Loader aside, that doesn't really answer my question. Statically and dynamically loaded stuff are slightly different, but the linker handles most of that automatically. For example, the linker scripts generated by GNU ld only differ in very minor things between different flavors, they don't use PHDRS at all, and list all the sections, regardless of the fact that position-dependent executable will never contain most of them. As far as I can tell, there is no reason why a single linker script can't cover all the cases (except loader, naturally). _______________________________________________ HelenOS-devel mailing list [email protected] http://lists.modry.cz/listinfo/helenos-devel
