Linear Scan Allocation is a register allocation algorithm that assigns variables to a limited number of CPU registers in a single pass through the code, optimizing for simplicity and speed. It is particularly useful in just-in-time compilation environments where quick allocation decisions are essential for performance.

CPU registers are small, fast storage locations within a processor that hold data temporarily for quick access during instruction execution. They are critical for performance, providing the CPU with the ability to store and manipulate data without the latency of accessing main memory.

Just-in-time compilation is a runtime optimization technique that translates code into machine language just before execution, improving performance by combining the benefits of both interpretation and ahead-of-time compilation. It allows for adaptive optimization by compiling frequently executed code paths while maintaining flexibility and reducing startup times.
