5What is register allocation? Explain register allocation using graph coloring algorithm. Given the following live ranges, perform register allocation with 3 registers available:
Variables: a, b, c, d, e
Live ranges overlap:
– a and b overlap
– b and c overlap
– c and d overlap
– d and e overlap
– a and c don't overlap
– b and e overlap
Draw the interference graph and assign registers.
A worked answer is on its wayMeanwhile, read the Compiler Design and Construction notes for this topic.
