- 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
as well as descriptions of environment variables that affect build and runtime behavior - 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
- improved compile-time detection of SVE capability
- added cpu autodetection and initial support for Apple M4
- added support for compilation on systems running IOS
- added support for compilation on NetBSD ("evbarm" architecture)
- fixed NRM2 implementations for generic SVE targets and the Neoverse N2
- fixed compilation for SVE-capable targets with the NVIDIA compiler
x86_64:
- fixed a wrong storage size in the SBGEMV kernel for Cooper Lake
- added cpu autodetection for Intel Granite Rapids
- added cpu autodetection for AMD Ryzen 5 series
- 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
- added support for compilation with the Intel oneAPI 2025.0 compiler on Windows
power:
- fixed multithreaded SBGEMM
- fixed a CMake build problem on POWER10
- improved the performance of SGEMV
- added vectorized implementations of SBGEMV and support for forwarding 1xN SBGEMM to them
- fixed illegal instructions and potential memory overflow in SGEMM on PPCG4
- fixed handling of NaN and Inf arguments in SSCAL and DSCAL on PPC440,G4 and 970
- added improved CGEMM and ZGEMM kernels for POWER10
- added Makefile logic to remove all optimization flags in DEBUG builds
mips64:
- fixed compilation with gcc14
- fixed GEMM parameter selection for the MIPS64_GENERIC target
- fixed a potential build failure when compiling with OpenMP
loongarch64:
- fixed compilation for Loongson3 with recent versions of gmake
- fixed a potential loss of precision in Loongson3A GEMM
- fixed a potential build failure when compiling with OpenMP
- added optimized SOMATCOPY for LASX-capable targets
- introduced a new cpu naming scheme while retaining compatibility
- added support for cross-compiling Loongarch64 targets with CMake
