In the discussion on related feature in AArch64 backend (, there were decisions taken:

  • rename "rdma" subtarget feature to "v8_1a"
  • not to introduce intrinsics, instead perform fusion "x = sqrdmlah(x.y.z) --> x = sqadd(x, sqrdmulh(y.z)"

This way, this revision is invalid, I will upload next one soon.
