Update.
1998-03-04 09:43  Ulrich Drepper  <drepper@cygnus.com>

	* elf/link.h (struct link_map): Add new field l_reloc_result.
	* elf/dl-reloc.c (_dl_relocate_object): Allocate array for results
	of relocation for the object to be profiled.
	* elf/dl-object.c (_dl_new_object): Initialize l_reloc_result field
	to NULL.
	* elf/rtld.c (_dl_start): Add comment that we must not allocate an
	array here.
	* elf/dl-runtime.c (profile_fixup): If l_reloc_result array already
	contains a result from a previous run use this instead of computing
	the value again.
	* elf/dl-minimal.c (malloc): Remove limit for size of allocation.
