Instruction changes:

  • BIF (Bitwise Insert if False) - NEON vector insert, complement of the existing BIT. Operates on 64- and 128-bit vectors.
  • REV32 (vector) — byte-reverse within each 32-bit element.
  • MOVI (8-bit replicated byte immediate) - replicates an 8-bit immediate into every byte of the destination.
