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. 1998-03-04 11:32 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
