Homework 5 ssa

Implement the into SSA and out of SSA transformations on Bril functions. Watch out for variables that are undefined on some paths. The script “is_ssa.py can check if a program is really in SSA and the Bril interpreter bili supports phi functions so you can execute code in the midpoint of your round trip. Measure the overhead (does the final program have more instructions (static or dynamic) the original, be sure to report the overhead in your writeup.
