Piton: A Mechanically Verified Assembly-Level Language: 3 (Automated Reasoning Series, 3) - Hardcover
Synopsis
A subsequent fall would result in the climber hanging from the piton―if the piton stays in the rock, the slings and carabiners do not fail, the rope does not break, the partner is holding the rope taut and secure, and the climber had not climbed too high above the piton before falling.

Synopsis
This work describes the specification and proof of a compiler for a realistically complicated assembly-level language. It defines the state of the art in machine check proofs of software. Piton is a simple assembly-level programming language for a microprocessor called the FM9001 described at the machine code level. The correctness of the implementation has been proved by a mechanical theorem prover. This book is about the exact meaning of the previous paragraph. What is Piton, exactly? What is the FM9001? How is Piton implemented on the FM9001? In what sense is the implementation correct? How is its correctness expressed mathematically? How is it proved? These questions are answered here. Also discussed is the evolutionary character of software, the Piton implementation in particular, and how proof plays a continuing role in its design and improvement. Piton is a simple but non-trivial programming language.
It provides execute-only programs, recursive subroutine call and return, stack based parameter passing, local variables, global variables and arrays, a user-visible stack for intermediate results, and seven abstract data types including integers, data addresses, program addresses and subroutine names."About this title" may belong to another edition of this title.

Hardback. Condition: Good. Mountaineers use pitons to protect themselves from falls. The lead climber wears a harness to which a rope is tied. As the climber ascends, the rope is paid out by a partner on the ground. As described thus far, the climber receives no protection from the rope or the partner. However, the climber generally carries several spike-like pitons and stops when possible to drive one into a small crack or crevice in the rock face. After climbing just above the piton, the climber clips the rope to the piton, using slings and carabiners. A subsequent fall would result in the climber hanging from the piton--if the piton stays in the rock, the slings and carabiners do not fail, the rope does not break, the partner is holding the rope taut and secure, and the climber had not climbed too high above the piton before falling. The climber's safety clearly depends on all of the components of the system. But the piton is distinguished because it connects the natural to the artificial. In 1987 I designed an assembly-level language for Warren Hunt's FM8501 verified microprocessor. I wanted the language to be conveniently used as the object code produced by verified compilers. Thus, I envisioned the language as the first software link in a trusted chain from verified hardware to verified applications programs. Thinking of the hardware as the rock I named the language Piton. Seller Inventory # CIN0792339207G
