- 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)

- 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

- 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).

- Update to version 0.3.27 (boo#1225869):
General:
* Added initial (generic) support for the `CSKY` architecture.
* Capped the maximum number of threads used in `GEMM`, `GETRF`
and `POTRF` to avoid creating underutilized or idle threads.
* Sped up multithreaded `POTRF` on all platforms.
* Added extension `openblas_set_num_threads_local()` that returns
the previous thread count.
* Re-evaluated the `SGEMV` and `DGEMV` load thresholds to avoid
activating multithreading for too small workloads.
* Improved the fallback code used when the precompiled number of
threads is exceeded, and made it callable multiple times
during the lifetime of an instance.
* Added CBLAS interfaces for the BLAS extensions `?AMIN`,`?AMAX`,
`CAXPYC` and `ZAXPYC`.
* Fixed a potential buffer overflow in the interface to the
`GEMMT` kernels.
* Fixed use of incompatible pointer types in `GEMMT` and
`C`/`ZAXPBY` as flagged by GCC-14.
* Fixed unwanted case sensitivity of the character parameters in
`?TRTRS` sped up the OpenMP thread management code.
* Fixed sizing of logical variables in `INTERFACE64` builds of
the C version of LAPACK.
* Fixed inclusion of new LAPACK and LAPACKE functions from
LAPACK 3.11 in the shared library.
* Modified the error thresholds for `SGS`/`DGS` functions in
the LAPACK testsuite to suppress spurious errors.
* Added support for calling ?NRM2 with a negative increment value
on all architectures.
* Fixed handling of the `OPENBLAS_LOOPS` variable in several

- Update to version 0.3.26:
* General:
- Improved the version of openblas.pc that is created by the
CMAKE build.
- Fixed a CMAKE-specific build problem on older versions of
MacOS.
- Worked around linking problems on old versions of MacOS.
- Corrected installation location of the lapacke_mangling
header in CMAKE builds.
- Added type declarations for complex variables to the
MSVC-specific parts of the LAPACK header.
- Significantly sped up ?GESV for small problem sizes by
introducing a lower bound for multithreading.
- Imported additions and corrections from the Reference-LAPACK
project:
+ Added new LAPACK functions for truncated QR with pivoting
(Reference-LAPACK PRs 891&941).
+ Handle miscalculation of minimum work array size in corner
cases (Reference-LAPACK PR 942).
+ Fixed use of uninitialized variables in ?GEDMD and
improved inline documentation.
+ Fixed use of uninitialized variables (and consequential
failures) in ?BBCSD.
+ Added tests for the recently introduced Dynamic Mode
Decomposition functions.
+ Fixed several memory leaks in the LAPACK testsuite.
+ Fixed counting of testsuite results by the Python script.
* x86-64:

- Recreate old library scheme for existing products:
It turned out the new scheme on existing systems has
been causing package breakages.
- Do not generate baselibs.conf for HPC builds.
- Add support for gcc11 & 12.
- For SLE/Leap on x86_64 and s390x do not mix compiler versions
as this will make the gfortran ABI version inconsistent. Instead
use the stock compiler and set the list of kernels for x86_64
cores explicitly as Cooperlake requires compiler intrinsics
which are not provided by gcc 7.
- Require at least 7G of disk space for building.

- Make sure pre-existing (arch-independent) update-alternatives
are wiped before registering new ones.
Since update-alternatives has no reliable way to check if
a certain 'generic name' exists, brute-force it and ignore
any error (boo#1208248).
- Remove totally pointless - ie. never executed - %%posttrans
script.
- Restore generic link for update-alternatives. This is usually
set by the update-alternatives and it is '%ghost'ed but rpmlint
complains.
- Add rpmlintrc rules to avoid false positives from consistently
guessing the update-alternatives generic name wrong.
- Make arch dependent generic names conditional.

OBS-URL: https://build.opensuse.org/package/show/science/openblas?expand=0&rev=156
- Do not set LIBNAMESUFFIX to mark different flavors as this causes
the SONAME to be different so that different flavors of OpenBLAS
cannot serve as plugin replacements of each other (boo#1177260).
- Fix a fallout of making alternatives directory arch dependent.
- Remove unneeded links that will be created by update-alternatives.
Create remaining links %post scripts properly %ghost-ing the files.

it seems that the 32-bit compatibility packages have revealed a
conflict which was not properly detected by installcheck and actually
has made it into Leap 15.4/SLE-15-SP4 rather than caused it: The same
issue exists in the 'regular' 64-bit packages but has remained undetected
by installcheck so far. Factory hasn't suffered from this as lapack has
been fixed properly - see boo#1207358.
The possible installcheck issue has been reported in:

- Update to v0.3.21:
* general:
- Updated the included LAPACK to Reference-LAPACK release 3.10.1
- when no Fortran compiler is available, OpenBLAS builds will now automatically
- function LAPACKE_lsame is now annotated with the GCC attribute "const" to aid static analyzers
- added USE_TLS to the list of options reported by the openblas_get_config() function
- added SYMBOLPREFIX/SYMBOLSUFFIX handling for LAPACK 3.10.0 functions added in 0.3.20
- reverted OpenMP threadpool behaviour in the exec_blas call to its state before 0.3.11, that is
the threadpool will no longer grow or shrink on demand as the overhead for this is too big at least with
GNU OpenMP. The adaptive behaviour introduced in 0.3.11 can still be requested at runtime by setting
the environment variable OMP_ADAPTIVE
- worked around spurious STFSM/CTFSM errors reported by the LAPACK testsuite
* x86_64:
- fixed determination of compiler support for AVX512 and removed the 0.3.19
- workaround for building SKYLAKEX kernels on Sandybridge hardware
- fixed compilation for the SKYLAKEX target with gcc 6
- fixed compilation of the SkyLakeX small matrix GEMM kernels with LLVM or ICC
- added support for the Zhaoxin/Centaur KH40000 cpu
- fixed a potential crash in the ZSYMV kernel used for all targets except generic
* POWER:
- worked around an overflow error in the POWER6 DNRM2 kernel
- fixed compilation on PPC440
- fixed a performance regression in the level1 BLAS on POWER10
- fixed the POWER10 ZGEMM kernel
- fixed singlethreaded builds for POWER10
- fixed compilation of the POWER10 DGEMV kernel with older gcc versions
- enabled compilation of the BFLOAT16 kernels by default
- enabled the small matrix kernels by default for DYNAMIC_ARCH builds
- added a workaround for a miscompilation of the CDOT and ZDOT kernels by GCC 12

- Build PPC64LE libraries with the lastest gcc available to
take advantage of instruction sets in later CPUs used in
the CPU specific kernels (jsc#SLE-18143, bsc#1197721).
For fortran use the stock compiler to avoid compatibility
issues between different versions of libfortran.
This is relevant for Leap/SLE only. It may be dropped once
gcc < 10 is no longer supported.
- Do the same for x86_64 on SLE to make sure Cooperlake support
is built properly.
- Remove:
* Do-not-attempt-to-check-host-CPU-if-TARGET-is-set.patch
* Create-independent-kernel-Makfile-configuration-when-building-DYNAMIC_ARCH.patch
* For-DYNAMIC_ARCH-don-t-use-sbgemm_r-as-parameter.c-doesn-t-get-build.patch
Instead, add from upstream:
* Define-sbgemm_r-to-fix-DYNAMIC_ARCH-builds.patch
* Remove-extraneous-and-wrong-definition-of-sbgemm_r-on-x86_64.patch
* Fix-checks-for-AVX512-and-atomics.patch
* Revert-AVX512-capability-check-from-PR-1980-moved-to-build.patch
* Use-CC-and-full-command-line-instead-of-hard-coding-gcc-for-AVX512-checking.patch
* Utilize-compiler-AVX512-capability-info-from-c_check-when-building-getarch.patch
BLAS/LAPACK implementation (boo#1177260).
'openblas-common-devel' will provide the removed 'openblas-devel-headers'
while the arch specific 'preferred' flavor will provide the removed

(v0.3.18)
when the build-time number of preconfigured threads is exceeded
at runtime (by an external program calling BLAS functions from
a larger number of threads), OpenBLAS will now allocate an
auxiliary control structure for up to 512 additional threads
instead of aborting
added support for Loongson's LoongArch64 cpu architecture
fixed building OpenBLAS with CMAKE and -DBUILD_BFLOAT16=ON
added support for building OpenBLAS as a CMAKE subproject
