builds with clang&gfortran
- worked around OPENMP builds with LLVM14's libomp hanging on
FreeBSD
- improved the Makefiles to require less option duplication on
"make install"
- imported the following changes from the upcoming release
3.12 of Reference-LAPACK: LAPACK PR 900, LAPACK PR 904,
LAPACK PR 907, LAPACK PR 909, LAPACK PR 926, LAPACK PR 927,
LAPACK PR 928 & 930
* x86-64:
- fixed compile-time autodetection of AMD Ryzen3 and Ryzen4
cpus
- fixed capability-based fallback selection for unknown cpus
in DYNAMIC_ARCH
- added AVX512 optimizations for ?ASUM on Sapphire Rapids and
Cooper Lake
* ARM64:
- fixed building on Apple with homebrew gcc
- fixed building with XCODE 15
- fixed building on A64FX and Cortex A710/X1/X2
- increased the default buffer size for recent ARM server cpus
* POWER:
- fixed building with the IBM xlf 16.1.1 compiler
- fixed building with IBM XL C
- added support for DYNAMIC_ARCH builds with clang
- fixed union declaration in the BFLOAT16 test case
- enable optimizations for the AIX assembler on POWER10
* LOONGARCH64:
- added an optimized SGEMV kernel
- added an optimized DTRSM kernel
- Minor rebase of openblas-ppc64be_up2_p8.patch to apply cleanly.
- Drop upstreamed patches:
* Use-blasint-for-INTERFACE64-compatibility.patch
* remove-spurious-loops.patch
* Fri Oct 27 2023 stefan.bruens@rwth-aachen.de
- Propagate the correct CPU count to the pkgconfig file, see
gh#OpenMathLib/OpenBLAS#4275.
* Tue Oct 17 2023 bwiedemann@suse.com
- Delete build machine cpu count
* Fri Feb 24 2023 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 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 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 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).
* Sun Dec 25 2022 stefan.bruens@rwth-aachen.de
- Fix aarch64 builds with GCC < 9 (i.e. Leap/SLE 15.x), disable
NEOVERSEN2 target. See gh#xianyi/OpenBLAS#3874.
* Wed Nov 30 2022 eich@suse.com
- 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

- 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

makes spawned by gcc (for LTO optimization) properly. Thus, remove
restrictions.
- Disable lto when linking test programs to speeds up building.
* Thu May 05 2022 badshah400@gmail.com
- Dynamically generate baselibs.conf for openblas flavors; this
will fix the unresolvables down the chain for arpack-ng 32-bit
bi-arch packages.
* Fri Apr 29 2022 eich@suse.com
- For non-HPC builds create links (bsc#1198885):
%_lib/libopenblas_<flavor>.so[.0] ->
%_lib/openblas-<flavor>/libopenblas.so[.0]
* Sat Apr 09 2022 eich@suse.com
- Fix issues in update paths from earlier versions introduced by
recent structural changes (bsc#1198264):
- Add Obsoletes for old package names
- Handle the change from directories to soft links properly
* Wed Apr 06 2022 eich@suse.com
- Also build for s390x using latest gcc as requested by IBM

- Build PPC64LE libraries with the latest 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

- Fix out of bounds read in ?llarv
LAPACK Reference: PR 625
CVE-2021-4048, bsc#1196513
- Limit parallel builds according to available memory.
Do NOT use %%_smp_mflags with top level 'make', set MAKE_NB_JOBS
instead and let the build do the work.
Also change -flto=auto to -flto=1: spawning even more parallel builds
on top of parallel build treads will wreak havok.
- Move calls to 'update-alternatives --remove' to %%postun instead
of %%preun as suggested by rpmlint.
- Since we build with DYNAMIC_ARCH, create separate config files for
the different target kernels to help debugging
Add Create-independent-kernel-Makfile-configuration-when-building-DYNAMIC_ARCH.patch
- Remove compiler feature detection when not using auto-detection.
Add Do-not-attempt-to-check-host-CPU-if-TARGET-is-set.patch
- Do not depend in variables which are not available when building
DYNAMIC_ARCH.
Add For-DYNAMIC_ARCH-don-t-use-sbgemm_r-as-parameter.c-doesn-t-get-build.patch
- Do not include symbols defined in driver/others/parameter.c in
DYNAMIC_BUILD to generate more conclusive error messages earlier.
Add Do-not-include-symbols-defined-in-driver-others-parameter.c-in-DYNAMIC_BUILD.patch
- Install lapack and blas libraries to an openblas-flavor
specific subdirectory of %%_libdir and set up the alternatives
to point to this directory. Set the system-wide BLAS/LAPACK
default directory to %%_libdir/openblas-default.
This way, the blas/lapack libraries will remain consistent
and from the same source. The user is able to override this
easily by setting the LD_LIBRARY_PATH to include the preferred
BLAS/LAPACK implementation (boo#1177260).
- Consolidate packages 'openblas-devel' and 'openblas-devel-headers'
into 'openblas-common-devel' (these are built for the serial
flavor only).
'openblas-common-devel' will provide the removed 'openblas-devel-headers'
while the arch specific 'preferred' flavor will provide the removed
'openblas-devel'.
- Fix the openblas default flavor selection:
[#] /usr/sbin/update-alternatives --config libopenblas.so.0
- Add cmake and pkgconfig files.
* Sun Feb 13 2022 eich@suse.com
- Fixed bsc#1195232 for good: found and removed offending entry.
This reintroduces part of:
Thu Jul 8 12:35:35 UTC 2021 - Dominique Leuenberger <dimstar@opensuse.org>
