* Fri Jul 10 2026 Christian Goll <cgoll@suse.com>

tests to non conflicting locations
* Tue Jun 30 2026 Christian Goll <cgoll@suse.com>
- disable tests for i586 as sblat tests fail
* Fri Jun 12 2026 Christian Goll <cgoll@suse.com>
- Added compatlib packages (compatlibopenblas_serial0, compatlibopenblas_openmp0,
compatlibopenblas_pthreads0) that provide update-alternatives support for
backward compatibility (bsc#1268086) (bsc#1268086)
- Compatlib packages are automatically installed via Supplements when upgrading
from OpenBLAS >= 0.3.30 to maintain existing update-alternatives configurations
- The main library packages no longer require update-alternatives, making them
suitable for transactional systems. Users who need update-alternatives support
can explicitly install the compatlib packages
- Fixed pkgconfig and cmake symlinks to point directly to flavor-specific
directories (e.g., /usr/lib64/openblas-openmp/) instead of through
update-alternatives, ensuring consistent library resolution
- Updated README.SUSE to document the new packaging structure and compatlib usage
- Update to version 0.3.33

* fixed incorrect cast in SBGEMM test case causing spurious failures
* fixed invalid memory access in converted C CBLAS tests

- Removed Restore-the-non-vectorized-code-from-before-PR4880-for-POWER8.patch
as incorporated upstream
- Added testrun package which runs the tests separately, the package
itself is empty, but build fails if any test fails
* Wed Oct 15 2025 Andreas Schwab <schwab@suse.de>
- Reenable LTO on riscv64 as gcc has been fixed
* Fri May 30 2025 Richard Biener <rguenther@suse.com>
- For SLES16 target POWER9 instead of POWER8 which fixes the
issue with the reported sgemm testsuite fails. [bsc#1239545]
* Mon Mar 24 2025 Nicolas Morey <nicolas.morey@suse.com>
- Disable and remove support for gnu-hpc build flavours (bsc#1239982)
* Mon Mar 17 2025 Egbert Eich <eich@suse.com>
- 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.
* Fri Mar 14 2025 Egbert Eich <eich@suse.com>
- Use upstream patch for bsc#1239134 which is more friendly to the
non-affected power9 and power10 sub-architectures:

- Fixed uninitialized variables in the LAPACK tests for `?QP3RK`.
- Fixed potential bounds error in `?UNHR_COL`/`?ORHR_COL`.

1xN or Mx1 matrix to the corresponding GEMV kernel.
+ Wdded `DYNAMIC_ARCH` support (comprising `GENERIC_RISCV64` and
the two RVV 1.0 targets with vector length of 128 and 256).

special case of zero Y increment.
- Obsoleted: no-static.patch.
* Mon Jul 29 2024 Egbert Eich <eich@suse.com>
- 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).

- Propagate the correct CPU count to the pkgconfig file, see
gh#OpenMathLib/OpenBLAS#4275.
* Tue Oct 17 2023 Bernhard Wiedemann <bwiedemann@suse.com>
- Delete build machine cpu count
* Fri Feb 24 2023 Egbert Eich <eich@suse.com>
- 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.
* Tue Feb 14 2023 Egbert Eich <eich@suse.com>
- 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.
* Fri Feb 03 2023 Egbert Eich <eich@suse.com>
- 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.
* Wed Jan 25 2023 Egbert Eich <eich@suse.com>
- Make library links in the alternatives directory arch dependent.
This avoids conflicts when both 32-bit and 64-bit versions are
installed (boo#1207563).
