Please don't quote with code blocks. Makes reading on mobile very difficult. The quote reformatted: > In the DDC technique, source code is compiled twice: once with a second (trusted) compiler (using the source code of the compiler’s parent), and then the compiler source code is compiled using the result of the first compilation. If the result is bit-for-bit identical with the untrusted executable, then the source code accurately represents the executable.
