Question

What is handle pruning in compiler design?

Answer 1

I don't know really

Answer 2

To understand handle pruning, you should know handle first.

handle: A handle of a string is a substring that matches with the RHS of the production whose reduction will be done to the LHS.

Handle Pruning: rightmost derivation in reverse..

Proper definition: when a handle is being replaced by the LHS of the production, it's handle pruning.
