* 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.
