Coq proof assistant

Compare

  Analyzed about 15 hours ago

Coq is a formal proof management system: a proof done with Coq is mechanically checked by the machine. In particular, Coq allows: * to define functions or predicates, * to state mathematical theorems and software specifications, * to develop interactively formal proofs of these theorems, * to ... [More] check these proofs by a relatively small certification "kernel". [Less]

CompCert

Compare

  Analyzed about 16 hours ago

The CompCert project investigates the formal verification of realistic compilers usable for critical embedded software. Such verified compilers come with a mathematical, machine-checked proof that the generated executable code behaves exactly as prescribed by the semantics of the source program. By ... [More] ruling out the possibility of compiler-introduced bugs, verified compilers strengthen the guarantees that can be obtained by applying formal methods to source programs. The main result of the project is the CompCert C verified compiler, a high-assurance compiler for almost all of the C language (ISO C99), generating efficient code for the PowerPC, ARM, RISC-V and x86 processors.

Mathematical Components (Coq)

Compare

  Analyzed about 15 hours ago

Mathematical Components are libraries of formalized mathematics developed using the Coq proof assistant. This project finds its roots in the formal proof of the Four Color Theorem. It has been used for large scale formalization projects, including a formal proof of the Odd Order (Feit-Thompson) ... [More] Theorem. The libraries are written using the Ssreflect proof language, now part of the standard distribution of the Coq proof assistant. This is an open source project, licensed under the CeCILL-B free software license agreement. [Less]

Coq ELPI

Compare

  Analyzed about 7 hours ago

Coq-Elpi provides a Coq plugin that lets one define new commands and tactics in Elpi (Embeddable λProlog Interpreter). For that purpose it provides an embedding of Coq's terms into λProlog using the Higher-Order Abstract Syntax approach (HOAS). It also exports to Elpi a comprehensive set of Coq's ... [More] primitives, so that one can print a message, access the environment of theorems and data types, define a new constant, declare implicit arguments, type classes instances, and so on. For convenience it also provides a quotation and anti-quotation for Coq's syntax, so that one can write {{ nat -> lp:X }} in the middle of a λProlog program instead of the equivalent AST prod `_` (global (indt «Coq.Init.Datatypes.nat»)) X.
