Connecting operational semantics with code in compilers or interpreters Few of these skills can be mastered in a single assignment. When you’ve completed the assignment, I hope you will feel confident of your knowledge of exactly the way judgment forms, inference rules, and derivations are written.

Denotational vs. Operational. Denotational semantics is similar to high-level operational semantics, except: Machine is gone Language is mathematics (lamda calculus) The difference between denotational and operational semantics: In operational semantics, the state changes are defined by coded algorithms for a virtual machine

Operational semantics

Operational semantics is a category of formal programming language semantics in which certain desired properties of a program, such as correctness, safety or security, are verified by constructing proofs from logical statements about its execution and procedures, rather than by attaching mathematical meanings to its terms (denotational semantics). Abstract. This is an in-depth study of the operational semantics of CSP and of the transition systems these are based on. We study the difference between finitely and infinitely branching transition systems, and between ordinary LTSs and ones where there may be acceptance or divergence information in additional labels on states.

3 Sep 2007 We present a simple imperative language, IMP, along with structural operational semantics in two styles: small-step and big-step. • the IMP

« Operational semantics » Patrick Cousot Jerome C. Hunsaker Visiting Professor Massachusetts Institute of Technology Department of Aeronautics and Astronautics Operational semantics, a fundamental tool in lan-guage design and veriﬁcation, provides a formal de-scription of the behaviour of programs. It is often deﬁned in terms of atomic, elementary transitions, de-scribing local behaviour. Mathematically, these trans- E. Operational Semantics of Programs • To model how our programs work, let’s look at an operational semantics: We’ll model execution as a sequence of “configurations” — snapshots of the program and memory state over time.

The skip and assignment statements complete in one step; the sequence and conditional statements require multiple steps; the iterative statement may complete in any number of steps or loop forever.

Operational Semantics I Speci es how a program is executed. I De nes an abstract machine (or abstract interpreter) that can run programs. I We can do this in two di erent ways: Small step semantics De ne one step of the abstract machine.

This mechanism allows the MB Service to continue to send OID requests to the miniport driver for processing without waiting for the current operation to complete.

Operational Semantics of Programs • To model how our programs work, let’s look at an operational semantics: We’ll model execution as a sequence of “configurations” — snapshots of the program and memory state over time. The semantics rules describe how step-by-step execution of the program changes memory. When CSE 6341 3 Operational vs. Axiomatic Operational semantics Explicitly describes the effects of program constructs on program state Shows not only whatthe program does, but also howit does it Essentially describes an interpreter Axiomatic semantics Describes properties of program state, using first-order logic Concerned with constructing proofs for such operational semantics An approach to the semantics of programming languages that uses the concept of an “abstract machine” that has a state and some primitive instructions or rules that cause the states to change. The machine is defined by specifying how the components of the state are changed by each of the instructions or rules.
