added initial (generic) support for the CSKY architecture
capped the maximum number of threads used in GEMM, GETRF and POTRF to avoid creating
underutilized or idle threads
sped up multithreaded POTRF on all platforms
added extension openblas_set_num_threads_local() that returns the previous thread count
re-evaluated the SGEMV and DGEMV load thresholds to avoid activating multithreading
for too small workloads
improved the fallback code used when the precompiled number of threads is exceeded,
and made it callable multiple times during the lifetime of an instance
added CBLAS interfaces for the BLAS extensions ?AMIN,?AMAX, CAXPYC and ZAXPYC
fixed a potential buffer overflow in the interface to the GEMMT kernels
fixed use of incompatible pointer types in GEMMT and C/ZAXPBY as flagged by GCC-14
fixed unwanted case sensitivity of the character parameters in ?TRTRS
sped up the OpenMP thread management code
fixed sizing of logical variables in INTERFACE64 builds of the C version of LAPACK
fixed inclusion of new LAPACK and LAPACKE functions from LAPACK 3.11 in the shared library
added a testsuite for the BLAS extensions
modified the error thresholds for SGS/DGS functions in the LAPACK testsuite to suppress
spurious errors
added support for building the benchmark collection with CMAKE
added rewriting of linker options to avoid linking both libgomp and libomp in CMAKE builds
with OpenMP enabled that use clang with gfortran
fixed building on systems with ucLibc
added support for calling ?NRM2 with a negative increment value on all architectures
added support for the LLVM18 version of the flang-new compiler
fixed handling of the OPENBLAS_LOOPS variable in several benchmarks
