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.
