Update. 2000-08-26 Ulrich Drepper <drepper@redhat.com> * elf/Makefile (distribute): Add unloadmod.c, reldepmod1.c, reldepmod2.c, reldepmod3.c, and reldepmod4.c. (tests): Add unload, reldep, reldep2, and reldep3. (modules-names): Add unloadmod, reldepmod1, reldepmod2, reldepmod3, and reldepmod4. Add rules to build and run unload, reldep, reldep2, and reldep3. * elf/dl-lookup.c (_dl_lookup_symbol): Add new parameter explicit. Don't create relocation dependency if it is nonzero. (_dl_lookup_symbol_skip): Remove relocation dependency stuff. This can never happen here. (_dl_lookup_versioned_symbol): Add new parameter explicit. Don't create relocation dependency if it is nonzero. (_dl_lookup_versioned_symbol_skip): Remove relocation dependency stuff. This can never happen here. * sysdeps/generic/ldsodefs.h: Change prototypes. * elf/dl-reloc.c (RESOLVE_MAP): Pass 0 in explicit parameter to _dl_lookup_up and _dl_lookup_versioned_symbol. (RESOLV): Likewise. * elf/dl-runtime.c (fixup): Likewise. (profile_fixup): Likewise. * elf/dl-libc.c (do_dlsym): Pass 1 in explicit parameter to _dl_lookup_symbol. * elf/dl-symbol.c (_dl_symbol_value): Likewise. * elf/rtld.c (dl_main): Likewise. * elf/dl-sym.c (_dl_sym): Pass 1 in explicit parameter to _dl_lookup_symbol if handle is not RTLD_DEFAULT. Always compute and pass down the caller map. (_dl_vsym): Likewise. * elf/reldep.c: New file. * elf/reldep2.c: New file. * elf/reldep3.c: New file. * elf/reldepmod1.c: New file. * elf/reldepmod2.c: New file. * elf/reldepmod3.c: New file. * elf/reldepmod4.c: New file. * elf/unload.c: New file. * elf/unloadmod.c: New file. * elf/do-lookup.h: Remove unused undef_name parameter. * elf/dl-lookup.c: Adjust callers.
