* hash.c (DEFAULT_SIZE): Delete. Replace with:
(gas_hash_table_size): New static variable. (set_gas_hash_table_size): New function: Records a requested size for the hash tables. (get_gas_hash_table_size): New function: Return a prime number near the requested size of the hash table. (hash_new): Use get_gas_hash_table_size. * hash.h: Add a prototype for set_gas_hash_table_size. * as.c (show_usage): Add description of new switches: --hash-size and --reduce-memory-overheads. (option_values): Add OPTION_HASH_TABLE_SIZE and OPTION_REDUCE_MEMORY_OVERHEADS. (std_longpopts): Add entries for the new options. (parse_args): Handle the new options. * Makefile.am: Add a dependency of as.c on hash.h. * Makefile.in: Regenerate. * doc/as.texinfo: Document the new switches. * NEWS: Mention the new switches.
