Changelog for libopenblas_openmp0-32bit-0.3.27-186.7.x86_64.rpm :

* Mon Jul 29 2024 Egbert Eich - 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 - no-static.patch: do not link statically

* Tue Oct 17 2023 Bernhard Wiedemann - Delete build machine cpu count
* Fri Feb 24 2023 Egbert Eich - 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 - 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 - 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 - 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 - 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

* 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.

* 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 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.

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.
