case class JSR(pc: PC, target: Int) extends Stmt[Nothing] with VariableFreeStmt with Product with Serializable
JSR/RET instructions in the bytecode are mapped to corresponding statements where the Ret instruction explicitly encodes the control flow by explicitly listing all target instructions. The target instructions implicitly encode the JSR instruction which called the subroutine.
- target
At creation time the
pc(absolute) of the target instruction in the original bytecode array; then the index of the respective quadruples instruction.

trueif the statement/expression is GUARANTEED to have no externally observable effect if it is not executed.trueif the statement/expression is GUARANTEED to have no externally observable effect if it is not executed. Sideeffect free instructions can be removed if the result of the evaluation of the expression/statement is not used. For those instructions, which may result in an exception, it has to be guaranteed that the exception is NEVER thrown. For example, a div instruction is sideeffect free if it is (statically) known that the divisor is always not equal to zero; otherwise, even if the result value is not used, the expression is not (potentially) side effect free. An array load is only side effect free if the array reference is non-null and if the index is valid.- returns
trueif the expression is GUARENTEED to have no side effect other than wasting some CPU cycles if it is not executed.

- Note
Deeply nested expressions are not supported; i.e. an expression's sub-expressions have to be Var or Const expressions. Generally, a statements expressions have to to simple expressions too - except of the Assignment statement; in the latter case the right-expression can have references to simple expressions. Hence, in case of Assignment statements the side-effect freenes is determined by the referenced expression; in all other cases the side-effect freeness is determined directly by the statement/expression.
