Modify the grammar of Figure 15.6 to generate jump code for Boolean expressions, as described in Section 6.4.1. You should assume short-circuit evaluation (Section 6.1.5). Our GCD program did not employ subroutines. Extend the grammar of Figure 15.6 to handle procedures without parameters (feel free to adopt any reasonable conventions on the structure of the syntax tree). Be sure to generate appropriate prologue and epilogue code for each subroutine, and to save and restore any needed temporary registers.
