- Update to versiom 0.3.5
common:
* Loop unrolling in TRMV has been enabled again.
* A domain error in the thread workload distribution for SYRK
has been fixed.
* gmake builds will now automatically add -fPIC to the build
options if the platform requires it.
* A pthreads key leakage (and associate crash on dlclose) in
the USE_TLS codepath was fixed.
* Building of the utest cases on systems that do not provide
an implementation of complex.h was fixed.
x86_64:
* The SkylakeX code was changed to compile on OSX.
* Unwanted application of the -march=skylake-avx512 option
to the common code parts of a DYNAMIC_ARCH build was fixed.
* Improved performance of SGEMM for small workloads on Skylake X.
* Performance of SGEMM and DGEMM was improved on Haswell.
armv8:
* A configuration error that broke the CNRM2 kernel was corrected.
* Compilation of the GEMM kernels with CMAKE was fixed.
* DYNAMIC_ARCH builds are now available with CMAKE as well.
* Using CMAKE for cross-compilation to the new cpu TARGETs
introduced in 0.3.4 now works.

- Update to version 0.3.4
common:
* The new, experimental thread-local memory allocation had
inadvertently been left enabled for gmake builds in 0.3.3
despite the announcement. It is now disabled by default,
and single-threaded builds will keep using the old
allocator even if the USE_TLS option is turned on.
* OpenBLAS will now provide enough buffer space for at least
50 threads by default.
* The output of openblas_get_config() now contains the version
number.
* A serious thread safety bug in GEMV operation with small M and
large N size has been fixed.
* The code will now automatically call blas_thread_init after
a fork if needed before handling a call to
openblas_set_num_threads
* Accesses to parallelized level3 functions from multiple
callers are now serialized to avoid thread races
(unless using OpenMP).
* This should provide better performance than the
known-threadsafe (but non-default)
USE_SIMPLE_THREADED_LEVEL3 option.
* When building LAPACK with gfortran, -frecursive is now
(again) enabled by default to ensure correct behaviour.
* The OpenBLAS version cblas.h now supports both CBLAS_ORDER
and CBLAS_LAYOUT as the name of the matrix row/column order
option.
* Externally set LDFLAGS are now passed through to the final
compile/link
* steps to facilitate setting platform-specific linker flags.

- 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

reduced overhead
* Added CBLAS interfaces to the IxAMIN BLAS extension functions
* Fixed the lapack-test target
* CMAKE builds now create an OpenBLASConfig.cmake file
* ZAXPY now uses a single thread for small input sizes
* The LAPACK code was updated from Reference-LAPACK/lapack#253
power:
* Corrected CROT and ZROT behaviour with zero INC_X
armv7:
* Corrected xDOT behaviour with zero INC_X or INC_Y
x86_64:
* Retired some older targets of DYNAMIC_ARCH builds to a
new option DYNAMIC_OLDER, this affects PENRYN,DUNNINGTON,
OPTERON,OPTERON_SSE3,BOBCAT,ATOM and NANO (which will still
be supported via the slower PRESCOTT kernels when this option
is not set)
