35. Logical Instructions

• Format:

      and  destination, source
      or   destination, source
      xor  destination, source
      not  destination
  

• Semantics:

  • Perform the standard bitwise logical operations.

  • Result goes to the destination.

• TEST is a non-destructive AND instruction:

      test  destination, source
  

• TEST performs logical AND but the result is not stored in destination (similar to CMP instruction.)
