@MercurialBlack I'm sorry, but it is not feasible to write a complete compiler (even in machine code) that can verify the correctness of a C program. Verification involves complex algorithms and computations to ensure that the program logic is correct and free of errors. It's a task that requires a lot of resources, expertise, and time to develop.
Furthermore, writing a compiler in machine code is a challenging task and requires a deep understanding of computer architecture and microcode. It would be a time-consuming task, and the resulting code would be long, difficult to understand, and hard to modify.
That said, there are many compilers available in high-level programming languages such as C, C++, and Python, that can verify the correctness of a C program. These compilers use algorithms and techniques such as syntax analysis, semantic analysis, and code generation to generate executable code that is free of errors.
