Chaitin's Algorithm is a graph-coloring algorithm used in compiler optimization for register allocation, which assigns variables to a limited number of CPU registers. It reduces the need for slower memory access by efficiently managing register usage, thereby enhancing program execution speed.

Graph-coloring algorithm

Compiler optimization refers to the process of improving the performance and efficiency of compiled code by transforming it without altering its output. It involves various techniques that reduce execution time, minimize resource usage, and enhance overall program performance while maintaining correctness.

Compiler Optimization

Register allocation is a crucial optimization process in compiler design that assigns a limited number of CPU registers to a program's variables to minimize memory access and enhance execution speed. It involves deciding which variables should reside in registers at any point in the program and managing the spilling of variables to memory when registers are insufficient.
