synopsis: "Verified Software Toolchain"
description: "The software toolchain includes static analyzers to check assertions about your program; optimizing compilers to translate your program to machine language; operating systems and libraries to supply context for your program. The Verified Software Toolchain project assures with machine-checked proofs that the assertions claimed at the top of the toolchain really hold in the machine-language program, running in the operating-system context."
