Update.
2001-08-07 Ulrich Drepper <drepper@redhat.com> * sysdeps/ia64/memusage.h (GETTIME): Define using hp-timing.h funcationality. * sysdeps/ia64/hp-timing.h (HP_TIMING_NOW): Fix comment. 2001-08-07 Jakub Jelinek <jakub@redhat.com> * malloc/memusage.c (initialized): New variable. (init): If not yet initialized, call me(). (me): Do all dlsym calls here. (malloc, realloc, calloc, free): If not yet initialized, call me(). If in the middle of initializing, return NULL or do nothing.
