The goal of this patch is to make isa-l testsuite pass on s390 with minimal changes to the library. The one and only reason isa-l does not work on s390 at the moment is that s390 is big-endian, and isa-l assumes little-endian at a lot of places. There are two flavors of this: loading/storing integers from/to memory, and overlapping structs. Loads/stores are already helpfully wrapped by unaligned.h header, so replace the functions there with endianness-aware variants. Solve struct member overlap by reversing their order on big-endian. Also, fix a couple of usages of uninitialized memory in the testsuite (found with MemorySanitizer). Fixes s390x part of #188.

Intel(R) Intelligent Storage Acceleration Library
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. Six different
polynomials supported.
- iscsi32, ieee32, t10dif, ecma64, iso64, jones64.
- Raid - calculate and operate on XOR and P+Q parity found in common RAID implementations.
- Compression - Fast deflate-compatible data compression.
- De-compression - Fast inflate-compatible data compression.
- igzip - A command line application like gzip, accelerated with ISA-L.
Also see:
- ISA-L for updates.
- For crypto functions see isa-l_crypto on github.
- The github wiki including a list of distros/ports offering binary packages as well as a list of language bindings.

Building ISA-L
Prerequisites
- Make: GNU 'make' or 'nmake' (Windows).
- Optional: Building with autotools requires autoconf/automake packages.
- Optional: Manual generation requires help2man package.
x86_64:
- Assembler: nasm. Version 2.15 or later suggested (other versions of nasm and yasm may build but with limited function support.
- Compiler: gcc, clang, icc or VC compiler.
aarch64:
- Assembler: gas v2.24 or later.
- Compiler: gcc v4.7 or later.
other:
- Compiler: Portable base functions are available that build with most C compilers.
Autotools
To build and install the library with autotools it is usually sufficient to run:
./autogen.sh
./configure
make
sudo make install
Makefile
To use a standard makefile run:
make -f Makefile.unx
Windows
On Windows use nmake to build dll and static lib:
nmake -f Makefile.nmake
or see details on setting up environment here.
Other make targets
Other targets include:
make check: create and run testsmake tests: create additional unit testsmake perfs: create included performance testsmake ex: build examplesmake other: build other utilities such as compression file testsmake doc: build API manual
