------------------------------------------------------------------------------
  [[BR]][[BR]]  {{{5)}}}  If the operand (referred as original operand here) is live at entry of a catch handler then necessary operand splitting is performed as close as possible to the instruction which caused the splitting and original operand is used before and after the instruction. 
  [[BR]]The main principle of the algorithm is anding of instruction constraints into operand calculated constraints and splitting operands to ensure that the calculated constraint is not null
  [[BR]]This transformer must be inserted before register allocator which relies on calculated operand constraints.
