* 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.
