+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.")
