1 Summary

     2 -------

     3 This directory contains ASM implementations of the functions

     4 longest_match() and inflate_fast(), for 64 bits x86 (both AMD64 and Intel EM64t),

     5 for use with Microsoft Macro Assembler (x64) for AMD64 and Microsoft C++ 64 bits.

     6 

     7 gvmat64.asm is written by Gilles Vollant (2005), by using Brian Raiter 686/32 bits

     8    assembly optimized version from Jean-loup Gailly original longest_match function

     9 

    10 inffasx64.asm and inffas8664.c were written by Chris Anderson, by optimizing

    11    original function from Mark Adler

    21 Build instructions

    22 ------------------

    23 run bld_64.bat with Microsoft Macro Assembler (x64) for AMD64 (ml64.exe)

    24 

    25 ml64.exe is given with Visual Studio 2005, Windows 2003 server DDK

    26 

    27 You can get Windows 2003 server DDK with ml64 and cl for AMD64 from
