In contrast to previous work, our model is easy to apply to new settings and has a simple axiomatization, which is complete in the sense that all models of it are isomorphic. In addition to various forms of indirect reference, the resulting models support powerful features such as impredicative quantification and equirecursion moreover they are compatible with the kind of powerful substructural accounting required to model (higher-order) separation logic.
Our method can be applied in a wide variety of settings and uses only simple, elementary mathematics. We give a general method to construct models containing indirect reference by presenting a "theory of indirection". Indirect reference can appear in many guises, such as heap pointers, higher-order functions, object references, and shared-memory mutexes. Our proofs are machine-checked in Coq.ĪB - Building semantic models that account for various kinds of indirect reference has traditionally been a difficult problem. indexed addressing modes may have an additional level of indirection added. In contrast to previous work, our model is easy to apply to new settings and has a simple axiomatization, which is complete in the sense that all models of it are isomorphic. The addressing modes and instructions of the MC6809 and MC6809E are upward. Indirect reference can appear in many guises, such as heap pointers, higher-order functions, object references, and shared-memory mutexes. In indirect cultures, on the other hand (Japanese, Chinese, Indians, Saudi Arabians, for example), directly communicating negative information is seen as. ‘his love of intrigue and sly indirection’ More example sentences Pronunciation indirection /ndrkn/ /ndrkn/ Origin Late 16th century from indirect, on the pattern of direction. N2 - Building semantic models that account for various kinds of indirect reference has traditionally been a difficult problem. Meaning of indirection in English: indirection noun mass noun Indirectness or lack of straightforwardness in action, speech, or progression. T1 - A theory of indirection via approximation
