Subject: fix minsize-related issues with Label

 - fixed end of string adding to Label minsize
 - exposed set_clip_text() and is_clipping_text() to the script side
 - text would now never stick outside its boundaries
 - label min-height is now restricted by max_lines_visible

Subject: Ability to keep collisionshapes and collisionpolygons when running
 the game. Works for 2D and 3D These are still just helpers in case you want
 to animate them or access them directly. Modifying the real shapes is still
 done via CollisionObject and CollisionObject2D APIs But an API was added so
 you can query which shapes from CollisionObject correspond to which
 CollisionShape.

Have Fun!

 	CollisionObject2D is the base class for 2D physics collisionables. They can hold any number of 2D collision shapes. Usually, they are edited by placing CollisionBody2D and CollisionPolygon2D nodes as children. Such nodes are for reference ant not present outside the editor, so code should use the regular shape API.

+	Main loop is the abstract main loop base class. All other main loop classes are derived from it. Upon application start, a [MainLoop] has to be provided to OS, else the application will exit. This happens automatically (and a [SceneMainLoop] is created), unless a main [Script] is supplied, which may or not create and return a [MainLoop].

 	To optimize drawing and culling (sort of like [GridMap]), you can specify a quadrant size, so chunks of the map will be batched together at drawing time.

-/* ChangeLog for this library:
- *
- * NDK r8d: Add android_setCpu().
- *
- * NDK r8c: Add new ARM CPU features: VFPv2, VFP_D32, VFP_FP16,
- *          VFP_FMA, NEON_FMA, IDIV_ARM, IDIV_THUMB2 and iWMMXt.
- *
- *          Rewrite the code to parse /proc/self/auxv instead of
- *          the "Features" field in /proc/cpuinfo.
- *
- *          Dynamically allocate the buffer that hold the content
- *          of /proc/cpuinfo to deal with newer hardware.
- *
- * NDK r7c: Fix CPU count computation. The old method only reported the
- *           number of _active_ CPUs when the library was initialized,
- *           which could be less than the real total.
- *
- * NDK r5: Handle buggy kernels which report a CPU Architecture number of 7
- *         for an ARMv6 CPU (see below).
- *
- *         Handle kernels that only report 'neon', and not 'vfpv3'
- *         (VFPv3 is mandated by the ARM architecture is Neon is implemented)
- *
- *         Handle kernels that only report 'vfpv3d16', and not 'vfpv3'
- *
- *         Fix x86 compilation. Report ANDROID_CPU_FAMILY_X86 in
- *         android_getCpuFamily().
- *
- * NDK r4: Initial release

- * Technical note: Making sense of ARM's FPU architecture versions.
- *
- * FPA was ARM's first attempt at an FPU architecture. There is no Android
- * device that actually uses it since this technology was already obsolete
- * when the project started. If you see references to FPA instructions
- * somewhere, you can be sure that this doesn't apply to Android at all.
- *
- * FPA was followed by "VFP", soon renamed "VFPv1" due to the emergence of
- * new versions / additions to it. ARM considers this obsolete right now,
- * and no known Android device implements it either.
- *
- * VFPv2 added a few instructions to VFPv1, and is an *optional* extension
- * supported by some ARMv5TE, ARMv6 and ARMv6T2 CPUs. Note that a device
- * supporting the 'armeabi' ABI doesn't necessarily support these.
- *
- * VFPv3-D16 adds a few instructions on top of VFPv2 and is typically used
- * on ARMv7-A CPUs which implement a FPU. Note that it is also mandated
- * by the Android 'armeabi-v7a' ABI. The -D16 suffix in its name means
- * that it provides 16 double-precision FPU registers (d0-d15) and 32
- * single-precision ones (s0-s31) which happen to be mapped to the same
- * register banks.
- *
- * VFPv3-D32 is the name of an extension to VFPv3-D16 that provides 16
- * additional double precision registers (d16-d31). Note that there are
- * still only 32 single precision registers.
- *
- * VFPv3xD is a *subset* of VFPv3-D16 that only provides single-precision
- * registers. It is only used on ARMv7-M (i.e. on micro-controllers) which
- * are not supported by Android. Note that it is not compatible with VFPv2.
- *
- * NOTE: The term 'VFPv3' usually designate either VFPv3-D16 or VFPv3-D32
- *       depending on context. For example GCC uses it for VFPv3-D32, but
- *       the Linux kernel code uses it for VFPv3-D16 (especially in
- *       /proc/cpuinfo). Always try to use the full designation when
- *       possible.
- *
- * NEON, a.k.a. "ARM Advanced SIMD" is an extension that provides
- * instructions to perform parallel computations on vectors of 8, 16,
- * 32, 64 and 128 bit quantities. NEON requires VFPv32-D32 since all
- * NEON registers are also mapped to the same register banks.
- *
- * VFPv4-D16, adds a few instructions on top of VFPv3-D16 in order to
- * perform fused multiply-accumulate on VFP registers, as well as
- * half-precision (16-bit) conversion operations.
- *
- * VFPv4-D32 is VFPv4-D16 with 32, instead of 16, FPU double precision
- * registers.
- *
- * VPFv4-NEON is VFPv4-D32 with NEON instructions. It also adds fused
- * multiply-accumulate instructions that work on the NEON registers.
- *
- * NOTE: Similarly, "VFPv4" might either reference VFPv4-D16 or VFPv4-D32
- *       depending on context.
- *
- * The following information was determined by scanning the binutils-2.22
- * sources:
- *
- * Basic VFP instruction subsets:
- *
- * #define FPU_VFP_EXT_V1xD 0x08000000     // Base VFP instruction set.
- * #define FPU_VFP_EXT_V1   0x04000000     // Double-precision insns.
- * #define FPU_VFP_EXT_V2   0x02000000     // ARM10E VFPr1.
- * #define FPU_VFP_EXT_V3xD 0x01000000     // VFPv3 single-precision.
- * #define FPU_VFP_EXT_V3   0x00800000     // VFPv3 double-precision.
- * #define FPU_NEON_EXT_V1  0x00400000     // Neon (SIMD) insns.
- * #define FPU_VFP_EXT_D32  0x00200000     // Registers D16-D31.
- * #define FPU_VFP_EXT_FP16 0x00100000     // Half-precision extensions.
- * #define FPU_NEON_EXT_FMA 0x00080000     // Neon fused multiply-add

-/* The list of feature flags for ARM CPUs that can be recognized by the
- * library. Value details are:
- *
- *   VFPv2:
- *     CPU supports the VFPv2 instruction set. Many, but not all, ARMv6 CPUs
- *     support these instructions. VFPv2 is a subset of VFPv3 so this will
- *     be set whenever VFPv3 is set too.
- *
- *   ARMv7:
- *     CPU supports the ARMv7-A basic instruction set.
- *     This feature is mandated by the 'armeabi-v7a' ABI.
- *
- *   VFPv3:
- *     CPU supports the VFPv3-D16 instruction set, providing hardware FPU
- *     support for single and double precision floating point registers.
- *     Note that only 16 FPU registers are available by default, unless
- *     the D32 bit is set too. This feature is also mandated by the
- *     'armeabi-v7a' ABI.
- *
- *   VFP_D32:
- *     CPU VFP optional extension that provides 32 FPU registers,
- *     instead of 16. Note that ARM mandates this feature is the 'NEON'
- *     feature is implemented by the CPU.
- *
- *   NEON:
- *     CPU FPU supports "ARM Advanced SIMD" instructions, also known as
- *     NEON. Note that this mandates the VFP_D32 feature as well, per the
- *     ARM Architecture specification.
- *
- *   VFP_FP16:
- *     Half-width floating precision VFP extension. If set, the CPU
- *     supports instructions to perform floating-point operations on
- *     16-bit registers. This is part of the VFPv4 specification, but
- *     not mandated by any Android ABI.
- *
- *   VFP_FMA:
- *     Fused multiply-accumulate VFP instructions extension. Also part of
- *     the VFPv4 specification, but not mandated by any Android ABI.
- *
- *   NEON_FMA:
- *     Fused multiply-accumulate NEON instructions extension. Optional
- *     extension from the VFPv4 specification, but not mandated by any
- *     Android ABI.
- *
- *   IDIV_ARM:
- *     Integer division available in ARM mode. Only available
- *     on recent CPUs (e.g. Cortex-A15).
- *
- *   IDIV_THUMB2:
- *     Integer division available in Thumb-2 mode. Only available
- *     on recent CPUs (e.g. Cortex-A15).
- *
- *   iWMMXt:
- *     Optional extension that adds MMX registers and operations to an
- *     ARM CPU. This is only available on a few XScale-based CPU designs
- *     sold by Marvell. Pretty rare in practice.
- *
- * If you want to tell the compiler to generate code that targets one of
- * the feature set above, you should probably use one of the following
- * flags (for more details, see technical note at the end of this file):
- *
- *   -mfpu=vfp
- *   -mfpu=vfpv2
- *     These are equivalent and tell GCC to use VFPv2 instructions for
- *     floating-point operations. Use this if you want your code to
- *     run on *some* ARMv6 devices, and any ARMv7-A device supported
- *     by Android.
- *
- *     Generated code requires VFPv2 feature.
- *
- *   -mfpu=vfpv3-d16
- *     Tell GCC to use VFPv3 instructions (using only 16 FPU registers).
- *     This should be generic code that runs on any CPU that supports the
- *     'armeabi-v7a' Android ABI. Note that no ARMv6 CPU supports this.
- *
- *     Generated code requires VFPv3 feature.
- *
- *   -mfpu=vfpv3
- *     Tell GCC to use VFPv3 instructions with 32 FPU registers.
- *     Generated code requires VFPv3|VFP_D32 features.
- *
- *   -mfpu=neon
- *     Tell GCC to use VFPv3 instructions with 32 FPU registers, and
- *     also support NEON intrinsics (see <arm_neon.h>).
- *     Generated code requires VFPv3|VFP_D32|NEON features.
- *
- *   -mfpu=vfpv4-d16
- *     Generated code requires VFPv3|VFP_FP16|VFP_FMA features.
- *
- *   -mfpu=vfpv4
- *     Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32 features.
- *
- *   -mfpu=neon-vfpv4
- *     Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32|NEON|NEON_FMA
- *     features.
- *
- *   -mcpu=cortex-a7
- *   -mcpu=cortex-a15
- *     Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32|
- *                             NEON|NEON_FMA|IDIV_ARM|IDIV_THUMB2
- *     This flag implies -mfpu=neon-vfpv4.
- *
- *   -mcpu=iwmmxt
- *     Allows the use of iWMMXt instrinsics with GCC.

-; This is a header file for the x264ASM assembly language, which uses
-; NASM/YASM syntax combined with a large number of macros to provide easy
-; abstraction between different calling conventions (x86_32, win64, linux64).
-; It also has various other useful features to simplify writing the kind of
-; DSP functions that are most often used in x264.
-
-; Unlike the rest of x264, this file is available under an ISC license, as it
-; has significant usefulness outside of x264 and we want it to be available

-; purposes to add a new feature, we strongly encourage contributing a patch
-; as this feature might be useful for others as well.  Send patches or ideas
-; to x264-devel@videolan.org .

-; Currently this works only for leaf functions which load all their arguments
-; into registers at the start, and make no other use of the stack. Luckily that
-; covers most of x264's asm.
-
-; PROLOGUE:
-; %1 = number of arguments. loads them from stack if needed.
-; %2 = number of registers used. pushes callee-saved regs if needed.
-; %3 = number of xmm registers used. pushes callee-saved xmm regs if needed.
-; %4 = list of names to define to registers
-; PROLOGUE can also be invoked by adding the same options to cglobal
-
-; e.g.
-; cglobal foo, 2,3,0, dst, src, tmp
-; declares a function (foo), taking two args (dst and src) and one local variable (tmp)
-
-; TODO Some functions can use some args directly from the stack. If they're the
-; last args then you can just not declare them, but if they're in the middle
-; we need more flexible macro.
-
-; RET:
-; Pops anything that was pushed by PROLOGUE, and returns.
-
-; REP_RET:
-; Same, but if it doesn't pop anything it becomes a 2-byte ret, for athlons
-; which are slow when a normal ret follows a branch.
-
-; registers:
-; rN and rNq are the native-size register holding function argument N
-; rNd, rNw, rNb are dword, word, and byte size
-; rNh is the high 8 bits of the word size
-; rNm is the original location of arg N (a register or on the stack), dword
-; rNmp is native size

-; I often want to use macros that permute their arguments. e.g. there's no
-; efficient way to implement butterfly or transpose or dct without swapping some
-; arguments.
-;
-; I would like to not have to manually keep track of the permutations:
-; If I insert a permutation in the middle of a function, it should automatically
-; change everything that follows. For more complex macros I may also have multiple
-; implementations, e.g. the SSE2 and SSSE3 versions may have different permutations.
-;
-; Hence these macros. Insert a PERMUTE or some SWAPs at the end of a macro that

From e055247b17dc9b9d7239b95da2207388d05fd770 Mon Sep 17 00:00:00 2001
From: Juan Linietsky
Date: Thu, 1 Oct 2015 16:25:36 -0300
Subject: -Added ability to use cubic interpolation on image resize (little
 more quality on non-po2 resizing) -Added ability for exporter to shrink
 images to non-integer values. Helps if you want to convert your game artwork
 from 1080->720 or similar

-#
-# 	- MSVC2010-Express compiles to 32bits only.
-#
-#####
-# Notes about Mingw-w64 and Mingw-w32 under Windows :
-#
-#	- both can be installed using the official installer :
-#		http://mingw-w64.sourceforge.net/download.php#mingw-builds
-#
-#	- if you want to compile both 32bits and 64bits, don't forget to
-#	run the installer twice to install them both.
-#
-#	- install them into a path that does not contain spaces
-#		( example : "C:/Mingw-w32", "C:/Mingw-w64" )
-#
-#	- if you want to compile faster using the "-j" option, don't forget
-#	to install the appropriate version of the Pywin32 python extension 
-#	available from : http://sourceforge.net/projects/pywin32/files/
-#
-#	- before running scons, you must add into the environment path 
-#	the path to the "/bin" directory of the Mingw version you want 
-#	to use :
-#
-#		set PATH=C:/Mingw-w32/bin;%PATH%
-#
-#	- then, scons should be able to detect gcc.
-#	- Mingw-w32 only compiles 32bits.
-#	- Mingw-w64 only compiles 64bits.
-#
-#	- it is possible to add them both at the same time into the PATH env, 
-#	if you also define the MINGW32_PREFIX and MINGW64_PREFIX environment 
-#	variables. 
-#	For instance, you could store that set of commands into a .bat script
-#	that you would run just before scons :
-#
-#			set PATH=C:\mingw-w32\bin;%PATH%
-#			set PATH=C:\mingw-w64\bin;%PATH%
-#			set MINGW32_PREFIX=C:\mingw-w32\bin\
-#			set MINGW64_PREFIX=C:\mingw-w64\bin\
-#
-#####
-# Notes about Mingw, Mingw-w64 and Mingw-w32 under Linux :
-#
-#	- default toolchain prefixes are :
-#		"i586-mingw32msvc-" for MinGW
-#		"i686-w64-mingw32-"	for Mingw-w32
-#		"x86_64-w64-mingw32-" for Mingw-w64
-#
-#	- if both MinGW and Mingw-w32 are installed on your system
-#	Mingw-w32 should take the priority over MinGW.
-#
-#	- it is possible to manually override prefixes by defining
-#	the MINGW32_PREFIX and MINGW64_PREFIX environment variables.
-#	
-#####
-# Notes about Mingw under Windows :
-#
-#	- this is the MinGW version from http://mingw.org/ 
-#	- install it into a path that does not contain spaces
-#		( example : "C:/MinGW" )
-#	- several DirectX headers might be missing. You can copy them into 
-#	the C:/MinGW/include" directory from this page :
-#	 https://code.google.com/p/mingw-lib/source/browse/trunk/working/avcodec_to_widget_5/directx_include/
-#	- before running scons, add the path to the "/bin" directory :
-#		set PATH=C:/MinGW/bin;%PATH%
-#	- scons should be able to detect gcc.
-#
-
-#####
-# TODO :
-#
-#	- finish to cleanup this script to remove all the remains of previous hacks and workarounds
-#	- make it work with the Windows7 SDK that is supposed to enable 64bits compilation for MSVC2010-Express
-#	- confirm it works well with other Visual Studio versions.
-#	- update the wiki about the pywin32 extension required for the "-j" option under Windows.
-#	- update the wiki to document MINGW32_PREFIX and MINGW64_PREFIX

+/*Although derived separately, the pulse vector coding scheme is equivalent to
+   a Pyramid Vector Quantizer \cite{Fis86}.
+  Some additional notes about an early version appear at
+   http://people.xiph.org/~tterribe/notes/cwrs.html, but the codebook ordering
+   and the definitions of some terms have evolved since that was written.
+
+  The conversion from a pulse vector to an integer index (encoding) and back
+   (decoding) is governed by two related functions, V(N,K) and U(N,K).
+
+  V(N,K) = the number of combinations, with replacement, of N items, taken K
+   at a time, when a sign bit is added to each item taken at least once (i.e.,
+   the number of N-dimensional unit pulse vectors with K pulses).
+  One way to compute this is via
+    V(N,K) = K>0 ? sum(k=1...K,2**k*choose(N,k)*choose(K-1,k-1)) : 1,
+   where choose() is the binomial function.
+  A table of values for N<10 and K<10 looks like:
+  V[10][10] = {
+    {1,  0,   0,    0,    0,     0,     0,      0,      0,       0},
+    {1,  2,   2,    2,    2,     2,     2,      2,      2,       2},
+    {1,  4,   8,   12,   16,    20,    24,     28,     32,      36},
+    {1,  6,  18,   38,   66,   102,   146,    198,    258,     326},
+    {1,  8,  32,   88,  192,   360,   608,    952,   1408,    1992},
+    {1, 10,  50,  170,  450,  1002,  1970,   3530,   5890,    9290},
+    {1, 12,  72,  292,  912,  2364,  5336,  10836,  20256,   35436},
+    {1, 14,  98,  462, 1666,  4942, 12642,  28814,  59906,  115598},
+    {1, 16, 128,  688, 2816,  9424, 27008,  68464, 157184,  332688},
+    {1, 18, 162,  978, 4482, 16722, 53154, 148626, 374274,  864146}
+  };
+
+  U(N,K) = the number of such combinations wherein N-1 objects are taken at
+   most K-1 at a time.
+  This is given by
+    U(N,K) = sum(k=0...K-1,V(N-1,k))
+           = K>0 ? (V(N-1,K-1) + V(N,K-1))/2 : 0.
+  The latter expression also makes clear that U(N,K) is half the number of such
+   combinations wherein the first object is taken at least once.
+  Although it may not be clear from either of these definitions, U(N,K) is the
+   natural function to work with when enumerating the pulse vector codebooks,
+   not V(N,K).
+  U(N,K) is not well-defined for N=0, but with the extension
+    U(0,K) = K>0 ? 0 : 1,
+   the function becomes symmetric: U(N,K) = U(K,N), with a similar table:
+  U[10][10] = {
+    {1, 0,  0,   0,    0,    0,     0,     0,      0,      0},
+    {0, 1,  1,   1,    1,    1,     1,     1,      1,      1},
+    {0, 1,  3,   5,    7,    9,    11,    13,     15,     17},
+    {0, 1,  5,  13,   25,   41,    61,    85,    113,    145},
+    {0, 1,  7,  25,   63,  129,   231,   377,    575,    833},
+    {0, 1,  9,  41,  129,  321,   681,  1289,   2241,   3649},
+    {0, 1, 11,  61,  231,  681,  1683,  3653,   7183,  13073},
+    {0, 1, 13,  85,  377, 1289,  3653,  8989,  19825,  40081},
+    {0, 1, 15, 113,  575, 2241,  7183, 19825,  48639, 108545},
+    {0, 1, 17, 145,  833, 3649, 13073, 40081, 108545, 265729}
+  };
+
+  With this extension, V(N,K) may be written in terms of U(N,K):
+    V(N,K) = U(N,K) + U(N,K+1)
+   for all N>=0, K>=0.
+  Thus U(N,K+1) represents the number of combinations where the first element
+   is positive or zero, and U(N,K) represents the number of combinations where
+   it is negative.
+  With a large enough table of U(N,K) values, we could write O(N) encoding
+   and O(min(N*log(K),N+K)) decoding routines, but such a table would be
+   prohibitively large for small embedded devices (K may be as large as 32767
+   for small N, and N may be as large as 200).
+
+  Both functions obey the same recurrence relation:
+    V(N,K) = V(N-1,K) + V(N,K-1) + V(N-1,K-1),
+    U(N,K) = U(N-1,K) + U(N,K-1) + U(N-1,K-1),
+   for all N>0, K>0, with different initial conditions at N=0 or K=0.
+  This allows us to construct a row of one of the tables above given the
+   previous row or the next row.
+  Thus we can derive O(NK) encoding and decoding routines with O(K) memory
+   using only addition and subtraction.
+
+  When encoding, we build up from the U(2,K) row and work our way forwards.
+  When decoding, we need to start at the U(N,K) row and work our way backwards,
+   which requires a means of computing U(N,K).
+  U(N,K) may be computed from two previous values with the same N:
+    U(N,K) = ((2*N-1)*U(N,K-1) - U(N,K-2))/(K-1) + U(N,K-2)
+   for all N>1, and since U(N,K) is symmetric, a similar relation holds for two
+   previous values with the same K:
+    U(N,K>1) = ((2*K-1)*U(N-1,K) - U(N-2,K))/(N-1) + U(N-2,K)
+   for all K>1.
+  This allows us to construct an arbitrary row of the U(N,K) table by starting
+   with the first two values, which are constants.
+  This saves roughly 2/3 the work in our O(NK) decoding routine, but costs O(K)
+   multiplications.
+  Similar relations can be derived for V(N,K), but are not used here.
+
+  For N>0 and K>0, U(N,K) and V(N,K) take on the form of an (N-1)-degree
+   polynomial for fixed N.
+  The first few are
+    U(1,K) = 1,
+    U(2,K) = 2*K-1,
+    U(3,K) = (2*K-2)*K+1,
+    U(4,K) = (((4*K-6)*K+8)*K-3)/3,
+    U(5,K) = ((((2*K-4)*K+10)*K-8)*K+3)/3,
+   and
+    V(1,K) = 2,
+    V(2,K) = 4*K,
+    V(3,K) = 4*K*K+2,
+    V(4,K) = 8*(K*K+2)*K/3,
+    V(5,K) = ((4*K*K+20)*K*K+6)/3,
+   for all K>0.
+  This allows us to derive O(N) encoding and O(N*log(K)) decoding routines for
+   small N (and indeed decoding is also O(N) for N<3).

+/*A range decoder.
+  This is an entropy decoder based upon \cite{Mar79}, which is itself a
+   rediscovery of the FIFO arithmetic code introduced by \cite{Pas76}.
+  It is very similar to arithmetic encoding, except that encoding is done with
+   digits in any base, instead of with bits, and so it is faster when using
+   larger bases (i.e.: a byte).
+  The author claims an average waste of $\frac{1}{2}\log_b(2b)$ bits, where $b$
+   is the base, longer than the theoretical optimum, but to my knowledge there
+   is no published justification for this claim.
+  This only seems true when using near-infinite precision arithmetic so that
+   the process is carried out with no rounding errors.
+
+  An excellent description of implementation details is available at
+   http://www.arturocampos.com/ac_range.html
+  A recent work \cite{MNW98} which proposes several changes to arithmetic
+   encoding for efficiency actually re-discovers many of the principles
+   behind range encoding, and presents a good theoretical analysis of them.
+
+  End of stream is handled by writing out the smallest number of bits that
+   ensures that the stream will be correctly decoded regardless of the value of
+   any subsequent bits.
+  ec_tell() can be used to determine how many bits were needed to decode
+   all the symbols thus far; other data can be packed in the remaining bits of
+   the input buffer.

+**      On Intel Pentium processors (especially PIII and probably P4), converting
+**      from float to int is very slow. To meet the C specs, the code produced by
+**      most C compilers targeting Pentium needs to change the FPU rounding mode
+**      before the float to int conversion is performed.
+**
+**      Changing the FPU rounding mode causes the FPU pipeline to be flushed. It
+**      is this flushing of the pipeline which is so slow.
+**
+**      Fortunately the ISO C99 specifications define the functions lrint, lrintf,
+**      llrint and llrintf which fix this problem as a side effect.
+**
+**      On Unix-like systems, the configure process should have detected the
+**      presence of these functions. If they weren't found we have to replace them
+**      here with a standard C cast.

+ *
+ * The Opus codec is designed for interactive speech and audio transmission over the Internet.
+ * It is designed by the IETF Codec Working Group and incorporates technology from
+ * Skype's SILK codec and Xiph.Org's CELT codec.
+ *
+ * The Opus codec is designed to handle a wide range of interactive audio applications,
+ * including Voice over IP, videoconferencing, in-game chat, and even remote live music
+ * performances. It can scale from low bit-rate narrowband speech to very high quality
+ * stereo music. Its main features are:
+
+ * @li Sampling rates from 8 to 48 kHz
+ * @li Bit-rates from 6 kb/s to 510 kb/s
+ * @li Support for both constant bit-rate (CBR) and variable bit-rate (VBR)
+ * @li Audio bandwidth from narrowband to full-band
+ * @li Support for speech and music
+ * @li Support for mono and stereo
+ * @li Support for multichannel (up to 255 channels)
+ * @li Frame sizes from 2.5 ms to 60 ms
+ * @li Good loss robustness and packet loss concealment (PLC)
+ * @li Floating point and fixed-point implementation
+ *
+ * Documentation sections:

+/** @defgroup opus_encoder Opus Encoder
+  * @{
+  *
+  * @brief This page describes the process and functions used to encode Opus.
+  *
+  * Since Opus is a stateful codec, the encoding process starts with creating an encoder
+  * state. This can be done with:
+  *
+  * @code
+  * int          error;
+  * OpusEncoder *enc;
+  * enc = opus_encoder_create(Fs, channels, application, &error);
+  * @endcode
+  *
+  * From this point, @c enc can be used for encoding an audio stream. An encoder state
+  * @b must @b not be used for more than one stream at the same time. Similarly, the encoder
+  * state @b must @b not be re-initialized for each frame.
+  *
+  * While opus_encoder_create() allocates memory for the state, it's also possible
+  * to initialize pre-allocated memory:
+  *
+  * @code
+  * int          size;
+  * int          error;
+  * OpusEncoder *enc;
+  * size = opus_encoder_get_size(channels);
+  * enc = malloc(size);
+  * error = opus_encoder_init(enc, Fs, channels, application);
+  * @endcode
+  *
+  * where opus_encoder_get_size() returns the required size for the encoder state. Note that
+  * future versions of this code may change the size, so no assuptions should be made about it.
+  *
+  * The encoder state is always continuous in memory and only a shallow copy is sufficient
+  * to copy it (e.g. memcpy())
+  *
+  * It is possible to change some of the encoder's settings using the opus_encoder_ctl()
+  * interface. All these settings already default to the recommended value, so they should
+  * only be changed when necessary. The most common settings one may want to change are:
+  *
+  * @code
+  * opus_encoder_ctl(enc, OPUS_SET_BITRATE(bitrate));
+  * opus_encoder_ctl(enc, OPUS_SET_COMPLEXITY(complexity));
+  * opus_encoder_ctl(enc, OPUS_SET_SIGNAL(signal_type));
+  * @endcode
+  *
+  * where
+  *
+  * @arg bitrate is in bits per second (b/s)
+  * @arg complexity is a value from 1 to 10, where 1 is the lowest complexity and 10 is the highest
+  * @arg signal_type is either OPUS_AUTO (default), OPUS_SIGNAL_VOICE, or OPUS_SIGNAL_MUSIC
+  *
+  * See @ref opus_encoderctls and @ref opus_genericctls for a complete list of parameters that can be set or queried. Most parameters can be set or changed at any time during a stream.
+  *
+  * To encode a frame, opus_encode() or opus_encode_float() must be called with exactly one frame (2.5, 5, 10, 20, 40 or 60 ms) of audio data:
+  * @code
+  * len = opus_encode(enc, audio_frame, frame_size, packet, max_packet);
+  * @endcode
+  *
+  * where
+  * <ul>
+  * <li>audio_frame is the audio data in opus_int16 (or float for opus_encode_float())</li>
+  * <li>frame_size is the duration of the frame in samples (per channel)</li>
+  * <li>packet is the byte array to which the compressed data is written</li>
+  * <li>max_packet is the maximum number of bytes that can be written in the packet (4000 bytes is recommended).
+  *     Do not use max_packet to control VBR target bitrate, instead use the #OPUS_SET_BITRATE CTL.</li>
+  * </ul>
+  *
+  * opus_encode() and opus_encode_float() return the number of bytes actually written to the packet.
+  * The return value <b>can be negative</b>, which indicates that an error has occurred. If the return value
+  * is 1 byte, then the packet does not need to be transmitted (DTX).
+  *
+  * Once the encoder state if no longer needed, it can be destroyed with
+  *
+  * @code
+  * opus_encoder_destroy(enc);
+  * @endcode
+  *
+  * If the encoder was created with opus_encoder_init() rather than opus_encoder_create(),
+  * then no action is required aside from potentially freeing the memory that was manually
+  * allocated for it (calling free(enc) for the example above)
+  *

+  * @{
+  *
+  * @brief This page describes the process and functions used to decode Opus.
+  *
+  * The decoding process also starts with creating a decoder
+  * state. This can be done with:
+  * @code
+  * int          error;
+  * OpusDecoder *dec;
+  * dec = opus_decoder_create(Fs, channels, &error);
+  * @endcode
+  * where
+  * @li Fs is the sampling rate and must be 8000, 12000, 16000, 24000, or 48000
+  * @li channels is the number of channels (1 or 2)
+  * @li error will hold the error code in case of failure (or #OPUS_OK on success)
+  * @li the return value is a newly created decoder state to be used for decoding
+  *
+  * While opus_decoder_create() allocates memory for the state, it's also possible
+  * to initialize pre-allocated memory:
+  * @code
+  * int          size;
+  * int          error;
+  * OpusDecoder *dec;
+  * size = opus_decoder_get_size(channels);
+  * dec = malloc(size);
+  * error = opus_decoder_init(dec, Fs, channels);
+  * @endcode
+  * where opus_decoder_get_size() returns the required size for the decoder state. Note that
+  * future versions of this code may change the size, so no assuptions should be made about it.
+  *
+  * The decoder state is always continuous in memory and only a shallow copy is sufficient
+  * to copy it (e.g. memcpy())
+  *
+  * To decode a frame, opus_decode() or opus_decode_float() must be called with a packet of compressed audio data:
+  * @code
+  * frame_size = opus_decode(dec, packet, len, decoded, max_size, 0);
+  * @endcode
+  * where
+  *
+  * @li packet is the byte array containing the compressed data
+  * @li len is the exact number of bytes contained in the packet
+  * @li decoded is the decoded audio data in opus_int16 (or float for opus_decode_float())
+  * @li max_size is the max duration of the frame in samples (per channel) that can fit into the decoded_frame array
+  *
+  * opus_decode() and opus_decode_float() return the number of samples (per channel) decoded from the packet.
+  * If that value is negative, then an error has occurred. This can occur if the packet is corrupted or if the audio
+  * buffer is too small to hold the decoded audio.
+  *
+  * Opus is a stateful codec with overlapping blocks and as a result Opus
+  * packets are not coded independently of each other. Packets must be
+  * passed into the decoder serially and in the correct order for a correct
+  * decode. Lost packets can be replaced with loss concealment by calling
+  * the decoder with a null pointer and zero length for the missing packet.
+  *
+  * A single codec state may only be accessed from a single thread at
+  * a time and any required locking must be performed by the caller. Separate
+  * streams must be decoded with separate decoder states and can be decoded
+  * in parallel unless the library was compiled with NONTHREADSAFE_PSEUDOSTACK
+  * defined.

+  * The repacketizer can be used to merge multiple Opus packets into a single
+  * packet or alternatively to split Opus packets that have previously been

+  * whereas merging valid packets only succeeds if all frames have the same
+  * mode, bandwidth, and frame size, and when the total duration of the merged
+  * packet is no more than 120 ms.
+  * The repacketizer currently only operates on elementary Opus
+  * streams. It will not manipualte multistream packets successfully, except in
+  * the degenerate case where they consist of data from a single stream.
+  *
+  * The repacketizing process starts with creating a repacketizer state, either
+  * by calling opus_repacketizer_create() or by allocating the memory yourself,
+  * e.g.,
+  * @code

+  * if (rp != NULL)
+  *     opus_repacketizer_init(rp);

+  * Then the application should submit packets with opus_repacketizer_cat(),

+  * opus_repacketizer_out_range(), and then reset the state for the next set of
+  * input packets via opus_repacketizer_init().

+  * for which a frame size different from 2.5, 5, 10, or 20 ms is needed
+  * (for either complexity or latency reasons) and where interoperability
+  * is less important.
+  *
+  * In addition to the interoperability limitations the use of Opus custom
+  * disables a substantial chunk of the codec and generally lowers the
+  * quality available at a given bitrate. Normally when an application needs
+  * a different frame size from the codec it should buffer to match the
+  * sizes but this adds a small amount of delay which may be important
+  * in some very low latency applications. Some transports (especially
+  * constant rate RF transports) may also work best with frames of
+  * particular durations.
+  *
+  * Libopus only supports custom modes if they are enabled at compile time.
+  *
+  * The Opus Custom API is similar to the regular API but the
+  * @ref opus_encoder_create and @ref opus_decoder_create calls take
+  * an additional mode parameter which is a structure produced by
+  * a call to @ref opus_custom_mode_create. Both the encoder and decoder
+  * must create a mode using the same sample rate (fs) and frame size
+  * (frame size) so these parameters must either be signaled out of band
+  * or fixed in a particular implementation.
+  *
+  * Similar to regular Opus the custom modes support on the fly frame size
+  * switching, but the sizes available depend on the particular frame size in
+  * use. For some initial frame sizes on a single on the fly size is available.

+/** @defgroup opus_multistream Opus Multistream API
+  * @{
+  *
+  * The multistream API allows individual Opus streams to be combined into a
+  * single packet, enabling support for up to 255 channels. Unlike an
+  * elementary Opus stream, the encoder and decoder must negotiate the channel
+  * configuration before the decoder can successfully interpret the data in the
+  * packets produced by the encoder. Some basic information, such as packet
+  * duration, can be computed without any special negotiation.
+  *
+  * The format for multistream Opus packets is defined in the
+  * <a href="http://tools.ietf.org/html/draft-terriberry-oggopus">Ogg
+  * encapsulation specification</a> and is based on the self-delimited Opus
+  * framing described in Appendix B of <a href="http://tools.ietf.org/html/rfc6716">RFC 6716</a>.
+  * Normal Opus packets are just a degenerate case of multistream Opus packets,
+  * and can be encoded or decoded with the multistream API by setting
+  * <code>streams</code> to <code>1</code> when initializing the encoder or
+  * decoder.
+  *
+  * Multistream Opus streams can contain up to 255 elementary Opus streams.
+  * These may be either "uncoupled" or "coupled", indicating that the decoder
+  * is configured to decode them to either 1 or 2 channels, respectively.
+  * The streams are ordered so that all coupled streams appear at the
+  * beginning.
+  *
+  * A <code>mapping</code> table defines which decoded channel <code>i</code>
+  * should be used for each input/output (I/O) channel <code>j</code>. This table is
+  * typically provided as an unsigned char array.
+  * Let <code>i = mapping[j]</code> be the index for I/O channel <code>j</code>.
+  * If <code>i < 2*coupled_streams</code>, then I/O channel <code>j</code> is
+  * encoded as the left channel of stream <code>(i/2)</code> if <code>i</code>
+  * is even, or  as the right channel of stream <code>(i/2)</code> if
+  * <code>i</code> is odd. Otherwise, I/O channel <code>j</code> is encoded as
+  * mono in stream <code>(i - coupled_streams)</code>, unless it has the special
+  * value 255, in which case it is omitted from the encoding entirely (the
+  * decoder will reproduce it as silence). Each value <code>i</code> must either
+  * be the special value 255 or be less than <code>streams + coupled_streams</code>.
+  *
+  * The output channels specified by the encoder
+  * should use the
+  * <a href="http://www.xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-800004.3.9">Vorbis
+  * channel ordering</a>. A decoder may wish to apply an additional permutation
+  * to the mapping the encoder used to achieve a different output channel
+  * order (e.g. for outputing in WAV order).
+  *
+  * Each multistream packet contains an Opus packet for each stream, and all of
+  * the Opus packets in a single multistream packet must have the same
+  * duration. Therefore the duration of a multistream packet can be extracted
+  * from the TOC sequence of the first stream, which is located at the
+  * beginning of the packet, just like an elementary Opus stream:
+  *
+  * @code
+  * int nb_samples;
+  * int nb_frames;
+  * nb_frames = opus_packet_get_nb_frames(data, len);
+  * if (nb_frames < 1)
+  *   return nb_frames;
+  * nb_samples = opus_packet_get_samples_per_frame(data, 48000) * nb_frames;
+  * @endcode
+  *
+  * The general encoding and decoding process proceeds exactly the same as in
+  * the normal @ref opus_encoder and @ref opus_decoder APIs.
+  * See their documentation for an overview of how to use the corresponding
+  * multistream functions.

+   position.
+  We are not guaranteed to have an unsigned 64-bit type, so we construct the
+   following routines that
+   a) Properly order negative numbers as larger than positive numbers, and
+   b) Check for underflow or overflow past the special -1 value.
+  This lets us operate on the full, valid range of granule positions in a
+   consistent and safe manner.
+  This full range is organized into distinct regions:
+   [ -1 (invalid) ][ 0 ... OP_INT64_MAX ][ OP_INT64_MIN ... -2 ][-1 (invalid) ]
+
+  No one should actually use granule positions so large that they're negative,
+   even if they are technically valid, as very little software handles them
+   correctly (including most of Xiph.Org's).
+  This library also refuses to support durations so large they won't fit in a
+   signed 64-bit integer (to avoid exposing this mess to the application, and
+   to simplify a good deal of internal arithmetic), so the only way to use them
+   successfully is if pcm_start is very large.
+  This means there isn't anything you can do with negative granule positions
+   that you couldn't have done with purely non-negative ones.
+  The main purpose of these routines is to allow us to think very explicitly
+   about the possible failure cases of all granule position manipulations.*/

+  The 48 kHz version of this filter is just a warped version of the 44.1 kHz

+   suppression.
+  This process can increase the peak level of the signal (in theory by the peak
+   error of 1.5 +20 dB, though that is unobservably rare).
+  To avoid clipping, the signal is attenuated by a couple thousandths of a dB.
+  Initially, the approach taken here was to only attenuate by the 99.9th
+   percentile, making clipping rare but not impossible (like SoX), but the
+   limited gain of the filter means that the worst case was only two
+   thousandths of a dB more, so this just uses the worst case.
+  The attenuation is probably also helpful to prevent clipping in the DAC

+   \section Introduction
+
+   This is the documentation for the <tt>libopusfile</tt> C API.
+
+   The <tt>libopusfile</tt> package provides a convenient high-level API for
+    decoding and basic manipulation of all Ogg Opus audio streams.
+   <tt>libopusfile</tt> is implemented as a layer on top of Xiph.Org's
+    reference
+    <tt><a href="https://www.xiph.org/ogg/doc/libogg/reference.html">libogg</a></tt>
+    and
+    <tt><a href="https://mf4.xiph.org/jenkins/view/opus/job/opus/ws/doc/html/index.html">libopus</a></tt>
+    libraries.
+
+   <tt>libopusfile</tt> provides several sets of built-in routines for
+    file/stream access, and may also use custom stream I/O routines provided by
+    the embedded environment.
+   There are built-in I/O routines provided for ANSI-compliant
+    <code>stdio</code> (<code>FILE *</code>), memory buffers, and URLs
+    (including <file:> URLs, plus optionally <http:> and <https:> URLs).
+
+   \section Organization
+
+   The main API is divided into several sections:
+   - \ref stream_open_close
+   - \ref stream_info
+   - \ref stream_decoding
+   - \ref stream_seeking
+
+   Several additional sections are not tied to the main API.
+   - \ref stream_callbacks
+   - \ref header_info
+   - \ref error_codes
+
+   \section Overview
+
+   The <tt>libopusfile</tt> API always decodes files to 48&nbsp;kHz.
+   The original sample rate is not preserved by the lossy compression, though
+    it is stored in the header to allow you to resample to it after decoding
+    (the <tt>libopusfile</tt> API does not currently provide a resampler,
+    but the
+    <a href="http://www.speex.org/docs/manual/speex-manual/node7.html#SECTION00760000000000000000">the
+    Speex resampler</a> is a good choice if you need one).
+   In general, if you are playing back the audio, you should leave it at
+    48&nbsp;kHz, provided your audio hardware supports it.
+   When decoding to a file, it may be worth resampling back to the original
+    sample rate, so as not to surprise users who might not expect the sample
+    rate to change after encoding to Opus and decoding.
+
+   Opus files can contain anywhere from 1 to 255 channels of audio.
+   The channel mappings for up to 8 channels are the same as the
+    <a href="http://www.xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-800004.3.9">Vorbis
+    mappings</a>.
+   A special stereo API can convert everything to 2 channels, making it simple
+    to support multichannel files in an application which only has stereo
+    output.
+   Although the <tt>libopusfile</tt> ABI provides support for the theoretical
+    maximum number of channels, the current implementation does not support
+    files with more than 8 channels, as they do not have well-defined channel
+    mappings.
+
+   Like all Ogg files, Opus files may be "chained".
+   That is, multiple Opus files may be combined into a single, longer file just
+    by concatenating the original files.
+   This is commonly done in internet radio streaming, as it allows the title
+    and artist to be updated each time the song changes, since each link in the
+    chain includes its own set of metadata.
+
+   <tt>libopusfile</tt> fully supports chained files.
+   It will decode the first Opus stream found in each link of a chained file
+    (ignoring any other streams that might be concurrently multiplexed with it,
+    such as a video stream).
+
+   The channel count can also change between links.
+   If your application is not prepared to deal with this, it can use the stereo
+    API to ensure the audio from all links will always get decoded into a
+    common format.
+   Since <tt>libopusfile</tt> always decodes to 48&nbsp;kHz, you do not have to
+    worry about the sample rate changing between links (as was possible with
+    Vorbis).
+   This makes application support for chained files with <tt>libopusfile</tt>
+    very easy.*/

+   The number of channels returned can change from link to link in a chained

-  This is a version (aka dlmalloc) of malloc/free/realloc written by
-  Doug Lea and released to the public domain, as explained at
-  http://creativecommons.org/licenses/publicdomain.  Send questions,
-  comments, complaints, performance data, etc to dl@cs.oswego.edu
-
-* Version 2.8.4 Wed May 27 09:56:23 2009  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-2.8.4.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 nedmalloc
-       (http://www.nedprod.com/programs/portable/nedmalloc/) or
-       ptmalloc (See http://www.malloc.de), which are derived
-       from versions of this malloc.
-
-  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. In real-time
-  applications, you can optionally suppress segment traversals using
-  NO_SEGMENT_TRAVERSAL, which assures bounded execution even when
-  system allocators return non-contiguous spaces, at the typical
-  expense of carrying around more memory and increased fragmentation.
-
-  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. You can also
-use the symbolic values MAX_SIZE_T, SIZE_T_ONE, etc below.
-
-WIN32                    default: defined if _WIN32 defined
-  Defining WIN32 sets up defaults for MS environment and compilers.
-  Otherwise defaults are for unix. Beware that there seem to be some
-  cases where this malloc might not be a pure drop-in replacement for
-  Win32 malloc: Random-looking failures from Win32 GDI API's (eg;
-  SetDIBits()) may be due to bugs in some video driver implementations
-  when pixel buffers are malloc()ed, and the region spans more than
-  one VirtualAlloc()ed region. Because dlmalloc uses a small (64Kb)
-  default granularity, pixel buffers may straddle virtual allocation
-  regions more often than when using the Microsoft allocator.  You can
-  avoid this by using VirtualAlloc() and VirtualFree() for all pixel
-  buffers rather than using malloc().  If this is not possible,
-  recompile this malloc with a larger DEFAULT_GRANULARITY.
-
-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.) If set to a
-  non-zero value other than 1, locks are used, but their
-  implementation is left out, so lock functions must be supplied manually,
-  as described below.
-
-USE_SPIN_LOCKS           default: 1 iff USE_LOCKS and on x86 using gcc or MSC
-  If true, uses custom spin locks for locking. This is currently
-  supported only for x86 platforms using gcc or recent MS compilers.
-  Otherwise, posix locks or win32 critical sections are used.
-
-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.
-
-MORECORE_CONTIGUOUS       default: 1 (true) if HAVE_MORECORE
-  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.
-
-NO_SEGMENT_TRAVERSAL       default: 0
-  If non-zero, suppresses traversals of memory segments
-  returned by either MORECORE or CALL_MMAP. This disables
-  merging of segments that are contiguous, and selectively
-  releasing them to the OS if unused, but bounds execution times.
-
-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 except on WINCE.
-  True if mmap clears memory so calloc doesn't need to. This is true
-  for standard unix mmap using /dev/zero and on WIN32 except for WINCE.
-
-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. Similarly for Win32 under recent MS compilers.
-  (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. This may be several megabytes if ENABLE_LARGE_PAGES
-  is enabled.
-
-ENABLE_LARGE_PAGES         default: NOT defined
-  Causes the system page size to be the value of GetLargePageMinimum()
-  if that function is available (Windows Server 2003/Vista or later).
-  This allows the use of large page entries in the MMU which can
-  significantly improve performance in large working set applications
-  as TLB cache load is reduced by a factor of three. Note that enabling
-  this option is equal to locking the process' memory in current
-  implementations of Windows and requires the SE_LOCK_MEMORY_PRIVILEGE
-  to be held by the process in order to succeed.
-
-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,
-                                GetLargePageMinimum() if ENABLE_LARGE_PAGES,
-                                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_GRANULARITY_ALIGNED default: undefined (which means page size)
-  Whether to enforce alignment when allocating and deallocating memory
-  from the system i.e. the base address of all allocations will be
-  aligned to DEFAULT_GRANULARITY if it is set. Note that enabling this carries
-  some overhead as multiple calls must now be made when probing for a valid
-  aligned value, however it does greatly ease the checking for whether
-  a given memory pointer was allocated by this allocator rather than
-  some other.
-
-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.
-
-MAX_RELEASE_CHECK_RATE   default: 4095 unless not HAVE_MMAP
-  The number of consolidated frees between checks to release
-  unused segments when freeing. When using non-contiguous segments,
-  especially with multiple mspaces, checking only for topmost space
-  doesn't always suffice to trigger trimming. To compensate for this,
-  free() will, with a period of MAX_RELEASE_CHECK_RATE (or the
-  current number of segments, if greater) try to release unused
-  segments to the OS when freeing chunks that result in
-  consolidation. The best value for this parameter is a compromise
-  between slowing down frees with relatively costly checks that
-  rarely trigger versus holding on to unused memory. To effectively
-  disable, set to MAX_SIZE_T. This may lead to a very slight speed
-  improvement at the expense of carrying around more memory.

-  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

-  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

-  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

-/* --------------------------- Lock preliminaries ------------------------ */

-/*
-  When locks are defined, there is one global lock, plus
-  one per-mspace lock.
-
-  The global lock_ensures that mparams.magic and other unique
-  mparams values are initialized only once. It also protects
-  sequences of calls to MORECORE.  In many cases sys_alloc requires
-  two calls, that should not be interleaved with calls by other
-  threads.  This does not protect against direct calls to MORECORE
-  by other threads not using this lock, so there is still code to
-  cope the best we can on interference.
-
-  Per-mspace locks surround calls to malloc, free, etc.  To enable use
-  in layered extensions, per-mspace locks are reentrant.
-
-  Because lock-protected regions generally have bounded times, it is
-  OK to use the supplied simple spinlocks in the custom versions for
-  x86. Spinlocks are likely to improve performance for lightly
-  contended applications, but worsen performance under heavy
-  contention.
-
-  If USE_LOCKS is > 1, the definitions of lock routines here are
-  bypassed, in which case you will need to define the type MLOCK_T,
-  and at least INITIAL_LOCK, ACQUIRE_LOCK, RELEASE_LOCK and possibly
-  TRY_LOCK (which is not used in this malloc, but commonly needed in
-  extensions.)  You must also declare a
-    static MLOCK_T malloc_global_mutex = { initialization values };.

-  (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-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

-  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 (unless the chunk is mmapped). 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.
-
-     3. Chunks allocated via mmap, have both cinuse and pinuse bits
-        cleared in their head fields.  Because they are allocated
-        one-by-one, each must carry its own prev_foot field, which is
-        also used to hold the offset this chunk has within its mmapped
-        region, which is needed to preserve alignment. Each mmapped
-        chunk is trailed by the first two fields of a fake next-chunk
-        for sake of usage checks.

-
-  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 USE_MMAP_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.

-/* ---------------------------- malloc_state ----------------------------- */
-
-/*
-   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.
-
-  Trim support
-    Fields holding the amount of unused topmost memory that should trigger
-    timming, and a counter to force periodic scanning to release unused
-    non-topmost segments.
-
-  Locking
-    If USE_LOCKS is defined, the "mutex" lock is acquired and released
-    around every public call using this mspace.
-
-  Extension support
-    A void* pointer and a size_t field that can be used to help implement
-    extensions to this malloc.

-  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;
-    }
-    else if (size < 0)
-    {
-      // we don't currently support shrink behavior
-      return (void *) MFAIL;

-
-  void osCleanupMem(void)

+
+* Version 2.8.4 Wed May 27 09:56:23 2009  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-2.8.4.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 nedmalloc
+       (http://www.nedprod.com/programs/portable/nedmalloc/) or
+       ptmalloc (See http://www.malloc.de), which are derived
+       from versions of this malloc.
+
+  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. In real-time
+  applications, you can optionally suppress segment traversals using
+  NO_SEGMENT_TRAVERSAL, which assures bounded execution even when
+  system allocators return non-contiguous spaces, at the typical
+  expense of carrying around more memory and increased fragmentation.
+
+  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. You can also
+use the symbolic values MAX_SIZE_T, SIZE_T_ONE, etc below.
+
+WIN32                    default: defined if _WIN32 defined
+  Defining WIN32 sets up defaults for MS environment and compilers.
+  Otherwise defaults are for unix. Beware that there seem to be some
+  cases where this malloc might not be a pure drop-in replacement for
+  Win32 malloc: Random-looking failures from Win32 GDI API's (eg;
+  SetDIBits()) may be due to bugs in some video driver implementations
+  when pixel buffers are malloc()ed, and the region spans more than
+  one VirtualAlloc()ed region. Because dlmalloc uses a small (64Kb)
+  default granularity, pixel buffers may straddle virtual allocation
+  regions more often than when using the Microsoft allocator.  You can
+  avoid this by using VirtualAlloc() and VirtualFree() for all pixel
+  buffers rather than using malloc().  If this is not possible,
+  recompile this malloc with a larger DEFAULT_GRANULARITY.
+
+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.) If set to a
+  non-zero value other than 1, locks are used, but their
+  implementation is left out, so lock functions must be supplied manually,
+  as described below.
+
+USE_SPIN_LOCKS           default: 1 iff USE_LOCKS and on x86 using gcc or MSC
+  If true, uses custom spin locks for locking. This is currently
+  supported only for x86 platforms using gcc or recent MS compilers.
+  Otherwise, posix locks or win32 critical sections are used.
+
+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.
+
+MORECORE_CONTIGUOUS       default: 1 (true) if HAVE_MORECORE
+  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.
+
+NO_SEGMENT_TRAVERSAL       default: 0
+  If non-zero, suppresses traversals of memory segments
+  returned by either MORECORE or CALL_MMAP. This disables
+  merging of segments that are contiguous, and selectively
+  releasing them to the OS if unused, but bounds execution times.
+
+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 except on WINCE.
+  True if mmap clears memory so calloc doesn't need to. This is true
+  for standard unix mmap using /dev/zero and on WIN32 except for WINCE.
+
+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. Similarly for Win32 under recent MS compilers.
+  (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. This may be several megabytes if ENABLE_LARGE_PAGES
+  is enabled.
+
+ENABLE_LARGE_PAGES         default: NOT defined
+  Causes the system page size to be the value of GetLargePageMinimum()
+  if that function is available (Windows Server 2003/Vista or later).
+  This allows the use of large page entries in the MMU which can
+  significantly improve performance in large working set applications
+  as TLB cache load is reduced by a factor of three. Note that enabling
+  this option is equal to locking the process' memory in current
+  implementations of Windows and requires the SE_LOCK_MEMORY_PRIVILEGE
+  to be held by the process in order to succeed.
+
+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

+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.

+                                system_info.dwAllocationGranularity in WIN32,

+      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_GRANULARITY_ALIGNED default: undefined (which means page size)
+  Whether to enforce alignment when allocating and deallocating memory
+  from the system i.e. the base address of all allocations will be
+  aligned to DEFAULT_GRANULARITY if it is set. Note that enabling this carries
+  some overhead as multiple calls must now be made when probing for a valid
+  aligned value, however it does greatly ease the checking for whether
+  a given memory pointer was allocated by this allocator rather than
+  some other.
+
+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.
+
+MAX_RELEASE_CHECK_RATE   default: 4095 unless not HAVE_MMAP
+  The number of consolidated frees between checks to release
+  unused segments when freeing. When using non-contiguous segments,
+  especially with multiple mspaces, checking only for topmost space
+  doesn't always suffice to trigger trimming. To compensate for this,
+  free() will, with a period of MAX_RELEASE_CHECK_RATE (or the
+  current number of segments, if greater) try to release unused
+  segments to the OS when freeing chunks that result in
+  consolidation. The best value for this parameter is a compromise
+  between slowing down frees with relatively costly checks that
+  rarely trigger versus holding on to unused memory. To effectively
+  disable, set to MAX_SIZE_T. This may lead to a very slight speed
+  improvement at the expense of carrying around more memory.

+  independent_calloc is similar to calloc, but instead of returning a

+  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

+  independently free elements.)

+  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:

+  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) {
+    int msglen = strlen(msg);
+    size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) };
+    void* chunks[3];
+    if (independent_comalloc(3, sizes, chunks) == 0)
+      die();
+    struct Head* head = (struct Head*)(chunks[0]);
+    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.
+
+  Overuse of independent_comalloc can increase overall memory usage,
+  since it cannot reuse existing noncontiguous small chunks that
+  might be available for some of the elements.

+

+/*
+  When locks are defined, there is one global lock, plus
+  one per-mspace lock.
+
+  The global lock_ensures that mparams.magic and other unique
+  mparams values are initialized only once. It also protects
+  sequences of calls to MORECORE.  In many cases sys_alloc requires
+  two calls, that should not be interleaved with calls by other
+  threads.  This does not protect against direct calls to MORECORE
+  by other threads not using this lock, so there is still code to
+  cope the best we can on interference.
+
+  Per-mspace locks surround calls to malloc, free, etc.  To enable use
+  in layered extensions, per-mspace locks are reentrant.
+
+  Because lock-protected regions generally have bounded times, it is
+  OK to use the supplied simple spinlocks in the custom versions for
+  x86. Spinlocks are likely to improve performance for lightly
+  contended applications, but worsen performance under heavy
+  contention.
+
+  If USE_LOCKS is > 1, the definitions of lock routines here are
+  bypassed, in which case you will need to define the type MLOCK_T,
+  and at least INITIAL_LOCK, ACQUIRE_LOCK, RELEASE_LOCK and possibly
+  TRY_LOCK (which is not used in this malloc, but commonly needed in
+  extensions.)  You must also declare a
+    static MLOCK_T malloc_global_mutex = { initialization values };.

+  (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 = 0)                             |

+  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 (unless the chunk is mmapped). 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.
+
+     3. Chunks allocated via mmap, have both cinuse and pinuse bits
+        cleared in their head fields.  Because they are allocated
+        one-by-one, each must carry its own prev_foot field, which is
+        also used to hold the offset this chunk has within its mmapped
+        region, which is needed to preserve alignment. Each mmapped
+        chunk is trailed by the first two fields of a fake next-chunk
+        for sake of usage checks.

+
+  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 USE_MMAP_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.
+
+  Trim support
+    Fields holding the amount of unused topmost memory that should trigger
+    timming, and a counter to force periodic scanning to release unused
+    non-topmost segments.
+
+  Locking
+    If USE_LOCKS is defined, the "mutex" lock is acquired and released
+    around every public call using this mspace.
+
+  Extension support
+    A void* pointer and a size_t field that can be used to help implement
+    extensions to this malloc.

+  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)

+        Thanks also to Andreas Mueller <a.mueller at paradatec.de>,
+        and Anonymous.
+      * Allow override of MALLOC_ALIGNMENT (Thanks to Ruud Waij for
+        helping test this.)
+      * memalign: check alignment arg
+      * realloc: don't try to shift chunks backwards, since this
+        leads to  more fragmentation in some programs and doesn't
+        seem to help in any others.
+      * Collect all cases in malloc requiring system memory into sysmalloc
+      * Use mmap as backup to sbrk
+      * Place all internal state in malloc_state
+      * Introduce fastbins (although similar to 2.5.1)
+      * Many minor tunings and cosmetic improvements
+      * Introduce USE_PUBLIC_MALLOC_WRAPPERS, USE_MALLOC_LOCK
+      * Introduce MALLOC_FAILURE_ACTION, MORECORE_CONTIGUOUS
+        Thanks to Tony E. Bennett <tbennett@nvidia.com> and others.
+      * Include errno.h to support default failure action.
+
+    V2.6.6 Sun Dec  5 07:42:19 1999  Doug Lea  (dl at gee)
+      * return null for negative arguments
+      * Added Several WIN32 cleanups from Martin C. Fong <mcfong at yahoo.com>
+         * Add 'LACKS_SYS_PARAM_H' for those systems without 'sys/param.h'
+          (e.g. WIN32 platforms)
+         * Cleanup header file inclusion for WIN32 platforms
+         * Cleanup code to avoid Microsoft Visual C++ compiler complaints
+         * Add 'USE_DL_PREFIX' to quickly allow co-existence with existing
+           memory allocation routines
+         * Set 'malloc_getpagesize' for WIN32 platforms (needs more work)
+         * Use 'assert' rather than 'ASSERT' in WIN32 code to conform to
+           usage of 'assert' in non-WIN32 code
+         * Improve WIN32 'sbrk()' emulation's 'findRegion()' routine to
+           avoid infinite loop
+      * Always call 'fREe()' rather than 'free()'
+
+    V2.6.5 Wed Jun 17 15:57:31 1998  Doug Lea  (dl at gee)
+      * Fixed ordering problem with boundary-stamping
+
+    V2.6.3 Sun May 19 08:17:58 1996  Doug Lea  (dl at gee)
+      * Added pvalloc, as recommended by H.J. Liu
+      * Added 64bit pointer support mainly from Wolfram Gloger
+      * Added anonymously donated WIN32 sbrk emulation
+      * Malloc, calloc, getpagesize: add optimizations from Raymond Nijssen
+      * malloc_extend_top: fix mask error that caused wastage after
+        foreign sbrks
+      * Add linux mremap support code from HJ Liu
+
+    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).
+      * Use last_remainder in more cases.
+      * Pack bins using idea from  colin@nyx10.cs.du.edu
+      * Use ordered bins instead of best-fit threshhold
+      * Eliminate block-local decls to simplify tracing and debugging.
+      * Support another case of realloc via move into top
+      * Fix error occuring when initial sbrk_base not word-aligned.
+      * Rely on page size for units instead of SBRK_UNIT to
+        avoid surprises about sbrk alignment conventions.
+      * Add mallinfo, mallopt. Thanks to Raymond Nijssen
+        (raymond@es.ele.tue.nl) for the suggestion.
+      * 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)
+      * Removed footers when chunks are in use. Thanks to
+        Paul Wilson (wilson@cs.texas.edu) for the suggestion.
+
+    V2.5.4 Wed Nov  1 07:54:51 1995  Doug Lea  (dl at gee)
+      * Added malloc_trim, with help from Wolfram Gloger
+        (wmglo@Dent.MED.Uni-Muenchen.DE).
+
+    V2.5.3 Tue Apr 26 10:16:01 1994  Doug Lea  (dl at g)
+
+    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
+
+    V2.5 Sat Aug  7 07:41:59 1993  Doug Lea  (dl at g.oswego.edu)
+      * 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.)

-/* See malloc.c.h for what each function does.
-
-REPLACE_SYSTEM_ALLOCATOR on POSIX causes nedalloc's functions to be called
-malloc, free etc. instead of nedmalloc, nedfree etc. You may or may not want
-this. On Windows it causes nedmalloc to patch all loaded DLLs and binaries
-to replace usage of the system allocator.
-
-NO_NED_NAMESPACE prevents the functions from being defined in the nedalloc
-namespace when in C++ (uses the global namespace instead).
-
-NEDMALLOCEXTSPEC can be defined to be __declspec(dllexport) or
-__attribute__ ((visibility("default"))) or whatever you like. It defaults
-to extern unless NEDMALLOC_DLL_EXPORTS is set as it would be when building
-nedmalloc.dll.
-
-USE_LOCKS can be 2 if you want to define your own MLOCK_T, INITIAL_LOCK,
-ACQUIRE_LOCK, RELEASE_LOCK, TRY_LOCK, IS_LOCKED and NULL_LOCK_INITIALIZER.
-
-NEDMALLOC_DEBUG can be defined to cause DEBUG to be set differently for nedmalloc
-than for the rest of the build. Remember to set NDEBUG to disable all assertion
-checking too.
-
-USE_MAGIC_HEADERS causes nedalloc to allocate an extra three sizeof(size_t)
-to each block. nedpfree() and nedprealloc() can then automagically know when
-to free a system allocated block. Enabling this typically adds 20-50% to
-application memory usage.
-
-ENABLE_TOLERANT_NEDMALLOC is automatically turned on if REPLACE_SYSTEM_ALLOCATOR
-is set or the Windows DLL is being built. This causes nedmalloc to detect when a
-system allocator block is passed to it and to handle it appropriately. Note that
-without USE_MAGIC_HEADERS there is a very tiny chance that nedmalloc will segfault
-on non-Windows builds (it uses Win32 SEH to trap segfaults on Windows and there
-is no comparable system on POSIX).
-
-USE_ALLOCATOR can be one of these settings (it defaults to 1):
-  0: System allocator (nedmalloc now simply acts as a threadcache).
-     WARNING: Intended for DEBUG USE ONLY - not all functions work correctly.
-  1: dlmalloc
-
-ENABLE_LARGE_PAGES enables support for requesting memory from the system in large
-(typically >=2Mb) pages if the host OS supports this. These occupy just a single
-TLB entry and can significantly improve performance in large working set applications.
-
-ENABLE_FAST_HEAP_DETECTION enables special logic to detect blocks allocated
-by the system heap. This avoids 1.5%-2% overhead when checking for non-nedmalloc
-blocks, but it assumes that the NT and glibc heaps function in a very specific
-fashion which may not hold true across OS upgrades.

-// JACK is a low-latency audio server, originally written for the
-// GNU/Linux operating system and now also ported to OS-X. It can
-// connect a number of different applications to an audio device, as
-// well as allowing them to share audio between themselves.
-//
-// When using JACK with RtAudio, "devices" refer to JACK clients that
-// have ports connected to the server.  The JACK server is typically
-// started in a terminal as follows:
-//
-// .jackd -d alsa -d hw:0
-//
-// or through an interface program such as qjackctl.  Many of the
-// parameters normally set for a stream are fixed by the JACK server
-// and can be specified when the JACK server is started.  In
-// particular,
-//
-// .jackd -d alsa -d hw:0 -r 44100 -p 512 -n 4
-//
-// specifies a sample rate of 44100 Hz, a buffer size of 512 sample
-// frames, and number of buffers = 4.  Once the server is running, it
-// is not possible to override these values.  If the values are not
-// specified in the command-line, the JACK server uses default values.
-//
-// The JACK server does not have to be running when an instance of
-// RtApiJack is created, though the function getDeviceCount() will
-// report 0 devices found until JACK has been started.  When no
-// devices are available (i.e., the JACK server is not running), a
-// stream cannot be opened.

-#if defined(__WINDOWS_ASIO__) // ASIO API on Windows
-
-// The ASIO API is designed around a callback scheme, so this
-// implementation is similar to that used for OS-X CoreAudio and Linux
-// Jack.  The primary constraint with ASIO is that it only allows
-// access to a single driver at a time.  Thus, it is not possible to
-// have more than one simultaneous RtAudio stream.
-//
-// This implementation also requires a number of external ASIO files
-// and a few global variables.  The ASIO callback scheme does not
-// allow for the passing of user data, so we must create a global
-// pointer to our callbackInfo structure.
-//
-// On unix systems, we make use of a pthread condition variable.
-// Since there is no equivalent in Windows, I hacked something based
-// on information found in
-// http://www.cs.wustl.edu/~schmidt/win32-cv-1.html.

+// JACK is a low-latency audio server, originally written for the
+// GNU/Linux operating system and now also ported to OS-X. It can
+// connect a number of different applications to an audio device, as
+// well as allowing them to share audio between themselves.
+//
+// When using JACK with RtAudio, "devices" refer to JACK clients that
+// have ports connected to the server.  The JACK server is typically
+// started in a terminal as follows:
+//
+// .jackd -d alsa -d hw:0
+//
+// or through an interface program such as qjackctl.  Many of the
+// parameters normally set for a stream are fixed by the JACK server
+// and can be specified when the JACK server is started.  In
+// particular,
+//
+// .jackd -d alsa -d hw:0 -r 44100 -p 512 -n 4
+//
+// specifies a sample rate of 44100 Hz, a buffer size of 512 sample
+// frames, and number of buffers = 4.  Once the server is running, it
+// is not possible to override these values.  If the values are not
+// specified in the command-line, the JACK server uses default values.
+//
+// The JACK server does not have to be running when an instance of
+// RtApiJack is created, though the function getDeviceCount() will
+// report 0 devices found until JACK has been started.  When no
+// devices are available (i.e., the JACK server is not running), a
+// stream cannot be opened.
