+1.2.4. OpenVMS
+

+    Building XZ Utils on Windows is supported under MinGW + MSYS,

+    redistributable .zip or .7z file. See windows/INSTALL-Windows.txt
+    for more information.
 
-    MSVC doesn't support C99, thus it is not possible to use MSVC to
-    compile XZ Utils. However, it is possible to use liblzma.dll from
-    MSVC once liblzma.dll has been built with MinGW. The required

-    "lib" command shipped in MSVC:
+    It might be possible to build liblzma with a non-GNU toolchain too,

+    the command line tools with non-GNU toolchains will be harder than

+2.1. Static vs. dynamic linking of liblzma
+
+    On 32-bit x86, linking against static liblzma can give a minor
+    speed improvement. Static libraries on x86 are usually compiled as
+    position-dependent code (non-PIC) and shared libraries are built as
+    position-independent code (PIC). PIC wastes one register, which can
+    make the code slightly slower compared to a non-PIC version. (Note
+    that this doesn't apply to x86-64.)
+
+    If you want to link xz against static liblzma, the simplest way
+    is to pass --disable-shared to configure. If you want also shared
+    liblzma, run configure again and run "make install" only for
+    src/liblzma.
+
+
+2.2. Optimizing xzdec and lzmadec
+
+    xzdec and lzmadec are intended to be relatively small instead of
+    optimizing for the best speed. Thus, it is a good idea to build
+    xzdec and lzmadec separately:
+
+      - To link the tools against static liblzma, pass --disable-shared
+        to configure.
+
+      - To select somewhat size-optimized variant of some things in
+        liblzma, pass --enable-small to configure.
+
+      - Tell the compiler to optimize for size instead of speed.
+        E.g. with GCC, put -Os into CFLAGS.
+
+      - xzdec and lzmadec will never use multithreading capabilities of
+        liblzma. You can avoid dependency on libpthread by passing
+        --disable-threads to configure.
+
+      - There are and will be no translated messages for xzdec and
+        lzmadec, so it is fine to pass also --disable-nls to configure.
+
+      - Only decoder code is needed, so you can speed up the build
+        slightly by passing --disable-encoders to configure. This
+        shouldn't affect the final size of the executables though,
+        because the linker is able to omit the encoder code anyway.
+
+    If you have no use for xzdec or lzmadec, you can disable them with
+    --disable-xzdec and --disable-lzmadec.

+
+    On some systems where symbol visibility isn't supported, GCC may

+    many compiler warnings. You can avoid the warnings by forcing the

+
+
+4.5. "make check" fails
+
+    If the other tests pass but test_scripts.sh fails, then the problem
+    is in the scripts in src/scripts. Comparing the contents of
+    tests/xzgrep_test_output to tests/xzgrep_expected_output might
+    give a good idea about problems in xzgrep. One possibility is that
+    some tools are missing from the current PATH or the tools lack
+    support for some POSIX features. This can happen at least on
+    Solaris where the tools in /bin may be ancient but good enough
+    tools are available in /usr/xpg4/bin or /usr/xpg6/bin. One fix
+    for this problem is described in section 3.2 of this file.
+
+    If tests other than test_scripts.sh fail, a likely reason is that
+    libtool links the test programs against an installed version of
+    liblzma instead of the version that was just built. This is
+    obviously a bug which seems to happen on some platforms.
+    A workaround is to uninstall the old liblzma versions first.
+
+    If the problem isn't any of those described above, then it's likely
+    a bug in XZ Utils or in the compiler. See the platform-specific

+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'.  Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated.  The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the `DESTDIR' variable.  For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names.  The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,

+XZ Utils Release Notes
+======================
+
+5.0.8 (2014-12-21)
+
+    * Fixed an old bug in xzgrep that affected OpenBSD and probably
+      a few other operating systems too.
+
+    * Updated French and German translations.
+
+    * Added support for detecting the amount of RAM on AmigaOS/AROS.
+
+    * Minor build system updates.
+
+
+5.0.7 (2014-09-20)
+
+    * Fix regressions introduced in 5.0.6:
+
+        - Fix building with non-GNU make.
+
+        - Fix invalid Libs.private value in liblzma.pc which broke
+          static linking against liblzma if the linker flags were
+          taken from pkg-config.
+
+
+5.0.6 (2014-09-14)
+
+    * xzgrep now exits with status 0 if at least one file matched.
+
+    * A few minor portability and build system fixes
+
+
+5.0.5 (2013-06-30)
+
+    * lzmadec and liblzma's lzma_alone_decoder(): Support decompressing
+      .lzma files that have less common settings in the headers
+      (dictionary size other than 2^n or 2^n + 2^(n-1), or uncompressed
+      size greater than 256 GiB). The limitations existed to avoid false
+      positives when detecting .lzma files. The lc + lp <= 4 limitation
+      still remains since liblzma's LZMA decoder has that limitation.
+
+      NOTE: xz's .lzma support or liblzma's lzma_auto_decoder() are NOT
+      affected by this change. They still consider uncommon .lzma headers
+      as not being in the .lzma format. Changing this would give way too
+      many false positives.
+
+    * xz:
+
+        - Interaction of preset and custom filter chain options was
+          made less illogical. This affects only certain less typical
+          uses cases so few people are expected to notice this change.
+
+          Now when a custom filter chain option (e.g. --lzma2) is
+          specified, all preset options (-0 ... -9, -e) earlier are on
+          the command line are completely forgotten. Similarly, when
+          a preset option is specified, all custom filter chain options
+          earlier on the command line are completely forgotten.
+
+          Example 1: "xz -9 --lzma2=preset=5 -e" is equivalent to "xz -e"
+          which is equivalent to "xz -6e". Earlier -e didn't put xz back
+          into preset mode and thus the example command was equivalent
+          to "xz --lzma2=preset=5".
+
+          Example 2: "xz -9e --lzma2=preset=5 -7" is equivalent to
+          "xz -7". Earlier a custom filter chain option didn't make
+          xz forget the -e option so the example was equivalent to
+          "xz -7e".
+
+        - Fixes and improvements to error handling.
+
+        - Various fixes to the man page.
+
+    * xzless: Fixed to work with "less" versions 448 and later.
+
+    * xzgrep: Made -h an alias for --no-filename.
+
+    * Include the previously missing debug/translation.bash which can
+      be useful for translators.
+
+    * Include a build script for Mac OS X. This has been in the Git
+      repository since 2010 but due to a mistake in Makefile.am the
+      script hasn't been included in a release tarball before.
+
+
+5.0.4 (2012-06-22)
+
+    * liblzma:
+
+        - Fix lzma_index_init(). It could crash if memory allocation
+          failed.
+
+        - Fix the possibility of an incorrect LZMA_BUF_ERROR when a BCJ
+          filter is used and the application only provides exactly as
+          much output space as is the uncompressed size of the file.
+
+        - Fix a bug in doc/examples_old/xz_pipe_decompress.c. It didn't
+          check if the last call to lzma_code() really returned
+          LZMA_STREAM_END, which made the program think that truncated
+          files are valid.
+
+        - New example programs in doc/examples (old programs are now in
+          doc/examples_old). These have more comments and more detailed
+          error handling.
+
+    * Fix "xz -lvv foo.xz". It could crash on some corrupted files.
+
+    * Fix output of "xz --robot -lv" and "xz --robot -lvv" which
+      incorrectly printed the filename also in the "foo (x/x)" format.
+
+    * Fix exit status of "xzdiff foo.xz bar.xz".
+
+    * Fix exit status of "xzgrep foo binary_file".
+
+    * Fix portability to EBCDIC systems.
+
+    * Fix a configure issue on AIX with the XL C compiler. See INSTALL
+      for details.
+
+    * Update French, German, Italian, and Polish translations.
+
+
+5.0.3 (2011-05-21)
+
+    * liblzma fixes:
+
+        - A memory leak was fixed.
+
+        - lzma_stream_buffer_encode() no longer creates an empty .xz
+          Block if encoding an empty buffer. Such an empty Block with
+          LZMA2 data would trigger a bug in 5.0.1 and older (see the
+          first bullet point in 5.0.2 notes). When releasing 5.0.2,
+          I thought that no encoder creates this kind of files but
+          I was wrong.
+
+        - Validate function arguments better in a few functions. Most
+          importantly, specifying an unsupported integrity check to
+          lzma_stream_buffer_encode() no longer creates a corrupt .xz
+          file. Probably no application tries to do that, so this
+          shouldn't be a big problem in practice.
+
+        - Document that lzma_block_buffer_encode(),
+          lzma_easy_buffer_encode(), lzma_stream_encoder(), and
+          lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK.
+
+        - The return values of the _memusage() functions are now
+          documented better.
+
+    * Fix command name detection in xzgrep. xzegrep and xzfgrep now
+      correctly use egrep and fgrep instead of grep.
+
+    * French translation was added.
+
+
+5.0.2 (2011-04-01)
+
+    * LZMA2 decompressor now correctly accepts LZMA2 streams with no
+      uncompressed data. Previously it considered them corrupt. The
+      bug can affect applications that use raw LZMA2 streams. It is
+      very unlikely to affect .xz files because no compressor creates
+      .xz files with empty LZMA2 streams. (Empty .xz files are a
+      different thing than empty LZMA2 streams.)
+
+    * "xz --suffix=.foo filename.foo" now refuses to compress the
+      file due to it already having the suffix .foo. It was already
+      documented on the man page, but the code lacked the test.
+
+    * "xzgrep -l foo bar.xz" works now.
+
+    * Polish translation was added.
+
+
+5.0.1 (2011-01-29)
+
+    * xz --force now (de)compresses files that have setuid, setgid,
+      or sticky bit set and files that have multiple hard links.
+      The man page had it documented this way already, but the code
+      had a bug.
+
+    * gzip and bzip2 support in xzdiff was fixed.
+
+    * Portability fixes
+
+    * Minor fix to Czech translation
+
+
+5.0.0 (2010-10-23)
+
+    Only the most important changes compared to 4.999.9beta are listed
+    here. One change is especially important:
+
+      * The memory usage limit is now disabled by default. Some scripts
+        written before this change may have used --memory=max on xz command
+        line or in XZ_OPT. THESE USES OF --memory=max SHOULD BE REMOVED
+        NOW, because they interfere with user's ability to set the memory
+        usage limit himself. If user-specified limit causes problems to
+        your script, blame the user.
+
+    Other significant changes:
+
+      * Added support for XZ_DEFAULTS environment variable. This variable
+        allows users to set default options for xz, e.g. default memory
+        usage limit or default compression level. Scripts that use xz
+        must never set or unset XZ_DEFAULTS. Scripts should use XZ_OPT
+        instead if they need a way to pass options to xz via an
+        environment variable.
+
+      * The compression settings associated with the preset levels
+        -0 ... -9 have been changed. --extreme was changed a little too.
+        It is now less likely to make compression worse, but with some
+        files the new --extreme may compress slightly worse than the old
+        --extreme.
+
+      * If a preset level (-0 ... -9) is specified after a custom filter
+        chain options have been used (e.g. --lzma2), the custom filter
+        chain will be forgotten. Earlier the preset options were
+        completely ignored after custom filter chain options had been
+        seen.
+
+      * xz will create sparse files when decompressing if the uncompressed
+        data contains long sequences of binary zeros. This is done even
+        when writing to standard output that is connected to a regular
+        file and certain additional conditions are met to make it safe.
+
+      * Support for "xz --list" was added. Combine with --verbose or
+        --verbose --verbose (-vv) for detailed output.
+
+      * I had hoped that liblzma API would have been stable after
+        4.999.9beta, but there have been a couple of changes in the
+        advanced features, which don't affect most applications:
+
+          - Index handling code was revised. If you were using the old
+            API, you will get a compiler error (so it's easy to notice).
+
+          - A subtle but important change was made to the Block handling
+            API. lzma_block.version has to be initialized even for
+            lzma_block_header_decode(). Code that doesn't do it will work
+            for now, but might break in the future, which makes this API
+            change easy to miss.
+
+      * The major soname has been bumped to 5.0.0. liblzma API and ABI
+        are now stable, so the need to recompile programs linking against
+        liblzma shouldn't arise soon.

-
-
-4.1. Static vs. dynamic linking of liblzma
-
-    The default is to link the most important command line tools against
-    static liblzma, and the less important tools against shared liblzma.
-    This can be changed by passing --enable-dynamic to configure, or by
-    not building static libraries at all by passing --disable-static
-    to configure. It is mildly recommended that you use the default, but
-    the configure options make it easy to do otherwise if the distro policy
-    so requires.
-
-    On 32-bit x86, linking against static liblzma can give a minor
-    speed improvement. Static libraries on x86 are usually compiled as
-    position-dependent code (non-PIC) and shared libraries are built as
-    position-independent code (PIC). PIC wastes one register, which can
-    make the code slightly slower compared to a non-PIC version. (Note
-    that this doesn't apply to x86-64.)
-
-    Linking against static liblzma avoids a dependency on liblzma shared
-    library, and makes it slightly easier to copy the command line tools
-    between systems (e.g. quick 'n' dirty emergency recovery of some
-    files). It also allows putting the command line tools to /bin while
-    leaving liblzma to /usr/lib (assuming that your distribution uses
-    such a file system hierarchy), if no other file in /bin would require
-    liblzma.
-
-    If you don't want to distribute static libraries but you still
-    want to link the command line tools against static liblzma, it is
-    probably easiest to build both static and shared liblzma, but after
-    "make DESTDIR=$PKG install" remove liblzma.a and modify liblzma.la
-    to not contain a reference to liblzma.a.
-
-
-4.2. Optimizing xzdec and lzmadec
-
-    xzdec and lzmadec are intended to be relatively small instead of
-    optimizing for the best speed. Thus, it is a good idea to build
-    xzdec and lzmadec separately:
-
-      - Only decoder code is needed, so you can speed up the build
-        slightly by passing --disable-encoders to configure. This
-        shouldn't affect the final size of the executables though,
-        because the linker is able to omit the encoder code anyway.
-
-      - xzdec and lzmadec will never use multithreading capabilities of
-        liblzma. You can avoid dependency on libpthread by passing
-        --disable-threads to configure.
-
-      - There are and will be no translated messages for xzdec and
-        lzmadec, so it is fine to pass also --disable-nls to configure.
-
-      - To select somewhat size-optimized variant of some things in
-        liblzma, pass --enable-small to configure.
-
-      - Tell the compiler to optimize for size instead of speed.
-        E.g. with GCC, put -Os into CFLAGS.
+    xzdec and lzmadec don't provide any functionality that isn't already
+    available in the xz tool. Shipping xzdec and lzmadec without size
+    optimization and statically-linked liblzma isn't very useful. Doing
+    that would give users the xzdec man page, which may make it easier
+    for people to find out that such tools exists, but the executables
+    wouldn't have any advantage over the full-featured xz.

-4. Other implementations of the .xz format
+4. Translating the xz tool
+--------------------------
+
+    The messages from the xz tool have been translated into a few
+    languages. Before starting to translate into a new language, ask
+    the author whether someone else hasn't already started working on it.
+
+    Test your translation. Testing includes comparing the translated
+    output to the original English version by running the same commands
+    in both your target locale and with LC_ALL=C. Ask someone to
+    proof-read and test the translation.
+
+    Testing can be done e.g. by installing xz into a temporary directory:
+
+        ./configure --disable-shared --prefix=/tmp/xz-test
+        # <Edit the .po file in the po directory.>
+        make -C po update-po
+        make install
+        bash debug/translation.bash | less
+        bash debug/translation.bash | less -S  # For --list outputs
+
+    Repeat the above as needed (no need to re-run configure though).
+
+    Note especially the following:
+
+      - The output of --help and --long-help must look nice on
+        an 80-column terminal. It's OK to add extra lines if needed.
+
+      - In contrast, don't add extra lines to error messages and such.
+        They are often preceded with e.g. a filename on the same line,
+        so you have no way to predict where to put a \n. Let the terminal
+        do the wrapping even if it looks ugly. Adding new lines will be
+        even uglier in the generic case even if it looks nice in a few
+        limited examples.
+
+      - Be careful with column alignment in tables and table-like output
+        (--list, --list --verbose --verbose, --info-memory, --help, and
+        --long-help):
+
+          * All descriptions of options in --help should start in the
+            same column (but it doesn't need to be the same column as
+            in the English messages; just be consistent if you change it).
+            Check that both --help and --long-help look OK, since they
+            share several strings.
+
+          * --list --verbose and --info-memory print lines that have
+            the format "Description:   %s". If you need a longer
+            description, you can put extra space between the colon
+            and %s. Then you may need to add extra space to other
+            strings too so that the result as a whole looks good (all
+            values start at the same column).
+
+          * The columns of the actual tables in --list --verbose --verbose
+            should be aligned properly. Abbreviate if necessary. It might
+            be good to keep at least 2 or 3 spaces between column headings
+            and avoid spaces in the headings so that the columns stand out
+            better, but this is a matter of opinion. Do what you think
+            looks best.
+
+      - Be careful to put a period at the end of a sentence when the
+        original version has it, and don't put it when the original
+        doesn't have it. Similarly, be careful with \n characters
+        at the beginning and end of the strings.
+
+      - Read the TRANSLATORS comments that have been extracted from the
+        source code and included in xz.pot. If they suggest testing the
+        translation with some type of command, do it. If testing needs
+        input files, use e.g. tests/files/good-*.xz.
+
+      - When updating the translation, read the fuzzy (modified) strings
+        carefully, and don't mark them as updated before you actually
+        have updated them. Reading through the unchanged messages can be
+        good too; sometimes you may find a better wording for them.
+
+      - If you find language problems in the original English strings,
+        feel free to suggest improvements. Ask if something is unclear.
+
+      - The translated messages should be understandable (sometimes this
+        may be a problem with the original English messages too). Don't
+        make a direct word-by-word translation from English especially if
+        the result doesn't sound good in your language.
+
+    In short, take your time and pay attention to the details. Making
+    a good translation is not a quick and trivial thing to do. The
+    translated xz should look as polished as the English version.

+========================
+
+Introduction
+
+    The examples are written so that the same comments aren't
+    repeated (much) in later files.
+
+    On POSIX systems, the examples should build by just typing "make".
+
+    The examples that use stdin or stdout don't set stdin and stdout
+    to binary mode. On systems where it matters (e.g. Windows) it is
+    possible that the examples won't work without modification.
+
+
+List of examples
+
+    01_compress_easy.c                  Multi-call compression using
+                                        a compression preset
+
+    02_decompress.c                     Multi-call decompression
+
+    03_compress_custom.c                Like 01_compress_easy.c but using
+                                        a custom filter chain
+                                        (x86 BCJ + LZMA2)

+        XZ_DEFAULTS=--memlimit-compress=150MiB
+        export XZ_DEFAULTS

+Q:  How do I create files that can be decompressed with XZ Embedded?

+
+    Or if a BCJ filter is needed too, e.g. if compressing
+    a kernel image for PowerPC:
+
+        xz --check=crc32 --powerpc --lzma2=preset=6e,dict=64KiB
+
+    Adjust the dictionary size to get a good compromise between
+    compression ratio and decompressor memory usage. Note that
+    in single-call decompression mode of XZ Embedded, a big
+    dictionary doesn't increase memory usage.
+
+
+Q:  Will xz support threaded compression?
+
+A:  It is planned and has been taken into account when designing
+    the .xz file format. Eventually there will probably be three types
+    of threading, each method having its own advantages and disadvantages.
+
+    The simplest method is splitting the uncompressed data into blocks
+    and compressing them in parallel independent from each other.
+    Since the blocks are compressed independently, they can also be
+    decompressed independently. Together with the index feature in .xz,
+    this allows using threads to create .xz files for random-access
+    reading. This also makes threaded decompression possible, although
+    it is not clear if threaded decompression will ever be implemented.
+
+    The independent blocks method has a couple of disadvantages too. It
+    will compress worse than a single-block method. Often the difference
+    is not too big (maybe 1-2 %) but sometimes it can be too big. Also,
+    the memory usage of the compressor increases linearly when adding
+    threads.
+
+    Match finder parallelization is another threading method. It has
+    been in 7-Zip for ages. It doesn't affect compression ratio or
+    memory usage significantly. Among the three threading methods, only
+    this is useful when compressing small files (files that are not
+    significantly bigger than the dictionary). Unfortunately this method
+    scales only to about two CPU cores.
+
+    The third method is pigz-style threading (I use that name, because
+    pigz <http://www.zlib.net/pigz/> uses that method). It doesn't
+    affect compression ratio significantly and scales to many cores.
+    The memory usage scales linearly when threads are added. This isn't
+    significant with pigz, because Deflate uses only a 32 KiB dictionary,
+    but with LZMA2 the memory usage will increase dramatically just like
+    with the independent-blocks method. There is also a constant
+    computational overhead, which may make pigz-method a bit dull on
+    dual-core compared to the parallel match finder method, but with more
+    cores the overhead is not a big deal anymore.
+
+    Combining the threading methods will be possible and also useful.
+    E.g. combining match finder parallelization with pigz-style threading
+    can cut the memory usage by 50 %.
+
+    It is possible that the single-threaded method will be modified to
+    create files identical to the pigz-style method. We'll see once
+    pigz-style threading has been implemented in liblzma.

 Building
 
-    Just run "make" in this directory (the directory containing this
-    README). You should get liblzma.a, xz.exe, xzdec.exe, and
-    lzmadec.exe. Of these, probably xz.exe is the only interesting one.
-
-    Note: You need to have an environment that supports long filenames.
+    You need to have an environment that supports long filenames (LFN).
     Once you have built XZ Utils, the resulting binaries can be run

-
-Additional Make Flags and Targets
-
-    You may want to try some additional optimizations, which may or
-    may not make the code faster (and may or may not hit possible
-    compiler bugs more easily):
-
-        make CFLAGS="-O3 -fomit-frame-pointer -funroll-loops"
-
-    If you want to enable assertions (the assert() macro), use DEBUG=1.
-    You may want to disable optimizations too if you plan to actually
-    debug the code. Never use DEBUG=1 for production builds!
-
-        make DEBUG=1 CFLAGS="-g -O0"
+    Run "make" in this directory (the directory containing this README).
+    You should get xz.exe (and a bunch of temporary files). Other tools
+    are not built. Having e.g. xzdec.exe doesn't save much space compared
+    to xz.exe, because the DJGPP runtime makes the .exe quite big anyway.
 
 
 Bugs
 
-    "make clean" may remove src/xz/hardware.c when it tries to remove
-    src/xz/hardware-fixed.c. This is probably a bug somewhere in the
-    DOS environment I use. Maybe it tries truncated 8.3 name first and
-    since that gives a name of an existing file, it doesn't look for
-    long filename.
+    xz doesn't necessarily work in Dosbox. It should work in DOSEMU.
 
-    "xz -fc /dev/tty" hangs at least in DOSEMU and cannot be interrupted
-    by pressing C-c. Maybe xz should never accept non-regular files on
-    DOS even when --force is used.
-
-    Using different memory usage limit for encoding and decoding doesn't
-    make sense under pure DOS. Maybe it is still OK when running under
-    Windows.
-
-    The progress indicator of "xz -v" doesn't get updated when running
-    under Dosbox, but it works in DOSEMU. I currently (2009-02-13) don't
-    know if it works in other environments.
-
-    Report bugs to <lasse.collin@tukaani.org> (in English or Finnish).
+    Pressing Ctrl-c or Ctrl-Break won't remove the incomplete target file
+    when running under Windows XP Command Prompt (something goes wrong
+    with SIGINT handling). It works correctly under Windows 95/98/98SE/ME.

-# SYNOPSIS
-#
-#   ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
-#
-# DESCRIPTION
-#
-#   This macro figures out how to build C programs using POSIX threads.
-#   It sets the PTHREAD_LIBS output variable to the threads library and
-#   linker flags, and the PTHREAD_CFLAGS output variable to any special
-#   C compiler flags that are needed. (The user can also force certain
-#   compiler flags/libs to be tested by setting these environment
-#   variables.)
-#
-#   Also sets PTHREAD_CC to any special C compiler that is needed for
-#   multi-threaded programs (defaults to the value of CC otherwise).
-#   (This is necessary on AIX to use the special cc_r compiler alias.)
-#
-#   NOTE: You are assumed to not only compile your program with these
-#   flags, but also link it with them as well. e.g. you should link
-#   with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
-#   $LIBS
-#
-#   If you are only building threads programs, you may wish to use
-#   these variables in your default LIBS, CFLAGS, and CC:
-#
-#          LIBS="$PTHREAD_LIBS $LIBS"
-#          CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
-#          CC="$PTHREAD_CC"
-#
-#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
-#   constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
-#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
-#
-#   ACTION-IF-FOUND is a list of shell commands to run if a threads
-#   library is found, and ACTION-IF-NOT-FOUND is a list of commands to
-#   run it if it is not found. If ACTION-IF-FOUND is not specified, the
-#   default action will define HAVE_PTHREAD.
-#
-#   Please let the authors know if this macro fails on any platform, or
-#   if you have any other suggestions or comments. This macro was based
-#   on work by SGJ on autoconf scripts for FFTW (http://www.fftw.org/)
-#   (with help from M. Frigo), as well as ac_pthread and hb_pthread
-#   macros posted by Alejandro Forero Cuervo to the autoconf macro
-#   repository. We are also grateful for the helpful feedback of
-#   numerous users.

+#
+#     - BSDs use sysctl().
+#
+#     - Tru64 uses getsysinfo().
+#
+#     - HP-UX uses pstat_getstatic().

+/// Endianness related integer operations (XX = 16, 32, or 64; Y = b or l):
+///   - Byte swapping: bswapXX(num)
+///   - Byte order conversions to/from native: convXXYe(num)
+///   - Aligned reads: readXXYe(ptr)
+///   - Aligned writes: writeXXYe(ptr, num)
+///   - Unaligned reads (16/32-bit only): unaligned_readXXYe(ptr)
+///   - Unaligned writes (16/32-bit only): unaligned_writeXXYe(ptr, num)
+///
+/// Since they can macros, the arguments should have no side effects since
+/// they may be evaluated more than once.
+///
+/// \todo       PowerPC and possibly some other architectures support
+///             byte swapping load and store instructions. This file
+///             doesn't take advantage of those instructions.
+///
+/// Bit scan operations for non-zero 32-bit integers:
+///   - Bit scan reverse (find highest non-zero bit): bsr32(num)
+///   - Count leading zeros: clz32(num)
+///   - Count trailing zeros: ctz32(num)
+///   - Bit scan forward (simply an alias for ctz32()): bsf32(num)
+///
+/// The above bit scan operations return 0-31. If num is zero,
+/// the result is undefined.
