New Power 10 MMA Backend

  • Initial support for Power 10 matrix multiplication assist instructions for float32, float64 real and complex.

Altivec/Power improvements

  • General performance improvement and bugfixes.
  • Enhanced vectorization of current real and complex scalars.
  • Changes to the gebp_kernel specific to Altivec, using VSX implementation of the MMA instructions that gain speed improvements up to 4x for matrix-matrix products.
  • Dynamic dispatch for GCC greater than 10 enabling selection of MMA or VSX instructions based on __builtin_cpu_supports.
