It can't be 128 (probably - should change that). - - src and dest must then be aligned on ceil(w/8)-byte boundaries. - Moreover, bytes must be a multiple of ceil(w/8). If the variable - align is equal to ceil(w/8), then we will set s_start = src, - d_start = dest, s_top to (src+bytes) and d_top to (dest+bytes). - And we return -- the implementation will go ahead and do the - multiplication on individual words (e.g. using discrete logs). - - If align is greater than ceil(w/8), then the implementation needs - to work on groups of "align" bytes. For example, suppose you are - implementing BYTWO, without SSE. Then you will be doing the region - multiplication in units of 8 bytes, so align = 8. Or, suppose you - are doing a Quad table in GF(2^4). You will be doing the region - multiplication in units of 2 bytes, so align = 2. Or, suppose you - are doing split multiplication with SSE operations in GF(2^8). - Then align = 16. Worse yet, suppose you are doing split - multiplication with SSE operations in GF(2^16), with or without - ALTMAP. Then, you will be doing the multiplication on 256 bits at - a time. So align = 32. - - When align does not equal ceil(w/8), we split the region - multiplication into three parts. We are going to make s_start be - the first address greater than or equal to src that is a multiple - of align. s_top is going to be the largest address >= src+bytes - such that (s_top - s_start) is a multiple of align. We do the - same with d_start and d_top. When we say that "src and dest must - be aligned with respect to each other, we mean that s_start-src - must equal d_start-dest. - - Now, the region multiplication is done in three parts -- the part - between src and s_start must be done using single words. - Similarly, the part between s_top and src+bytes must also be done - using single words. The part between s_start and s_top will be - done in chunks of "align" bytes. - - One final thing -- if align > 16, then s_start and d_start will be - aligned on a 16 byte boundary. Perhaps we should have two - variables: align and chunksize. Then we'd have s_start & d_start - aligned to "align", and have s_top-s_start be a multiple of - chunksize. That may be less confusing, but it would be a big - change. - - Finally, if align = -1, then we are doing Cauchy multiplication, - using only XOR's. In this case, we're not going to care about - alignment because we are just doing XOR's. Instead, the only - thing we care about is that bytes must be a multiple of w. - - This is not to say that alignment doesn't matter in performance - with XOR's. See that discussion in gf_multby_one(). - - After you call gf_set_region_data(), the procedure - gf_do_initial_region_alignment() calls gf->multiply.w32() on - everything between src and s_start.

-Installation Instructions
-*************************

-without warranty of any kind.
-
-Basic Installation
-==================
-
-   Briefly, the shell command `./configure && make && make install'
-should configure, build, and install this package.  The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package.  Some packages provide this
-`INSTALL' file but do not implement all of the features documented
-below.  The lack of an optional feature in a given package is not
-necessarily a bug.  More recommendations for GNU packages can be found
-in *note Makefile Conventions: (standards)Makefile Conventions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-   The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.
-
-     Running `configure' might take a while.  While running, it prints
-     some messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package, generally using the just-built uninstalled binaries.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.  When installing into a prefix owned by root, it is
-     recommended that the package be configured and built as a regular
-     user, and only the `make install' phase executed with root
-     privileges.
-
-  5. Optionally, type `make installcheck' to repeat any self-tests, but
-     this time using the binaries in their final installed location.
-     This target does not install anything.  Running this target as a
-     regular user, particularly if the prior `make install' required
-     root privileges, verifies that the installation completed
-     correctly.
-
-  6. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-  7. Often, you can also type `make uninstall' to remove the installed
-     files again.  In practice, not all packages have tested that
-     uninstallation works correctly, even though it is required by the
-     GNU Coding Standards.
-
-  8. Some packages, particularly those that use Automake, provide `make
-     distcheck', which can by used by developers to test that all other
-     targets like `make install' and `make uninstall' work correctly.
-     This target is generally not run by end users.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  Run `./configure --help'
-for details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.  This
-is known as a "VPATH" build.
-
-   With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
-   On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple `-arch' options to the
-compiler but only a single `-arch' option to the preprocessor.  Like
-this:
-
-     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CPP="gcc -E" CXXCPP="g++ -E"
-
-   This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the `lipo' tool if you have problems.
-
-Installation Names
-==================
-
-   By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc.  You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX', where PREFIX must be an
-absolute file name.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.  In general, the
-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 `${prefix}', must each be overridden at install
-time for the entire installation to be relocated.  The approach of
-makefile variable overrides for each directory variable is required by
-the GNU Coding Standards, and ideally causes no recompilation.
-However, some platforms have known limitations with the semantics of
-shared libraries that end up requiring recompilation when using this
-method, particularly noticeable in packages that use GNU Libtool.
-
-   The second method involves providing the `DESTDIR' variable.  For
-example, `make install DESTDIR=/alternate/directory' will prepend
-`/alternate/directory' before all installation names.  The approach of
-`DESTDIR' overrides is not required by the GNU Coding Standards, and
-does not work on platforms that have drive letters.  On the other hand,
-it does better at avoiding recompilation issues, and works well even
-when some directory options were not specified in terms of `${prefix}'
-at `configure' time.
-
-Optional Features
-=================
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-   Some packages offer the ability to configure how verbose the
-execution of `make' will be.  For these packages, running `./configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with `make V=1'; while running `./configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with `make V=0'.
-
-Particular systems
-==================
-
-   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
-CC is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
-     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
-   HP-UX `make' updates targets which have the same time stamps as
-their prerequisites, which makes it generally unusable when shipped
-generated files such as `configure' are involved.  Use GNU `make'
-instead.
-
-   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its `' header file.  The option `-nodtk' can be used as
-a workaround.  If GNU CC is not installed, it is therefore recommended
-to try
-
-     ./configure CC="cc"
-
-and if that doesn't work, try
-
-     ./configure CC="cc -nodtk"
-
-   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
-directory contains several dysfunctional programs; working variants of
-these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
-in your `PATH', put it _after_ `/usr/bin'.
-
-   On Haiku, software installed for all users goes in `/boot/common',
-not `/usr/local'.  It is recommended to use the following options:
-
-     ./configure --prefix=/boot/common
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS
-     KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-   Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf limitation.  Until the limitation is lifted, you can use
-this workaround:
-
-     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
-     Print a summary of all of the options to `configure', and exit.
-
-`--help=short'
-`--help=recursive'
-     Print a summary of the options unique to this package's
-     `configure', and exit.  The `short' variant lists options used
-     only in the top level, while the `recursive' variant lists options
-     also present in any nested packages.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--prefix=DIR'
-     Use DIR as the installation prefix.  *note Installation Names::
-     for more details, including other options available for fine-tuning
-     the installation locations.
-
-`--no-create'
-`-n'
-     Run the configure checks, but stop before creating any output
-     files.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

-This is revision 2.0 of Jerasure.  This is pretty much Jerasure 1.2 without the
-original Galois Field backend.  Version 2.0 links directly to GF-Complete, which
-is more flexible than the original, and *much* faster, because it leverages SIMD
-instructions.
-Authors: James S. Plank (University of Tennessee)
-         Kevin M. Greenan (Box)
-
-------------------------------------------------------------
-
-The online home for jerasure is:
-
-  - http://jerasure.org/jerasure/jerasure
-
-------------------------------------------------------------
-
-External Documentation:
-
-See the file Manual.pdf for the programmer's manual and tutorial.
-
-See http://jerasure.org/jerasure/gf-complete for GF-Complete.
-
-NOTE: You must have GF-Complete installed (or compiled) in order to use Jerasure 2.0.
-
-There are two directories of source code:
-
-The src directory contains the jerasure code.
-The Examples directory contains the example programs.
-
-------------------------------------------------------------
-
-If you do not have Autoconf 2.65 or later installed, you can simply build
-from the tarball distribution:
-
-http://www.kaymgee.com/Kevin_Greenan/Software_files/jerasure.tar.gz
-
-Installing if you are allowed to install GF-Complete on your machine:
-(You can skip the autoreconf step if you're using a tarball distribution.)
-
-1.) Install GF-Complete
-2.) autoreconf --force --install (*skip* if you are building from tarball)
-3.) ./configure
-4.) make
-5.) sudo make install
-
-This will install the library into your machine's lib directory,
-the headers into include, and the example programs into bin.
-
-The configuration process assumes shared objects are searched for in
-/usr/local/lib. If this is not the case on your system, you can specify a
-search path at configuration time. For example:
-  ./configure LD_LIBRARY_PATH=/usr/local/lib
-
-------------------------------------------------------------
-
-Installing if you can compile GF-Complete, but you cannot install it:
-
-1.) Install GF-Complete.  Let's suppose the full path to GF-Complete is
-    in the environment variable  GFP
-2A.) On Linux, set the environment variable LD_LIBRARY_PATH so that it
-     includes $GFP/src/.libs
-2B.) On a mac, set the environment variable DYLD_LIBRARY_PATH so that it
-     includes $GFP/src/.libs
-2.) ./configure LDFLAGS=-L$GFP/src/.libs/ CPPFLAGS=-I$GFP/include
-3.) make
-
-The examples will be in the directory Examples.  The include files will
-be in the directory include, and the library will be called libJerasure.a
-in the directory src/.libs.
-
-------------------------------------------------------------
-
-As long as GF-Complete is installed, Jerasure 2.0 can be used just as previous
-versions.  There is no need to define custom Galois Fields.  Jerasure will
-determine the default field to use, if one is not specified.
-
-If you would like to explore a using a different Galois Field implementation,
-please see the manual.
-
-------------------------------------------------------------
-
-Testing GF-Complete
-
-If the GF-Complete tools are installed in /usr/local/bin
-
-  make check
-
-If the GF-Complete tools are installed elsewhere
-
-  make GF_COMPLETE_DIR=$(pwd)/../gf-complete/tools check
-
-To run some tests with valgrind
-
-  make VALGRIND='valgrind --tool=memcheck --quiet' \
-       GF_COMPLETE_DIR=$(pwd)/../gf-complete/tools \
-       check

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

-# The goal of this file is to map all the various variations of a given

-#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM

-##   supported by the other compilers which use the 'gcc' depmode.
-## - Using -M directly means running the compiler twice (even worse

-## This next piece of magic avoids the "deleted header file" problem.
-## The problem is that when a header file which appears in a .P file
-## is deleted, the dependency causes make to die (because there is
-## typically no way to rebuild the header).  We avoid this by adding
-## dummy dependencies for each header file.  Too bad gcc doesn't do
-## this for us directly.
-## Some versions of gcc put a space before the ':'.  On the theory
-## that the space means something, we add a space to the output as
-## well.  hp depmode also adds that space, but also prefixes the VPATH
-## to the object.  Take care to not repeat it in the output.

-   - Unescaped double quotes are removed from the input. Their only effect is
-     that within double quotes, space and tab are treated like normal
-     characters.
-   - Backslashes not followed by double quotes are not special.
-   - But 2*n+1 backslashes followed by a double quote become
-     n backslashes followed by a double quote (n >= 0):

-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX

-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR            user executables [EPREFIX/bin]

-
-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L if you have libraries in a
-              nonstandard directory 
-  LIBS        libraries to pass to the linker, e.g. -l
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I if
-              you have headers in a nonstandard directory 
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

-                              wm X wk bitmatrix (in GF(2)).  This is

-                              paper.
-
- - jerasure_dumb_bitmatrix_to_schedule turns a bitmatrix into a schedule
-                              using the straightforward algorithm -- just

-                              row of the matrix.
-
- - jerasure_smart_bitmatrix_to_schedule turns a bitmatrix into a schedule,
-                              but tries to use previous dot products to

-                              explained in the original Liberation code paper.
-
- - jerasure_generate_schedule_cache precalcalculate all the schedule for the

-# SYNOPSIS
-#
-#   AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
-#
-# DESCRIPTION
-#
-#   Check whether the given FLAG works with the current language's compiler
-#   or gives an error.  (Warnings, however, are ignored)
-#
-#   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
-#   success/failure.
-#
-#   If EXTRA-FLAGS is defined, it is added to the current language's default
-#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
-#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
-#   force the compiler to issue an error when a bad flag is given.
-#
-#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
-#
-#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
-#   macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

-# SYNOPSIS
-#
-#   AX_GCC_X86_AVX_XGETBV
-#
-# DESCRIPTION
-#
-#   On later x86 processors with AVX SIMD support, with gcc or a compiler
-#   that has a compatible syntax for inline assembly instructions, run a
-#   small program that executes the xgetbv instruction with input OP. This
-#   can be used to detect if the OS supports AVX instruction usage.
-#
-#   On output, the values of the eax and edx registers are stored as
-#   hexadecimal strings as "eax:edx" in the cache variable
-#   ax_cv_gcc_x86_avx_xgetbv.
-#
-#   If the xgetbv instruction fails (because you are running a
-#   cross-compiler, or because you are not using gcc, or because you are on
-#   a processor that doesn't have this instruction),
-#   ax_cv_gcc_x86_avx_xgetbv_OP is set to the string "unknown".
-#
-#   This macro mainly exists to be used in AX_EXT.

-#   AX_REQUIRE_DEFINED(MACRO)
-#
-# DESCRIPTION
-#
-#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
-#   been defined and thus are available for use.  This avoids random issues
-#   where a macro isn't expanded.  Instead the configure script emits a
-#   non-fatal:
-#
-#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
-#
-#   It's like AC_REQUIRE except it doesn't expand the required macro.
-#
-#   Here's an example:
-#
-#     AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])

-# serial 5 lt~obsolete.m4
-
-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else.  This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

-Installation Instructions
-*************************
-
-Copyright (C) 1994-1996, 1999-2002, 2004-2013 Free Software Foundation,
-Inc.
-
-   Copying and distribution of this file, with or without modification,
-are permitted in any medium without royalty provided the copyright
-notice and this notice are preserved.  This file is offered as-is,
-without warranty of any kind.
-
-Basic Installation
-==================
-
-   Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package.  The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package.  Some packages provide this
-`INSTALL' file but do not implement all of the features documented
-below.  The lack of an optional feature in a given package is not
-necessarily a bug.  More recommendations for GNU packages can be found
-in *note Makefile Conventions: (standards)Makefile Conventions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-   The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.
-
-     Running `configure' might take a while.  While running, it prints
-     some messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package, generally using the just-built uninstalled binaries.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.  When installing into a prefix owned by root, it is
-     recommended that the package be configured and built as a regular
-     user, and only the `make install' phase executed with root
-     privileges.
-
-  5. Optionally, type `make installcheck' to repeat any self-tests, but
-     this time using the binaries in their final installed location.
-     This target does not install anything.  Running this target as a
-     regular user, particularly if the prior `make install' required
-     root privileges, verifies that the installation completed
-     correctly.
-
-  6. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-  7. Often, you can also type `make uninstall' to remove the installed
-     files again.  In practice, not all packages have tested that
-     uninstallation works correctly, even though it is required by the
-     GNU Coding Standards.
-
-  8. Some packages, particularly those that use Automake, provide `make
-     distcheck', which can by used by developers to test that all other
-     targets like `make install' and `make uninstall' work correctly.
-     This target is generally not run by end users.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  Run `./configure --help'
-for details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.  This
-is known as a "VPATH" build.
-
-   With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
-   On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple `-arch' options to the
-compiler but only a single `-arch' option to the preprocessor.  Like
-this:
-
-     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CPP="gcc -E" CXXCPP="g++ -E"
-
-   This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the `lipo' tool if you have problems.
-
-Installation Names
-==================
-
-   By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc.  You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX', where PREFIX must be an
-absolute file name.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.  In general, the
-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 `${prefix}', must each be overridden at install
-time for the entire installation to be relocated.  The approach of
-makefile variable overrides for each directory variable is required by
-the GNU Coding Standards, and ideally causes no recompilation.
-However, some platforms have known limitations with the semantics of
-shared libraries that end up requiring recompilation when using this
-method, particularly noticeable in packages that use GNU Libtool.
-
-   The second method involves providing the `DESTDIR' variable.  For
-example, `make install DESTDIR=/alternate/directory' will prepend
-`/alternate/directory' before all installation names.  The approach of
-`DESTDIR' overrides is not required by the GNU Coding Standards, and
-does not work on platforms that have drive letters.  On the other hand,
-it does better at avoiding recompilation issues, and works well even
-when some directory options were not specified in terms of `${prefix}'
-at `configure' time.
-
-Optional Features
-=================
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-   Some packages offer the ability to configure how verbose the
-execution of `make' will be.  For these packages, running `./configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with `make V=1'; while running `./configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with `make V=0'.
-
-Particular systems
-==================
-
-   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
-CC is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
-     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
-   HP-UX `make' updates targets which have the same time stamps as
-their prerequisites, which makes it generally unusable when shipped
-generated files such as `configure' are involved.  Use GNU `make'
-instead.
-
-   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its `' header file.  The option `-nodtk' can be used as
-a workaround.  If GNU CC is not installed, it is therefore recommended
-to try
-
-     ./configure CC="cc"
-
-and if that doesn't work, try
-
-     ./configure CC="cc -nodtk"
-
-   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
-directory contains several dysfunctional programs; working variants of
-these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
-in your `PATH', put it _after_ `/usr/bin'.
-
-   On Haiku, software installed for all users goes in `/boot/common',
-not `/usr/local'.  It is recommended to use the following options:
-
-     ./configure --prefix=/boot/common
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS
-     KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-   Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf limitation.  Until the limitation is lifted, you can use
-this workaround:
-
-     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
-     Print a summary of all of the options to `configure', and exit.
-
-`--help=short'
-`--help=recursive'
-     Print a summary of the options unique to this package's
-     `configure', and exit.  The `short' variant lists options used
-     only in the top level, while the `recursive' variant lists options
-     also present in any nested packages.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--prefix=DIR'
-     Use DIR as the installation prefix.  *note Installation Names::
-     for more details, including other options available for fine-tuning
-     the installation locations.
-
-`--no-create'
-`-n'
-     Run the configure checks, but stop before creating any output
-     files.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

-liberasurecode
-==============
-
-liberasurecode is an Erasure Code API library written in C with pluggable Erasure Code backends.
-
-----
-
-Highlights
-==========
-
- * Unified Erasure Coding interface for common storage workloads.
-
- * Pluggable Erasure Code backends - As of v1.0, liberasurecode supports the following backends:
-
-      - 'Jerasure' - Erasure Coding library that supports Reed-Solomon, Cauchy backends [1]
-      - 'ISA-L' - Intel Storage Acceleration Library - SIMD accelerated Erasure Coding backends [2]
-      - 'SHSS' - NTT Lab Japan's hybrid Erasure Coding backend [4]
-      - 'Flat XOR HD' - built-in to liberasurecode, based on [3]
-      - 'NULL' template backend implemented to help future backend writers
-
-
- * True 'plugin' architecture - liberasurecode uses Dynamically Loaded (DL) libraries to realize a true 'plugin' architecture.  This also allows one to build liberasurecode indepdendent of the Erasure Code backend libraries.
-
- * Cross-platform - liberasurecode is known to work on Linux (Fedora/Debian flavors), Solaris, BSD and Darwin/Mac OS X.
-
- * Community support - Developed alongside Erasure Code authority Kevin Greenan, liberasurecode is an actively maintained open-source project with growing community involvement (Openstack Swift, Ceph, PyECLib).

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a

-# Configuration subroutine to validate and canonicalize a configuration type.

-# If it is invalid, we print an error message on stderr and exit with code 1.
-# Otherwise, we print the canonical config type on stdout and succeed.

-\`configure' configures liberasurecode 0.9.10 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-

-##   supported by the other compilers which use the 'gcc' depmode.
-## - Using -M directly means running the compiler twice (even worse

-## This next piece of magic avoids the "deleted header file" problem.
-## The problem is that when a header file which appears in a .P file
-## is deleted, the dependency causes make to die (because there is
-## typically no way to rebuild the header).  We avoid this by adding
-## dummy dependencies for each header file.  Too bad gcc doesn't do
-## this for us directly.
-## Some versions of gcc put a space before the ':'.  On the theory
-## that the space means something, we add a space to the output as
-## well.  hp depmode also adds that space, but also prefixes the VPATH
-## to the object.  Take care to not repeat it in the output.
