Summary-------This directory contains ASM implementations of the functionslongest_match() and inflate_fast(), for 64 bits x86 (both AMD64 and Intel EM64t),for use with Microsoft Macro Assembler (x64) for AMD64 and Microsoft C++ 64 bits.gvmat64.asm is written by Gilles Vollant (2005), by using Brian Raiter 686/32 bits assembly optimized version from Jean-loup Gailly original longest_match functioninffasx64.asm and inffas8664.c were written by Chris Anderson, by optimizing original function from Mark AdlerUse instructions----------------Copy these files into the zlib source directory.define ASMV and ASMINF in your project. Include inffas8664.c in your source tree,and inffasx64.obj and gvmat64.obj as object to link.Build instructions------------------run bld_64.bat with Microsoft Macro Assembler (x64) for AMD64 (ml64.exe)ml64.exe is given with Visual Studio 2005, Windows 2003 server DDKYou can get Windows 2003 server DDK with ml64 and cl for AMD64 from http://www.microsoft.com/whdc/devtools/ddk/default.mspx for low price)
