Question

What is All-C-uses/Some-P-uses coverage in dataflow analysis?

a.

A method of testing definition-clear paths from each definition to each computational use

b.

A method of testing definition-clear paths from each definition to each predicate use

c.

A method of testing each possible use of a definition

d.

A method of testing definition-clear paths from each definition to each computational use, and at least one definition-clear path to a predicate use if a definition is used only in predicates.

Answer: (a).A method of testing definition-clear paths from each definition to each computational use Explanation:In dataflow analysis, All-C-uses/Some-P-uses coverage requires definition-clear paths from each definition to each computational use, which are uses in computations or I/O statements. If a definition is used only in predicates, at least one definition-clear path to a predicate use must be exercised. This criterion ensures that all computational uses and at least one predicate use of a definition is being tested.
