basics

  • loading / storing data to vectors:
    • from constant array Constructing a vector from a literal bit pattern
    • load all bytes from pointed memory ``vld1_``
    • load from interleaved memory - support up to every 4th element (usefull for RGBA / CMYK): ``vld2_`` ``vld3_`` ``vld4_``.
    • load from interleaved/random memory - possible to load one vector element (lane) from given pointer: vld1_lane_
      • random element store ret[0]=vgetq_lane_s32(o,0), ret[1]=vgetq_lane_s32(o,1) etc
    • load using lookup tables (permutation) - possible to load 8byte vector using 2nd 8 bytes vector with memory position indexes.
  • combine 8 bit values
