general:

  • reverted unsafe TRSV/ZRSV optimizations introduced in 0.3.16
  • fixed a potential thread race in the thread buffer reallocation routines
    that were introduced in 0.3.18
  • fixed miscounting of thread pool size on Linux with OMP_PROC_BIND=TRUE
  • fixed CBLAS interfaces for CSROT/ZSROT and CROTG/ZROTG
  • made automatic library suffix for CMAKE builds with INTERFACE64 available
    to CBLAS-only builds

x86_64:

  • DYNAMIC_ARCH builds now fall back to the cpu with most similar capabilities
    when an unknown CPUID is encountered, instead of defaulting to Prescott
  • added cpu detection for Intel Alder Lake
  • added cpu detection for Intel Sapphire Rapids
  • added an optimized SBGEMM kernel for Sapphire Rapids
  • fixed DYNAMIC_ARCH builds on OSX with CMAKE
  • worked around DYNAMIC_ARCH builds made on Sandybridge failing on SkylakeX
  • fixed missing thread initialization for static builds on Windows/MSVC
  • fixed an excessive read in ZSYMV

POWER:

  • added support for POWER10 in big-endian mode
  • added support for building with CMAKE
  • added optimized SGEMM and DGEMM kernels for small matrix sizes

ARMV8:

  • added basic support and cputype detection for Fujitsu A64FX
  • added a generic ARMV8SVE target
  • added SVE-enabled SGEMM and DGEMM kernels for ARMV8SVE and A64FX
  • added optimized CGEMM and ZGEMM kernels for Cortex A53 and A55 cpus
  • fixed cpuid detection for Apple M1 and improved performance
  • improved compiler flag setting in CMAKE builds

RISCV64:

  • fixed improper initialization in CSCAL/ZSCAL for strided access patterns

MIPS:

  • added a GENERIC target for MIPS32
  • added support for cross-compiling to MIPS32 on x86_64 using CMAKE

MIPS64:

  • fixed misdetection of MSA capability
