In this chapter, we describe the heart of the WFV algorithm: a set of analyses that determine properties of a function for a SIMD execution model.
The analyses presented in this chapter determine a variety of properties for the instructions, basic blocks, and loops of a scalar source function. The properties related to values are listed in Table 5.1, those related to blocks and loops in Table 5.2. They describe the behavior of the function in data-parallel execution.
