Drop upstreamed patches: * Use-blasint-for-INTERFACE64-compatibility.patch * remove-spurious-loops.patch ------------------------------------------------------------------- Fri Oct 27 11:26:28 UTC 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 02:18:53 UTC 2023 - Bernhard Wiedemann <bwiedemann@suse.com> - Delete build machine cpu count ------------------------------------------------------------------- Fri Feb 24 09:57:34 UTC 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 18:14:06 UTC 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 3 07:52:04 UTC 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 21:13:49 UTC 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 00:19:21 UTC 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 19:24:20 UTC 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 - 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: * 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 * 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 06:08:40 UTC 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 5 11:56:20 UTC 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 16:36:57 UTC 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 9 06:13:09 UTC 2022 - Egbert Eich <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 6 06:57:55 UTC 2022 - Egbert Eich <eich@suse.com> - Also build for s390x using latest gcc as requested by IBM (jsc#SLE-18143, bsc#1197721). ------------------------------------------------------------------- Mon Apr 4 08:57:16 UTC 2022 - Egbert Eich <eich@suse.com> - Build HPC packages with gcc-<n> <n> >= 10 on Leap/SLE. ------------------------------------------------------------------- Wed Mar 30 12:00:30 UTC 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 * For-DYNAMIC_ARCH-don-t-use-sbgemm_r-as-parameter.c-doesn-t-get-build.patch Instead, add from upstream: * Define-sbgemm_r-to-fix-DYNAMIC_ARCH-builds.patch * Remove-extraneous-and-wrong-definition-of-sbgemm_r-on-x86_64.patch * Fix-checks-for-AVX512-and-atomics.patch * Revert-AVX512-capability-check-from-PR-1980-moved-to-build.patch * Use-CC-and-full-command-line-instead-of-hard-coding-gcc-for-AVX512-checking.patch * Utilize-compiler-AVX512-capability-info-from-c_check-when-building-getarch.patch ------------------------------------------------------------------- Fri Feb 25 20:10:04 UTC 2022 - Egbert Eich <eich@suse.com> - Update to v0.3.20: * general: some code cleanup, with added casts etc. fixed obtaining the cpu count with OpenMP and OMP_PROC_BIND unset fixed pivot index calculation by ?LASWP for negative increments other than one fixed input argument check in LAPACK ?

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-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 16:02:01 UTC 2022 - Egbert Eich <eich@suse.com> - Fixed bsc#1195232 for good: found and removed offending entry.
