common:
* The new, experimental thread-local memory allocation had

openblas_set_num_threads
* Accesses to parallelized level3 functions from multiple
callers are now serialized to avoid thread races
(unless using OpenMP).

known-threadsafe (but non-default)
USE_SIMPLE_THREADED_LEVEL3 option.

(again) enabled by default to ensure correct behaviour.

and CBLAS_LAYOUT as the name of the matrix row/column order
option.

compile/link
* steps to facilitate setting platform-specific linker flags.
* A potential race condition during the build of LAPACK
(that would usually manifest itself as a failure to build
TESTING/MATGEN) has been fixed.
* xHEMV has been changed to stay single-threaded for small
input sizes where the overhead of multithreading exceeds
any possible gains
* CSWAP and ZSWAP have been limited to a single thread
except on ARMV8 or ThunderX hardware with sizable input.
* Linker flags for the PGI compiler have been updated
* Behaviour of AXPY with zero increments is now handled
in the C interface, correcting the result on at least
Intel Atom.

input matrix is now zeroed completely.

* CMAKE builds now support labeling of an INTERFACE64=1

(issue with typename __WAIT_STATUS)
armv8:
* DYNAMic_ARCH support is now available for 64bit ARM

use of both hardware commonalities and model-specific
compiler optimizations.
* XGENE1 has been removed as a TARGET, superseded by the
improved generic ARMV8 support.
armv7:
* Older assembly mnemonics have been converted to UAL
form to allow building with clang 7.0
-------------------------------------------------------------------
Tue Oct 9 19:00:49 UTC 2018 - Dmitry Roshchin <dmitry_r@opensuse.org>
- Update to version 0.3.3
common:
* thread memory allocation has been switched back to the method
used before version 0.3.1 due to unexpected problems caused by
the new code under some circumstances.
* LAPACK PR272 has been integrated, which fixes spurious errors
in DSYEVR and related functions caused by missing conversion
from ILAENV to ILAENV_2STAGE in several _2stage routines.
x86_64
* added AVX512 implementations of SDOT, DDOT, SAXPY, DAXPY,
DSCAL, DGEMVN and DSYMVL
* added a workaround for a cygwin issue that prevented compilation
of AVX512 code

is not set)
* Added an option DYNAMIC_LIST that (used in conjunction with
