When reconstructing dynamic symbol table from the PT_DYNAMIC segment, compute dynamic symbol table size from hash table. For DT_HASH, the number of dynamic symbol table entries equals the number of chains. For DT_GNU_HASH/DT_MIPS_XHASH, only defined symbols with non-STB_LOCAL indings are in hash table. Since DT_GNU_HASH/DT_MIPS_XHASH place all symbols with STB_LOCAL binding before symbols with other bindings and all undefined symbols defined ones in dynamic symbol table, the highest symbol index in DT_GNU_HASH/DT_MIPS_XHASH is the highest dynamic symbol table index. Rewrite print_dynamic_symbol to dump dynamic symbol table for --dyn-syms and --syms --use-dynamic. binutils/ PR binutils/25707 * readelf.c (nbuckets): New. (nchains): Likewise. (buckets): Likewise.
