Consider the following translation scheme: S FR R *E{print ( * ); R | E F + E {print ( + ); |F F (S)| id {print (id. value);} Here, id is a token that represents an integer and id value represents, the corresponding integer value. For an input 2 * 3 + 4 , this translation scheme prints.
Consider the syntax directed translation scheme (SDTS) given in the following. Assume attribute evaluation with bottom-up parsing, i.e., attributes are evaluated immediately after a reduction. E E1 * T {E.val = E1 .val * T. val} E T {E.val = T. val} T F T1 {T.val = F.val T1. val} T F {T.val = F. val} F 2 {F.val = 2} F 4 {F.val = 4} (a) Using this SDTS, construct a parse tree for the expression 4 2 4 * 2 and also compute its E.val. (b) It is required to compute the total number of reductions performed to parse a given input. Using synthesized attributes only, modify the SDTS given, without changing the grammar, to find E.red, the number of reductions performed while reducing an input to E.

In a simplified computer, the instructions are OP Rj, Ri Performs Rj OP Ri and stores the result in register Ri . OP m, Rj Performs val OP Ri and stores the result in Rj. val denotes the content of memory location m. MOV m, Ri Moves the content of memory location m to register Ri. MOV, Ri, m Moves the content of the register Ri to memory location m. The computer has only two registers, and OP is either ADD or SUB. Consider the following basic block: t1 = a + b t2 = c + d t3 = e t2 t4 = t1 t3Assume that all operands are initially in memory. The final value of the computation should be in memory. What is the minimum number of MOV instructions in the code generated for this basic block?
