Standard Construction and Destruction Algorithmson-SSA program into one that satisfies the SSA constraints. In general, this transformation occurs as one of the earliest phases in the middle-end of an optimizing compiler, when the program has been converted to three-address intermediate code. SSA destruction is sometimes called out-of-SSA transla

Advanced Construction Algorithms for SSA merge points phi-functions are added to ensure that every use of a variable corresponds to exactly one definition. In the rest of this chapter we will present three different approaches for inserting phi-functions at appropriate merge nodes. Recall that SSA construction falls into two phases of phi

SSA Reconstructions live range splitting by inserting copy operations or inserting spill and reload code during register allocation. Other optimizations, such as loop unrolling or jump threading, might duplicate code, thus adding additional variable definitions, and modify the control flow of the program. In this sec

Functional Representations of SSA, parameter passing, and mutually recursive function definitions. The correspondence extends from syntactic aspects to tasks such as SSA construction, data-flow analysis, and program transformations, and can be expressed in terms of multiple intermediate representation forms, all commonly found in c

Propagating Information Using SSA the first part, classical data-flow analysis is discussed by introducing the fundamentals of monotone frameworks on control-flow graphs. In the following part, the chapter introduces a simple and elegant data-flow engine that exploits SSA form. The engine relies on SSA form in order to efficiently
