1Summary
2-------
3This directory contains ASM implementations of the functions
4longest_match() and inflate_fast(), for 64 bits x86 (both AMD64 and Intel EM64t),
5for use with Microsoft Macro Assembler (x64) for AMD64 and Microsoft C++ 64 bits.

7gvmat64.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
10inffasx64.asm and inffas8664.c were written by Chris Anderson, by optimizing
11   original function from Mark Adler
