Webcommon compilers used in garbled circuit research. We deﬁne the correctness of a complier implementation using two criteria: (1) any valid program in the language can be successfully compiled, and (2) the compiler creates the correct output program based on the input ﬁle. There are two methods used to demonstrate compiler correctness: formal Webof bugs in compilers silently turning a correct program into an in-correct executable. For low-assurance software, validated only by testing, the im-pact of compiler bugs is negligible: what is tested is the executable code produced by the compiler; rigorous testing will expose errors in the compiler along with errors in the source program. The ...
