CYGWIN CHANGES
rebuilt with debuginfo enabled

CHANGES
New upstream release
http://www.openblas.net/Changelog.txt

* Various bux fixes and optimizations
* Support Intel Boardwell and Skylake by Haswell kernels.
* Support AMD Excavator by Steamroller kernels.

DESCRIPTION
OpenBLAS is an optimized BLAS library based on GotoBLAS2 1.13
BSD version and further extended.
OpenBLAS is licensed under the 3-clause BSD license.

HOMEPAGE
http://www.openblas.net/

CYGWIN NOTES
1) As BLAS it is around 5-10 times faster than Netlib reference,
    included in the liblapack0 package.

2) No devel package is provided as liblapack-devel already provide
    the needed headers and import.
    Openblas is fully compatible with Netlib BLAS.

3) libopenblas consist of a single file
      /usr/bin/cygblas-0.dll
    that will precede in PATH the liblapack0
      /usr/lib/lapack/cygblas-0.dll
    and used instead. Removing libopenblas will restore the
    usage of Netlib BLAS

4) CPU architecture covered up to now

     ATHLON ATOM BANIAS BARCELONA BOBCAT COPPERMINE CORE2
     DUNNINGTON KATMAI NANO NEHALEM NORTHWOOD OPTERON
     OPTERON_SSE3 PENRYN PRESCOTT

5) Built with a max number of 16 threads; it should be enough
    to fully utilize up a 8 core dual thread.
    The fixed max limit at build time is a upstream limitation,
    if you need more than 16 let me know.
