    (synopsis "Certified C compiler")
    (description "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 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.")
