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.
