In the following grammar: $$\eqalign{ & X:: = X \oplus {Y \over Y} \cr & Y:: = Z*{Y \over Z} \cr & Z:: = id \cr} $$ Which of the...

A linker is given object modules for a set of programs that were compiled separately. What information need to be included in an object module?

Generation of intermediate code based on an abstract machine model is useful in compilers because

Consider the following expression: $x[i] = (p + r) * -s[i] + \frac{u}{w}$. The following sequence shows the list of triples representing the given exp...
