- 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

- 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. (forwarded request 1068121 from eeich)

- 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.

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
- Obsolete:

- 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.
