1. [30pt] Given the following C program, (1) construct a control flow graph (CFG) for the program: make sure you understand the semantics of the break and continue statements. Then (2) calculate the DOM (i.e., dominator set) of each basic block. (3) Also, construct the dominator tree for the CFG. main() { int sum, i, j; 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. sum = 0; i = 1; while (i 10) break; i = i + 1; } printf ("sum is %d", sum); }
