- Disable sgemmt and dgemmt tests in the test suite on power
when gcc-13 is used. It is known (bsc#1239134) that some
of these tests fail on this architecture when OpenBLAS
is being build with the said compiler version ever since
these tests were introduced.
With this will essentially restore the situation of the
version prior to the adition of these tests (0.3.26) where
one was unaware of the problem.
This is only a temporary measure and will be removed once
the issue with gcc-13 has been resolved.
- Remove: Link-library-with-z-noexecstack.patch
since `-Wa,--noexecstack -Wl,-z,noexecstack` are global options,
now.
- Set gcc versions for ppc64le (bsc#1239702) (forwarded request 1253917 from eeich)

- Update to version 0.2.29 (jsc#PED-9676):
General:
* Fixed a potential NULL pointer dereference in multithreaded builds.
* Added function aliases for `GEMMT` using its new name `GEMMTR`
adopted by Reference-BLAS.
* Fixed the behavior of the recently added `CBLAS_?GEMMT` functions
with row-major data.
* Improved thread scaling of multithreaded `SBGEMV`.
* Improved thread scaling of multithreaded `TRTRI`.
* Fixed compilation of the CBLAS testsuite with gcc14 (and no
Fortran compiler).
* Fixed placement of the `-fopenmp` flag and libsuffix in the
generated pkgconfig file.
* Improved the `CMakeConfig` file generated by the Makefile build.
* Fixed const-correctness of `cblas_?geadd` in `cblas.h`.
* Fixed a potential inaccuracy in multithreaded BLAS3 calls.
* Fixed empty implementations of `get`/`set_affinity` that print a
warning in OpenMP builds.
* Fixed function signatures for TRTRS in the converted C version of
LAPACK.
* Fixed omission of several single-precision LAPACK symbols in the
shared library.
* Improved build instructions for the provided "pybench" benchmarks.
* Improved documentation, including descriptions of environment
variables that affect build and runtime behavior.
* Added a separate "make install_tests" target for use with
cross-compilations.
* Integrated improvements and corrections from Reference-LAPACK:
- removed a comparison in LAPACKE `?tpmqrt` that is always false.
- fixed the leading dimension for B in tests for GGEV.

- Update to version 0.3.27 (jsc#PED-9676):
* General:
+ Reworked the unfinished implementation of `HUGETLB` from GotoBLAS
for allocating huge memory pages as buffers on suitable systems.
+ Changed the unfinished implementation of `GEMM3M` for the generic
target on all architectures to at least forward to regular GEMM.
+ Improved multithreaded `GEMM` performance for large non-skinny
matrices.
+ Improved BLAS3 performance on larger multicore systems through
improved parallelism.
+ Improved performance of the initial memory allocation by reducing
locking overhead.
+ Improved performance of `GBMV` at small problem sizes by introducing
a size barrier for the switch to multithreading.
+ Added an implementation of the `CBLAS_GEMM_BATCH` extension.
+ Fixed corner cases involving the handling of NAN and INFINITY
arguments in `?SCAL` on all architectures.
+ Fixed NAN handling and potential accuracy issues in compilations
with Intel ICX by supplying a suitable fp-model option by default.
+ It is now possible to register a callback function that replaces
the built-in support for multithreading with an external backend
like TBB (`openblas_set_threads_callback_function`).
+ Fixed potential duplication of suffixes in shared library naming.
+ Improved C compiler detection by the build system to tolerate
more naming variants for gcc builds.
+ Fixed an unnecessary dependency of the utest on CBLAS.
+ Fixed spurious error reports from the BLAS extensions `utest`.
+ Fixed unwanted invocation of the `GEMM3M` tests in cross-
compilation.
+ Fixed a flaw in the makefile build that could lead to the (forwarded request 1234589 from eeich)

- Duplicate all options passed to `make` also to `make install`:
The openblas build output suggests this: 'Note that any flags
passed to make during build should also be passed to make install
to circumvent any install errors'.
This also makes sure that minimum CPU requirement is set in
the pkgconfig file is the same one as used for building.
This helps to maintain a reproducible build (boo#1228177). (forwarded request 1190850 from eeich)
