If the issue is the iteration over the contents of the final .init_array section, this solution won't have that problem -- the loader will still execute .init_array entries in forward order (we'll be reversing them at link time). If the issue is the code layout of the ctors themselves, that sounds like something that could be fixed through code layout optimizations (e.g., gold's --section-ordering-file option). -cary
