Here are some rules the program should follow: ./a.out must run successfully. $? must deterministically be 0. The binary must be produced by GCC only; no post-processing with objcopy, hex editors, or manual patching. We begin with the simplest program possible: // compiled with gcc empty.c int main() { return 0; } This gives us a file size of 15816 bytes (from stat). https://blog.weineng.me/about/ Sun, 29 Oct 2023 20:00:00 -0400 https://blog.weineng.me/about/ Hi, I’m Weineng.
