| ==================================================================== | |||
| Version 0.3.29 | |||
| 12-Jan-2025 | |||
| general: | |||
| - fixed a potential NULL pointer dereference in multithreaded builds | |||
| - added function aliases for GEMMT using its new name GEMMTR adopted by Reference-BLAS | |||
| - fixed a build failure when building without LAPACK_DEPRECATED functions | |||
| - the minimum required CMake version for CMake-based builds was raised to 3.16.0 in order | |||
| to remove many compatibility and deprecation warnings | |||
| - added more detailed CMake rules for OpenMP builds (mainly to support recent LLVM) | |||
| - fixed the behavior of the recently added CBLAS_?GEMMT functions with row-major data | |||
| - improved thread scaling of multithreaded SBGEMV | |||
| - improved thread scaling of multithreaded TRTRI | |||
| - fixed compilation of the CBLAS testsuite with gcc14 (and no Fortran compiler) | |||
| - added support for option handling changes in flang-new from LLVM18 onwards | |||
| - added support for recent calling conventions changes in Cray and NVIDIA compilers | |||
| - added support for compilation with the NAG Fortran compiler | |||
| - fixed placement of the -fopenmp flag and libsuffix in the generated pkgconfig file | |||
| - improved the CMakeConfig file generated by the Makefile build | |||
| - fixed const-correctness of cblas_?geadd in cblas.h | |||
| - fixed a potential inaccuracy in multithreaded BLAS3 calls | |||
| - fixed empty implementations of get/set_affinity that print a warning in OpenMP builds | |||
| - fixed function signatures for TRTRS in the converted C version of LAPACK | |||
| - fixed omission of several single-precision LAPACK symbols in the shared library | |||
| - improved build instructions for the provided "pybench" benchmarks | |||
| - improved documentation, including added build instructions for WoA and HarmonyOS | |||
| - added a separate "make install_tests" target for use with cross-compilations | |||
| - integrated improvements and corrections from Reference-LAPACK: | |||
| - removed a comparison in LAPACKE ?tpmqrt that is always false (LAPACK PR 1062) | |||
| - fixed the leading dimension for B in tests for GGEV (LAPACK PR 1064) | |||
| - replaced the ?LARFT functions with a recursive implementation (LAPACK PR 1080) | |||
| arm: | |||
| - fixed build with recent versions of the NDK (missing .type declaration of symbols) | |||
| arm64: | |||
| - fixed a long-standing bug in the (generic) c/zgemm_beta kernel that could lead to | |||
| reads and writes outside the array bounds in some circumstances | |||
| - rewrote cpu autodetection to scan all cores and return the highest performing type | |||
| - improved the DGEMM performance for SVE targets and small matrix sizes | |||
| - improved dimension criteria for forwarding from GEMM to GEMV kernels | |||
| - added SVE kernels for ROT and SWAP | |||
| - improved SVE kernels for SGEMV and DGEMV on A64FX and NEOVERSEV1 | |||
| - added support for using the "small matrix" kernels with CMake as well | |||
| - fixed compilation on Windows on Arm | |||

| - added optimized SOMATCOPY_CT for AVX-capable targets | |||
| - fixed the fallback implementation of GEMM3M in GENERIC builds | |||
| - tentatively re-enabled builds with the EXPRECISION option | |||
| - worked around a miscompilation of tests with mingw32-gfortran14 | |||
