@ellishg Yes. I believe it may depend on the binary features. After discussing with @dreampiggy, I've concluded that the relocation aspects likely have minimal impact. Therefore, I prefer to maintain the current implementation to avoid introducing additional complexity in ELF relocations. How do you think?
