anticipability
Anticipability is a concept from compiler theory and program analysis used to determine which values or conditions will be known at a particular point in a program. In a control‑flow graph, a value is called anticipatable at a node if, along every path from that node to the program’s exit, the value will be computed before it is used again. This information is employed in optimizations such as constant propagation, dead‑code elimination and the generation of efficient register allocation schedules.
Static analysis techniques compute anticipability through a data‑flow framework. The analysis works backwards, starting from program
In practice, anticipability information aids in the creation of better intermediate representations. For example, if a
Overall, anticipability is a foundational tool in modern compilers and static analysis frameworks, enabling more aggressive
