++ This is a version (aka dlmalloc) of malloc/free/realloc written by
++ Doug Lea and released to the public domain. Use, modify, and
++ redistribute this code without permission or acknowledgment in any
++ way you wish. Send questions, comments, complaints, performance
++ data, etc to dl@cs.oswego.edu
++
++* VERSION 2.7.0 Sun Mar 11 14:14:06 2001 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 (-O), and link it into another program. All
++ of the compile-time options default to reasonable values for use on
++ most unix platforms. Compile -DWIN32 for reasonable defaults on windows.
++ 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-2.7.0.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.
++
++* Why use this malloc?
++
++ 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.
++
++ The main properties of the algorithms are:
++ * For large (>= 512 bytes) requests, it is a pure best-fit allocator,
++ with ties normally decided via FIFO (i.e. least recently used).
++ * For small (<= 64 bytes by default) requests, it is a caching
++ allocator, that maintains pools of quickly recycled chunks.
++ * In between, and for combinations of large and small requests, it does
++ the best it can trying to meet both goals at once.
++ * For very large requests (>= 128KB by default), it relies on system
++ memory mapping facilities, if supported.
++
++ For a longer but slightly out of date high-level description, see
++ http://gee.cs.oswego.edu/dl/html/malloc.html
++
++ 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 in order to
++ customize settings or to avoid overheads associated with library
++ versions.
++
++* Contents, described in more detail in "description of public routines" below.
++
++ Standard (ANSI/SVID/...) functions:
++ malloc(size_t n);
++ calloc(size_t n_elements, size_t element_size);
++ free(Void_t* p);
++ realloc(Void_t* p, size_t n);
++ memalign(size_t alignment, size_t n);
++ valloc(size_t n);
++ mallinfo()
++ mallopt(int parameter_number, int parameter_value)
++
++ Additional functions:
++ independent_calloc(size_t n_elements, size_t size, Void_t* chunks[]);
++ independent_comalloc(size_t n_elements, size_t sizes[], Void_t* chunks[]);
++ pvalloc(size_t n);
++ cfree(Void_t* p);
++ malloc_trim(size_t pad);
++ malloc_usable_size(Void_t* p);
++ malloc_stats();
++
++* Vital statistics:
++
++ Supported pointer representation: 4 or 8 bytes
++ Supported size_t representation: 4 or 8 bytes
++ Note that size_t is allowed to be 4 bytes even if pointers are 8.
++ You can adjust this by defining INTERNAL_SIZE_T
++
++ Alignment: 2 * sizeof(size_t) (default)
++ (i.e., 8 byte alignment with 4byte size_t). This suffices for
++ nearly all current machines and C compilers. However, you can
++ define MALLOC_ALIGNMENT to be wider than this if necessary.
++
++ Minimum overhead per allocated chunk: 4 or 8 bytes
++ Each malloced chunk has a hidden word of overhead holding size
++ and status information.
++
++ Minimum allocated size: 4-byte ptrs: 16 bytes (including 4 overhead)
++ 8-byte ptrs: 24/32 bytes (including, 4/8 overhead)
++
++ When a chunk is freed, 12 (for 4byte ptrs) or 20 (for 8 byte
++ ptrs but 4 byte size) or 24 (for 8/8) additional bytes are
++ needed; 4 (8) for a trailing size field and 8 (16) bytes for
++ free list pointers. Thus, the minimum allocatable size is
++ 16/24/32 bytes.
++
++ 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 2 *
++ sizeof(size_t) bytes plus the remainder from a system page (the
++ minimal mmap unit); typically 4096 or 8192 bytes.
++
++ Maximum allocated size: 4-byte size_t: 2^32 minus about two pages
++ 8-byte size_t: 2^64 minus about two pages
++
++ It is assumed that (possibly signed) size_t values suffice to
++ represent chunk sizes. `Possibly signed' is due to the fact
++ that `size_t' may be defined on a system as either a signed or
++ an unsigned type. The ISO C standard says that it must be
++ unsigned, but a few systems are known not to adhere to this.
++ Additionally, even when size_t is unsigned, sbrk (which is by
++ default used to obtain memory from system) accepts signed
++ arguments, and may not be able to handle size_t-wide arguments
++ with negative sign bit. Generally, values that would
++ appear as negative after accounting for overhead and alignment
++ are supported only via mmap(), which does not have this
++ limitation.
++
++ Requests for sizes outside the allowed range will perform an optional
++ failure action and then return null. (Requests may also
++ also fail because a system is out of memory.)
++
++ Thread-safety: NOT thread-safe unless USE_MALLOC_LOCK defined
++
++ When USE_MALLOC_LOCK is defined, wrappers are created to
++ surround every public call 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,
++ you would be far better off obtaining ptmalloc, which is
++ derived from a version of this malloc, and is well-tuned for
++ concurrent programs. (See http://www.malloc.de)
++
++ Compliance: I believe it is compliant with the 1997 Single Unix Specification
++ (See http://www.opennc.org). Also SVID/XPG, ANSI C, and probably
++ others as well.
++
++* Synopsis of compile-time options:
++
++ People have reported using previous versions of this malloc on all
++ versions of Unix, sometimes by tweaking some of the defines
++ below. It has been tested most extensively on Solaris and
++ Linux. It is also reported to work on WIN32 platforms.
++ People also report using it in stand-alone embedded systems.
++
++ The implementation is in straight, hand-tuned ANSI C. It is not
++ at all modular. (Sorry!) It uses a lot of macros. To be at all
++ usable, this code should be compiled using an optimizing compiler
++ (for example gcc -O3) that can simplify expressions and control
++ paths. (FAQ: some macros import variables as arguments rather than
++ declare locals because people reported that some debuggers
++ otherwise get confused.)

++ Debugging:
++
++ Because freed chunks may be overwritten with bookkeeping fields, this
++ malloc will often die when freed memory is overwritten by user
++ programs. This can be very effective (albeit in an annoying way)
++ in helping track down dangling pointers.
++
++ If you compile with -DDEBUG, a number of assertion checks are

++ should help you locate incorrectly overwritten memory. 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 summmaries. (By nature, mmapped regions
++ cannot be checked very much automatically.)
++
++ Setting DEBUG may also be helpful if you are trying to modify
++ this code. The assertions in the check routines spell out in more
++ detail the assumptions and invariants underlying the algorithms.
++
++ Setting DEBUG does NOT provide an automated mechanism for checking
++ that all accesses to malloced memory stay within their
++ bounds. However, there are several add-ons and adaptations of this
++ or other mallocs available that do this.

++
++ On a 64-bit machine, you may be able to reduce malloc overhead by

++ - INTERNAL_SIZE_T might be signed or unsigned, might be 32 or 64 bits,
++ and might be the same width as int or as long
++ - size_t might have different width and signedness as INTERNAL_SIZE_T
++ - int and long might be 32 or 64 bits, and might be the same width
++ To deal with this, most comparisons and difference computations
++ among INTERNAL_SIZE_Ts should cast them to unsigned long, being

++ M_TRIM_THRESHOLD is 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.
++ 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.
++
++ The trim threshold and the mmap control parameters (see below)
++ can be traded off with one another. Trimming and mmapping are
++ two different ways of releasing unused memory back to the
++ system. Between these two, it is often possible to keep
++ system-level demands of a long-lived program down to a bare
++ minimum. For example, in one test suite of sessions measuring
++ the XF86 X server on Linux, using a trim threshold of 128K and a
++ mmap threshold of 192K led to near-minimal long term resource
++ consumption.
++
++ If you are using this malloc in a long-lived program, it should
++ pay to experiment with these values. 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's
++ worth it to tune for trimming rather tham memory mapping 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. And in well-behaved long-lived programs,
++ controlling release of large blocks via trimming versus mapping
++ is usually faster.
++
++ However, in most programs, these parameters serve mainly as
++ protection against the system-level effects of carrying around
++ massive amounts of unneeded memory. Since frequent calls to
++ sbrk, mmap, and munmap otherwise degrade performance, the default
++ parameters are set to relatively high values that serve only as
++ safeguards.
++
++ The trim value It must be greater than page size to have any useful
++ effect. To disable trimming completely, you can set to
++ (unsigned long)(-1)
++
++ Trim settings interact with fastbin (MXFAST) settings: Unless
++ TRIM_FASTBINS is defined, automatic trimming never takes place upon
++ freeing a chunk with size less than or equal to MXFAST. Trimming is
++ instead delayed until subsequent freeing of larger chunks. However,
++ you can still force an attempted trim by calling malloc_trim.
++
++ Also, trimming is not generally possible in cases where
++ the main arena is obtained via mmap.
++
++ 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.

++ malloc_chunk details:
++
++ (The following includes lightly edited explanations by Colin Plumb.)
++
++ Chunks of memory are maintained using a `boundary tag' method as
++ described in e.g., Knuth or Standish. (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 very fast. The
++ size fields also hold bits representing whether chunks are free or
++ in use.
++
++ An allocated chunk looks like this:
++
++
++ chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
++ | Size of previous chunk, if allocated | |
++ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
++ | Size of chunk, in bytes |P|
++ mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
++ | User data starts here... .
++ . .
++ . (malloc_usable_space() bytes) .
++ . |
++nextchunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
++ | Size of chunk |
++ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
++
++
++ Where "chunk" is the front of the chunk for the purpose of most of
++ the malloc code, but "mem" is the pointer that is returned to the
++ user. "Nextchunk" is the beginning of the next contiguous 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.
++
++ Free chunks are stored in circular doubly-linked lists, and look like this:
++
++ chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
++ | Size of previous chunk |
++ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
++ `head:' | Size of chunk, in bytes |P|
++ mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
++ | Forward pointer to next chunk in list |
++ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
++ | Back pointer to previous chunk in list |
++ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
++ | Unused space (may be 0 bytes long) .
++ . .
++ . |
++nextchunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
++ `foot:' | Size of chunk, in bytes |
++ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
++
++ The P (PREV_INUSE) 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
++ prev_inuse 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.
++
++ Note that the `foot' of the current chunk is actually represented
++ as the prev_size 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 two exceptions to all this are
++
++ 1. The special chunk `top' doesn't bother using the
++ trailing size field since there is no next contiguous chunk
++ that would have to index off it. After initialization, `top'
++ is forced to always exist. If it would become less than
++ MINSIZE bytes long, it is replenished.
++
++ 2. Chunks allocated via mmap, which have the second-lowest-order
++ bit (IS_MMAPPED) set in their size fields. Because they are
++ allocated one-by-one, each must contain its own trailing size field.

++ Bins
++
++ An array of bin headers for free chunks. Each bin is doubly
++ linked. The bins are approximately proportionally (log) spaced.
++ There are a lot of these bins (128). This may look excessive, but
++ works very well in practice. Most bins hold sizes that are
++ unusual as malloc request sizes, but are more usual for fragments
++ and consolidated sets of chunks, which is what these bins hold, so
++ they can be found quickly. All procedures maintain the invariant
++ that no consolidated chunk physically borders another one, so each
++ chunk in a list is known to be preceded and followed by either
++ inuse chunks or the ends of memory.
++
++ Chunks in bins are kept in size order, with ties going to the
++ approximately least recently used chunk. Ordering isn't needed
++ for the small bins, which all contain the same-sized chunks, but
++ facilitates best-fit allocation for larger chunks. These lists
++ are just sequential. Keeping them in order almost never requires
++ enough traversal to warrant using fancier ordered data
++ structures.
++
++ Chunks of the same size are linked with the most
++ recently freed at the front, and allocations are taken from the
++ back. This results in LRU (FIFO) allocation order, which tends
++ to give each chunk an equal opportunity to be consolidated with
++ adjacent freed chunks, resulting in larger free chunks and less
++ fragmentation.
++
++ To simplify use in double-linked lists, each bin header acts
++ as a malloc_chunk. This avoids special-casing for headers.
++ But to conserve space and improve locality, we allocate
++ only the fd/bk pointers of bins, and then use repositioning tricks
++ to treat these as the fields of a malloc_chunk*.

++ -------------------- Alternative MORECORE functions --------------------
++*/
++
++
++/*
++ General Requirements for MORECORE.
++
++ The MORECORE function must have the following properties:
++
++ If MORECORE_CONTIGUOUS is false:
++
++ * MORECORE must allocate in multiples of pagesize. It will
++ only be called with arguments that are multiples of pagesize.
++
++ * MORECORE(0) must return an address that is at least
++ MALLOC_ALIGNMENT aligned. (Page-aligning always suffices.)
++
++ else (i.e. If MORECORE_CONTIGUOUS is true):
++
++ * Consecutive calls to MORECORE with positive arguments
++ return increasing addresses, indicating that space has been
++ contiguously extended.
++
++ * MORECORE need not allocate in multiples of pagesize.
++ Calls to MORECORE need not have args of multiples of pagesize.
++
++ * MORECORE need not page-align.
++
++ In either case:
++
++ * MORECORE may allocate more memory than requested. (Or even less,
++ but this will generally 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. This malloc does NOT call MORECORE(0)
++ until at least one call with positive arguments is made, so
++ the initial value returned is not important.
++
++ * 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 MORECORE_FAILURE 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,
++
++ There is some variation across systems about the type of the
++ argument to sbrk/MORECORE. If size_t is unsigned, then it cannot
++ actually be size_t, because sbrk supports negative args, so it is
++ normally the signed type of the same width as size_t (sometimes
++ declared as "intptr_t", and sometimes "ptrdiff_t"). It doesn't much
++ matter though. Internally, we use "long" as arguments, which should
++ work across all reasonable possibilities.
++
++ Additionally, if MORECORE ever returns failure for a positive
++ request, and HAVE_MMAP is true, then mmap is used as a noncontiguous
++ system allocator. This is a useful backup strategy for systems with
++ holes in address spaces -- in this case sbrk cannot contiguously
++ expand the heap, but mmap may be able to map noncontiguous space.
++
++ If you'd like mmap to ALWAYS be used, you can define MORECORE to be
++ a function that always returns MORECORE_FAILURE.
++
++ If you are using this malloc with something other than sbrk (or its
++ emulation) to supply memory regions, you probably want to set
++ MORECORE_CONTIGUOUS as false. As an example, 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
++ #define MORECORE_CONTIGUOUS 0
++
++ 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 * 1024)
++ 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 *) MORECORE_FAILURE;
++ }
++ // save ptrs so they can be freed during cleanup
++ our_os_pools[next_os_pool] = ptr;
++ next_os_pool++;
++ ptr = (void *) ((((unsigned long) 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 *) MORECORE_FAILURE;
++ }
++ else
++ {
++ return sbrk_top;
++ }
++ }

++ // called as last thing before shutting down driver

++/* ------------------------------------------------------------
++History:
++
++ V2.7.0 Sun Mar 11 14:14:06 2001 Doug Lea (dl at gee)
++ * Introduce independent_comalloc and independent_calloc.
++ Thanks to Michael Pachos for motivation and help.
++ * Make optional .h file available
++ * Allow > 2GB requests on 32bit systems.
++ * new WIN32 sbrk, mmap, munmap, lock code from <Walter@GeNeSys-e.de>.
++ 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 threshold
++ * Eliminate block-local decls to simplify tracing and debugging.
++ * Support another case of realloc via move into top
++ * Fix error occurring 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.)
