The following example illustrates many of the interesting features in Whiley, including the use of postconditions, loop invariants, type invariants, union types and flow typing.
22.
In this case, the loop invariant states what is known about the elements of the items examined so far namely, that none of them matches the given item.
23.
VC generators may require that the source code contains logical annotations provided by the programmer or the compiler such as pre / post-conditions and loop invariants ( a form of proof-carrying code ).
24.
Loop-invariant code motion, which involves moving code out of the loop if that does not change the effect of the program, is not directly related to loop invariants, which are properties of the loop overall.
25.
For 3 ., some tools exist to support mathematical proofs, usually based on the above-shown Floyd Hoare rule, that a given loop code in fact satisfies a given ( set of ) loop invariant ( s ).
26.
Where the loop invariant of fib is that x1 is the ( i + 2-1 ) th and x2 is the ( i + 2 ) th Fibonacci number, where i is the number of times fib has been jumped to.
27.
Description : Robert Floyd's landmark paper Assigning Meanings to Programs introduces the method of inductive assertions and describes how a program annotated with first-order assertions may be shown to satisfy a pre-and post-condition specification-the paper also introduces the concepts of loop invariant and verification condition.
28.
In this rule, in addition to maintaining the loop invariant, one also proves chain of members of " D " can have only finite length, so " t " cannot keep decreasing forever . ( For example, the usual order +; all these sets are meant in the mathematical, not in the computing sense, they are all infinite in particular .)
