This is not a direct answer to your question but just FYI... For ELF binaries, I could achieve something similar to GCC's __attribute__((constructor)) with

This is obviously a deviation from Rust's design philosophies. (Portability and what @DK calls "no code before main" principle.)

INIT can also be an Rust array. You might need to pay more attention to alignments.
