- - - - float
      - xmm0, xmm1
  - - - integer multiplication
    - - mov A, B => move B to A (in godbolt)
    - - sub A, B => B = A - B
    - - extends a DWORD (32-bit value) in the eax register to a QWORD (64-bit value) in the rax register
    - - load effective address
      - the contents of memory location are not loaded
      - lea (%ebx,%esi,8), %edi — the quantity EBX+8*ESI is placed in EDI.
    - - bitwise XOR
      - pxor xmm0, xmm0 => set value in the xmm0 to 0
- - - - :arrow_right:in=10 out=10
    - - :arrow_right:in=10 out=10
- - - - number of instructions executed per cycle
    - - time required to perform some action or to produce some result
  - - - 64-bit right shifts is poor
      - 64-bit left shifts and 32-bit shift are acceptance performance
