// Name : DoInstruction
//
// Description: Executes slic intructions that were previously
// "compiled" by slicif_add_op.
//
// Parameters : SOP op
//
// Globals : This function is so big no idea.
//
// Returns : -
//
// Remark(s) : The behaviour depends on the given SOP type
// if you define new operatiors you have of course modify
// or implement the according behaviour of that function.
//
// This function is called at slic run time.
