- * I2C Functions similar to the standard memory functions.
- *
- * There are several parameters in many of the commands that bear further
- * explanations:
- *
- * {i2c_chip} is the I2C chip address (the first byte sent on the bus).
- *   Each I2C chip on the bus has a unique address.  On the I2C data bus,
- *   the address is the upper seven bits and the LSB is the "read/write"
- *   bit.  Note that the {i2c_chip} address specified on the command
- *   line is not shifted up: e.g. a typical EEPROM memory chip may have
- *   an I2C address of 0x50, but the data put on the bus will be 0xA0
- *   for write and 0xA1 for read.  This "non shifted" address notation
- *   matches at least half of the data sheets :-/.
- *
- * {addr} is the address (or offset) within the chip.  Small memory
- *   chips have 8 bit addresses.  Large memory chips have 16 bit
- *   addresses.  Other memory chips have 9, 10, or 11 bit addresses.
- *   Many non-memory chips have multiple registers and {addr} is used
- *   as the register index.  Some non-memory chips have only one register
- *   and therefore don't need any {addr} parameter.
- *
- *   The default {addr} parameter is one byte (.1) which works well for
- *   memories and registers with 8 bits of address space.
- *
- *   You can specify the length of the {addr} field with the optional .0,
- *   .1, or .2 modifier (similar to the .b, .w, .l modifier).  If you are
- *   manipulating a single register device which doesn't use an address
- *   field, use "0.0" for the address and the ".0" length field will
- *   suppress the address in the I2C data stream.  This also works for
- *   successive reads using the I2C auto-incrementing memory pointer.
- *
- *   If you are manipulating a large memory with 2-byte addresses, use
- *   the .2 address modifier, e.g. 210.2 addresses location 528 (decimal).
- *
- *   Then there are the unfortunate memory chips that spill the most
- *   significant 1, 2, or 3 bits of address into the chip address byte.
- *   This effectively makes one chip (logically) look like 2, 4, or
- *   8 chips.  This is handled (awkwardly) by #defining
- *   CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW and using the .1 modifier on the
- *   {addr} field (since .1 is the default, it doesn't actually have to
- *   be specified).  Examples: given a memory chip at I2C chip address
- *   0x50, the following would happen...
- *     i2c md 50 0 10   display 16 bytes starting at 0x000
- *                      On the bus: <S> A0 00 <E> <S> A1 <rd> ... <rd>
- *     i2c md 50 100 10 display 16 bytes starting at 0x100
- *                      On the bus: <S> A2 00 <E> <S> A3 <rd> ... <rd>
- *     i2c md 50 210 10 display 16 bytes starting at 0x210
- *                      On the bus: <S> A4 10 <E> <S> A5 <rd> ... <rd>
- *   This is awfully ugly.  It would be nice if someone would think up
- *   a better way of handling this.

-  A version of malloc/free/realloc written by Doug Lea and released to the
-  public domain.  Send questions/comments/complaints/performance data
-  to dl@cs.oswego.edu
-
-* VERSION 2.6.6  Sun Mar  5 19:10:03 2000  Doug Lea  (dl at gee)
-
-   Note: There may be an updated version of this malloc obtainable at
-	   ftp://g.oswego.edu/pub/misc/malloc.c
-	 Check before installing!
-
-* 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 a high-level description, see
-     http://g.oswego.edu/dl/html/malloc.html
-
-* Synopsis of public routines
-
-  (Much fuller descriptions are contained in the program documentation below.)
-
-  malloc(size_t n);
-     Return a pointer to a newly allocated chunk of at least n bytes, or null
-     if no space is available.
-  free(Void_t* p);
-     Release the chunk of memory pointed to by p, or no effect if p is null.
-  realloc(Void_t* p, size_t n);
-     Return a pointer to a chunk of size n that contains the same data
-     as does chunk p up to the minimum of (n, p's size) bytes, or null
-     if no space is available. The returned pointer may or may not be
-     the same as p. If p is null, equivalent to malloc.  Unless the
-     #define REALLOC_ZERO_BYTES_FREES below is set, realloc with a
-     size argument of zero (re)allocates a minimum-sized chunk.
-  memalign(size_t alignment, size_t n);
-     Return a pointer to a newly allocated chunk of n bytes, aligned
-     in accord with the alignment argument, which must be a power of
-     two.
-  valloc(size_t n);
-     Equivalent to memalign(pagesize, n), where pagesize is the page
-     size of the system (or as near to this as can be figured out from
-     all the includes/defines below.)
-  pvalloc(size_t n);
-     Equivalent to valloc(minimum-page-that-holds(n)), that is,
-     round up n to nearest pagesize.
-  calloc(size_t unit, size_t quantity);
-     Returns a pointer to quantity * unit bytes, with all locations
-     set to zero.
-  cfree(Void_t* p);
-     Equivalent to free(p).
-  malloc_trim(size_t pad);
-     Release all but pad bytes of freed top-most memory back
-     to the system. Return 1 if successful, else 0.
-  malloc_usable_size(Void_t* p);
-     Report the number usable allocated bytes associated with allocated
-     chunk p. This may or may not report more bytes than were requested,
-     due to alignment and minimum size constraints.
-  malloc_stats();
-     Prints brief summary statistics.
-  mallinfo()
-     Returns (by copy) a struct containing various summary statistics.
-  mallopt(int parameter_number, int parameter_value)
-     Changes one of the tunable parameters described below. Returns
-     1 if successful in changing the parameter, else 0.
-
-* Vital statistics:
-
-  Alignment:                            8-byte
-       8 byte alignment is currently hardwired into the design.  This
-       seems to suffice for all current machines and C compilers.
-
-  Assumed pointer representation:       4 or 8 bytes
-       Code for 8-byte pointers is untested by me but has worked
-       reliably by Wolfram Gloger, who contributed most of the
-       changes supporting this.
-
-  Assumed size_t  representation:       4 or 8 bytes
-       Note that size_t is allowed to be 4 bytes even if pointers are 8.
-
-  Minimum overhead per allocated chunk: 4 or 8 bytes
-       Each malloced chunk has a hidden overhead of 4 bytes 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.
-
-  Maximum allocated size: 4-byte size_t: 2^31 -  8 bytes
-			  8-byte size_t: 2^63 - 16 bytes
-
-       It is assumed that (possibly signed) size_t bit 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. To be conservative, values that would appear
-       as negative numbers are avoided.
-       Requests for sizes with a negative sign bit when the request
-       size is treaded as a long will return null.
-
-  Maximum overhead wastage per allocated chunk: normally 15 bytes
-
-       Alignnment demands, plus the minimum allocatable size restriction
-       make the normal worst-case wastage 15 bytes (i.e., up to 15
-       more bytes will be allocated than were requested in malloc), with
-       two exceptions:
-	 1. Because requests for zero bytes allocate non-zero space,
-	    the worst case wastage for a request of zero bytes is 24 bytes.
-	 2. For requests >= mmap_threshold that are serviced via
-	    mmap(), the worst case wastage is 8 bytes plus the remainder
-	    from a system page (the minimal mmap unit); typically 4096 bytes.
-
-* Limitations
-
-    Here are some features that are NOT currently supported
-
-    * No user-definable hooks for callbacks and the like.
-    * No automated mechanism for fully checking that all accesses
-      to malloced memory stay within their bounds.
-    * No support for compaction.
-
-* 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 have also reported adapting this malloc for use in
-    stand-alone embedded systems.
-
-    The implementation is in straight, hand-tuned ANSI C.  Among other
-    consequences, it uses a lot of macros.  Because of this, to be at
-    all usable, this code should be compiled using an optimizing compiler
-    (for example gcc -O2) that can simplify expressions and control
-    paths.
-
-  __STD_C                  (default: derived from C compiler defines)
-     Nonzero if using ANSI-standard C compiler, a C++ compiler, or
-     a C compiler sufficiently close to ANSI to get away with it.
-  DEBUG                    (default: NOT defined)
-     Define to enable debugging. Adds fairly extensive assertion-based
-     checking to help track down memory errors, but noticeably slows down
-     execution.
-  REALLOC_ZERO_BYTES_FREES (default: NOT defined)
-     Define this if you think that realloc(p, 0) should be equivalent
-     to free(p). Otherwise, since malloc returns a unique pointer for
-     malloc(0), so does realloc(p, 0).
-  HAVE_MEMCPY               (default: defined)
-     Define if you are not otherwise using ANSI STD C, but still
-     have memcpy and memset in your C library and want to use them.
-     Otherwise, simple internal versions are supplied.
-  USE_MEMCPY               (default: 1 if HAVE_MEMCPY is defined, 0 otherwise)
-     Define as 1 if you want the C library versions of memset and
-     memcpy called in realloc and calloc (otherwise macro versions are used).
-     At least on some platforms, the simple macro versions usually
-     outperform libc versions.
-  HAVE_MMAP                 (default: defined as 1)
-     Define to non-zero to optionally make malloc() use mmap() to
-     allocate very large blocks.
-  HAVE_MREMAP                 (default: defined as 0 unless Linux libc set)
-     Define to non-zero to optionally make realloc() use mremap() to
-     reallocate very large blocks.
-  malloc_getpagesize        (default: derived from system #includes)
-     Either a constant or routine call returning the system page size.
-  HAVE_USR_INCLUDE_MALLOC_H (default: NOT defined)
-     Optionally define if you are on a system with a /usr/include/malloc.h
-     that declares struct mallinfo. It is not at all necessary to
-     define this even if you do, but will ensure consistency.
-  INTERNAL_SIZE_T           (default: size_t)
-     Define to a 32-bit type (probably `unsigned int') if you are on a
-     64-bit machine, yet do not want or need to allow malloc requests of
-     greater than 2^31 to be handled. This saves space, especially for
-     very small chunks.
-  INTERNAL_LINUX_C_LIB      (default: NOT defined)
-     Defined only when compiled as part of Linux libc.
-     Also note that there is some odd internal name-mangling via defines
-     (for example, internally, `malloc' is named `mALLOc') needed
-     when compiling in this case. These look funny but don't otherwise
-     affect anything.
-  WIN32                     (default: undefined)
-     Define this on MS win (95, nt) platforms to compile in sbrk emulation.
-  LACKS_UNISTD_H            (default: undefined if not WIN32)
-     Define this if your system does not have a <unistd.h>.
-  LACKS_SYS_PARAM_H         (default: undefined if not WIN32)
-     Define this if your system does not have a <sys/param.h>.
-  MORECORE                  (default: sbrk)
-     The name of the routine to call to obtain more memory from the system.
-  MORECORE_FAILURE          (default: -1)
-     The value returned upon failure of MORECORE.
-  MORECORE_CLEARS           (default 1)
-     true (1) if the routine mapped to MORECORE zeroes out memory (which
-     holds for sbrk).
-  DEFAULT_TRIM_THRESHOLD
-  DEFAULT_TOP_PAD
-  DEFAULT_MMAP_THRESHOLD
-  DEFAULT_MMAP_MAX
-     Default values of tunable parameters (described in detail below)
-     controlling interaction with host system routines (sbrk, mmap, etc).
-     These values may also be changed dynamically via mallopt(). The
-     preset defaults are those that give best performance for typical
-     programs/systems.
-  USE_DL_PREFIX             (default: undefined)
-     Prefix all public routines with the string 'dl'.  Useful to
-     quickly avoid procedure declaration conflicts and linker symbol
-     conflicts with existing memory allocation routines.

-    Debugging:
-
-    Because freed chunks may be overwritten with link 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
-    enabled that will catch more memory errors. You probably won't be
-    able to make much sense of the actual assertion errors, but they
-    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

-    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.
-
-      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 default trim value is high enough to cause trimming only in
-      fairly extreme (by current memory consumption standards) cases.
-      It must be greater than page size to have any useful effect.  To
-      disable trimming completely, you can set to (unsigned long)(-1);

-    M_TOP_PAD is the amount of extra `padding' space to allocate or
-      retain whenever sbrk is called. It is used in two ways internally:
-
-      * When sbrk is called to extend the top of the arena to satisfy
-	a new malloc request, this much padding is added to the sbrk
-	request.
-
-      * When malloc_trim is called automatically from free(),
-	it is used as the `pad' argument.
-
-      In both cases, the actual amount of padding is rounded
-      so that the end of the arena is always a system page boundary.
-
-      The main reason for using padding is to avoid calling sbrk so
-      often. Having even a small pad greatly reduces the likelihood
-      that nearly every malloc request during program start-up (or
-      after trimming) will invoke sbrk, which needlessly wastes
-      time.
-
-      Automatic rounding-up to page-size units is normally sufficient
-      to avoid measurable overhead, so the default is 0.  However, in

-
-    M_MMAP_THRESHOLD is the request size threshold for using mmap()
-      to 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 benefit 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. Mapped memory can never become `locked' between
-      other chunks, as can happen with normally allocated chunks, which
-      menas that even trimming via malloc_trim would not release them.
-
-      However, it has the disadvantages that:
-
-	 1. The space cannot be reclaimed, consolidated, and then
-	    used to service later requests, as happens with normal chunks.
-	 2. It can lead to more wastage because of mmap page alignment
-	    requirements
-	 3. It causes malloc performance to be more dependent on host
-	    system memory management support routines which may vary in

-
-   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 boundries, so the mem portion
-    (which is returned to the user) is also on an even word boundary, and
-    thus 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.)
-
-    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).
-
-    The two exceptions to all this are
-
-     1. The special chunk `top', which 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 via
-	malloc_extend_top.)
-
-     2. Chunks allocated via mmap, which have the second-lowest-order
-	bit (IS_MMAPPED) set in their size fields.  Because they are
-	never merged or traversed from any other chunk, they have no
-	foot size or inuse information.
-
-    Available chunks are kept in any of several places (all declared below):
-
-    * `av': An array of chunks serving as bin headers for consolidated
-       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.  All procedures maintain the invariant that no
-       consolidated chunk physically borders another one. Chunks in
-       bins are kept in size order, with ties going to the
-       approximately least recently used chunk.
-
-       The chunks in each bin are maintained in decreasing sorted order by
-       size.  This is irrelevant 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 or 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.
-
-    * `top': The top-most available chunk (i.e., the one bordering the
-       end of available memory) is treated specially. It 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).
-
-    * `last_remainder': A bin holding only the remainder of the
-       most recently split (non-top) chunk. This bin is checked
-       before other non-fitting chunks, so as to provide better
-       locality for runs of sequentially allocated chunks.
-
-    *  Implicitly, through the host system's memory mapping tables.
-       If supported, requests greater than a threshold are usually
-       serviced via calls to mmap, and then later released via munmap.

-   Bins
-
-    The bins, `av_' are an array of pairs of pointers serving as the
-    heads of (initially empty) doubly-linked lists of chunks, laid out
-    in a way so that each pair can be treated as if it were in a
-    malloc_chunk. (This way, the fd/bk offsets for linking bin heads
-    and chunks are the same).
-
-    Bins for sizes < 512 bytes contain chunks of all the same size, spaced
-    8 bytes apart. Larger bins are approximately logarithmically
-    spaced. (See the table below.) The `av_' array is never mentioned
-    directly in the code, but instead via bin access macros.
-
-    Bin layout:
-
-    64 bins of size       8
-    32 bins of size      64
-    16 bins of size     512
-     8 bins of size    4096
-     4 bins of size   32768
-     2 bins of size  262144
-     1 bin  of size what's left
-
-    There is actually a little bit of slop in the numbers in bin_index
-    for the sake of speed. This makes no difference elsewhere.
-
-    The special chunks `top' and `last_remainder' get their own bins,
-    (this is implemented via yet more trickery with the av_ array),
-    although `top' is never properly linked to its bin since it is
-    always handled specially.

-/* Main public routines */

-/*
-  Malloc Algorthim:
-
-    The requested size is first converted into a usable form, `nb'.
-    This currently means to add 4 bytes overhead plus possibly more to
-    obtain 8-byte alignment and/or to obtain a size of at least
-    MINSIZE (currently 16 bytes), the smallest allocatable size.
-    (All fits are considered `exact' if they are within MINSIZE bytes.)
-
-    From there, the first successful of the following steps is taken:
-
-      1. The bin corresponding to the request size is scanned, and if
-	 a chunk of exactly the right size is found, it is taken.
-
-      2. The most recently remaindered chunk is used if it is big
-	 enough.  This is a form of (roving) first fit, used only in
-	 the absence of exact fits. Runs of consecutive requests use
-	 the remainder of the chunk used for the previous such request
-	 whenever possible. This limited use of a first-fit style
-	 allocation strategy tends to give contiguous chunks
-	 coextensive lifetimes, which improves locality and can reduce
-	 fragmentation in the long run.
-
-      3. Other bins are scanned in increasing size order, using a
-	 chunk big enough to fulfill the request, and splitting off
-	 any remainder.  This search is strictly by best-fit; i.e.,
-	 the smallest (with ties going to approximately the least
-	 recently used) chunk that fits is selected.
-
-      4. If large enough, the chunk bordering the end of memory
-	 (`top') is split off. (This use of `top' is in accord with
-	 the best-fit search rule.  In effect, `top' is treated as
-	 larger (and thus less well fitting) than any other available
-	 chunk since it can be extended to be as large as necessary
-	 (up to system limitations).
-
-      5. If the request size meets the mmap threshold and the
-	 system supports mmap, and there are few enough currently
-	 allocated mmapped regions, and a call to mmap succeeds,
-	 the request is allocated via direct memory mapping.
-
-      6. Otherwise, the top of memory is extended by
-	 obtaining more space from the system (normally using sbrk,
-	 but definable to anything else via the MORECORE macro).
-	 Memory is gathered from the system (in system page-sized
-	 units) in a way that allows chunks obtained across different
-	 sbrk calls to be consolidated, but does not require
-	 contiguous memory. Thus, it should be safe to intersperse
-	 mallocs with other sbrk calls.
-
-
-      All allocations are made from the the `lowest' part of any found
-      chunk. (The implementation invariant is that prev_inuse is
-      always true of any allocated chunk; i.e., that each allocated
-      chunk borders either a previously allocated and still in-use chunk,
-      or the base of its memory arena.)

-  Realloc algorithm:
-
-    Chunks that were obtained via mmap cannot be extended or shrunk
-    unless HAVE_MREMAP is defined, in which case mremap is used.
-    Otherwise, if their reallocation is for additional space, they are
-    copied.  If for less, they are just left alone.
-
-    Otherwise, if the reallocation is for additional space, and the
-    chunk can be extended, it is, else a malloc-copy-free sequence is
-    taken.  There are several different ways that a chunk could be
-    extended. All are tried:
-
-       * Extending forward into following adjacent free chunk.
-       * Shifting backwards, joining preceding adjacent space
-       * Both shifting backwards and extending forward.
-       * Extending into newly sbrked space
-
-    Unless the #define REALLOC_ZERO_BYTES_FREES is set, realloc with a
-    size argument of zero (re)allocates a minimum-sized chunk.
-
-    If the reallocation is for less space, and the new request is for
-    a `small' (<512 bytes) size, then the newly unused space is lopped
-    off and freed.
-
-    The old unix realloc convention of allowing the last-free'd chunk
-    to be used as an argument to realloc is no longer supported.
-    I don't know of any programs still relying on this feature,
-    and allowing it would also allow too many other incorrect
-    usages of realloc to be sensible.

-  A version of malloc/free/realloc written by Doug Lea and released to the
-  public domain.  Send questions/comments/complaints/performance data
-  to dl@cs.oswego.edu
-
-* VERSION 2.6.6  Sun Mar  5 19:10:03 2000  Doug Lea  (dl at gee)
-
-   Note: There may be an updated version of this malloc obtainable at
-	   ftp://g.oswego.edu/pub/misc/malloc.c
-	 Check before installing!
-
-* 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 a high-level description, see
-     http://g.oswego.edu/dl/html/malloc.html
-
-* Synopsis of public routines
-
-  (Much fuller descriptions are contained in the program documentation below.)
-
-  malloc(size_t n);
-     Return a pointer to a newly allocated chunk of at least n bytes, or null
-     if no space is available.
-  free(Void_t* p);
-     Release the chunk of memory pointed to by p, or no effect if p is null.
-  realloc(Void_t* p, size_t n);
-     Return a pointer to a chunk of size n that contains the same data
-     as does chunk p up to the minimum of (n, p's size) bytes, or null
-     if no space is available. The returned pointer may or may not be
-     the same as p. If p is null, equivalent to malloc.  Unless the
-     #define REALLOC_ZERO_BYTES_FREES below is set, realloc with a
-     size argument of zero (re)allocates a minimum-sized chunk.
-  memalign(size_t alignment, size_t n);
-     Return a pointer to a newly allocated chunk of n bytes, aligned
-     in accord with the alignment argument, which must be a power of
-     two.
-  valloc(size_t n);
-     Equivalent to memalign(pagesize, n), where pagesize is the page
-     size of the system (or as near to this as can be figured out from
-     all the includes/defines below.)
-  pvalloc(size_t n);
-     Equivalent to valloc(minimum-page-that-holds(n)), that is,
-     round up n to nearest pagesize.
-  calloc(size_t unit, size_t quantity);
-     Returns a pointer to quantity * unit bytes, with all locations
-     set to zero.
-  cfree(Void_t* p);
-     Equivalent to free(p).
-  malloc_trim(size_t pad);
-     Release all but pad bytes of freed top-most memory back
-     to the system. Return 1 if successful, else 0.
-  malloc_usable_size(Void_t* p);
-     Report the number usable allocated bytes associated with allocated
-     chunk p. This may or may not report more bytes than were requested,
-     due to alignment and minimum size constraints.
-  malloc_stats();
-     Prints brief summary statistics on stderr.
-  mallinfo()
-     Returns (by copy) a struct containing various summary statistics.
-  mallopt(int parameter_number, int parameter_value)
-     Changes one of the tunable parameters described below. Returns
-     1 if successful in changing the parameter, else 0.
-
-* Vital statistics:
-
-  Alignment:                            8-byte
-       8 byte alignment is currently hardwired into the design.  This
-       seems to suffice for all current machines and C compilers.
-
-  Assumed pointer representation:       4 or 8 bytes
-       Code for 8-byte pointers is untested by me but has worked
-       reliably by Wolfram Gloger, who contributed most of the
-       changes supporting this.
-
-  Assumed size_t  representation:       4 or 8 bytes
-       Note that size_t is allowed to be 4 bytes even if pointers are 8.
-
-  Minimum overhead per allocated chunk: 4 or 8 bytes
-       Each malloced chunk has a hidden overhead of 4 bytes 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.
-
-  Maximum allocated size: 4-byte size_t: 2^31 -  8 bytes
-			  8-byte size_t: 2^63 - 16 bytes
-
-       It is assumed that (possibly signed) size_t bit 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. To be conservative, values that would appear
-       as negative numbers are avoided.
-       Requests for sizes with a negative sign bit when the request
-       size is treaded as a long will return null.
-
-  Maximum overhead wastage per allocated chunk: normally 15 bytes
-
-       Alignnment demands, plus the minimum allocatable size restriction
-       make the normal worst-case wastage 15 bytes (i.e., up to 15
-       more bytes will be allocated than were requested in malloc), with
-       two exceptions:
-	 1. Because requests for zero bytes allocate non-zero space,
-	    the worst case wastage for a request of zero bytes is 24 bytes.
-	 2. For requests >= mmap_threshold that are serviced via
-	    mmap(), the worst case wastage is 8 bytes plus the remainder
-	    from a system page (the minimal mmap unit); typically 4096 bytes.
-
-* Limitations
-
-    Here are some features that are NOT currently supported
-
-    * No user-definable hooks for callbacks and the like.
-    * No automated mechanism for fully checking that all accesses
-      to malloced memory stay within their bounds.
-    * No support for compaction.
-
-* 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 have also reported adapting this malloc for use in
-    stand-alone embedded systems.
-
-    The implementation is in straight, hand-tuned ANSI C.  Among other
-    consequences, it uses a lot of macros.  Because of this, to be at
-    all usable, this code should be compiled using an optimizing compiler
-    (for example gcc -O2) that can simplify expressions and control
-    paths.
-
-  __STD_C                  (default: derived from C compiler defines)
-     Nonzero if using ANSI-standard C compiler, a C++ compiler, or
-     a C compiler sufficiently close to ANSI to get away with it.
-  DEBUG                    (default: NOT defined)
-     Define to enable debugging. Adds fairly extensive assertion-based
-     checking to help track down memory errors, but noticeably slows down
-     execution.
-  REALLOC_ZERO_BYTES_FREES (default: NOT defined)
-     Define this if you think that realloc(p, 0) should be equivalent
-     to free(p). Otherwise, since malloc returns a unique pointer for
-     malloc(0), so does realloc(p, 0).
-  HAVE_MEMCPY               (default: defined)
-     Define if you are not otherwise using ANSI STD C, but still
-     have memcpy and memset in your C library and want to use them.
-     Otherwise, simple internal versions are supplied.
-  USE_MEMCPY               (default: 1 if HAVE_MEMCPY is defined, 0 otherwise)
-     Define as 1 if you want the C library versions of memset and
-     memcpy called in realloc and calloc (otherwise macro versions are used).
-     At least on some platforms, the simple macro versions usually
-     outperform libc versions.
-  HAVE_MMAP                 (default: defined as 1)
-     Define to non-zero to optionally make malloc() use mmap() to
-     allocate very large blocks.
-  HAVE_MREMAP                 (default: defined as 0 unless Linux libc set)
-     Define to non-zero to optionally make realloc() use mremap() to
-     reallocate very large blocks.
-  malloc_getpagesize        (default: derived from system #includes)
-     Either a constant or routine call returning the system page size.
-  HAVE_USR_INCLUDE_MALLOC_H (default: NOT defined)
-     Optionally define if you are on a system with a /usr/include/malloc.h
-     that declares struct mallinfo. It is not at all necessary to
-     define this even if you do, but will ensure consistency.
-  INTERNAL_SIZE_T           (default: size_t)
-     Define to a 32-bit type (probably `unsigned int') if you are on a
-     64-bit machine, yet do not want or need to allow malloc requests of
-     greater than 2^31 to be handled. This saves space, especially for
-     very small chunks.
-  INTERNAL_LINUX_C_LIB      (default: NOT defined)
-     Defined only when compiled as part of Linux libc.
-     Also note that there is some odd internal name-mangling via defines
-     (for example, internally, `malloc' is named `mALLOc') needed
-     when compiling in this case. These look funny but don't otherwise
-     affect anything.
-  WIN32                     (default: undefined)
-     Define this on MS win (95, nt) platforms to compile in sbrk emulation.
-  LACKS_UNISTD_H            (default: undefined if not WIN32)
-     Define this if your system does not have a <unistd.h>.
-  LACKS_SYS_PARAM_H         (default: undefined if not WIN32)
-     Define this if your system does not have a <sys/param.h>.
-  MORECORE                  (default: sbrk)
-     The name of the routine to call to obtain more memory from the system.
-  MORECORE_FAILURE          (default: -1)
-     The value returned upon failure of MORECORE.
-  MORECORE_CLEARS           (default 1)
-     true (1) if the routine mapped to MORECORE zeroes out memory (which
-     holds for sbrk).
-  DEFAULT_TRIM_THRESHOLD
-  DEFAULT_TOP_PAD
-  DEFAULT_MMAP_THRESHOLD
-  DEFAULT_MMAP_MAX
-     Default values of tunable parameters (described in detail below)
-     controlling interaction with host system routines (sbrk, mmap, etc).
-     These values may also be changed dynamically via mallopt(). The
-     preset defaults are those that give best performance for typical
-     programs/systems.
-  USE_DL_PREFIX             (default: undefined)
-     Prefix all public routines with the string 'dl'.  Useful to
-     quickly avoid procedure declaration conflicts and linker symbol
-     conflicts with existing memory allocation routines.

-    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.
-
-      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 default trim value is high enough to cause trimming only in
-      fairly extreme (by current memory consumption standards) cases.
-      It must be greater than page size to have any useful effect.  To
-      disable trimming completely, you can set to (unsigned long)(-1);

-    M_TOP_PAD is the amount of extra `padding' space to allocate or
-      retain whenever sbrk is called. It is used in two ways internally:
-
-      * When sbrk is called to extend the top of the arena to satisfy
-	a new malloc request, this much padding is added to the sbrk
-	request.
-
-      * When malloc_trim is called automatically from free(),
-	it is used as the `pad' argument.
-
-      In both cases, the actual amount of padding is rounded
-      so that the end of the arena is always a system page boundary.
-
-      The main reason for using padding is to avoid calling sbrk so
-      often. Having even a small pad greatly reduces the likelihood
-      that nearly every malloc request during program start-up (or
-      after trimming) will invoke sbrk, which needlessly wastes
-      time.
-
-      Automatic rounding-up to page-size units is normally sufficient
-      to avoid measurable overhead, so the default is 0.  However, in

-    M_MMAP_THRESHOLD is the request size threshold for using mmap()
-      to 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 benefit 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. Mapped memory can never become `locked' between
-      other chunks, as can happen with normally allocated chunks, which
-      menas that even trimming via malloc_trim would not release them.
-
-      However, it has the disadvantages that:
-
-	 1. The space cannot be reclaimed, consolidated, and then
-	    used to service later requests, as happens with normal chunks.
-	 2. It can lead to more wastage because of mmap page alignment
-	    requirements
-	 3. It causes malloc performance to be more dependent on host
-	    system memory management support routines which may vary in
-	    implementation quality and may impose arbitrary
-	    limitations. Generally, servicing a request via normal
-	    malloc steps is faster than going through a system's mmap.
-
-      All together, these considerations should lead you to use mmap
-      only for relatively large requests.

-
-   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 boundries, so the mem portion
-    (which is returned to the user) is also on an even word boundary, and
-    thus 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.)
-
-    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).
-
-    The two exceptions to all this are
-
-     1. The special chunk `top', which 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 via
-	malloc_extend_top.)
-
-     2. Chunks allocated via mmap, which have the second-lowest-order
-	bit (IS_MMAPPED) set in their size fields.  Because they are
-	never merged or traversed from any other chunk, they have no
-	foot size or inuse information.
-
-    Available chunks are kept in any of several places (all declared below):
-
-    * `av': An array of chunks serving as bin headers for consolidated
-       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.  All procedures maintain the invariant that no
-       consolidated chunk physically borders another one. Chunks in
-       bins are kept in size order, with ties going to the
-       approximately least recently used chunk.
-
-       The chunks in each bin are maintained in decreasing sorted order by
-       size.  This is irrelevant 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 or 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.
-
-    * `top': The top-most available chunk (i.e., the one bordering the
-       end of available memory) is treated specially. It 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).
-
-    * `last_remainder': A bin holding only the remainder of the
-       most recently split (non-top) chunk. This bin is checked
-       before other non-fitting chunks, so as to provide better
-       locality for runs of sequentially allocated chunks.
-
-    *  Implicitly, through the host system's memory mapping tables.
-       If supported, requests greater than a threshold are usually
-       serviced via calls to mmap, and then later released via munmap.

-   Bins
-
-    The bins, `av_' are an array of pairs of pointers serving as the
-    heads of (initially empty) doubly-linked lists of chunks, laid out
-    in a way so that each pair can be treated as if it were in a
-    malloc_chunk. (This way, the fd/bk offsets for linking bin heads
-    and chunks are the same).
-
-    Bins for sizes < 512 bytes contain chunks of all the same size, spaced
-    8 bytes apart. Larger bins are approximately logarithmically
-    spaced. (See the table below.) The `av_' array is never mentioned
-    directly in the code, but instead via bin access macros.
-
-    Bin layout:
-
-    64 bins of size       8
-    32 bins of size      64
-    16 bins of size     512
-     8 bins of size    4096
-     4 bins of size   32768
-     2 bins of size  262144
-     1 bin  of size what's left
-
-    There is actually a little bit of slop in the numbers in bin_index
-    for the sake of speed. This makes no difference elsewhere.
-
-    The special chunks `top' and `last_remainder' get their own bins,
-    (this is implemented via yet more trickery with the av_ array),
-    although `top' is never properly linked to its bin since it is
-    always handled specially.

-  Malloc Algorthim:
-
-    The requested size is first converted into a usable form, `nb'.
-    This currently means to add 4 bytes overhead plus possibly more to
-    obtain 8-byte alignment and/or to obtain a size of at least
-    MINSIZE (currently 16 bytes), the smallest allocatable size.
-    (All fits are considered `exact' if they are within MINSIZE bytes.)
-
-    From there, the first successful of the following steps is taken:
-
-      1. The bin corresponding to the request size is scanned, and if
-	 a chunk of exactly the right size is found, it is taken.
-
-      2. The most recently remaindered chunk is used if it is big
-	 enough.  This is a form of (roving) first fit, used only in
-	 the absence of exact fits. Runs of consecutive requests use
-	 the remainder of the chunk used for the previous such request
-	 whenever possible. This limited use of a first-fit style
-	 allocation strategy tends to give contiguous chunks
-	 coextensive lifetimes, which improves locality and can reduce
-	 fragmentation in the long run.
-
-      3. Other bins are scanned in increasing size order, using a
-	 chunk big enough to fulfill the request, and splitting off
-	 any remainder.  This search is strictly by best-fit; i.e.,
-	 the smallest (with ties going to approximately the least
-	 recently used) chunk that fits is selected.
-
-      4. If large enough, the chunk bordering the end of memory
-	 (`top') is split off. (This use of `top' is in accord with
-	 the best-fit search rule.  In effect, `top' is treated as
-	 larger (and thus less well fitting) than any other available
-	 chunk since it can be extended to be as large as necessary
-	 (up to system limitations).
-
-      5. If the request size meets the mmap threshold and the
-	 system supports mmap, and there are few enough currently
-	 allocated mmapped regions, and a call to mmap succeeds,
-	 the request is allocated via direct memory mapping.
-
-      6. Otherwise, the top of memory is extended by
-	 obtaining more space from the system (normally using sbrk,
-	 but definable to anything else via the MORECORE macro).
-	 Memory is gathered from the system (in system page-sized
-	 units) in a way that allows chunks obtained across different
-	 sbrk calls to be consolidated, but does not require
-	 contiguous memory. Thus, it should be safe to intersperse
-	 mallocs with other sbrk calls.
-
-
-      All allocations are made from the the `lowest' part of any found
-      chunk. (The implementation invariant is that prev_inuse is
-      always true of any allocated chunk; i.e., that each allocated
-      chunk borders either a previously allocated and still in-use chunk,
-      or the base of its memory arena.)

-
-    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@yahoo.com>
-	 * Add 'LACKS_SYS_PARAM_H' for those systems without 'sys/param.h'
-	  (e.g. WIN32 platforms)
-	 * Cleanup up 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.)

-/*
- * sh.c -- a prototype Bourne shell grammar parser
- *      Intended to follow the original Thompson and Ritchie
- *      "small and simple is beautiful" philosophy, which
- *      incidentally is a good match to today's BusyBox.
- *
- * Copyright (C) 2000,2001  Larry Doolittle  <larry@doolittle.boa.org>
- *
- * Credits:
- *      The parser routines proper are all original material, first
- *      written Dec 2000 and Jan 2001 by Larry Doolittle.
- *      The execution engine, the builtins, and much of the underlying
- *      support has been adapted from busybox-0.49pre's lash,
- *      which is Copyright (C) 2000 by Lineo, Inc., and
- *      written by Erik Andersen <andersen@lineo.com>, <andersee@debian.org>.
- *      That, in turn, is based in part on ladsh.c, by Michael K. Johnson and
- *      Erik W. Troan, which they placed in the public domain.  I don't know
- *      how much of the Johnson/Troan code has survived the repeated rewrites.
- * Other credits:
- *      b_addchr() derived from similar w_addchar function in glibc-2.2
- *      setup_redirect(), redirect_opt_num(), and big chunks of main()
- *        and many builtins derived from contributions by Erik Andersen
- *      miscellaneous bugfixes from Matt Kraai
- *
- * There are two big (and related) architecture differences between
- * this parser and the lash parser.  One is that this version is
- * actually designed from the ground up to understand nearly all
- * of the Bourne grammar.  The second, consequential change is that
- * the parser and input reader have been turned inside out.  Now,
- * the parser is in control, and asks for input as needed.  The old
- * way had the input reader in control, and it asked for parsing to
- * take place as needed.  The new way makes it much easier to properly
- * handle the recursion implicit in the various substitutions, especially
- * across continuation lines.
- *
- * Bash grammar not implemented: (how many of these were in original sh?)
- *      $@ (those sure look like weird quoting rules)
- *      $_
- *      ! negation operator for pipes
- *      &> and >& redirection of stdout+stderr
- *      Brace Expansion
- *      Tilde Expansion
- *      fancy forms of Parameter Expansion
- *      aliases
- *      Arithmetic Expansion
- *      <(list) and >(list) Process Substitution
- *      reserved words: case, esac, select, function
- *      Here Documents ( << word )
- *      Functions
- * Major bugs:
- *      job handling woefully incomplete and buggy
- *      reserved word execution woefully incomplete and buggy
- * to-do:
- *      port selected bugfixes from post-0.49 busybox lash - done?
- *      finish implementing reserved words: for, while, until, do, done
- *      change { and } from special chars to reserved words
- *      builtins: break, continue, eval, return, set, trap, ulimit
- *      test magic exec
- *      handle children going into background
- *      clean up recognition of null pipes
- *      check setting of global_argc and global_argv
- *      control-C handling, probably with longjmp
- *      follow IFS rules more precisely, including update semantics
- *      figure out what to do with backslash-newline
- *      explain why we use signal instead of sigaction
- *      propagate syntax errors, die on resource errors?
- *      continuation lines, both explicit and implicit - done?
- *      memory leak finding and plugging - done?
- *      more testing, especially quoting rules and redirection
- *      document how quoting rules not precisely followed for variable assignments
- *      maybe change map[] to use 2-bit entries
- *      (eventually) remove all the printf's

- *  Header: remcom.c,v 1.34 91/03/09 12:29:49 glenne Exp $
- *
- *  Module name: remcom.c $
- *  Revision: 1.34 $
- *  Date: 91/03/09 12:29:49 $
- *  Contributor:     Lake Stevens Instrument Division$
- *
- *  Description:     low level support for gdb debugger. $
- *
- *  Considerations:  only works on target hardware $
- *
- *  Written by:      Glenn Engel $
- *  ModuleState:     Experimental $
- *
- *  NOTES:           See Below $
- *
- *  Modified for SPARC by Stu Grossman, Cygnus Support.
- *
- *  This code has been extensively tested on the Fujitsu SPARClite demo board.
- *
- *  To enable debugger support, two things need to happen.  One, a
- *  call to set_debug_traps() is necessary in order to allow any breakpoints
- *  or error conditions to be properly intercepted and reported to gdb.
- *  Two, a breakpoint needs to be generated to begin communication.  This
- *  is most easily accomplished by a call to breakpoint().  Breakpoint()
- *  simulates a breakpoint by executing a trap #1.
- *
- *************
- *
- *    The following gdb commands are supported:
- *
- * command          function                               Return value
- *
- *    g             return the value of the CPU registers  hex data or ENN
- *    G             set the value of the CPU registers     OK or ENN
- *    qOffsets      Get section offsets.  Reply is Text=xxx;Data=yyy;Bss=zzz
- *
- *    mAA..AA,LLLL  Read LLLL bytes at address AA..AA      hex data or ENN
- *    MAA..AA,LLLL: Write LLLL bytes at address AA.AA      OK or ENN
- *
- *    c             Resume at current address              SNN   ( signal NN)
- *    cAA..AA       Continue at address AA..AA             SNN
- *
- *    s             Step one instruction                   SNN
- *    sAA..AA       Step one instruction from AA..AA       SNN
- *
- *    k             kill
- *
- *    ?             What was the last sigval ?             SNN   (signal NN)
- *
- *    bBB..BB	    Set baud rate to BB..BB		   OK or BNN, then sets
- *							   baud rate
- *
- * All commands and responses are sent with a packet which includes a
- * checksum.  A packet consists of
- *
- * $<packet info>#<checksum>.
- *
