* elf/dl-debug.c (_dl_debug_initialize): Check r->r_map for 0
rather than r->r_brk.
2006-11-08 Jakub Jelinek <jakub@redhat.com>
* elf/dl-load.c (decompose_rpath): Return bool rather than void.
If l->l_name is on inhibit_rpath list, set sps->dirs to -1 and
return false, otherwise return true.
(cache_rpath): Return decompose_rpath return value.
2006-11-07 Jakub Jelinek <jakub@redhat.com>
* include/libc-symbols.h (declare_symbol): Rename to...
(declare_symbol_alias): ... this. Add ORIGINAL argument, imply
strong_alias (ORIGINAL, SYMBOL) in asm to make sure it preceedes
.size directive.
* sysdeps/gnu/errlist-compat.awk: Adjust for declare_symbol_alias
changes.
* sysdeps/gnu/siglist.c: Likewise.
