In compiler design, a live range refers to the sequence of instructions over which a particular variable holds a value that may be needed for future computations. Understanding live ranges is crucial for optimizing register allocation and minimizing memory usage during program execution.

Live Range

Compiler design is the process of creating software that translates high-level programming languages into machine code that a computer's processor can execute. It involves multiple stages including lexical analysis, syntax analysis, semantic analysis, optimization, and code generation, each critical for ensuring the correctness and efficiency of the resulting program.

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.

Register Allocation

Memory usage refers to the amount of memory a program or system consumes during its execution, impacting performance and resource availability. Efficient memory management is crucial for optimizing system performance, preventing memory leaks, and ensuring applications run smoothly without exhausting system resources.

Memory Usage

Program execution is the process by which a computer carries out the instructions of a program, transitioning from a static code to dynamic actions. It involves the interaction between the CPU, memory, and input/output systems to perform tasks as specified by the program's code.
