- 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:
- Fixed computation of CASUM on SkylakeX and newer targets in
the special case that AVX512 is not supported by the compiler

- 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/request/show/1066169
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

- 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:

* 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

Avoid compile-time CPU-detection (boo#1100677)
the docs in GotoBLAS_02QuickInstall.txt say
3. Specifying target architecture
If you need library for different architecture, you can use TARGET
option. You can find current available options in top of getarch.c.
For example, if you need library for Intel core2 architecture,
you'll find FORCE_CORE2 option in getarch.c. Therefore you can
specify TARGET=CORE2 (get rid of FORCE_) with make.
$shell> make TARGET=CORE2
This is rather unspecific, but my tests show it helps to get reproducible binaries and compilation still happens with -DDYNAMIC_ARCH -march=skylake-avx512
