Consider the syntax directed definition shown below.
S → id : = E {gen (id.place = E.place;);}
E → E1 + E2 {t = newtemp ( ); gen (t = El.place + E2.place;); E.place = t}
E → id {E.place = id.place;}
Here, gen is a function that generates the output code, and newtemp is a function that returns the name of a new temporary variable on every call. Assume that ti's are the temporary variable names generated by newtemp. For the statement 'X: = Y + Z', the 3-address code sequence generated by this definition is
  • a)
    X = Y + Z
  • b)
    t1 = Y + Z; X = t1
  • c)
    t1 =Y; t2 = t1 + Z; X = t2
  • d)
    t1 = Y; t2 = Z; t3 = t1 + t2; X = t3
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Consider the syntax directed definition shown below.S → id : = E...
It must be B. The production E --> E + E is used only one time and hence only one temporary variable is generated.
