  dst = bitcast src as i64
• BrIf
  Conditionally transfer control to the given PC offset if cond contains a non-zero value.
• BrIfNot

• BrIfXeq32
  Branch if a == b.
• BrIfXneq32
  Branch if a != b.

  Branch if signed a <= b.
• BrIfXult32
  Branch if unsigned a < b.
• BrIfXulteq32
  Branch if unsigned a <= b.
• Call
  Transfer control to the PC at the given offset and set the lr register to the PC just after this instruction.
• Fmov
  Move between f registers.
• GetSp
  Copy the special sp stack pointer register into an x register.
• Jump
  Unconditionally transfer control to the PC at the given offset.
• Load64
  dst = load64(ptr)
• Load32S
  dst = sign_extend(load32(ptr))
• Load32SOffset8
  dst = sign_extend(load32(ptr + offset8))
• Load32U
  dst = zero_extend(load32(ptr))
• Load32UOffset8
  dst = zero_extend(load32(ptr + offset8))
• Load64Offset8
  dst = load64(ptr + offset8)
• MaterializeOpsVisitordecode
  A visitor that materializes whole Ops as it decodes the bytecode stream.
