Changelog

* 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).
* Thu Jun 13 2024 Andreas Schwab <schwab@suse.de>
  - no-static.patch: do not link statically
* Sun Jun 09 2024 Egbert Eich <eich@suse.com>
  - 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.

      on all architectures.
    * Fixed handling of the `OPENBLAS_LOOPS` variable in several
      benchmarks.

    * Improved `GEMM` performance for ZEN targets.
    arm64:
    * Added initial support for the Cortex-A76 cpu.
    * Fixed handling of `NaN` and `Inf` arguments in `ZSCAL`.
    * Fixed default compiler options for gcc (-march and -mtune).
    * Added support for the NeoverseV2 cpu in `DYNAMIC_ARCH` builds.
    * Corrected `SCSUM` kernels (erroneously duplicating `SCASUM`
      behaviour).
    * Added SVE-enabled kernels for `CSUM`/`ZSUM`.
    * Worked around an inaccuracy in the `NRM2` kernels for NeoverseN1.
    power:
    * Improved performance of `SGEMM` on POWER8/9/10.
    * Improved performance of `DGEMM` on POWER10.
    zarch:

  - Drop upstreamed patches:
    * Use-blasint-for-INTERFACE64-compatibility.patch
    * remove-spurious-loops.patch
* Fri Oct 27 2023 Stefan Brüns <stefan.bruens@rwth-aachen.de>
  - 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).
* Sun Dec 25 2022 Stefan Brüns <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 Egbert Eich <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
  - Obsolete:
    * Define-sbgemm_r-to-fix-DYNAMIC_ARCH-builds.patch
    * Remove-extraneous-and-wrong-definition-of-sbgemm_r-on-x86_64.patch
    * Do-not-include-symbols-defined-in-driver-others-parameter.c-in-DYNAMIC_BUILD.patch

    * remove-spurious-loops.patch
    * Use-blasint-for-INTERFACE64-compatibility.patch
* Wed Sep 14 2022 Egbert Eich <eich@suse.com>
  - The toolchain and 'make' in TW have been updated to handle parallel
    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 Atri Bhattacharya <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 Egbert Eich <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 Egbert Eich <eich@suse.com>

    - Handle the change from directories to soft links properly
* Wed Apr 06 2022 Egbert Eich <eich@suse.com>
  - Also build for s390x using latest gcc as requested by IBM
    (jsc#SLE-18143, bsc#1197721).
* Mon Apr 04 2022 Egbert Eich <eich@suse.com>
  - Build HPC packages with gcc-<n> <n> >= 10 on Leap/SLE.
* Wed Mar 30 2022 Egbert Eich <eich@suse.com>
  - 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.
