+Status
+======
+
+libffi-3.0.6 was released on July 17, 2008. Check the libffi web
+page for updates: <URL:http://sourceware.org/libffi/>.
+
+
+What is libffi?
+===============
+
+Compilers for high level languages generate code that follow certain
+conventions.  These conventions are necessary, in part, for separate
+compilation to work.  One such convention is the "calling convention".
+The "calling convention" is a set of assumptions made by the compiler
+about where function arguments will be found on entry to a function.
+A "calling convention" also specifies where the return value for a
+function is found.
+
+Some programs may not know at the time of compilation what arguments
+are to be passed to a function.  For instance, an interpreter may be
+told at run-time about the number and types of arguments used to call
+a given function.  Libffi can be used in such programs to provide a
+bridge from the interpreter program to compiled code.
+
+The libffi library provides a portable, high level programming
+interface to various calling conventions.  This allows a programmer to
+call any function specified by a call interface description at run
+time.
+
+FFI stands for Foreign Function Interface.  A foreign function
+interface is the popular name for the interface that allows code
+written in one language to call code written in another language.  The
+libffi library really only provides the lowest, machine dependent
+layer of a fully featured foreign function interface. A layer must
+exist above libffi that handles type conversions for values passed
+between the two languages.
+
+
+Supported Platforms
+===================
+
+Libffi has been ported to many different platforms, although this
+release was only tested on:
+
+     arm oabi linux
+     arm eabi linux
+     hppa linux
+     mips o32 linux (little endian)
+     powerpc darwin
+     powerpc64 linux
+     sparc solaris
+     sparc64 solaris
+     x86 cygwin
+     x86 darwin
+     x86 freebsd
+     x86 linux
+     x86 openbsd
+     x86-64 darwin
+     x86-64 linux
+     x86-64 OS X
+     x86-64 freebsd
+     
+Please send additional platform test results to
+libffi-discuss@sourceware.org.
+
+Installing libffi
+=================
+
+[Note: before actually performing any of these installation steps,
+ you may wish to read the "Platform Specific Notes" below.]
+
+First you must configure the distribution for your particular
+system. Go to the directory you wish to build libffi in and run the
+"configure" program found in the root directory of the libffi source
+distribution.
+
+You may want to tell configure where to install the libffi library and
+header files. To do that, use the --prefix configure switch.  Libffi
+will install under /usr/local by default. 
+
+If you want to enable extra run-time debugging checks use the the
+--enable-debug configure switch. This is useful when your program dies
+mysteriously while using libffi. 
+
+Another useful configure switch is --enable-purify-safety. Using this
+will add some extra code which will suppress certain warnings when you
+are using Purify with libffi. Only use this switch when using 
+Purify, as it will slow down the library.
+
+Configure has many other options. Use "configure --help" to see them all.
+
+Once configure has finished, type "make". Note that you must be using
+GNU make.  You can ftp GNU make from prep.ai.mit.edu:/pub/gnu.
+
+To ensure that libffi is working as advertised, type "make check".
+This will require that you have DejaGNU installed.
+
+To install the library and header files, type "make install".
+
+
+Platform Specific Notes
+=======================
+
+	MIPS - Irix 5.3 & 6.x
+	---------------------
+
+Irix 6.2 and better supports three different calling conventions: o32,
+n32 and n64. Currently, libffi only supports both o32 and n32 under
+Irix 6.x, but only o32 under Irix 5.3. Libffi will automatically be
+configured for whichever calling convention it was built for.
+
+By default, the configure script will try to build libffi with the GNU
+development tools. To build libffi with the SGI development tools, set
+the environment variable CC to either "cc -32" or "cc -n32" before
+running configure under Irix 6.x (depending on whether you want an o32
+or n32 library), or just "cc" for Irix 5.3.
+
+With the n32 calling convention, when returning structures smaller
+than 16 bytes, be sure to provide an RVALUE that is 8 byte aligned.
+Here's one way of forcing this:
+
+	double struct_storage[2];
+	my_small_struct *s = (my_small_struct *) struct_storage;  
+	/* Use s for RVALUE */
+
+If you don't do this you are liable to get spurious bus errors. 
+
+"long long" values are not supported yet.
+
+You must use GNU Make to build libffi on SGI platforms.
+
+
+	PowerPC System V ABI
+	--------------------
+
+There are two `System V ABI's which libffi implements for PowerPC.
+They differ only in how small structures are returned from functions.
+
+In the FFI_SYSV version, structures that are 8 bytes or smaller are
+returned in registers.  This is what GCC does when it is configured
+for solaris, and is what the System V ABI I have (dated September
+1995) says.
+
+In the FFI_GCC_SYSV version, all structures are returned the same way:
+by passing a pointer as the first argument to the function.  This is
+what GCC does when it is configured for linux or a generic sysv
+target.
+
+EGCS 1.0.1 (and probably other versions of EGCS/GCC) also has a
+inconsistency with the SysV ABI: When a procedure is called with many
+floating-point arguments, some of them get put on the stack.  They are
+all supposed to be stored in double-precision format, even if they are
+only single-precision, but EGCS stores single-precision arguments as
+single-precision anyway.  This causes one test to fail (the `many
+arguments' test).
+

+# 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.

+# is unlikely to handle the host's binaries.

+# STRIPPROG with the value of the STRIP variable (set by the user).

+\`configure' configures libffi 3.0.6 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'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+@chapter What is libffi?
+
+Compilers for high level languages generate code that follow certain
+conventions.  These conventions are necessary, in part, for separate
+compilation to work.  One such convention is the @dfn{calling
+convention}.  The calling convention is a set of assumptions made by
+the compiler about where function arguments will be found on entry to
+a function.  A calling convention also specifies where the return
+value for a function is found.  The calling convention is also
+sometimes called the @dfn{ABI} or @dfn{Application Binary Interface}.
+@cindex calling convention
+@cindex ABI
+@cindex Application Binary Interface
+
+Some programs may not know at the time of compilation what arguments
+are to be passed to a function.  For instance, an interpreter may be
+told at run-time about the number and types of arguments used to call
+a given function.  @samp{Libffi} can be used in such programs to
+provide a bridge from the interpreter program to compiled code.
+
+The @samp{libffi} library provides a portable, high level programming
+interface to various calling conventions.  This allows a programmer to
+call any function specified by a call interface description at run
+time.
+
+@acronym{FFI} stands for Foreign Function Interface.  A foreign
+function interface is the popular name for the interface that allows
+code written in one language to call code written in another language.
+The @samp{libffi} library really only provides the lowest, machine
+dependent layer of a fully featured foreign function interface.  A
+layer must exist above @samp{libffi} that handles type conversions for
+values passed between the two languages.

+@node The Basics
+@section The Basics
+
+@samp{Libffi} assumes that you have a pointer to the function you wish
+to call and that you know the number and types of arguments to pass
+it, as well as the return type of the function.
+
+The first thing you must do is create an @code{ffi_cif} object that
+matches the signature of the function you wish to call.  This is a
+separate step because it is common to make multiple calls using a
+single @code{ffi_cif}.  The @dfn{cif} in @code{ffi_cif} stands for
+Call InterFace.  To prepare a call interface object, use the function
+@code{ffi_prep_cif}.
+@cindex cif
+
+@findex ffi_prep_cif
+@defun ffi_status ffi_prep_cif (ffi_cif *@var{cif}, ffi_abi @var{abi}, unsigned int @var{nargs}, ffi_type *@var{rtype}, ffi_type **@var{argtypes})
+This initializes @var{cif} according to the given parameters.
+
+@var{abi} is the ABI to use; normally @code{FFI_DEFAULT_ABI} is what
+you want.  @ref{Multiple ABIs} for more information.
+
+@var{nargs} is the number of arguments that this function accepts.
+@samp{libffi} does not yet handle varargs functions; see @ref{Missing
+Features} for more information.
+
+@var{rtype} is a pointer to an @code{ffi_type} structure that
+describes the return type of the function.  @xref{Types}.
+
+@var{argtypes} is a vector of @code{ffi_type} pointers.
+@var{argtypes} must have @var{nargs} elements.  If @var{nargs} is 0,
+this argument is ignored.
+
+@code{ffi_prep_cif} returns a @code{libffi} status code, of type
+@code{ffi_status}.  This will be either @code{FFI_OK} if everything
+worked properly; @code{FFI_BAD_TYPEDEF} if one of the @code{ffi_type}
+objects is incorrect; or @code{FFI_BAD_ABI} if the @var{abi} parameter
+is invalid.
+@end defun
+
+
+To call a function using an initialized @code{ffi_cif}, use the
+@code{ffi_call} function:
+
+@findex ffi_call
+@defun void ffi_call (ffi_cif *@var{cif}, void *@var{fn}, void *@var{rvalue}, void **@var{avalues})
+This calls the function @var{fn} according to the description given in
+@var{cif}.  @var{cif} must have already been prepared using
+@code{ffi_prep_cif}.
+
+@var{rvalue} is a pointer to a chunk of memory that will hold the
+result of the function call.  This must be large enough to hold the
+result and must be suitably aligned; it is the caller's responsibility
+to ensure this.  If @var{cif} declares that the function returns
+@code{void} (using @code{ffi_type_void}), then @var{rvalue} is
+ignored.  If @var{rvalue} is @samp{NULL}, then the return value is
+discarded.
+
+@var{avalues} is a vector of @code{void *} pointers that point to the
+memory locations holding the argument values for a call.  If @var{cif}
+declares that the function has no arguments (i.e., @var{nargs} was 0),
+then @var{avalues} is ignored.
+@end defun
+
+
+@node Simple Example
+@section Simple Example
+
+Here is a trivial example that calls @code{puts} a few times.
+
+@example
+#include <stdio.h>
+#include <ffi.h>
+
+int main()
+@{
+  ffi_cif cif;
+  ffi_type *args[1];

+  
+  /* Initialize the cif */
+  if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, 
+		       &ffi_type_uint, args) == FFI_OK)
+    @{
+      s = "Hello World!";
+      ffi_call(&cif, puts, &rc, values);
+      /* rc now holds the result of the call to puts */
+      
+      /* values holds a pointer to the function's arg, so to 
+         call puts() again all we need to do is change the 
+         value of s */

+@item ffi_type_sint64
+@tindex ffi_type_sint64
+A signed, 64-bit integer type.
+
+@item ffi_type_float
+@tindex ffi_type_float
+The C @code{float} type.
+
+@item ffi_type_double
+@tindex ffi_type_double
+The C @code{double} type.
+
+@item ffi_type_uchar
+@tindex ffi_type_uchar
+The C @code{unsigned char} type.
+
+@item ffi_type_schar
+@tindex ffi_type_schar
+The C @code{signed char} type.  (Note that there is not an exact
+equivalent to the C @code{char} type in @code{libffi}; ordinarily you
+should either use @code{ffi_type_schar} or @code{ffi_type_uchar}
+depending on whether @code{char} is signed.)
+
+@item ffi_type_ushort
+@tindex ffi_type_ushort
+The C @code{unsigned short} type.
+
+@item ffi_type_sshort
+@tindex ffi_type_sshort
+The C @code{short} type.
+
+@item ffi_type_uint

+@item ffi_type_slong
+@tindex ffi_type_slong
+The C @code{long} type.
+
+@item ffi_type_longdouble
+@tindex ffi_type_longdouble
+On platforms that have a C @code{long double} type, this is defined.
+On other platforms, it is not.
+
+@item ffi_type_pointer
+@tindex ffi_type_pointer
+A generic @code{void *} pointer.  You should use this for all
+pointers, regardless of their real type.
+@end table
+
+Each of these is of type @code{ffi_type}, so you must take the address
+when passing to @code{ffi_prep_cif}.

+@node Structures
+@subsection Structures
+
+Although @samp{libffi} has no special support for unions or
+bit-fields, it is perfectly happy passing structures back and forth.
+You must first describe the structure to @samp{libffi} by creating a

+
+@item unsigned short alignment
+This is set by @code{libffi}; you should initialize it to zero.

+@node Type Example
+@subsection Type Example
+
+The following example initializes a @code{ffi_type} object
+representing the @code{tm} struct from Linux's @file{time.h}.
+
+Here is how the struct is defined:
+
+@example
+struct tm @{
+    int tm_sec;
+    int tm_min;
+    int tm_hour;
+    int tm_mday;
+    int tm_mon;
+    int tm_year;
+    int tm_wday;
+    int tm_yday;
+    int tm_isdst;
+    /* Those are for future use. */
+    long int __tm_gmtoff__;
+    __const char *__tm_zone__;
+@};
+@end example
+
+Here is the corresponding code to describe this struct to
+@code{libffi}:
+
+@example
+    @{
+      ffi_type tm_type;
+      ffi_type *tm_type_elements[12];
+      int i;
+
+      tm_type.size = tm_type.alignment = 0;
+      tm_type.elements = &tm_type_elements;
+    
+      for (i = 0; i < 9; i++)
+          tm_type_elements[i] = &ffi_type_sint;
+
+      tm_type_elements[9] = &ffi_type_slong;
+      tm_type_elements[10] = &ffi_type_pointer;
+      tm_type_elements[11] = NULL;
+
+      /* tm_type can now be used to represent tm argument types and
+	 return types for ffi_prep_cif() */
+    @}

+@node Multiple ABIs
+@section Multiple ABIs
+
+A given platform may provide multiple different ABIs at once.  For
+instance, the x86 platform has both @samp{stdcall} and @samp{fastcall}
+functions.
+
+@code{libffi} provides some support for this.  However, this is
+necessarily platform-specific.
+
+@c FIXME: document the platforms
+
+@node The Closure API
+@section The Closure API
+
+@code{libffi} also provides a way to write a generic function -- a
+function that can accept and decode any combination of arguments.
+This can be useful when writing an interpreter, or to provide wrappers
+for arbitrary functions.
+
+This facility is called the @dfn{closure API}.  Closures are not
+supported on all platforms; you can check the @code{FFI_CLOSURES}
+define to determine whether they are supported on the current
+platform.
+@cindex closures
+@cindex closure API
+@findex FFI_CLOSURES
+
+Because closures work by assembling a tiny function at runtime, they
+require special allocation on platforms that have a non-executable
+heap.  Memory management for closures is handled by a pair of
+functions:
+
+@findex ffi_closure_alloca
+@defun void *ffi_closure_alloc (size_t @var{size}, void **@var{code})
+Allocate a chunk of memory holding @var{size} bytes.  This returns a
+pointer to the writable address, and sets *@var{code} to the
+corresponding executable address.
+
+@var{size} should be sufficient to hold a @code{ffi_closure} object.
+@end defun
+
+@findex ffi_closure_free
+@defun void ffi_closure_free (void *@var{writable})
+Free memory allocated using @code{ffi_closure_alloc}.  The argument is
+the writable address that was returned.
+@end defun
+
+
+Once you have allocated the memory for a closure, you must construct a
+@code{ffi_cif} describing the function call.  Finally you can prepare
+the closure function:
+
+@findex ffi_prep_closure_loc
+@defun ffi_status ffi_prep_closure_loc (ffi_closure *@var{closure}, ffi_cif *@var{cif}, void (*@var{fun}) (ffi_cif *@var{cif}, void *@var{ret}, void **@var{args}, void *@var{user_data}), void *@var{user_data}, void *@var{codeloc})
+Prepare a closure function.
+
+@var{closure} is the address of a @code{ffi_closure} object; this is
+the writable address returned by @code{ffi_closure_alloc}.
+
+@var{cif} is the @code{ffi_cif} describing the function parameters.
+
+@var{user_data} is an arbitrary datum that is passed, uninterpreted,
+to your closure function.
+
+@var{codeloc} is the executable address returned by
+@code{ffi_closure_alloc}.
+
+@var{fun} is the function which will be called when the closure is
+invoked.  It is called with the arguments:
+@table @var
+@item cif
+The @code{ffi_cif} passed to @code{ffi_prep_closure_loc}.
+
+@item ret
+A pointer to the memory used for the function's return value.
+@var{fun} must fill this, unless the function is declared as returning
+@code{void}.
+@c FIXME: is this NULL for void-returning functions?
+
+@item args
+A vector of pointers to memory holding the arguments to the function.
+
+@item user_data
+The same @var{user_data} that was passed to
+@code{ffi_prep_closure_loc}.
+@end table
+
+@code{ffi_prep_closure_loc} will return @code{FFI_OK} if everything
+went ok, and something else on error.
+@c FIXME: what?
+
+After calling @code{ffi_prep_closure_loc}, you can cast @var{codeloc}
+to the appropriate pointer-to-function type.
+@end defun
+
+@c FIXME: example
+
+You may see old code referring to @code{ffi_prep_closure}.  This
+function is deprecated, as it cannot handle the need for separate
+writable and executable addresses.
+
+
+@node Missing Features
+@chapter Missing Features
+
+@code{libffi} is missing a few features.  We welcome patches to add
+support for these.
+
+@itemize @bullet
+@item
+There is no support for calling varargs functions.  This may work on
+some platforms, depending on how the ABI is defined, but it is not
+reliable.
+
+@item
+There is no support for bit fields in structures.
+
+@item
+The closure API is
+
+@item
+The ``raw'' API is undocumented.

+   The basic API is described in the README file.
+
+   The raw API is designed to bypass some of the argument packing
+   and unpacking on architectures for which it can be avoided.
+
+   The closure API allows interpreted functions to be packaged up
+   inside a C function pointer, so that they can be called as C functions,
+   with no understanding on the client side that they are interpreted.
+   It can also be used in other cases in which it is necessary to package
+   up a user specified parameter and a function pointer as a single
+   function pointer.
+
+   The closure API must be implemented in order to get its functionality,
+   e.g. for use by gij.  Routines are provided to emulate the raw API
+   if the underlying platform doesn't allow faster implementation.
+
+   More details on the raw and cloure API can be found in:
+
+   http://gcc.gnu.org/ml/java/1999-q3/msg00138.html
+
+   and
+
+   http://gcc.gnu.org/ml/java/1999-q3/msg00174.html

+   The basic API is described in the README file.
+
+   The raw API is designed to bypass some of the argument packing
+   and unpacking on architectures for which it can be avoided.
+
+   The closure API allows interpreted functions to be packaged up
+   inside a C function pointer, so that they can be called as C functions,
+   with no understanding on the client side that they are interpreted.
+   It can also be used in other cases in which it is necessary to package
+   up a user specified parameter and a function pointer as a single
+   function pointer.
+
+   The closure API must be implemented in order to get its functionality,
+   e.g. for use by gij.  Routines are provided to emulate the raw API
+   if the underlying platform doesn't allow faster implementation.
+
+   More details on the raw and cloure API can be found in:
+
+   http://gcc.gnu.org/ml/java/1999-q3/msg00138.html
+
+   and
+
+   http://gcc.gnu.org/ml/java/1999-q3/msg00174.html

+#
+# Here are a set of rules to help you update your library version
+# information:
+# 
+# 1. Start with version information of `0:0:0' for each libtool library.
+#
+# 2. Update the version information only immediately before a public
+#    release of your software. More frequent updates are unnecessary,
+#    and only guarantee that the current interface number gets larger
+#    faster.
+#
+# 3. If the library source code has changed at all since the last
+#    update, then increment revision (`c:r:a' becomes `c:r+1:a').
+#
+# 4. If any interfaces have been added, removed, or changed since the
+#    last update, increment current, and set revision to 0.
+#
+# 5. If any interfaces have been added since the last public release,
+#    then increment age.
+#
+# 6. If any interfaces have been removed since the last public
+#    release, then set age to 0.

+.Sh DESCRIPTION
+The
+.Nm ffi_call
+function provides a simple mechanism for invoking a function without
+requiring knowledge of the function's interface at compile time.
+.Fa fn
+is called with the values retrieved from the pointers in the
+.Fa avalue
+array. The return value from
+.Fa fn
+is placed in storage pointed to by
+.Fa rvalue .
+.Fa cif
+contains information describing the data types, sizes and alignments of the
+arguments to and return value from
+.Fa fn ,
+and must be initialized with
+.Nm ffi_prep_cif
+before it is used with
+.Nm ffi_call .
+.Pp
+.Fa rvalue
+must point to storage that is sizeof(long) or larger. For smaller
+return value sizes, the
+.Nm ffi_arg
+or
+.Nm ffi_sarg
+integral type must be used to hold
+the return value.

+* Version 2.8.3 Thu Sep 22 11:16:15 2005  Doug Lea  (dl at gee)
+
+   Note: There may be an updated version of this malloc obtainable at
+           ftp://gee.cs.oswego.edu/pub/misc/malloc.c
+         Check before installing!
+
+* Quickstart
+
+  This library is all in one file to simplify the most common usage:
+  ftp it, compile it (-O3), and link it into another program. All of
+  the compile-time options default to reasonable values for use on
+  most platforms.  You might later want to step through various
+  compile-time and dynamic tuning options.
+
+  For convenience, an include file for code using this malloc is at:
+     ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.3.h
+  You don't really need this .h file unless you call functions not
+  defined in your system include files.  The .h file contains only the
+  excerpts from this file needed for using this malloc on ANSI C/C++
+  systems, so long as you haven't changed compile-time options about
+  naming and tuning parameters.  If you do, then you can create your
+  own malloc.h that does include all settings by cutting at the point
+  indicated below. Note that you may already by default be using a C
+  library containing a malloc that is based on some version of this
+  malloc (for example in linux). You might still want to use the one
+  in this file to customize settings or to avoid overheads associated
+  with library versions.
+
+* Vital statistics:
+
+  Supported pointer/size_t representation:       4 or 8 bytes
+       size_t MUST be an unsigned type of the same width as
+       pointers. (If you are using an ancient system that declares
+       size_t as a signed type, or need it to be a different width
+       than pointers, you can use a previous release of this malloc
+       (e.g. 2.7.2) supporting these.)
+
+  Alignment:                                     8 bytes (default)
+       This suffices for nearly all current machines and C compilers.
+       However, you can define MALLOC_ALIGNMENT to be wider than this
+       if necessary (up to 128bytes), at the expense of using more space.
+
+  Minimum overhead per allocated chunk:   4 or  8 bytes (if 4byte sizes)
+                                          8 or 16 bytes (if 8byte sizes)
+       Each malloced chunk has a hidden word of overhead holding size
+       and status information, and additional cross-check word
+       if FOOTERS is defined.
+
+  Minimum allocated size: 4-byte ptrs:  16 bytes    (including overhead)
+                          8-byte ptrs:  32 bytes    (including overhead)
+
+       Even a request for zero bytes (i.e., malloc(0)) returns a
+       pointer to something of the minimum allocatable size.
+       The maximum overhead wastage (i.e., number of extra bytes
+       allocated than were requested in malloc) is less than or equal
+       to the minimum size, except for requests >= mmap_threshold that
+       are serviced via mmap(), where the worst case wastage is about
+       32 bytes plus the remainder from a system page (the minimal
+       mmap unit); typically 4096 or 8192 bytes.
+
+  Security: static-safe; optionally more or less
+       The "security" of malloc refers to the ability of malicious
+       code to accentuate the effects of errors (for example, freeing
+       space that is not currently malloc'ed or overwriting past the
+       ends of chunks) in code that calls malloc.  This malloc
+       guarantees not to modify any memory locations below the base of
+       heap, i.e., static variables, even in the presence of usage
+       errors.  The routines additionally detect most improper frees
+       and reallocs.  All this holds as long as the static bookkeeping
+       for malloc itself is not corrupted by some other means.  This
+       is only one aspect of security -- these checks do not, and
+       cannot, detect all possible programming errors.
+
+       If FOOTERS is defined nonzero, then each allocated chunk
+       carries an additional check word to verify that it was malloced
+       from its space.  These check words are the same within each
+       execution of a program using malloc, but differ across
+       executions, so externally crafted fake chunks cannot be
+       freed. This improves security by rejecting frees/reallocs that
+       could corrupt heap memory, in addition to the checks preventing
+       writes to statics that are always on.  This may further improve
+       security at the expense of time and space overhead.  (Note that
+       FOOTERS may also be worth using with MSPACES.)
+
+       By default detected errors cause the program to abort (calling
+       "abort()"). You can override this to instead proceed past
+       errors by defining PROCEED_ON_ERROR.  In this case, a bad free
+       has no effect, and a malloc that encounters a bad address
+       caused by user overwrites will ignore the bad address by
+       dropping pointers and indices to all known memory. This may
+       be appropriate for programs that should continue if at all
+       possible in the face of programming errors, although they may
+       run out of memory because dropped memory is never reclaimed.
+
+       If you don't like either of these options, you can define
+       CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything
+       else. And if if you are sure that your program using malloc has
+       no errors or vulnerabilities, you can define INSECURE to 1,
+       which might (or might not) provide a small performance improvement.
+
+  Thread-safety: NOT thread-safe unless USE_LOCKS defined
+       When USE_LOCKS is defined, each public call to malloc, free,
+       etc is surrounded with either a pthread mutex or a win32
+       spinlock (depending on WIN32). This is not especially fast, and
+       can be a major bottleneck.  It is designed only to provide
+       minimal protection in concurrent environments, and to provide a
+       basis for extensions.  If you are using malloc in a concurrent
+       program, consider instead using ptmalloc, which is derived from
+       a version of this malloc. (See http://www.malloc.de).
+
+  System requirements: Any combination of MORECORE and/or MMAP/MUNMAP
+       This malloc can use unix sbrk or any emulation (invoked using
+       the CALL_MORECORE macro) and/or mmap/munmap or any emulation
+       (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system
+       memory.  On most unix systems, it tends to work best if both
+       MORECORE and MMAP are enabled.  On Win32, it uses emulations
+       based on VirtualAlloc. It also uses common C library functions
+       like memset.
+
+  Compliance: I believe it is compliant with the Single Unix Specification
+       (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably
+       others as well.
+
+* Overview of algorithms
+
+  This is not the fastest, most space-conserving, most portable, or
+  most tunable malloc ever written. However it is among the fastest
+  while also being among the most space-conserving, portable and
+  tunable.  Consistent balance across these factors results in a good
+  general-purpose allocator for malloc-intensive programs.
+
+  In most ways, this malloc is a best-fit allocator. Generally, it
+  chooses the best-fitting existing chunk for a request, with ties
+  broken in approximately least-recently-used order. (This strategy
+  normally maintains low fragmentation.) However, for requests less
+  than 256bytes, it deviates from best-fit when there is not an
+  exactly fitting available chunk by preferring to use space adjacent
+  to that used for the previous small request, as well as by breaking
+  ties in approximately most-recently-used order. (These enhance
+  locality of series of small allocations.)  And for very large requests
+  (>= 256Kb by default), it relies on system memory mapping
+  facilities, if supported.  (This helps avoid carrying around and
+  possibly fragmenting memory used only for large chunks.)
+
+  All operations (except malloc_stats and mallinfo) have execution
+  times that are bounded by a constant factor of the number of bits in
+  a size_t, not counting any clearing in calloc or copying in realloc,
+  or actions surrounding MORECORE and MMAP that have times
+  proportional to the number of non-contiguous regions returned by
+  system allocation routines, which is often just 1.
+
+  The implementation is not very modular and seriously overuses
+  macros. Perhaps someday all C compilers will do as good a job
+  inlining modular code as can now be done by brute-force expansion,
+  but now, enough of them seem not to.
+
+  Some compilers issue a lot of warnings about code that is
+  dead/unreachable only on some platforms, and also about intentional
+  uses of negation on unsigned types. All known cases of each can be
+  ignored.
+
+  For a longer but out of date high-level description, see
+     http://gee.cs.oswego.edu/dl/html/malloc.html
+
+* MSPACES
+  If MSPACES is defined, then in addition to malloc, free, etc.,
+  this file also defines mspace_malloc, mspace_free, etc. These
+  are versions of malloc routines that take an "mspace" argument
+  obtained using create_mspace, to control all internal bookkeeping.
+  If ONLY_MSPACES is defined, only these versions are compiled.
+  So if you would like to use this allocator for only some allocations,
+  and your system malloc for others, you can compile with
+  ONLY_MSPACES and then do something like...
+    static mspace mymspace = create_mspace(0,0); // for example
+    #define mymalloc(bytes)  mspace_malloc(mymspace, bytes)
+
+  (Note: If you only need one instance of an mspace, you can instead
+  use "USE_DL_PREFIX" to relabel the global malloc.)
+
+  You can similarly create thread-local allocators by storing
+  mspaces as thread-locals. For example:
+    static __thread mspace tlms = 0;
+    void*  tlmalloc(size_t bytes) {
+      if (tlms == 0) tlms = create_mspace(0, 0);
+      return mspace_malloc(tlms, bytes);
+    }
+    void  tlfree(void* mem) { mspace_free(tlms, mem); }
+
+  Unless FOOTERS is defined, each mspace is completely independent.
+  You cannot allocate from one and free to another (although
+  conformance is only weakly checked, so usage errors are not always
+  caught). If FOOTERS is defined, then each chunk carries around a tag
+  indicating its originating mspace, and frees are directed to their
+  originating spaces.
+
+ -------------------------  Compile-time options ---------------------------
+
+Be careful in setting #define values for numerical constants of type
+size_t. On some systems, literal values are not automatically extended
+to size_t precision unless they are explicitly casted.
+
+WIN32                    default: defined if _WIN32 defined
+  Defining WIN32 sets up defaults for MS environment and compilers.
+  Otherwise defaults are for unix.
+
+MALLOC_ALIGNMENT         default: (size_t)8
+  Controls the minimum alignment for malloc'ed chunks.  It must be a
+  power of two and at least 8, even on machines for which smaller
+  alignments would suffice. It may be defined as larger than this
+  though. Note however that code and data structures are optimized for
+  the case of 8-byte alignment.
+
+MSPACES                  default: 0 (false)
+  If true, compile in support for independent allocation spaces.
+  This is only supported if HAVE_MMAP is true.
+
+ONLY_MSPACES             default: 0 (false)
+  If true, only compile in mspace versions, not regular versions.
+
+USE_LOCKS                default: 0 (false)
+  Causes each call to each public routine to be surrounded with
+  pthread or WIN32 mutex lock/unlock. (If set true, this can be
+  overridden on a per-mspace basis for mspace versions.)
+
+FOOTERS                  default: 0
+  If true, provide extra checking and dispatching by placing
+  information in the footers of allocated chunks. This adds
+  space and time overhead.
+
+INSECURE                 default: 0
+  If true, omit checks for usage errors and heap space overwrites.
+
+USE_DL_PREFIX            default: NOT defined
+  Causes compiler to prefix all public routines with the string 'dl'.
+  This can be useful when you only want to use this malloc in one part
+  of a program, using your regular system malloc elsewhere.
+
+ABORT                    default: defined as abort()
+  Defines how to abort on failed checks.  On most systems, a failed
+  check cannot die with an "assert" or even print an informative
+  message, because the underlying print routines in turn call malloc,
+  which will fail again.  Generally, the best policy is to simply call
+  abort(). It's not very useful to do more than this because many
+  errors due to overwriting will show up as address faults (null, odd
+  addresses etc) rather than malloc-triggered checks, so will also
+  abort.  Also, most compilers know that abort() does not return, so
+  can better optimize code conditionally calling it.
+
+PROCEED_ON_ERROR           default: defined as 0 (false)
+  Controls whether detected bad addresses cause them to bypassed
+  rather than aborting. If set, detected bad arguments to free and
+  realloc are ignored. And all bookkeeping information is zeroed out
+  upon a detected overwrite of freed heap space, thus losing the
+  ability to ever return it from malloc again, but enabling the
+  application to proceed. If PROCEED_ON_ERROR is defined, the
+  static variable malloc_corruption_error_count is compiled in
+  and can be examined to see if errors have occurred. This option
+  generates slower code than the default abort policy.
+
+DEBUG                    default: NOT defined
+  The DEBUG setting is mainly intended for people trying to modify
+  this code or diagnose problems when porting to new platforms.
+  However, it may also be able to better isolate user errors than just
+  using runtime checks.  The assertions in the check routines spell
+  out in more detail the assumptions and invariants underlying the
+  algorithms.  The checking is fairly extensive, and will slow down
+  execution noticeably. Calling malloc_stats or mallinfo with DEBUG
+  set will attempt to check every non-mmapped allocated and free chunk
+  in the course of computing the summaries.
+
+ABORT_ON_ASSERT_FAILURE   default: defined as 1 (true)
+  Debugging assertion failures can be nearly impossible if your
+  version of the assert macro causes malloc to be called, which will
+  lead to a cascade of further failures, blowing the runtime stack.
+  ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(),
+  which will usually make debugging easier.
+
+MALLOC_FAILURE_ACTION     default: sets errno to ENOMEM, or no-op on win32
+  The action to take before "return 0" when malloc fails to be able to
+  return memory because there is none available.
+
+HAVE_MORECORE             default: 1 (true) unless win32 or ONLY_MSPACES
+  True if this system supports sbrk or an emulation of it.
+
+MORECORE                  default: sbrk
+  The name of the sbrk-style system routine to call to obtain more
+  memory.  See below for guidance on writing custom MORECORE
+  functions. The type of the argument to sbrk/MORECORE varies across
+  systems.  It cannot be size_t, because it supports negative
+  arguments, so it is normally the signed type of the same width as
+  size_t (sometimes declared as "intptr_t").  It doesn't much matter
+  though. Internally, we only call it with arguments less than half
+  the max value of a size_t, which should work across all reasonable
+  possibilities, although sometimes generating compiler warnings.  See
+  near the end of this file for guidelines for creating a custom
+  version of MORECORE.
+
+MORECORE_CONTIGUOUS       default: 1 (true)
+  If true, take advantage of fact that consecutive calls to MORECORE
+  with positive arguments always return contiguous increasing
+  addresses.  This is true of unix sbrk. It does not hurt too much to
+  set it true anyway, since malloc copes with non-contiguities.
+  Setting it false when definitely non-contiguous saves time
+  and possibly wasted space it would take to discover this though.
+
+MORECORE_CANNOT_TRIM      default: NOT defined
+  True if MORECORE cannot release space back to the system when given
+  negative arguments. This is generally necessary only if you are
+  using a hand-crafted MORECORE function that cannot handle negative
+  arguments.
+
+HAVE_MMAP                 default: 1 (true)
+  True if this system supports mmap or an emulation of it.  If so, and
+  HAVE_MORECORE is not true, MMAP is used for all system
+  allocation. If set and HAVE_MORECORE is true as well, MMAP is
+  primarily used to directly allocate very large blocks. It is also
+  used as a backup strategy in cases where MORECORE fails to provide
+  space from system. Note: A single call to MUNMAP is assumed to be
+  able to unmap memory that may have be allocated using multiple calls
+  to MMAP, so long as they are adjacent.
+
+HAVE_MREMAP               default: 1 on linux, else 0
+  If true realloc() uses mremap() to re-allocate large blocks and
+  extend or shrink allocation spaces.
+
+MMAP_CLEARS               default: 1 on unix
+  True if mmap clears memory so calloc doesn't need to. This is true
+  for standard unix mmap using /dev/zero.
+
+USE_BUILTIN_FFS            default: 0 (i.e., not used)
+  Causes malloc to use the builtin ffs() function to compute indices.
+  Some compilers may recognize and intrinsify ffs to be faster than the
+  supplied C version. Also, the case of x86 using gcc is special-cased
+  to an asm instruction, so is already as fast as it can be, and so
+  this setting has no effect. (On most x86s, the asm version is only
+  slightly faster than the C version.)
+
+malloc_getpagesize         default: derive from system includes, or 4096.
+  The system page size. To the extent possible, this malloc manages
+  memory from the system in page-size units.  This may be (and
+  usually is) a function rather than a constant. This is ignored
+  if WIN32, where page size is determined using getSystemInfo during
+  initialization.
+
+USE_DEV_RANDOM             default: 0 (i.e., not used)
+  Causes malloc to use /dev/random to initialize secure magic seed for
+  stamping footers. Otherwise, the current time is used.
+
+NO_MALLINFO                default: 0
+  If defined, don't compile "mallinfo". This can be a simple way
+  of dealing with mismatches between system declarations and
+  those in this file.
+
+MALLINFO_FIELD_TYPE        default: size_t
+  The type of the fields in the mallinfo struct. This was originally
+  defined as "int" in SVID etc, but is more usefully defined as
+  size_t. The value is used only if  HAVE_USR_INCLUDE_MALLOC_H is not set
+
+REALLOC_ZERO_BYTES_FREES    default: not defined
+  This should be set if a call to realloc with zero bytes should 
+  be the same as a call to free. Some people think it should. Otherwise, 
+  since this malloc returns a unique pointer for malloc(0), so does 
+  realloc(p, 0).
+
+LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H
+LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H,  LACKS_ERRNO_H
+LACKS_STDLIB_H                default: NOT defined unless on WIN32
+  Define these if your system does not have these header files.
+  You might need to manually insert some of the declarations they provide.
+
+DEFAULT_GRANULARITY        default: page size if MORECORE_CONTIGUOUS,
+                                system_info.dwAllocationGranularity in WIN32,
+                                otherwise 64K.
+      Also settable using mallopt(M_GRANULARITY, x)
+  The unit for allocating and deallocating memory from the system.  On
+  most systems with contiguous MORECORE, there is no reason to
+  make this more than a page. However, systems with MMAP tend to
+  either require or encourage larger granularities.  You can increase
+  this value to prevent system allocation functions to be called so
+  often, especially if they are slow.  The value must be at least one
+  page and must be a power of two.  Setting to 0 causes initialization
+  to either page size or win32 region size.  (Note: In previous
+  versions of malloc, the equivalent of this option was called
+  "TOP_PAD")
+
+DEFAULT_TRIM_THRESHOLD    default: 2MB
+      Also settable using mallopt(M_TRIM_THRESHOLD, x)
+  The maximum amount of unused top-most memory to keep before
+  releasing via malloc_trim in free().  Automatic trimming is mainly
+  useful in long-lived programs using contiguous MORECORE.  Because
+  trimming via sbrk can be slow on some systems, and can sometimes be
+  wasteful (in cases where programs immediately afterward allocate
+  more large chunks) the value should be high enough so that your
+  overall system performance would improve by releasing this much
+  memory.  As a rough guide, you might set to a value close to the
+  average size of a process (program) running on your system.
+  Releasing this much memory would allow such a process to run in
+  memory.  Generally, it is worth tuning trim thresholds when a
+  program undergoes phases where several large chunks are allocated
+  and released in ways that can reuse each other's storage, perhaps
+  mixed with phases where there are no such chunks at all. The trim
+  value must be greater than page size to have any useful effect.  To
+  disable trimming completely, you can set to MAX_SIZE_T. Note that the trick
+  some people use of mallocing a huge space and then freeing it at
+  program startup, in an attempt to reserve system memory, doesn't
+  have the intended effect under automatic trimming, since that memory
+  will immediately be returned to the system.
+
+DEFAULT_MMAP_THRESHOLD       default: 256K
+      Also settable using mallopt(M_MMAP_THRESHOLD, x)
+  The request size threshold for using MMAP to directly service a
+  request. Requests of at least this size that cannot be allocated
+  using already-existing space will be serviced via mmap.  (If enough
+  normal freed space already exists it is used instead.)  Using mmap
+  segregates relatively large chunks of memory so that they can be
+  individually obtained and released from the host system. A request
+  serviced through mmap is never reused by any other request (at least
+  not directly; the system may just so happen to remap successive
+  requests to the same locations).  Segregating space in this way has
+  the benefits that: Mmapped space can always be individually released
+  back to the system, which helps keep the system level memory demands
+  of a long-lived program low.  Also, mapped memory doesn't become
+  `locked' between other chunks, as can happen with normally allocated
+  chunks, which means that even trimming via malloc_trim would not
+  release them.  However, it has the disadvantage that the space
+  cannot be reclaimed, consolidated, and then used to service later
+  requests, as happens with normal chunks.  The advantages of mmap
+  nearly always outweigh disadvantages for "large" chunks, but the
+  value of "large" may vary across systems.  The default is an
+  empirically derived value that works well in most systems. You can
+  disable mmap by setting to MAX_SIZE_T.

+
+  independent_calloc is similar to calloc, but instead of returning a
+  single cleared space, it returns an array of pointers to n_elements
+  independent elements that can hold contents of size elem_size, each
+  of which starts out cleared, and can be independently freed,
+  realloc'ed etc. The elements are guaranteed to be adjacently
+  allocated (this is not guaranteed to occur with multiple callocs or
+  mallocs), which may also improve cache locality in some
+  applications.
+
+  The "chunks" argument is optional (i.e., may be null, which is
+  probably the most typical usage). If it is null, the returned array
+  is itself dynamically allocated and should also be freed when it is
+  no longer needed. Otherwise, the chunks array must be of at least
+  n_elements in length. It is filled in with the pointers to the
+  chunks.
+
+  In either case, independent_calloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and "chunks"
+  is null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use regular calloc and assign pointers into this
+  space to represent elements.  (In this case though, you cannot
+  independently free elements.)
+
+  independent_calloc simplifies and speeds up implementations of many
+  kinds of pools.  It may also be useful when constructing large data
+  structures that initially have a fixed number of fixed-sized nodes,
+  but the number is not known at compile time, and some of the nodes
+  may later need to be freed. For example:
+
+  struct Node { int item; struct Node* next; };
+
+  struct Node* build_list() {
+    struct Node** pool;
+    int n = read_number_of_nodes_needed();

+    pool = (struct Node**)(independent_calloc(n, sizeof(struct Node), 0);

+    // organize into a linked list...
+    struct Node* first = pool[0];
+    for (i = 0; i < n-1; ++i)
+      pool[i]->next = pool[i+1];
+    free(pool);     // Can now free the array (or not, if it is needed later)

+  independent_comalloc(size_t n_elements, size_t sizes[], void* chunks[]);
+
+  independent_comalloc allocates, all at once, a set of n_elements
+  chunks with sizes indicated in the "sizes" array.    It returns
+  an array of pointers to these elements, each of which can be
+  independently freed, realloc'ed etc. The elements are guaranteed to
+  be adjacently allocated (this is not guaranteed to occur with
+  multiple callocs or mallocs), which may also improve cache locality
+  in some applications.
+
+  The "chunks" argument is optional (i.e., may be null). If it is null
+  the returned array is itself dynamically allocated and should also
+  be freed when it is no longer needed. Otherwise, the chunks array
+  must be of at least n_elements in length. It is filled in with the
+  pointers to the chunks.
+
+  In either case, independent_comalloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and chunks is
+  null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use a single regular malloc, and assign pointers at
+  particular offsets in the aggregate space. (In this case though, you
+  cannot independently free elements.)
+
+  independent_comallac differs from independent_calloc in that each
+  element may have a different size, and also that it does not
+  automatically clear elements.
+
+  independent_comalloc can be used to speed up allocation in cases
+  where several structs or objects must always be allocated at the
+  same time.  For example:
+
+  struct Head { ... }
+  struct Foot { ... }
+
+  void send_message(char* msg) {

+    size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) };

+    char*        body = (char*)(chunks[1]);
+    struct Foot* foot = (struct Foot*)(chunks[2]);
+    // ...
+  }
+
+  In general though, independent_comalloc is worth using only for
+  larger values of n_elements. For small values, you probably won't
+  detect enough difference from series of malloc calls to bother.
+

+/*
+  (The following includes lightly edited explanations by Colin Plumb.)
+
+  The malloc_chunk declaration below is misleading (but accurate and
+  necessary).  It declares a "view" into memory allowing access to
+  necessary fields at known offsets from a given base.
+
+  Chunks of memory are maintained using a `boundary tag' method as
+  originally described by Knuth.  (See the paper by Paul Wilson
+  ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
+  techniques.)  Sizes of free chunks are stored both in the front of
+  each chunk and at the end.  This makes consolidating fragmented
+  chunks into bigger chunks fast.  The head fields also hold bits
+  representing whether chunks are free or in use.
+
+  Here are some pictures to make it clearer.  They are "exploded" to
+  show that the state of a chunk can be thought of as extending from
+  the high 31 bits of the head field of its header through the
+  prev_foot and PINUSE_BIT bit of the following chunk header.
+
+  A chunk that's in use looks like:
+
+   chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+           | Size of previous chunk (if P = 1)                             |

+  Note that since we always merge adjacent free chunks, the chunks
+  adjacent to a free chunk must be in use.
+
+  Given a pointer to a chunk (which can be derived trivially from the
+  payload pointer) we can, in O(1) time, find out whether the adjacent
+  chunks are free, and if so, unlink them from the lists that they
+  are on and merge them with the current chunk.
+
+  Chunks always begin on even word boundaries, so the mem portion
+  (which is returned to the user) is also on an even word boundary, and
+  thus at least double-word aligned.
+
+  The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
+  chunk size (which is always a multiple of two words), is an in-use
+  bit for the *previous* chunk.  If that bit is *clear*, then the
+  word before the current chunk size contains the previous chunk
+  size, and can be used to find the front of the previous chunk.
+  The very first chunk allocated always has this bit set, preventing
+  access to non-existent (or non-owned) memory. If pinuse is set for
+  any given chunk, then you CANNOT determine the size of the
+  previous chunk, and might even get a memory addressing fault when
+  trying to do so.
+
+  The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
+  the chunk size redundantly records whether the current chunk is
+  inuse. This redundancy enables usage checks within free and realloc,
+  and reduces indirection when freeing and consolidating chunks.
+
+  Each freshly allocated chunk must have both cinuse and pinuse set.
+  That is, each allocated chunk borders either a previously allocated
+  and still in-use chunk, or the base of its memory arena. This is
+  ensured by making all allocations from the the `lowest' part of any
+  found chunk.  Further, no free chunk physically borders another one,
+  so each free chunk is known to be preceded and followed by either
+  inuse chunks or the ends of memory.
+
+  Note that the `foot' of the current chunk is actually represented
+  as the prev_foot of the NEXT chunk. This makes it easier to
+  deal with alignments etc but can be very confusing when trying
+  to extend or adapt this code.
+
+  The exceptions to all this are
+
+     1. The special chunk `top' is the top-most available chunk (i.e.,
+        the one bordering the end of available memory). It is treated
+        specially.  Top is never included in any bin, is used only if
+        no other chunk is available, and is released back to the
+        system if it is very large (see M_TRIM_THRESHOLD).  In effect,
+        the top chunk is treated as larger (and thus less well
+        fitting) than any other available chunk.  The top chunk
+        doesn't update its trailing size field since there is no next
+        contiguous chunk that would have to index off it. However,
+        space is still allocated for it (TOP_FOOT_SIZE) to enable
+        separation or merging when space is extended.

+
+  Each tree holding treenodes is a tree of unique chunk sizes.  Chunks
+  of the same size are arranged in a circularly-linked list, with only
+  the oldest chunk (the next to be used, in our FIFO ordering)
+  actually in the tree.  (Tree members are distinguished by a non-null
+  parent pointer.)  If a chunk with the same size an an existing node
+  is inserted, it is linked off the existing node using pointers that
+  work in the same way as fd/bk pointers of small chunks.
+
+  Each tree contains a power of 2 sized range of chunk sizes (the
+  smallest is 0x100 <= x < 0x180), which is is divided in half at each
+  tree level, with the chunks in the smaller half of the range (0x100
+  <= x < 0x140 for the top nose) in the left subtree and the larger
+  half (0x140 <= x < 0x180) in the right subtree.  This is, of course,
+  done by inspecting individual bits.
+
+  Using these rules, each node's left subtree contains all smaller
+  sizes than its right subtree.  However, the node at the root of each
+  subtree has no particular ordering relationship to either.  (The
+  dividing line between the subtree sizes is based on trie relation.)
+  If we remove the last chunk of a given size from the interior of the
+  tree, we need to replace it with a leaf node.  The tree ordering
+  rules permit a node to be replaced by any leaf below it.
+
+  The smallest chunk in a tree (a common operation in a best-fit
+  allocator) can be found by walking a path to the leftmost leaf in
+  the tree.  Unlike a usual binary tree, where we follow left child
+  pointers until we reach a null, here we follow the right child
+  pointer any time the left one is null, until we reach a leaf with
+  both child pointers null. The smallest chunk in the tree will be
+  somewhere along that path.
+
+  The worst case number of steps to add, find, or remove a node is
+  bounded by the number of bits differentiating chunks within
+  bins. Under current bin calculations, this ranges from 6 up to 21
+  (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case
+  is of course much better.

+/* ----------------------------- Segments -------------------------------- */
+
+/*
+  Each malloc space may include non-contiguous segments, held in a
+  list headed by an embedded malloc_segment record representing the
+  top-most space. Segments also include flags holding properties of
+  the space. Large chunks that are directly allocated by mmap are not
+  included in this list. They are instead independently created and
+  destroyed without otherwise keeping track of them.
+
+  Segment management mainly comes into play for spaces allocated by
+  MMAP.  Any call to MMAP might or might not return memory that is
+  adjacent to an existing segment.  MORECORE normally contiguously
+  extends the current space, so this space is almost always adjacent,
+  which is simpler and faster to deal with. (This is why MORECORE is
+  used preferentially to MMAP when both are available -- see
+  sys_alloc.)  When allocating using MMAP, we don't use any of the
+  hinting mechanisms (inconsistently) supported in various
+  implementations of unix mmap, or distinguish reserving from
+  committing memory. Instead, we just ask for space, and exploit
+  contiguity when we get it.  It is probably possible to do
+  better than this on some systems, but no general scheme seems
+  to be significantly better.
+
+  Management entails a simpler variant of the consolidation scheme
+  used for chunks to reduce fragmentation -- new adjacent memory is
+  normally prepended or appended to an existing segment. However,
+  there are limitations compared to chunk consolidation that mostly
+  reflect the fact that segment processing is relatively infrequent
+  (occurring only when getting memory from system) and that we
+  don't expect to have huge numbers of segments:
+
+  * Segments are not indexed, so traversal requires linear scans.  (It
+    would be possible to index these, but is not worth the extra
+    overhead and complexity for most programs on most platforms.)
+  * New segments are only appended to old ones when holding top-most
+    memory; if they cannot be prepended to others, they are held in
+    different segments.
+
+  Except for the top-most segment of an mstate, each segment record
+  is kept at the tail of its segment. Segments are added by pushing
+  segment records onto the list headed by &mstate.seg for the
+  containing mstate.
+
+  Segment flags control allocation/merge/deallocation policies:
+  * If EXTERN_BIT set, then we did not allocate this segment,
+    and so should not try to deallocate or merge with others.
+    (This currently holds only for the initial segment passed
+    into create_mspace_with_base.)
+  * If IS_MMAPPED_BIT set, the segment may be merged with
+    other surrounding mmapped segments and trimmed/de-allocated
+    using munmap.
+  * If neither bit is set, then the segment was obtained using
+    MORECORE so can be merged with surrounding MORECORE'd segments
+    and deallocated/trimmed using MORECORE with negative arguments.

+   A malloc_state holds all of the bookkeeping for a space.
+   The main fields are:
+
+  Top
+    The topmost chunk of the currently active segment. Its size is
+    cached in topsize.  The actual size of topmost space is
+    topsize+TOP_FOOT_SIZE, which includes space reserved for adding
+    fenceposts and segment records if necessary when getting more
+    space from the system.  The size at which to autotrim top is
+    cached from mparams in trim_check, except that it is disabled if
+    an autotrim fails.
+
+  Designated victim (dv)
+    This is the preferred chunk for servicing small requests that
+    don't have exact fits.  It is normally the chunk split off most
+    recently to service another small request.  Its size is cached in
+    dvsize. The link fields of this chunk are not maintained since it
+    is not kept in a bin.
+
+  SmallBins
+    An array of bin headers for free chunks.  These bins hold chunks
+    with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
+    chunks of all the same size, spaced 8 bytes apart.  To simplify
+    use in double-linked lists, each bin header acts as a malloc_chunk
+    pointing to the real first node, if it exists (else pointing to
+    itself).  This avoids special-casing for headers.  But to avoid
+    waste, we allocate only the fd/bk pointers of bins, and then use
+    repositioning tricks to treat these as the fields of a chunk.
+
+  TreeBins
+    Treebins are pointers to the roots of trees holding a range of
+    sizes. There are 2 equally spaced treebins for each power of two
+    from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
+    larger.
+
+  Bin maps
+    There is one bit map for small bins ("smallmap") and one for
+    treebins ("treemap).  Each bin sets its bit when non-empty, and
+    clears the bit when empty.  Bit operations are then used to avoid
+    bin-by-bin searching -- nearly all "search" is done without ever
+    looking at bins that won't be selected.  The bit maps
+    conservatively use 32 bits per map word, even if on 64bit system.
+    For a good description of some of the bit-based techniques used
+    here, see Henry S. Warren Jr's book "Hacker's Delight" (and
+    supplement at http://hackersdelight.org/). Many of these are
+    intended to reduce the branchiness of paths through malloc etc, as
+    well as to reduce the number of memory locations read or written.
+
+  Segments
+    A list of segments headed by an embedded malloc_segment record
+    representing the initial space.
+
+  Address check support
+    The least_addr field is the least address ever obtained from
+    MORECORE or MMAP. Attempted frees and reallocs of any address less
+    than this are trapped (unless INSECURE is defined).
+
+  Magic tag
+    A cross-check field that should always hold same value as mparams.magic.
+
+  Flags
+    Bits recording whether to use MMAP, locks, or contiguous MORECORE
+
+  Statistics
+    Each space keeps track of current and maximum system memory
+    obtained via MORECORE or MMAP.
+
+  Locking
+    If USE_LOCKS is defined, the "mutex" lock is acquired and released
+    around every public call using this mspace.

+  For security, the main invariant is that malloc/free/etc never
+  writes to a static address other than malloc_state, unless static
+  malloc_state itself has been corrupted, which cannot occur via
+  malloc (because of these checks). In essence this means that we
+  believe all pointers, sizes, maps etc held in malloc_state, but
+  check all of those linked or offsetted from other embedded data
+  structures.  These checks are interspersed with main code in a way
+  that tends to minimize their run-time cost.
+
+  When FOOTERS is defined, in addition to range checking, we also
+  verify footer fields of inuse chunks, which can be used guarantee
+  that the mstate controlling malloc/free is intact.  This is a
+  streamlined version of the approach described by William Robertson
+  et al in "Run-time Detection of Heap-based Overflows" LISA'03
+  http://www.usenix.org/events/lisa03/tech/robertson.html The footer
+  of an inuse chunk holds the xor of its mstate and a random seed,
+  that is checked upon calls to free() and realloc().  This is
+  (probablistically) unguessable from outside the program, but can be
+  computed by any code successfully malloc'ing any chunk, so does not
+  itself provide protection against code that has already broken
+  security through some other means.  Unlike Robertson et al, we
+  always dynamically check addresses of all offset chunks (previous,
+  next, etc). This turns out to be cheaper than relying on hashes.

+/* -------------------- Alternative MORECORE functions ------------------- */
+
+/*
+  Guidelines for creating a custom version of MORECORE:
+
+  * For best performance, MORECORE should allocate in multiples of pagesize.
+  * MORECORE may allocate more memory than requested. (Or even less,
+      but this will usually result in a malloc failure.)
+  * MORECORE must not allocate memory when given argument zero, but
+      instead return one past the end address of memory from previous
+      nonzero call.
+  * For best performance, consecutive calls to MORECORE with positive
+      arguments should return increasing addresses, indicating that
+      space has been contiguously extended.
+  * Even though consecutive calls to MORECORE need not return contiguous
+      addresses, it must be OK for malloc'ed chunks to span multiple
+      regions in those cases where they do happen to be contiguous.
+  * MORECORE need not handle negative arguments -- it may instead
+      just return MFAIL when given negative arguments.
+      Negative arguments are always multiples of pagesize. MORECORE
+      must not misinterpret negative args as large positive unsigned
+      args. You can suppress all such calls from even occurring by defining
+      MORECORE_CANNOT_TRIM,
+
+  As an example alternative MORECORE, here is a custom allocator
+  kindly contributed for pre-OSX macOS.  It uses virtually but not
+  necessarily physically contiguous non-paged memory (locked in,
+  present and won't get swapped out).  You can use it by uncommenting
+  this section, adding some #includes, and setting up the appropriate
+  defines above:
+
+      #define MORECORE osMoreCore
+
+  There is also a shutdown routine that should somehow be called for
+  cleanup upon program exit.
+
+  #define MAX_POOL_ENTRIES 100
+  #define MINIMUM_MORECORE_SIZE  (64 * 1024U)
+  static int next_os_pool;
+  void *our_os_pools[MAX_POOL_ENTRIES];
+
+  void *osMoreCore(int size)
+  {
+    void *ptr = 0;
+    static void *sbrk_top = 0;
+
+    if (size > 0)
+    {
+      if (size < MINIMUM_MORECORE_SIZE)
+         size = MINIMUM_MORECORE_SIZE;
+      if (CurrentExecutionLevel() == kTaskLevel)
+         ptr = PoolAllocateResident(size + RM_PAGE_SIZE, 0);
+      if (ptr == 0)
+      {
+        return (void *) MFAIL;
+      }
+      // save ptrs so they can be freed during cleanup
+      our_os_pools[next_os_pool] = ptr;
+      next_os_pool++;
+      ptr = (void *) ((((size_t) ptr) + RM_PAGE_MASK) & ~RM_PAGE_MASK);
+      sbrk_top = (char *) ptr + size;
+      return ptr;

+    V2.6.2 Tue Dec  5 06:52:55 1995  Doug Lea  (dl at gee)
+      * Integrated most documentation with the code.
+      * Add support for mmap, with help from
+        Wolfram Gloger (Gloger@lrz.uni-muenchen.de).

+      * Add `pad' argument to malloc_trim and top_pad mallopt parameter.
+      * More precautions for cases where other routines call sbrk,
+        courtesy of Wolfram Gloger (Gloger@lrz.uni-muenchen.de).
+      * Added macros etc., allowing use in linux libc from
+        H.J. Lu (hjl@gnu.ai.mit.edu)
+      * Inverted this history list
+
+    V2.6.1 Sat Dec  2 14:10:57 1995  Doug Lea  (dl at gee)
+      * Re-tuned and fixed to behave more nicely with V2.6.0 changes.
+      * Removed all preallocation code since under current scheme
+        the work required to undo bad preallocations exceeds
+        the work saved in good cases for most test programs.
+      * No longer use return list or unconsolidated bins since
+        no scheme using them consistently outperforms those that don't
+        given above changes.
+      * Use best fit for very large chunks to prevent some worst-cases.
+      * Added some support for debugging
+
+    V2.6.0 Sat Nov  4 07:05:23 1995  Doug Lea  (dl at gee)

+
+    V2.5.2 Tue Apr  5 16:20:40 1994  Doug Lea  (dl at g)
+      * realloc: try to expand in both directions
+      * malloc: swap order of clean-bin strategy;
+      * realloc: only conditionally expand backwards
+      * Try not to scavenge used bins
+      * Use bin counts as a guide to preallocation
+      * Occasionally bin return list chunks in first scan
+      * Add a few optimizations from colin@nyx10.cs.du.edu
+
+    V2.5.1 Sat Aug 14 15:40:43 1993  Doug Lea  (dl at g)
+      * faster bin computation & slightly different binning
+      * merged all consolidations to one part of malloc proper
+         (eliminating old malloc_find_space & malloc_clean_bin)
+      * Scan 2 returns chunks (not just 1)
+      * Propagate failure in realloc if malloc returns 0
+      * Add stuff to allow compilation on non-ANSI compilers
+          from kpv@research.att.com

+      * removed potential for odd address access in prev_chunk
+      * removed dependency on getpagesize.h
+      * misc cosmetics and a bit more internal documentation
+      * anticosmetics: mangled names in macros to evade debugger strangeness
+      * tested on sparc, hp-700, dec-mips, rs6000
+          with gcc & native cc (hp, dec only) allowing
+          Detlefs & Zorn comparison study (in SIGPLAN Notices.)
+
+    Trial version Fri Aug 28 13:14:29 1992  Doug Lea  (dl at g.oswego.edu)
+      * Based loosely on libg++-1.2X malloc. (It retains some of the overall
+         structure of old version,  but most details differ.)

+   SP-52                arg word 4
+	[ Fixed args ]
+   SP-48                arg word 3

+	[ Frame marker ]
+   ...
+   SP-20                RP
+   SP-4                 previous SP
+
+   The first four argument words on the stack are reserved for use by
+   the callee.  Instead, the general and floating registers replace
+   the first four argument slots.  Non FP arguments are passed solely
+   in the general registers.  FP arguments are passed in both general
+   and floating registers when using libffi.
+
+   Non-FP 32-bit args are passed in gr26, gr25, gr24 and gr23.
+   Non-FP 64-bit args are passed in register pairs, starting
+   on an odd numbered register (i.e. r25+r26 and r23+r24).
+   FP 32-bit arguments are passed in fr4L, fr5L, fr6L and fr7L.
+   FP 64-bit arguments are passed in fr5 and fr7.
+
+   The registers are allocated in the same manner as stack slots.
+   This allows the callee to save its arguments on the stack if
+   necessary:
+
+   arg word 3 -> gr23 or fr7L
+   arg word 2 -> gr24 or fr6L or fr7R
+   arg word 1 -> gr25 or fr5L
+   arg word 0 -> gr26 or fr4L or fr5R
+
+   Note that fr4R and fr6R are never used for arguments (i.e.,
+   doubles are not passed in fr4 or fr6).
+
+   The rest of the arguments are passed on the stack starting at SP-52,
+   but 64-bit arguments need to be aligned to an 8-byte boundary
+
+   This means we can have holes either in the register allocation,
+   or in the stack.  */

+%
+% As a special exception, when this file is read by TeX when processing
+% a Texinfo source document, you may use the result without
+% restriction.  (This has been our intent since Texinfo was invented.)
+%
+% Please try the latest version of texinfo.tex before submitting bug
+% reports; you can get the latest version from:
+%   http://www.gnu.org/software/texinfo/ (the Texinfo home page), or
+%   ftp://tug.org/tex/texinfo.tex
+%     (and all CTAN mirrors, see http://www.ctan.org).
+% The texinfo.tex in any given distribution could well be out
+% of date, so if that's what you're using, please check.
+%
+% Send bug reports to bug-texinfo@gnu.org.  Please include including a
+% complete document in each bug report with which we can reproduce the
+% problem.  Patches are, of course, greatly appreciated.
+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For a simple
+% manual foo.texi, however, you can get away with this:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent.  You can get the existing language-specific files from the
+% full Texinfo distribution.
+%
+% The GNU Texinfo home page is http://www.gnu.org/software/texinfo.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.
