Greg Tucker 45311ea249 Change common and igzip multibinary check from sse4.1 to sse4.2 
SSE optimized compression function is using crc32 instruction that is in SSE 4.2
not SSE4.1 as stated.  Fixes incorect choice on core 2 duo that is SSE 4.1 only.

================================================= Intel(R) Intelligent Storage Acceleration Library

Build Status

ISA-L is a collection of optimized low-level functions targeting storage applications. ISA-L includes:

  • Erasure codes - Fast block Reed-Solomon type erasure codes for any encode/decode matrix in GF(2^8).

  • CRC - Fast implementations of cyclic redundancy check. Three different polynomials supported.

    • iscsi, ieee, t10dif

  • Raid - calculate and operate on XOR and P+Q parity found in common RAID implementations.

  • Compression - Fast deflate-compatible data compression.

See ISA-L for updates. For crypto functions see isa-l_crypto on github.

Build Prerequisites

ISA-L requires yasm version 1.2.0 or later or nasm v2.11.01 or later. Building with autotools requires autoconf/automake packages.

Building ISA-L

Autotools

To build and install the library with autotools it is usually sufficient to run the following:

./autogen.sh
./configure
make
sudo make install

Other targets include: make check, make tests, make perfs, make ex (examples) and make other.

Windows

On Windows use nmake to build dll and static lib:

nmake -f Makefile.nmake

Other targes include: nmake check.
