* elf/dl-lookup.c (dl_new_hash): New functions.cvs/fedora-glibc-20060710T2206
(_dl_lookup_symbol_x): Rename hash to old_hash and don't compute value here. Compute new-style hash value. Pass new hash value and reference to variable with the old value to do_lookup_x. (_dl_setup_hash): If DT_GNU_HASH is defined, use it and not old-style hash table. (_dl_debug_bindings): Pass new hash value and reference to variable with the old value to do_lookup_x. * elf/do-lookup.h (do_lookup_x): Accept additional parameter with new-style hash value and change old-style hash value parameter to be a reference. Reoganize functions to determine whether new-style hash table is available. Only fall back on old-style table. If old-style hash value is needed, compute it here. * elf/dynamic-link.h (elf_get_dynamic_info): Relocate DT_GNU_HASH entry. * elf/elf.h: Define SHT_GNU_HASH, DT_GNU_HASH, DT_TLSDEC_PLT, DT_TLSDEC_GOT. Adjust DT_ADDRNUM. * include/link.h (struct link_map): Add l_gnu_bitmask_idxbits, l_gnu_shift, l_gnu_bitmask, l_gnu_buckets and l_gnu_chain_zero. * Makeconfig: If linker supports --hash-style option add it to all linker command lines to build DSOs. * config.make.in: Define have-hash-style. * configure.in: Test whether linker supports --hash-style option. * elf/dl-misc.c (_dl_name_match_p): Make MAP parameter const. * sysdeps/generic/ldsodefs.h: Adjust prototype.
