I still think a configuration option to choose between relocation formats would be useful. It could offer: - pure ELF format (8 bytes per relocation plus .dynsym) ... already there, and then to be done: - unified 32-bit format (half the size of pure ELF) - unified 16-bit delta format (a fourth of the size of pure ELF) Note these would probably be arch-specific; but maybe not.
