* elf/dladdr.c: Remove #include <setjmp.h>, we don't use it. * shlib-versions: Set libdl=2. * elf/dl-deps.c (_dl_map_object_deps): Use a linked list of alloca'd elements and then scan it to fill the single malloc'd array, instead of using realloc to grow the array in the first pass. _dl_map_object may do some mallocs that break our stream of reallocs, and the minimal realloc can't handle that. * elf/dl-init.c (_dl_init_next): Take argument, link_map whose searchlist describes the piece of the DT_NEEDED graph to be initialized. * elf/link.h: Update prototype. * sysdeps/i386/dl-machine.h (RTLD_START): Pass _dl_loaded as argument to _dl_init_next. * sysdeps/m68k/dl-machine.h: Likewise. * elf/dl-deps.c (_dl_open): Pass new object as arg to _dl_init_next. * elf/link.h (struct link_map): Add `l_reserved' member, soaking up extra bits in last byte. * elf/dl-deps.c (_dl_map_object_deps): Use that for mark bit to avoid putting dup elts in search list. * elf/dlclose.c: Use MAP->l_searchlist to find deps to close. * elf/dlsym.c: Don't tweak linked list. Scope array given to _dl_lookup_symbol does the right thing. Tue Jun 4 02:25:44 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
