; the intention was to keep using XZ_5.2 (XZ_5.2.2
-        has never been used in XZ Utils). So XZ_5.2.2 lists all
-        symbols that were listed under XZ_5.2 before the patch.
-        lzma_stream_encoder_mt and _mt_memusage are included too so
-        they are listed both here and under XZ_5.1.2alpha.
-    
-    The patch didn't add any __asm__(".symver ...") lines to the .c
-    files. Thus the resulting liblzma.so exports the threaded encoder
-    functions under XZ_5.1.2alpha only. Listing the two functions
-    also under XZ_5.2.2 in liblzma.map has no effect without
-    matching .symver lines.
-    
-    The lack of XZ_5.2 in RHEL/CentOS 7 means that binaries linked
-    against unpatched XZ Utils 5.2.x won't run on RHEL/CentOS 7.
-    This is unfortunate but this alone isn't too bad as the problem
-    is contained within RHEL/CentOS 7 and doesn't affect users
-    of other distributions. It could also be fixed internally in
-    RHEL/CentOS 7.
-    
-    The second problem is more serious: In XZ Utils 5.2.2 the API
-    headers don't have #ifdef LZMA_UNSTABLE for obvious reasons.
-    This is true in RHEL/CentOS 7 version too. Thus now programs
-    using new APIs can be compiled without an extra #define. However,
-    the programs end up depending on symbol version XZ_5.1.2alpha
-    (and possibly also XZ_5.2.2) instead of XZ_5.2 as they would
-    with an unpatched XZ Utils 5.2.2. This means that such binaries
-    won't run on other distributions shipping XZ Utils >= 5.2.0 as
-    they don't provide XZ_5.1.2alpha or XZ_5.2.2; they only provide
-    XZ_5.2 (and XZ_5.0). (This includes RHEL/CentOS 8 as the patch
-    luckily isn't included there anymore with XZ Utils 5.2.4.)
-    
-    Binaries built by RHEL/CentOS 7 users get distributed and then
-    people wonder why they don't run on some other distribution.
-    Seems that people have found out about the patch and been copying
-    it to some build scripts, seemingly curing the symptoms but
-    actually spreading the illness further and outside RHEL/CentOS 7.
-    
-    The ill patch seems to be from late 2016 (RHEL 7.3) and in 2017 it
-    had spread at least to EasyBuild. I heard about the events only
-    recently. :-(
-    
-    This commit splits liblzma.map into two versions: one for
-    GNU/Linux and another for other OSes that can use symbol versioning
-    (FreeBSD, Solaris, maybe others). The Linux-specific file and the
-    matching additions to .c files add full compatibility with binaries
-    that have been built against a RHEL/CentOS-patched liblzma. Builds
-    for OSes other than GNU/Linux won't get the vaccine as they should
-    be immune to the problem (I really hope that no build script uses
-    the RHEL/CentOS 7 patch outside GNU/Linux).
-    
-    The RHEL/CentOS compatibility symbols XZ_5.1.2alpha and XZ_5.2.2
-    are intentionally put *after* XZ_5.2 in liblzma_linux.map. This way
-    if one forgets to #define HAVE_SYMBOL_VERSIONS_LINUX when building,
-    the resulting liblzma.so.5 will have lzma_stream_encoder_mt@@XZ_5.2
-    since XZ_5.2 {...} is the first one that lists that function.
-    Without HAVE_SYMBOL_VERSIONS_LINUX @XZ_5.1.2alpha and @XZ_5.2.2
-    will be missing but that's still a minor problem compared to
-    only having lzma_stream_encoder_mt@@XZ_5.1.2alpha!
-    
-    The "local: *;" line was moved to XZ_5.0 so that it doesn't need
-    to be moved around. It doesn't matter where it is put.
-    
-    Having two similar liblzma_*.map files is a bit silly as it is,
-    at least for now, easily possible to generate the generic one
-    from the Linux-specific file. But that adds extra steps and
-    increases the risk of mistakes when supporting more than one
-    build system. So I rather maintain two files in parallel and let
-    validate_map.sh check that they are in sync when "make mydist"
-    is run.
-    
-    This adds .symver lines for lzma_stream_encoder_mt@XZ_5.2.2 and
-    lzma_stream_encoder_mt_memusage@XZ_5.2.2 even though these
-    weren't exported by RHEL/CentOS 7 (only @@XZ_5.1.2alpha was
-    for these two). I added these anyway because someone might
-    misunderstand the RHEL/CentOS 7 patch and think that @XZ_5.2.2
-    (@@XZ_5.2.2) versions were exported too.
-    
-    At glance one could suggest using __typeof__ to copy the function
-    prototypes when making aliases. However, this doesn't work trivially
-    because __typeof__ won't copy attributes (lzma_nothrow, lzma_pure)
-    and it won't change symbol visibility from hidden to default (done
-    by LZMA_API()). Attributes could be copied with __copy__ attribute
-    but that needs GCC 9 and a fallback method would be needed anyway.
-    
-    This uses __symver__ attribute with GCC >= 10 and
-    __asm__(".symver ...") with everything else. The attribute method
-    is required for LTO (-flto) support with GCC. Using -flto with
-    GCC older than 10 is now broken on GNU/Linux and will not be fixed
-    (can silently result in a broken liblzma build that has dangerously
-    incorrect symbol versions). LTO builds with Clang seem to work
-    with the traditional __asm__(".symver ...") method.
-    
-    Thanks to Boud Roukema for reporting the problem and discussing
-    the details and testing the fix.

-    Translations: Rebuild cs.po to avoid incorrect fuzzy strings.
-    
-    "make dist" updates the .po files and the fuzzy strings would

-    Windows: Fix broken liblzma.dll build with Visual Studio project files.
-    
-    The bug was introduced in 352ba2d69af2136bc814aa1df1a132559d445616
-    "Windows: Fix building of resource files when config.h isn't used."
-    
-    That commit fixed liblzma.dll build with CMake while keeping it
-    working with Autotools on Windows but the VS project files were
-    forgotten.
-    
-    I haven't tested these changes.
-    
-    Thanks to Olivier B. for reporting the bug and for the initial patch.

-    xzgrep: Improve error handling, especially signals.
-    
-    xzgrep wouldn't exit on SIGPIPE or SIGQUIT when it clearly
-    should have. It's quite possible that it's not perfect still
-    but at least it's much better.
-    
-    If multiple exit statuses compete, now it tries to pick
-    the largest of value.
-    
-    Some comments were added.
-    
-    The exit status handling of signals is still broken if the shell
-    uses values larger than 255 in $? to indicate that a process
-    died due to a signal ***and*** their "exit" command doesn't take
-    this into account. This seems to work well with the ksh and yash
-    versions I tried. However, there is a report in gzip/zgrep that
-    OpenSolaris 5.11 (not 5.10) has a problem with "exit" truncating
-    the argument to 8 bits:
-    
-        https://debbugs.gnu.org/cgi/bugreport.cgi?bug=22900#25
-    
-    Such a bug would break xzgrep but I didn't add a workaround
-    at least for now. 5.11 is old and I don't know if the problem
-    exists in modern descendants, or if the problem exists in other
-    ksh implementations in use.

-Author: Lasse Collin <lasse.collin@tukaani.org>
-Date:   2022-07-18 21:52:31 +0300
-
-    xzgrep: Use grep -H --label when available (GNU, *BSDs).
-    
-    It avoids the use of sed for prefixing filenames to output lines.
-    Using sed for that is slower and prone to security bugs so now
-    the sed method is only used as a fallback.
-    
-    This also fixes an actual bug: When grepping a binary file,
-    GNU grep nowadays prints its diagnostics to stderr instead of
-    stdout and thus the sed-method for prefixing the filename doesn't
-    work. So with this commit grepping binary files gives reasonable
-    output with GNU grep now.
-    
-    This was inspired by zgrep but the implementation is different.

-Author: Lasse Collin <lasse.collin@tukaani.org>
-Date:   2022-07-17 21:36:25 +0300
-
-    xzgrep: Add more LC_ALL=C to avoid bugs with multibyte characters.
-    
-    Also replace one use of expr with printf.
-    
-    The rationale for LC_ALL=C was already mentioned in
-    69d1b3fc29677af8ade8dc15dba83f0589cb63d6 that fixed a security
-    issue. However, unrelated uses weren't changed in that commit yet.
-    
-    POSIX says that with sed and such tools one should use LC_ALL=C
-    to ensure predictable behavior when strings contain byte sequences
-    that aren't valid multibyte characters in the current locale. See
-    under "Application usage" in here:
-    
-    https://pubs.opengroup.org/onlinepubs/9699919799/utilities/sed.html
-    
-    With GNU sed invalid multibyte strings would work without this;
-    it's documented in its Texinfo manual. Some other implementations
-    aren't so forgiving.

-Date:   2022-07-17 20:55:16 +0300
-
-    xzgrep: Fix parsing of certain options.
-    
-    Fix handling of "xzgrep -25 foo" (in GNU grep "grep -25 foo" is
-    an alias for "grep -C25 foo"). xzgrep would treat "foo" as filename
-    instead of as a pattern. This bug was fixed in zgrep in gzip in 2012.
-    
-    Add -E, -F, -G, and -P to the "no argument required" list.
-    
-    Add -X to "argument required" list. It is an
-    intentionally-undocumented GNU grep option so this isn't
-    an important option for xzgrep but it seems that other grep
-    implementations (well, those that I checked) don't support -X
-    so I hope this change is an improvement still.
-    
-    grep -d (grep --directories=ACTION) requires an argument. In
-    contrast to zgrep, I kept -d in the "no argument required" list
-    because it's not supported in xzgrep (or zgrep). This way
-    "xzgrep -d" gives an error about option being unsupported instead
-    of telling that it requires an argument. Both zgrep and xzgrep
-    tell that it's unsupported if an argument is specified.
-    
-    Add comments.

-    liblzma: Add optional autodetection of LZMA end marker.
-    
-    Turns out that this is needed for .lzma files as the spec in
-    LZMA SDK says that end marker may be present even if the size
-    is stored in the header. Such files are rare but exist in the
-    real world. The code in liblzma is so old that the spec didn't
-    exist in LZMA SDK back then and I had understood that such
-    files weren't possible (the lzma tool in LZMA SDK didn't
-    create such files).
-    
-    This modifies the internal API so that LZMA decoder can be told
-    if EOPM is allowed even when the uncompressed size is known.
-    It's allowed with .lzma and not with other uses.
-    
-    Thanks to Karl Beldan for reporting the problem.

-    Build: Enable Automake's parallel test harness.
-    
-    It has been the default for quite some time already and
-    the old serial harness isn't discouraged. The downside is
-    that with parallel tests one cannot print progress info or
-    other diagnostics to the terminal; all output from the tests
-    will be in the log files only. But now that the compression
-    tests are separated the parallel tests will speed things up.

-    xz: Add a default soft memory usage limit for --threads=0.
-    
-    This is a soft limit in sense that it only affects the number of
-    threads. It never makes xz fail and it never makes xz change
-    settings that would affect the compressed output.
-    
-    The idea is to make -T0 have more reasonable behavior when
-    the system has very many cores or when a memory-hungry
-    compression options are used. This also helps with 32-bit xz,
-    preventing it from running out of address space.
-    
-    The downside of this commit is that now the number of threads
-    might become too low compared to what the user expected. I
-    hope this to be an acceptable compromise as the old behavior
-    has been a source of well-argued complaints for a long time.

-    xz: Make -T0 use multithreaded mode on single-core systems.
-    
-    The main problem withi the old behavior is that the compressed
-    output is different on single-core systems vs. multicore systems.
-    This commit fixes it by making -T0 one thread in multithreaded mode
-    on single-core systems.
-    
-    The downside of this is that it uses more memory. However, if
-    --memlimit-compress is used, xz can (thanks to the previous commit)
-    drop to the single-threaded mode still.

-    xz: Changes to --memlimit-compress and --no-adjust.
-    
-    In single-threaded mode, --memlimit-compress can make xz scale down
-    the LZMA2 dictionary size to meet the memory usage limit. This
-    obviously affects the compressed output. However, if xz was in
-    threaded mode, --memlimit-compress could make xz reduce the number
-    of threads but it wouldn't make xz switch from multithreaded mode
-    to single-threaded mode or scale down the LZMA2 dictionary size.
-    This seemed illogical and there was even a "FIXME?" about it.
-    
-    Now --memlimit-compress can make xz switch to single-threaded
-    mode if one thread in multithreaded mode uses too much memory.
-    If memory usage is still too high, then the LZMA2 dictionary
-    size can be scaled down too.
-    
-    The option --no-adjust was also changed so that it no longer
-    prevents xz from scaling down the number of threads as that
-    doesn't affect compressed output (only performance). After
-    this commit --no-adjust only prevents adjustments that affect
-    compressed output, that is, with --no-adjust xz won't switch
-    from multithreaded mode to single-threaded mode and won't
-    scale down the LZMA2 dictionary size.
-    
-    The man page wasn't updated yet.

-    xz: Add --memlimit-mt-decompress along with a default limit value.
-    
-    --memlimit-mt-decompress allows specifying the limit for
-    multithreaded decompression. This matches memlimit_threading in
-    liblzma. This limit can only affect the number of threads being
-    used; it will never prevent xz from decompressing a file. The
-    old --memlimit-decompress option is still used at the same time.
-    
-    If the value of --memlimit-decompress (the default value or
-    one specified by the user) is less than the value of
-    --memlimit-mt-decompress , then --memlimit-mt-decompress is
-    reduced to match --memlimit-decompress.
-    
-    Man page wasn't updated yet.

-    liblzma: Add a new flag LZMA_FAIL_FAST for threaded decoder.
-    
-    In most cases if the input file is corrupt the application won't
-    care about the uncompressed content at all. With this new flag
-    the threaded decoder will return an error as soon as any thread
-    has detected an error; it won't wait to copy out the data before
-    the location of the error.
-    
-    I don't plan to use this in xz to keep the behavior consistent
-    between single-threaded and multi-threaded modes.

-
-    liblzma: Threaded decoder: Support zpipe.c-style decoding loop.
-    
-    This makes it possible to call lzma_code() in a loop that only
-    reads new input when lzma_code() didn't fill the output buffer
-    completely. That isn't the calling style suggested by the
-    liblzma example program 02_decompress.c so perhaps the usefulness
-    of this feature is limited.
-    
-    Also, it is possible to write such a loop so that it works
-    with the single-threaded decoder but not with the threaded
-    decoder even after this commit, or so that it works only if
-    lzma_mt.timeout = 0.
-    
-    The zlib tutorial <https://zlib.net/zlib_how.html> is a well-known
-    example of a loop where more input is read only when output isn't
-    full. Porting this as is to liblzma would work with the
-    single-threaded decoder (if LZMA_CONCATENATED isn't used) but it
-    wouldn't work with threaded decoder even after this commit because
-    the loop assumes that no more output is possible when it cannot
-    read more input ("if (strm.avail_in == 0) break;"). This cannot
-    be fixed at liblzma side; the loop has to be modified at least
-    a little.
-    
-    I'm adding this in any case because the actual code is simple
-    and short and should have no harmful side-effects in other
-    situations.

-    xzgrep: Fix escaping of malicious filenames (ZDI-CAN-16587).
-    
-    Malicious filenames can make xzgrep to write to arbitrary files
-    or (with a GNU sed extension) lead to arbitrary code execution.
-    
-    xzgrep from XZ Utils versions up to and including 5.2.5 are
-    affected. 5.3.1alpha and 5.3.2alpha are affected as well.
-    This patch works for all of them.
-    
-    This bug was inherited from gzip's zgrep. gzip 1.12 includes
-    a fix for zgrep.
-    
-    The issue with the old sed script is that with multiple newlines,
-    the N-command will read the second line of input, then the
-    s-commands will be skipped because it's not the end of the
-    file yet, then a new sed cycle starts and the pattern space
-    is printed and emptied. So only the last line or two get escaped.
-    
-    One way to fix this would be to read all lines into the pattern
-    space first. However, the included fix is even simpler: All lines
-    except the last line get a backslash appended at the end. To ensure
-    that shell command substitution doesn't eat a possible trailing
-    newline, a colon is appended to the filename before escaping.
-    The colon is later used to separate the filename from the grep
-    output so it is fine to add it here instead of a few lines later.
-    
-    The old code also wasn't POSIX compliant as it used \n in the
-    replacement section of the s-command. Using \<newline> is the
-    POSIX compatible method.
-    
-    LC_ALL=C was added to the two critical sed commands. POSIX sed
-    manual recommends it when using sed to manipulate pathnames
-    because in other locales invalid multibyte sequences might
-    cause issues with some sed implementations. In case of GNU sed,
-    these particular sed scripts wouldn't have such problems but some
-    other scripts could have, see:
-    
-        info '(sed)Locale Considerations'
-    
-    This vulnerability was discovered by:
-    cleemy desu wayo working with Trend Micro Zero Day Initiative
-    
-    Thanks to Jim Meyering and Paul Eggert discussing the different
-    ways to fix this and for coordinating the patch release schedule
-    with gzip.

-    liblzma: Fix a deadlock in threaded decoder.
-    
-    If a worker thread has consumed all input so far and it's
-    waiting on thr->cond and then the main thread enables
-    partial update for that thread, the code used to deadlock.
-    This commit allows one dummy decoding pass to occur in this
-    situation which then also does the partial update.
-    
-    As part of the fix, this moves thr->progress_* updates to
-    avoid the second thr->mutex locking.
-    
-    Thanks to Jia Tan for finding, debugging, and reporting the bug.

-
-    xz: Add initial support for threaded decompression.
-    
-    If threading support is enabled at build time, this will
-    use lzma_stream_decoder_mt() even for single-threaded mode.
-    With memlimit_threading=0 the behavior should be identical.
-    
-    This needs some work like adding --memlimit-threading=LIMIT.
-    
-    The original patch from Sebastian Andrzej Siewior included
-    a method to get currently available RAM on Linux. It might
-    be one way to go but as it is Linux-only, the available-RAM
-    approach needs work for portability or using a fallback method
-    on other OSes.
-    
-    The man page wasn't updated yet.

-    
-    Track both the total amount of memory allocated and the amount of

-    
-    In lzma_outbuf, allow storing the current input position that
-    matches the current output position. This way the main thread
-    can notice when no more output is possible without first providing
-    more input.
-

-    liblzma: Make Block decoder catch certain types of errors better.
-    
-    Now it limits the input and output buffer sizes that are
-    passed to a raw decoder. This way there's no need to check
-    if the sizes can grow too big or overflow when updating
-    Compressed Size and Uncompressed Size counts. This also means
-    that a corrupt file cannot cause the raw decoder to process
-    useless extra input or output that would exceed the size info
-    in Block Header (and thus cause LZMA_DATA_ERROR anyway).
-    
-    More importantly, now the size information is verified more
-    carefully in case raw decoder returns LZMA_OK. This doesn't
-    really matter with the current single-threaded .xz decoder
-    as the errors would be detected slightly later anyway. But
-    this helps avoiding corner cases in the upcoming threaded
-    decompressor, and it might help other Block decoder uses
-    outside liblzma too.
-    
-    The test files bad-1-lzma2-{9,10,11}.xz test these conditions.
-    With the single-threaded .xz decoder the only difference is
-    that LZMA_DATA_ERROR is detected in a difference place now.

-    OpenBSD does not allow to change the group of a file if the user
-    does not belong to this group.  In contrast to Linux, OpenBSD also
-    fails if the new group is the same as the old one.  Do not call

-    Reduce maximum possible memory limit on MIPS32
-    
-    Due to architectural limitations, address space available to a single
-    userspace process on MIPS32 is limited to 2 GiB, not 4, even on systems
-    that have more physical RAM -- e.g. 64-bit systems with 32-bit
-    userspace, or systems that use XPA (an extension similar to x86's PAE).
-    
-    So, for MIPS32, we have to impose stronger memory limits. I've chosen
-    2000MiB to give the process some headroom.

-Author: Lasse Collin <lasse.collin@tukaani.org>
-Date:   2021-01-30 18:36:04 +0200
-
-    CMake: Try to improve compatibility with the FindLibLZMA module.
-    
-    The naming conflict with FindLibLZMA module gets worse.
-    Not avoiding it in the first place was stupid.
-    
-    Normally find_package(LibLZMA) will use the module and
-    find_package(liblzma 5.2.5 REQUIRED CONFIG) will use the config
-    file even with a case insensitive file system. However, if
-    CMAKE_FIND_PACKAGE_PREFER_CONFIG is TRUE and the file system
-    is case insensitive, find_package(LibLZMA) will find our liblzma
-    config file instead of using FindLibLZMA module.
-    
-    One big problem with this is that FindLibLZMA uses
-    LibLZMA::LibLZMA and we use liblzma::liblzma as the target
-    name. With target names CMake happens to be case sensitive.
-    To workaround this, this commit adds
-    
-        add_library(LibLZMA::LibLZMA ALIAS liblzma::liblzma)
-    
-    to the config file. Then both spellings work.
-    
-    To make the behavior consistent between case sensitive and
-    insensitive file systems, the config and related files are
-    renamed from liblzmaConfig.cmake to liblzma-config.cmake style.
-    With this style CMake looks for lowercase version of the package
-    name so find_package(LiBLzmA 5.2.5 REQUIRED CONFIG) will work
-    to find our config file.
-    
-    There are other differences between our config file and
-    FindLibLZMA so it's still possible that things break for
-    reasons other than the spelling of the target name. Hopefully
-    those situations aren't too common.
-    
-    When the config file is available, it should always give as good or
-    better results as FindLibLZMA so this commit doesn't affect the
-    recommendation to use find_package(liblzma 5.2.5 REQUIRED CONFIG)
-    which explicitly avoids FindLibLZMA.
-    
-    Thanks to Markus Rickert.

-    liblzma: Add EROFS LZMA encoder and decoder.
-    
-    Right now this is just a planned extra-compact format for use
-    in the EROFS file system in Linux. At this point it's possible
-    that the format will either change or be abandoned and removed
-    completely.
-    
-    The special thing about the encoder is that it uses the
-    output-size-limited encoding added in the previous commit.
-    EROFS uses fixed-sized blocks (e.g. 4 KiB) to hold compressed
-    data so the compressors must be able to create valid streams
-    that fill the given block size.

-
-    liblzma: Add rough support for output-size-limited encoding in LZMA1.
-    
-    With this it is possible to encode LZMA1 data without EOPM so that
-    the encoder will encode as much input as it can without exceeding
-    the specified output size limit. The resulting LZMA1 stream will
-    be a normal LZMA1 stream without EOPM. The actual uncompressed size
-    will be available to the caller via the uncomp_size pointer.
-    
-    One missing thing is that the LZMA layer doesn't inform the LZ layer
-    when the encoding is finished and thus the LZ may read more input
-    when it won't be used. However, this doesn't matter if encoding is
-    done with a single call (which is the planned use case for now).
-    For proper multi-call encoding this should be improved.
-    
-    This commit only adds the functionality for internal use.
-    Nothing uses it yet.

-    xz: Make --keep accept symlinks, hardlinks, and setuid/setgid/sticky.
-    
-    Previously this required using --force but that has other
-    effects too which might be undesirable. Changing the behavior
-    of --keep has a small risk of breaking existing scripts but
-    since this is a fairly special corner case I expect the
-    likehood of breakage to be low enough.
-    
-    I think the new behavior is more logical. The only reason for
-    the old behavior was to be consistent with gzip and bzip2.

-    Scripts: Fix exit status of xzgrep.
-    
-    Omit the -q option from xz, gzip, and bzip2. With xz this shouldn't
-    matter. With gzip it's important because -q makes gzip replace SIGPIPE
-    with exit status 2. With bzip2 it's important because with -q bzip2
-    is completely silent if input is corrupt while other decompressors
-    still give an error message.
-    
-    Avoiding exit status 2 from gzip is important because bzip2 uses
-    exit status 2 to indicate corrupt input. Before this commit xzgrep
-    didn't recognize corrupt .bz2 files because xzgrep was treating
-    exit status 2 as SIGPIPE for gzip compatibility.
-    
-    zstd still needs -q because otherwise it is noisy in normal
-    operation.
-    
-    The code to detect real SIGPIPE didn't check if the exit status
-    was due to a signal (>= 128) and so could ignore some other exit
-    status too.

-    Scripts: Fix exit status of xzdiff/xzcmp.
-    
-    This is a minor fix since this affects only the situation when
-    the files differ and the exit status is something else than 0.
-    In such case there could be SIGPIPE from a decompression tool
-    and that would result in exit status of 2 from xzdiff/xzcmp
-    while the correct behavior would be to return 1 or whatever
-    else diff or cmp may have returned.
-    
-    This commit omits the -q option from xz/gzip/bzip2/lzop arguments.
-    I'm not sure why the -q was used in the first place, perhaps it
-    hides warnings in some situation that I cannot see at the moment.
-    Hopefully the removal won't introduce a new bug.
-    
-    With gzip the -q option was harmful because it made gzip return 2
-    instead of >= 128 with SIGPIPE. Ignoring exit status 2 (warning
-    from gzip) isn't practical because bzip2 uses exit status 2 to
-    indicate corrupt input file. It's better if SIGPIPE results in
-    exit status >= 128.
-    
-    With bzip2 the removal of -q seems to be good because with -q
-    it prints nothing if input is corrupt. The other tools aren't
-    silent in this situation even with -q. On the other hand, if
-    zstd support is added, it will need -q since otherwise it's
-    noisy in normal situations.
-    
-    Thanks to Étienne Mollier and Sebastian Andrzej Siewior.

-    liblzma: Make lzma_outq usable for threaded decompression too.
-    
-    Before this commit all output queue buffers were allocated as
-    a single big allocation. Now each buffer is allocated separately
-    when needed. Used buffers are cached to avoid reallocation
-    overhead but the cache will keep only one buffer size at a time.
-    This should make things work OK in the decompression where most
-    of the time the buffer sizes will be the same but with some less
-    common files the buffer sizes may vary.
-    
-    While this should work fine, it's still a bit preliminary
-    and may even get reverted if it turns out to be useless for
-    decompression.

-    Build: Fix bugs in the CMake files.
-    
-    Seems that the phrase "add more quotes" from sh/bash scripting
-    applies to CMake as well. E.g. passing an unquoted list ${FOO}
-    to a function that expects one argument results in only the
-    first element of the list being passed as an argument and
-    the rest get ignored. Adding quotes helps ("${FOO}").
-    
-    list(INSERT ...) is weird. Inserting an empty string to an empty
-    variable results in empty list, but inserting it to a non-empty
-    variable does insert an empty element to the list.
-    
-    Since INSERT requires at least one element,
-    "${CMAKE_THREAD_LIBS_INIT}" needs to be quoted in CMakeLists.txt.
-    It might result in an empty element in the list. It seems to not
-    matter as empty elements consistently get ignored in that variable.
-    In fact, calling cmake_check_push_state() and cmake_check_pop_state()
-    will strip the empty elements from CMAKE_REQUIRED_LIBRARIES!
-    
-    In addition to quoting fixes, this fixes checks for the cache
-    variables in tuklib_cpucores.cmake and tuklib_physmem.cmake.
-    
-    Thanks to Martin Matuška for testing and reporting the problems.
-    These fixes aren't tested yet but hopefully they soon will be.

-    Build: Add very limited experimental CMake support.
-    
-    This does *NOT* replace the Autotools-based build system in
-    the foreseeable future. See the comment in the beginning
-    of CMakeLists.txt.
-    
-    So far this has been tested only on GNU/Linux but I commit
-    it anyway to make it easier for others to test. Since I
-    haven't played much with CMake before, it's likely that
-    there are things that have been done in a silly or wrong
-    way and need to be fixed.

-
-    Build: Add support for translated man pages using po4a.
-    
-    The dependency on po4a is optional. It's never required to install
-    the translated man pages when xz is built from a release tarball.
-    If po4a is missing when building from xz.git, the translated man
-    pages won't be generated but otherwise the build will work normally.
-    
-    The translations are only updated automatically by autogen.sh and
-    by "make mydist". This makes it easy to keep po4a as an optional
-    dependency and ensures that I won't forget to put updated
-    translations to a release tarball.
-    
-    The translated man pages aren't installed if --disable-nls is used.
-    
-    The installation of translated man pages abuses Automake internals
-    by calling "install-man" with redefined dist_man_MANS and man_MANS.
-    This makes the hairy script code slightly less hairy. If it breaks
-    some day, this code needs to be fixed; don't blame Automake developers.
-    
-    Also, this adds more quotes to the existing shell script code in
-    the Makefile.am "-hook"s.

-    I don't know if the problem is in gnulib's gl_POSIX_SHELL macro
-    or if xzgrep does something that isn't in POSIX. The workaround
-    adds a special case for Solaris: if /usr/xpg4/bin/sh exists and
-    gl_cv_posix_shell wasn't overriden on the configure command line,
-    use that shell for xzgrep and other scripts. That shell is known
-    to work and exists on most Solaris systems.

-    xz: Limit --memlimit-compress to at most 4020 MiB for 32-bit xz.
-    
-    See the code comment for reasoning. It's far from perfect but
-    hopefully good enough for certain cases while hopefully doing
-    nothing bad in other situations.
-    
-    At presets -5 ... -9, 4020 MiB vs. 4096 MiB makes no difference
-    on how xz scales down the number of threads.
-    
-    The limit has to be a few MiB below 4096 MiB because otherwise
-    things like "xz --lzma2=dict=500MiB" won't scale down the dict
-    size enough and xz cannot allocate enough memory. With
-    "ulimit -v $((4096 * 1024))" on x86-64, the limit in xz had
-    to be no more than 4085 MiB. Some safety margin is good though.
-    
-    This is hack but it should be useful when running 32-bit xz on
-    a 64-bit kernel that gives full 4 GiB address space to xz.
-    Hopefully this is enough to solve this:
-    
-    https://bugzilla.redhat.com/show_bug.cgi?id=1196786
-    
-    FreeBSD has a patch that limits the result in tuklib_physmem()
-    to SIZE_MAX on 32-bit systems. While I think it's not the way
-    to do it, the results on --memlimit-compress have been good. This
-    commit should achieve practically identical results for compression
-    while leaving decompression and tuklib_physmem() and thus
-    lzma_physmem() unaffected.

-    xz: Set the --flush-timeout deadline when the first input byte arrives.
-    
-    xz --flush-timeout=2000, old version:
-    
-      1. xz is started. The next flush will happen after two seconds.
-      2. No input for one second.
-      3. A burst of a few kilobytes of input.
-      4. No input for one second.
-      5. Two seconds have passed and flushing starts.
-    
-    The first second counted towards the flush-timeout even though
-    there was no pending data. This can cause flushing to occur more
-    often than needed.
-    
-    xz --flush-timeout=2000, after this commit:
-    
-      1. xz is started.
-      2. No input for one second.
-      3. A burst of a few kilobytes of input. The next flush will
-         happen after two seconds counted from the time when the
-         first bytes of the burst were read.
-      4. No input for one second.
-      5. No input for another second.
-      6. Two seconds have passed and flushing starts.

-    flush and thus would just waste CPU time. The fix disables the
-    timeout when no input has been seen since the previous flush.

-
-    Rename read32ne to aligned_read32ne, and similarly for the others.
-    
-    Using the aligned methods requires more care to ensure that
-    the address really is aligned, so it's nicer if the aligned
-    methods are prefixed. The next commit will remove the unaligned_
-    prefix from the unaligned methods which in liblzma are used in
-    more places than the aligned ones.

-Date:   2019-12-31 00:18:24 +0200
-
-    Revise tuklib_integer.h and .m4.
-    
-    Add a configure option --enable-unsafe-type-punning to get the
-    old non-conforming memory access methods. It can be useful with
-    old compilers or in some other less typical situations but
-    shouldn't normally be used.
-    
-    Omit the packed struct trick for unaligned access. While it's
-    best in some cases, this is simpler. If the memcpy trick doesn't
-    work, one can request unsafe type punning from configure.
-    
-    Because CRC32/CRC64 code needs fast aligned reads, if no very
-    safe way to do it is found, type punning is used as a fallback.
-    This sucks but since it currently works in practice, it seems to
-    be the least bad option. It's never needed with GCC >= 4.7 or
-    Clang >= 3.6 since these support __builtin_assume_aligned and
-    thus fast aligned access can be done with the memcpy trick.
-    
-    Other things:
-      - Support GCC/Clang __builtin_bswapXX
-      - Cleaner bswap fallback macros
-      - Minor cleanups

-    Scripts: Put /usr/xpg4/bin to the beginning of PATH on Solaris.

-    This adds a configure option --enable-path-for-scripts=PREFIX

-    to make POSIX grep and others available. The Solaris case had
-    been documented in INSTALL with a manual fix but it's better

-    Add LZMA_RET_INTERNAL1..8 to lzma_ret and use one for LZMA_TIMED_OUT.
-    
-    LZMA_TIMED_OUT is *internally* used as a value for lzma_ret
-    enumeration. Previously it was #defined to 32 and cast to lzma_ret.
-    That way it wasn't visible in the public API, but this was hackish.
-    
-    Now the public API has eight LZMA_RET_INTERNALx members and
-    LZMA_TIMED_OUT is #defined to LZMA_RET_INTERNAL1. This way
-    the code is cleaner overall although the public API has a few
-    extra mysterious enum members.

-    Use a temporary variable instead of e.g.
-    conv32le(unaligned_read32ne(buf)) because the macro can
-    evaluate its argument multiple times.

-    tuklib_integer: Improve unaligned memory access.
-    
-    Now memcpy() or GNU C packed structs for unaligned access instead
-    of type punning. See the comment in this commit for details.
-    
-    Avoiding type punning with unaligned access is needed to
-    silence gcc -fsanitize=undefined.
-    
-    New functions: unaliged_readXXne and unaligned_writeXXne where
-    XX is 16, 32, or 64.

-    liblzma: Avoid memcpy(NULL, foo, 0) because it is undefined behavior.
-    
-    I should have always known this but I didn't. Here is an example
-    as a reminder to myself:
-    
-        int mycopy(void *dest, void *src, size_t n)
-        {
-            memcpy(dest, src, n);
-            return dest == NULL;
-        }
-    
-    In the example, a compiler may assume that dest != NULL because
-    passing NULL to memcpy() would be undefined behavior. Testing
-    with GCC 8.2.1, mycopy(NULL, NULL, 0) returns 1 with -O0 and -O1.
-    With -O2 the return value is 0 because the compiler infers that
-    dest cannot be NULL because it was already used with memcpy()
-    and thus the test for NULL gets optimized out.
-    
-    In liblzma, if a null-pointer was passed to memcpy(), there were
-    no checks for NULL *after* the memcpy() call, so I cautiously
-    suspect that it shouldn't have caused bad behavior in practice,
-    but it's hard to be sure, and the problematic cases had to be
-    fixed anyway.
-    
-    Thanks to Jeffrey Walton.

-    Windows/VS2017: Omit WindowsTargetPlatformVersion from project files.
-    
-    I understood that if a WTPV is specified, it's often wrong
-    because different VS installations have different SDK version
-    installed. Omitting the WTPV tag makes VS2017 default to
-    Windows SDK 8.1 which often is also missing, so in any case
-    people may need to specify the WTPV before building. But some
-    day in the future a missing WTPV tag will start to default to
-    the latest installed SDK which sounds reasonable:
-

-    Thanks to "dom".

-    xz: Fix a crash in progress indicator when in passthru mode.
-    
-    "xz -dcfv not_an_xz_file" crashed (all four options are
-    required to trigger it). It caused xz to call
-    lzma_get_progress(&strm, ...) when no coder was initialized
-    in strm. In this situation strm.internal is NULL which leads
-    to a crash in lzma_get_progress().
-    
-    The bug was introduced when xz started using lzma_get_progress()
-    to get progress info for multi-threaded compression, so the
-    bug is present in versions 5.1.3alpha and higher.
-    
-    Thanks to Filip Palian <Filip.Palian@pjwstk.edu.pl> for
-    the bug report.

-    liblzma: Don't verify header CRC32s if building for fuzz testing.
-    
-    FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION is #defined when liblzma
-    is being built for fuzz testing.
-    
-    Most fuzzed inputs would normally get rejected because of incorrect
-    CRC32 and the actual header decoding code wouldn't get fuzzed.
-    Disabling CRC32 checks avoids this problem. The fuzzer program
-    must still use LZMA_IGNORE_CHECK flag to disable verification of
-    integrity checks of uncompressed data.

-    liblzma: Fix lzma_memlimit_set(strm, 0).
-    
-    The 0 got treated specially in a buggy way and as a result
-    the function did nothing. The API doc said that 0 was supposed
-    to return LZMA_PROG_ERROR but it didn't.
-    
-    Now 0 is treated as if 1 had been specified. This is done because
-    0 is already used to indicate an error from lzma_memlimit_get()
-    and lzma_memusage().
-    
-    In addition, lzma_memlimit_set() no longer checks that the new
-    limit is at least LZMA_MEMUSAGE_BASE. It's counter-productive
-    for the Index decoder and was actually needed only by the
-    auto decoder. Auto decoder has now been modified to check for
-    LZMA_MEMUSAGE_BASE.

-
-    liblzma: Fix handling of memlimit == 0 in lzma_index_decoder().
-    
-    It returned LZMA_PROG_ERROR, which was done to avoid zero as
-    the limit (because it's a special value elsewhere), but using
-    LZMA_PROG_ERROR is simply inconvenient and can cause bugs.
-    
-    The fix/workaround is to treat 0 as if it were 1 byte. It's
-    effectively the same thing. The only weird consequence is
-    that then lzma_memlimit_get() will return 1 even when 0 was
-    specified as the limit.
-    
-    This fixes a very rare corner case in xz --list where a specific
-    memory usage limit and a multi-stream file could print the
-    error message "Internal error (bug)" instead of saying that
-    the memory usage limit is too low.

-    tuklib_cpucores: Add support for sched_getaffinity().
-    
-    It's available in glibc (GNU/Linux, GNU/kFreeBSD). It's better
-    than sysconf(_SC_NPROCESSORS_ONLN) because sched_getaffinity()
-    gives the number of cores available to the process instead of
-    the total number of cores online.
-    
-    As a side effect, this commit fixes a bug on GNU/kFreeBSD where
-    configure would detect the FreeBSD-specific cpuset_getaffinity()
-    but it wouldn't actually work because on GNU/kFreeBSD it requires
-    using -lfreebsd-glue when linking. Now the glibc-specific function
-    will be used instead.
-    
-    Thanks to Sebastian Andrzej Siewior for the original patch
-    and testing.

-    liblzma: Disable external SHA-256 by default.
-    
-    This is the sane thing to do. The conflict with OpenSSL
-    on some OSes and especially that the OS-provided versions
-    can be significantly slower makes it clear that it was
-    a mistake to have the external SHA-256 support enabled by
-    default.
-    
-    Those who want it can now pass --enable-external-sha256 to
-    configure. INSTALL was updated with notes about OSes where
-    this can be a bad idea.
-    
-    The SHA-256 detection code in configure.ac had some bugs that
-    could lead to a build failure in some situations. These were
-    fixed, although it doesn't matter that much now that the
-    external SHA-256 is disabled by default.
-    
-    MINIX >= 3.2.0 uses NetBSD's libc and thus has SHA256_Init
-    in libc instead of libutil. Support for the libutil version
-    was removed.

-    Build: Avoid SHA256_Init on FreeBSD and MINIX 3.
-    
-    On FreeBSD 10 and older, SHA256_Init from libmd conflicts
-    with libcrypto from OpenSSL. The OpenSSL version has
-    different sizeof(SHA256_CTX) and it can cause weird
-    problems if wrong SHA256_Init gets used.
-    
-    Looking at the source, MINIX 3 seems to have a similar issue but
-    I'm not sure. To be safe, I disabled SHA256_Init on MINIX 3 too.
-    
-    NetBSD has SHA256_Init in libc and they had a similar problem,
-    but they already fixed it in 2009.
-    
-    Thanks to Jim Wilcoxson for the bug report that helped
-    in finding the problem.

-    liblzma: Make Valgrind happier with optimized (gcc -O2) liblzma.
-    
-    When optimizing, GCC can reorder code so that an uninitialized

-    It doesn't happen when compiled with -O0, which I tend to use
-    when running Valgrind.

-    
-    lzma_encocder_presets.c was renamed to lzma_presets.c to

-    Update German translation, mostly wrt orthography
-    
-    Provide an update of the German translation.
-    * A lot of compound words were previously written with spaces, while
-      German orthography is relatively clear in that the components
-      should not be separated.
-    * When referring to the actual process of (de)compression rather than the
-      concept, replace “(De-)Kompression” with “(De-)Komprimierung”.
-      Previously, both forms were used in this context and are now used in a
-      manner consistent with “Komprimierung” being more likely to refer to
-      a process.
-    * Consistently translate “standard input”/“output”
-    * Use “Zeichen” instead of false friend “Charakter” for “character”
-    * Insert commas around relative clauses (as required in German)
-    * Some other minor corrections
-    * Capitalize “ß” as “ẞ”
-    * Consistently start option descriptions in --help with capital letters
-    
-    Acked-By: Andre Noll <maan@tuebingen.mpg.de>

-    Fix typo in German translation.
-    
-    As pointed out by Robert Pollak, there's a typo in the German
-    translation of the compression preset option (-0 ... -9) help text.
-    "The compressor" translates to "der Komprimierer", and the genitive
-    form is "des Komprimierers". The old word makes no sense at all.

-    Revert "xz: Use pipe2() if available."
-    
-    This reverts commit 7a11c4a8e5e15f13d5fa59233b3172e65428efdd.
-    It is a problem when libc has pipe2() but the kernel is too
-    old to have pipe2() and thus pipe2() fails. In xz it's pointless
-    to have a fallback for non-functioning pipe2(); it's better to
-    avoid pipe2() completely.
-    
-    Thanks to Michael Fox for the bug report.

-    xz: Add support for sandboxing with Capsicum.
-    
-    The sandboxing is used conditionally as described in main.c.
-    This isn't optimal but it was much easier to implement than
-    a full sandboxing solution and it still covers the most common
-    use cases where xz is writing to standard output. This should
-    have practically no effect on performance even with small files
-    as fork() isn't needed.
-    
-    C and locale libraries can open files as needed. This has been
-    fine in the past, but it's a problem with things like Capsicum.
-    io_sandbox_enter() tries to ensure that various locale-related
-    files have been loaded before cap_enter() is called, but it's
-    possible that there are other similar problems which haven't
-    been seen yet.
-    
-    Currently Capsicum is available on FreeBSD 10 and later
-    and there is a port to Linux too.
-    
-    Thanks to Loganaden Velvindron for help.

-
-    Fix bugs and otherwise improve ax_check_capsicum.m4.
-    
-    AU_ALIAS was removed because the new version is incompatible
-    with the old version.
-    
-    It no longer checks for <sys/capability.h> separately.
-    It's enough to test for it as part of AC_CHECK_DECL.
-    The defines HAVE_CAPSICUM_SYS_CAPSICUM_H and
-    HAVE_CAPSICUM_SYS_CAPABILITY_H were removed as unneeded.
-    HAVE_SYS_CAPSICUM_H from AC_CHECK_HEADERS is enough.
-    
-    It no longer does a useless search for the Capsicum library
-    if the header wasn't found.
-    
-    Fixed a bug in ACTION-IF-FOUND (the first argument). Specifying
-    the argument omitted the default action but the given action
-    wasn't used instead.
-    
-    AC_DEFINE([HAVE_CAPSICUM]) is now always called when Capsicum
-    support is found. Previously it was part of the default
-    ACTION-IF-FOUND which a custom action would override. Now
-    the default action only prepends ${CAPSICUM_LIB} to LIBS.
-    
-    The documentation was updated.
-    
-    Since there as no serial number, "#serial 2" was added.

-    Fix CPU core count detection on QNX.
-    
-    It tried to use sysctl() on QNX but
-      - it broke the build because sysctl() needs -lsocket on QNX;
-      - sysctl() doesn't work for detecting the core count on QNX
-        even if it compiled.
-    
-    sysconf() works. An alternative would have been to use

-    xz: Don't fail if stdin doesn't support O_NONBLOCK.
-    
-    It's a problem at least on OpenBSD which doesn't support
-    O_NONBLOCK on e.g. /dev/null. I'm not surprised if it's
-    a problem on other OSes too since this behavior is allowed
-    in POSIX-1.2008.
-    
-    The code relying on this behavior was committed in June 2013
-    and included in 5.1.3alpha released on 2013-10-26. Clearly
-    the development releases only get limited testing.

-    Hiding them makes no sense since normally there's no error

+//    unlikely threading bugs) on the first call to lzma_crc32() to decide
+//    which implementation should be used.

-/// the slice-by-four algorithm. This is the same idea that is
-/// used in crc32_fast.c, but for CRC64 we use only four tables
-/// instead of eight to avoid increasing CPU cache usage.
-///
-/// crc64_clmul uses 32/64-bit x86 SSSE3, SSE4.1, and CLMUL instructions.
-/// It was derived from
-/// https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/fast-crc-computation-generic-polynomials-pclmulqdq-paper.pdf
-/// and the public domain code from https://github.com/rawrunprotected/crc
-/// (URLs were checked on 2022-11-07).
-///
-/// FIXME: Builds for 32-bit x86 use crc64_x86.S by default instead
-/// of this file and thus CLMUL version isn't available on 32-bit x86
-/// unless configured with --disable-assembler. Even then the lookup table
-/// isn't omitted in crc64_table.c since it doesn't know that assembly

+// (This prob update method is a tiny bit different from LZMA SDK 23.01.
+// In the LZMA SDK a single register is reserved solely for a constant to

+// In bittree decoding, each (unrolled) loop iteration decodes one bit
+// and needs one prob variable. To make it faster, the prob variable of
+// the iteration N+1 is loaded during iteration N. There are two possible
+// prob variables to choose from for N+1. Both are loaded from memory and
+// the correct one is chosen with CMOV using the same CF as is used for
+// other things described above.
+//
+// This preloading/prefetching requires an extra register. To avoid
+// useless moves from "preloaded prob register" to "current prob register",
+// the macros swap between the two registers for odd and even iterations.
+//
+// * * *
+//
+// Finally, the decoded bit has to be stored in "symbol". Since the negation
+// of the bit is in CF, this can be done with SBB: symbol -= CF - 1. That is,
+// if the decoded bit is 0 (CF==1) the operation is a no-op "symbol -= 0"
+// and when bit is 1 (CF==0) the operation is "symbol -= 0 - 1" which is
+// the same as "symbol += 1".
+//
+// The instructions for all things are intertwined for a few reasons:
+//   - freeing temporary registers for new use
+//   - not modifying CF too early
+//   - instruction scheduling
+//
+// The first and last iterations can cheat a little. For example,

+
+RISC-V filtering
+================
+
+    RV32I and RV64I, possibly combined with extensions C, Zfh, F, D,
+    and Q, are identical enough that the same filter works for both.
+
+    The instruction encoding is always little endian, even on systems
+    with big endian data access. Thus the same filter works for both
+    endiannesses.
+
+    The following instructions have program counter relative
+    (pc-relative) behavior:
+
+JAL
+---
+
+    JAL is used for function calls (including tail calls) and
+    unconditional jumps within functions. Jumps within functions
+    aren't useful to filter because the absolute addresses often
+    appear only once or at most a few times. Tail calls and jumps
+    within functions look the same to a simple filter so neither
+    are filtered, that is, JAL x0 is ignored (the ABI name of the
+    register x0 is "zero").
+
+    Almost all calls store the return address to register x1 (ra)
+    or x5 (t0). To reduce false matches when the filter is applied
+    to non-code data, only the JAL instructions that use x1 or x5
+    are converted. JAL has pc-relative range of +/-1 MiB so longer
+    calls and jumps need another method (AUIPC+JALR).
+
+C.J and C.JAL
+-------------
+
+    C.J and C.JAL have pc-relative range of +/-2 KiB.
+
+    C.J is for tail calls and jumps within functions and isn't
+    filtered for the reasons mentioned for JAL x0.
+
+    C.JAL is an RV32C-only instruction. Its encoding overlaps with
+    RV64C-only C.ADDIW which is a common instruction. So if filtering
+    C.JAL was useful (it wasn't tested) then a separate filter would
+    be needed for RV32 and RV64. Also, false positives would be a
+    significant problem when the filter is applied to non-code data
+    because C.JAL needs only five bits to match. Thus, this filter
+    doesn't modify C.JAL instructions.
+
+BEQ, BNE, BLT, BGE, BLTU, BGEU, C.BEQZ, and C.BNEZ
+--------------------------------------------------
+
+    These are conditional branches with pc-relative range
+    of +/-4 KiB (+/-256 B for C.*). The absolute addresses often
+    appear only once and very short distances are the most common,
+    so filtering these instructions would make compression worse.
+
+AUIPC with rd != x0
+-------------------
+
+    AUIPC is paired with a second instruction (inst2) to do
+    pc-relative jumps, calls, loads, stores, and for taking
+    an address of a symbol. AUIPC has a 20-bit immediate and
+    the possible inst2 choices have a 12-bit immediate.
+
+    AUIPC stores pc + 20-bit signed immediate to a register.
+    The immediate encodes a multiple of 4 KiB so AUIPC itself
+    has a pc-relative range of +/-2 GiB. AUIPC does *NOT* set
+    the lowest 12 bits of the result to zero! This means that
+    the 12-bit immediate in inst2 cannot just include the lowest
+    12 bits of the absolute address as is; the immediate has to
+    compensate for the lowest 12 bits that AUIPC copies from the
+    program counter. This means that a good filter has to convert
+    not only AUIPC but also the paired inst2.
+
+    A strict filter would focus on filtering the following
+    AUIPC+inst2 pairs:
+
+      - AUIPC+JALR: Function calls, including tail calls.
+
+      - AUIPC+ADDI: Calculating the address of a function
+        or a global variable.
+
+      - AUIPC+load/store from the base instruction sets
+        (RV32I, RV64I) or from the floating point extensions
+        Zfh, F, D, and Q:
+          * RV32I: LB, LH, LW, LBU, LHU, SB, SH, SW
+          * RV64I has also: LD, LWU, SD
+          * Zhf: FLH, FSH
+          * F: FLW, FSW
+          * D: FLD, FSD
+          * Q: FLQ, FSQ
+
+    NOTE: AUIPC+inst2 can only be a pair if AUIPC's rd specifies
+    the same register as inst2's rs1.
+
+    Instead of strictly accepting only the above instructions as inst2,
+    this filter uses a much simpler condition: the lowest two bits of
+    inst2 must be set, that is, inst2 must not be a 16-bit compressed
+    instruction. So this will accept all 32-bit and possible future
+    extended instructions as a pair to AUIPC if the bits in AUIPC's
+    rd [11:7] match the bits [19:15] in inst2 (the bits that I-type and
+    S-type instructions use for rs1). Testing showed that this relaxed
+    condition for inst2 did not consistently or significantly affect
+    compression ratio but it reduced code size and improved speed.
+
+    Additionally, the paired instruction is always treated as an I-type
+    instruction. The S-type instructions used by stores (SB, SH, SW,
+    etc.) place the lowest 5 bits of the immediate in a different
+    location than I-type instructions. AUIPC+store pairs are less
+    common than other pairs, and testing showed that the extra
+    code required to handle S-type instructions was not worth the
+    compression ratio gained.
+
+    AUIPC+inst2 don't necessarily appear sequentially next to each
+    other although very often they do. Especially AUIPC+JALR are
+    sequential as that may allow instruction fusion in processors
+    (and perhaps help branch prediction as a fused AUIPC+JALR is
+    a direct branch while JALR alone is an indirect branch).
+
+    Clang 16 can generate code where AUIPC+inst2 is split:
+
+      - AUIPC is outside a loop and inst2 (load/store) is inside
+        the loop. This way the AUIPC instruction needs to be
+        executed only once.
+
+      - Load-modify-store may have AUIPC for the load and the same
+        AUIPC-result is used for the store too. This may get combined
+        with AUIPC being outside the loop.
+
+      - AUIPC is before a conditional branch and inst2 is hundreds
+        of bytes away at the branch target.
+
+      - Inner and outer pair:
+
+            auipc   a1,0x2f
+            auipc   a2,0x3d
+            ld      a2,-500(a2)
+            addi    a1,a1,-233
+
+      - Many split pairs with an untaken conditional branch between:
+
+            auipc   s9,0x1613   # Pair 1
+            auipc   s4,0x1613   # Pair 2
+            auipc   s6,0x1613   # Pair 3
+            auipc   s10,0x1613  # Pair 4
+            beqz    a5,a3baae
+            ld      a0,0(a6)
+            ld      a6,246(s9)  # Pair 1
+            ld      a1,250(s4)  # Pair 2
+            ld      a3,254(s6)  # Pair 3
+            ld      a4,258(s10) # Pair 4
+
+    It's not possible to find all split pairs in a filter like this.
+    At least in 2024, simple sequential pairs are 99 % of AUIPC uses
+    so filtering only such pairs gives good results and makes the
+    filter simpler. However, it's possible that future compilers will
+    produce different code where sequential pairs aren't as common.
+
+    This filter doesn't convert AUIPC instructions alone because:
+
+    (1) The conversion would be off-by-one (or off-by-4096) half the
+        time because the lowest 12 bits from inst2 (inst2_imm12)
+        aren't known. We only know that the absolute address is
+        pc + AUIPC_imm20 + [-2048, +2047] but there is no way to
+        know the exact 4096-byte multiple (or 4096 * n + 2048):
+        there are always two possibilities because AUIPC copies
+        the 12 lowest bits from pc instead of zeroing them.
+
+        NOTE: The sign-extension of inst2_imm12 adds a tiny bit
+        of extra complexity to AUIPC math in general but it's not
+        the reason for this problem. The sign-extension only changes
+        the relative position of the pc-relative 4096-byte window.
+
+    (2) Matching AUIPC instruction alone requires only seven bits.
+        When the filter is applied to non-code data, that leads
+        to many false positives which make compression worse.
+        As long as most AUIPC+inst2 pairs appear as two consecutive
+        instructions, converting only such pairs gives better results.
+
+    In assembly, AUIPC+inst2 tend to look like this:
+
+        # Call:
+        auipc   ra, 0x12345
+        jalr    ra, -42(ra)
+
+        # Tail call:
+        auipc   t1, 0x12345
+        jalr    zero, -42(t1)
+
+        # Getting the absolute address:
+        auipc   a0, 0x12345
+        addi    a0, a0, -42
+
+        # rd of inst2 isn't necessarily the same as rs1 even
+        # in cases where there is no reason to preserve rs1.
+        auipc   a0, 0x12345
+        addi    a1, a0, -42
+
+    As of 2024, 16-bit instructions from the C extension don't
+    appear as inst2. The RISC-V psABI doesn't list AUIPC+C.* as
+    a linker relaxation type explicitly but it's not disallowed
+    either. Usefulness is limited as most of the time the lowest
+    12 bits won't fit in a C instruction. This filter doesn't
+    support AUIPC+C.* combinations because this makes the filter
+    simpler, there are no test files, and it hopefully will never
+    be needed anyway.
+
+    (Compare AUIPC to ARM64 where ADRP does set the lowest 12 bits
+    to zero. The paired instruction has the lowest 12 bits of the
+    absolute address as is in a zero-extended immediate. Thus the
+    ARM64 filter doesn't need to care about the instructions that
+    are paired with ADRP. An off-by-4096 issue can still occur if
+    the code section isn't aligned with the filter's start offset.
+    It's not a problem with standalone ELF files but Windows PE
+    files need start_offset=3072 for best results. Also, a .tar
+    stores files with 512-byte alignment so most of the time it
+    won't be the best for ARM64.)
+
+AUIPC with rd == x0
+-------------------
+
+    AUIPC instructions with rd=x0 are reserved for HINTs in the base
+    instruction set. Such AUIPC instructions are never filtered.
+
+    As of January 2024, it seems likely that AUIPC with rd=x0 will
+    be used for landing pads (pseudoinstruction LPAD). LPAD is used
+    to mark valid targets for indirect jumps (for JALR), for example,
+    beginnings of functions. The 20-bit immediate in LPAD instruction
+    is a label, not a pc-relative address. Thus it would be
+    counterproductive to convert AUIPC instructions with rd=x0.
+
+    Often the next instruction after LPAD won't have rs1=x0 and thus
+    the filtering would be skipped for that reason alone. However,
+    it's not good to rely on this. For example, consider a function
+    that begins like this:
+
+        int foo(int i)
+        {
+            if (i <= 234) {
+                ...
+            }
+
+    A compiler may generate something like this:
+
+        lpad    0x54321
+        li      a5, 234
+        bgt     a0, a5, .L2
+
+    Converting the pseudoinstructions to raw instructions:
+
+        auipc   x0, 0x54321
+        addi    x15, x0, 234
+        blt     x15, x10, .L2
+
+    In this case the filter would undesirably convert the AUIPC+ADDI
+    pair if the filter didn't explicitly skip AUIPC instructions
+    that have rd=x0.
