cannam@89: Summary
cannam@89: -------
cannam@89: This directory contains ASM implementations of the functions
cannam@89: longest_match() and inflate_fast(), for 64 bits x86 (both AMD64 and Intel EM64t),
cannam@89: for use with Microsoft Macro Assembler (x64) for AMD64 and Microsoft C++ 64 bits.
cannam@89: 
cannam@89: gvmat64.asm is written by Gilles Vollant (2005), by using Brian Raiter 686/32 bits
cannam@89:    assembly optimized version from Jean-loup Gailly original longest_match function
cannam@89: 
cannam@89: inffasx64.asm and inffas8664.c were written by Chris Anderson, by optimizing
cannam@89:    original function from Mark Adler

cannam@89: Use instructions
cannam@89: ----------------
cannam@89: Assemble the .asm files using MASM and put the object files into the zlib source
cannam@89: directory.  You can also get object files here:
cannam@89: 
cannam@89:      http://www.winimage.com/zLibDll/zlib124_masm_obj.zip
cannam@89: 
cannam@89: define ASMV and ASMINF in your project. Include inffas8664.c in your source tree,
cannam@89: and inffasx64.obj and gvmat64.obj as object to link.

cannam@89: Build instructions
cannam@89: ------------------
cannam@89: run bld_64.bat with Microsoft Macro Assembler (x64) for AMD64 (ml64.exe)
cannam@89: 
cannam@89: ml64.exe is given with Visual Studio 2005, Windows 2003 server DDK
cannam@89: 
cannam@89: You can get Windows 2003 server DDK with ml64 and cl for AMD64 from
