-This is a patched version of zlib modified to use
-Pentium-optimized assembly code in the deflation algorithm. The files
-changed/added by this patch are:
-
-README.586
-match.S
-
-The effectiveness of these modifications is a bit marginal, as the the
-program's bottleneck seems to be mostly L1-cache contention, for which
-there is no real way to work around without rewriting the basic
-algorithm. The speedup on average is around 5-10% (which is generally
-less than the amount of variance between subsequent executions).
-However, when used at level 9 compression, the cache contention can
-drop enough for the assembly version to achieve 10-20% speedup (and
-sometimes more, depending on the amount of overall redundancy in the
-files). Even here, though, cache contention can still be the limiting
-factor, depending on the nature of the program using the zlib library.
-This may also mean that better improvements will be seen on a Pentium
-with MMX, which suffers much less from L1-cache contention, but I have
-not yet verified this.
-
-Note that this code has been tailored for the Pentium in particular,
-and will not perform well on the Pentium Pro (due to the use of a
-partial register in the inner loop).
-
-If you are using an assembler other than GNU as, you will have to
-translate match.S to use your assembler's syntax. (Have fun.)

- * Two optimization notes on the choice of instructions:

- * The first instruction uses a 16-bit address, which costs an extra,
- * unpairable cycle. This is cheaper than doing a 32-bit access and
- * zeroing the high word, due to the 3-cycle misalignment penalty which
- * would occur half the time. This also turns out to be cheaper than
- * doing two separate 8-bit accesses, as the memory is so rarely in the
- * L1 cache.
- *
- * The window buffer, however, apparently spends a lot of time in the
- * cache, and so it is faster to retrieve the word at the end of the
- * match string with two 8-bit loads. The instructions that test the
- * word at the beginning of the match string, however, are executed
- * much less frequently, and there it was cheaper to use 16-bit
- * instructions, which avoided the necessity of saving off and
- * subsequently reloading one of the other registers.

-;  longest_match_686 : written by Brian raiter (1998), optimized for Pentium Pro

-;

-;  for using an seembly version of longest_match, you need define ASMV in project

-;  A) Suggested method

-;    if you want include both longest_match_7fff and longest_match_686

-;    compile the asm file running

-;           ml /coff /Zi /Flgvmat32.lst /c gvmat32.asm

-;    if you have an old cpu (386,486 or first Pentium) and s->w_mask==0x7fff,

-;        longest_match_7fff will be used

-;    if you have a more modern CPU (Pentium Pro, II and higher)

-;        longest_match_686 will be used

-;    on old cpu with s->w_mask!=0x7fff, longest_match_686 will be used,

-;        but this is not a sitation you'll find often

-;

-;  B) Alternative

-;    if you are not interresed in old cpu performance and want the smaller

-;       binaries possible

-;

-;    compile the asm file running

-;           ml /coff /Zi /c /Flgvmat32.lst /DNOOLDPENTIUMCODE gvmat32.asm

-;    and do not include gvmat32c.c in your project (ou define also 

-;              NOOLDPENTIUMCODE)

-;

-; note : as I known, longest_match_686 is very faster than longest_match_7fff

-;        on pentium Pro/II/III, faster (but less) in P4, but it seem

-;        longest_match_7fff can be faster (very very litte) on AMD Athlon64/K8

-This project builds the zlib binaries as follows:

-

-* Win32_DLL_Release\zlib1.dll       DLL build

-* Win32_DLL_Debug\zlib1d.dll        DLL build (debug version)

-* Win32_DLL_ASM_Release\zlib1.dll   DLL build using ASM code

-* Win32_DLL_ASM_Debug\zlib1d.dll    DLL build using ASM code (debug version)

-* Win32_LIB_Release\zlib.lib        static build

-* Win32_LIB_Debug\zlibd.lib         static build (debug version)

-* Win32_LIB_ASM_Release\zlib.lib    static build using ASM code

-* Win32_LIB_ASM_Debug\zlibd.lib     static build using ASM code (debug version)

-

-

-For more information regarding the DLL builds, please see the DLL FAQ

-in ..\..\win32\DLL_FAQ.txt.

-

-

-To build and test:

-

-1) On the main menu, select "File | Open Workspace".

-   Open "zlib.dsw".

-

-2) Select "Build | Set Active Configuration".

-   Choose the configuration you wish to build.

-

-3) Select "Build | Clean".

-

-4) Select "Build | Build ... (F7)".  Ignore warning messages about

-   not being able to find certain include files (e.g. alloc.h).

-

-5) If you built one of the sample programs (example or minigzip),

-   select "Build | Execute ... (Ctrl+F5)".

-

-

-To use:

-

-1) Select "Project | Settings (Alt+F7)".

-   Make note of the configuration names used in your project.

-   Usually, these names are "Win32 Release" and "Win32 Debug".

-

-2) In the Workspace window, select the "FileView" tab.

-   Right-click on the root item "Workspace '...'".

-   Select "Insert Project into Workspace".

-   Switch on the checkbox "Dependency of:", and select the name

-   of your project.  Open "zlib.dsp".

-

-3) Select "Build | Configurations".

-   For each configuration of your project:

-   3.1) Choose the zlib configuration you wish to use.

-   3.2) Click on "Add".

-   3.3) Set the new zlib configuration name to the name used by

-        the configuration from the current iteration.

-

-4) Select "Build | Set Active Configuration".

-   Choose the configuration you wish to build.

-

-5) Select "Build | Build ... (F7)".

-

-6) If you built an executable program, select

-   "Build | Execute ... (Ctrl+F5)".

-

-

-Note:

-

-To build the ASM-enabled code, you need Microsoft Assembler

-(ML.EXE).  You can get it by downloading and installing the

-latest Processor Pack for Visual C++ 6.0.

+/*
+   These memory tracking routines are provided to zlib and track all of zlib's
+   allocations and deallocations, check for LIFO operations, keep a current
+   and high water mark of total bytes requested, optionally set a limit on the
+   total memory that can be allocated, and when done check for memory leaks.
+
+   They are used as follows:
+
+   z_stream strm;
+   mem_setup(&strm)         initializes the memory tracking and sets the
+                            zalloc, zfree, and opaque members of strm to use
+                            memory tracking for all zlib operations on strm
+   mem_limit(&strm, limit)  sets a limit on the total bytes requested -- a
+                            request that exceeds this limit will result in an
+                            allocation failure (returns NULL) -- setting the
+                            limit to zero means no limit, which is the default
+                            after mem_setup()
+   mem_used(&strm, "msg")   prints to stderr "msg" and the total bytes used
+   mem_high(&strm, "msg")   prints to stderr "msg" and the high water mark
+   mem_done(&strm, "msg")   ends memory tracking, releases all allocations
+                            for the tracking as well as leaked zlib blocks, if
+                            any.  If there was anything unusual, such as leaked
+                            blocks, non-FIFO frees, or frees of addresses not
+                            allocated, then "msg" and information about the
+                            problem is printed to stderr.  If everything is
+                            normal, nothing is printed. mem_done resets the
+                            strm members to Z_NULL to use the default memory
+                            allocation routines on the next zlib initialization
+                            using strm.
