Changelog for libopenblas_pthreads-devel-0.3.21-3.68.x86_64.rpm :

* Sun Dec 25 2022 Stefan Brüns - 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 - 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:

* Do-not-include-symbols-defined-in-driver-others-parameter.c-in-DYNAMIC_BUILD.patch
* Utilize-compiler-AVX512-capability-info-from-c_check-when-building-getarch.patch
* Revert-AVX512-capability-check-from-PR-1980-moved-to-build.patch
* Fix-checks-for-AVX512-and-atomics.patch
* Use-CC-and-full-command-line-instead-of-hard-coding-gcc-for-AVX512-checking.patch- Updated/renamed:
* openblas-noexecstack.patch to Link-library-with-z-noexecstack.patch
* openblas-s390.patch to Handle-s390-correctly.patch- Added (see https://github.com/xianyi/OpenBLAS/issues/3738):
* remove-spurious-loops.patch
* Use-blasint-for-INTERFACE64-compatibility.patch
* Wed Sep 14 2022 Egbert Eich - 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 - 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 - For non-HPC builds create links (bsc#1198885): %_lib/libopenblas_.so[.0] -> %_lib/openblas-/libopenblas.so[.0]
* Sat Apr 09 2022 Egbert Eich - 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 Egbert Eich - Also build for s390x using latest gcc as requested by IBM (jsc#SLE-18143, bsc#1197721).
* Mon Apr 04 2022 Egbert Eich - Build HPC packages with gcc- >= 10 on Leap/SLE.
* Wed Mar 30 2022 Egbert Eich - 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

GEQRT2 improved the check for a Fortran compiler in CMAKE builds disabled building OpenBLAS\' optimized versions of LAPACK complex SPMV, SPR,SYMV,SYR with NO_LAPACK=1 fixed building of LAPACK on certain distributed filesystems with parallel gmake fixed building the shared library on MacOS with classic flang (v0.3.19) reverted unsafe TRSV/ZRSV optimizations introduced in 0.3.16 fixed a potential thread race in the thread buffer reallocation routines that were introduced in 0.3.18 fixed miscounting of thread pool size on Linux with OMP_PROC_BIND=TRUE fixed CBLAS interfaces for CSROT/ZSROT and CROTG/ZROTG made automatic library suffix for CMAKE builds with INTERFACE64 available to CBLAS-only builds (v0.3.18) when the build-time number of preconfigured threads is exceeded at runtime (by an external program calling BLAS functions from a larger number of threads), OpenBLAS will now allocate an auxiliary control structure for up to 512 additional threads instead of aborting added support for Loongson\'s LoongArch64 cpu architecture fixed building OpenBLAS with CMAKE and -DBUILD_BFLOAT16=ON added support for building OpenBLAS as a CMAKE subproject added support for building for Windows/ARM64 targets with clang improved support for building with the IBM xlf compiler imported Reference-LAPACK PR 625 (out-of-bounds access in ?LARRV) imported Reference-LAPACK PR 597 for testsuite compatibility with LLVM\'s libomp
* x86_64: fixed cross-compilation with CMAKE for CORE2 target fixed miscompilation of AVX512 code in DYNAMIC_ARCH builds added support for the \"incidental\" AVX512 hardware in Alder Lake when enabled in BIOS (v0.3.19) DYNAMIC_ARCH builds now fall back to the cpu with most similar capabilities when an unknown CPUID is encountered, instead of defaulting to Prescott added cpu detection for Intel Alder Lake added cpu detection for Intel Sapphire Rapids added an optimized SBGEMM kernel for Sapphire Rapids fixed DYNAMIC_ARCH builds on OSX with CMAKE worked around DYNAMIC_ARCH builds made on Sandybridge failing on SkylakeX fixed missing thread initialization for static builds on Windows/MSVC fixed an excessive read in ZSYMV (v0.3.18) added SkylakeX S/DGEMM kernels for small problem sizes (MNK<=1000000) added optimized SBGEMM for Intel Cooper Lake reinstated the performance patch for AVX512 SGEMV_T with a proper fix added a workaround for a gcc11 tree-vectorizer bug that caused spurious failures in the test programs for complex BLAS3 when compiling at -O3 (the default for cmake \"release\" builds) added support for runtime cpu count detection under Haiku OS worked around a long-standing miscompilation issue of the Haswell DGEMV_T kernel with gcc that could produce NaN output in some corner cases
* Power: added support for POWER10 in big-endian mode added support for building with CMAKE added optimized SGEMM and DGEMM kernels for small matrix sizes (v0.3.18) improved performance of DASUM on POWER10
* ARMV8: added SVE-enabled CGEMM and ZGEMM kernels for ARMV8SVE and A64FX added support for Neoverse N2 and V1 cpus (v0.3.19) added basic support and cputype detection for Fujitsu A64FX added a generic ARMV8SVE target added SVE-enabled SGEMM and DGEMM kernels for ARMV8SVE and A64FX added optimized CGEMM and ZGEMM kernels for Cortex A53 and A55 cpus fixed cpuid detection for Apple M1 and improved performance improved compiler flag setting in CMAKE builds (v0.3.18) fixed crashes (use of reserved register x18) on Apple M1 under OSX fixed building with gcc releases earlier than 5.1- 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.
