(msymbol_hash_iw): Likewise.
(add_minsym_to_hash_table): Take modulus of msymbol_hash's return
value.
(add_minsym_to_demangled_hash_table): Likewise for msymbol_hash_iw.
(lookup_minimal_symbol): Likewise for both.
* symtab.h (struct block): Add `hashtable' flag. Comment the
hashtable.
(BLOCK_HASHTABLE, BLOCK_BUCKETS, BLOCK_BUCKET): New macro.
(ALL_BLOCK_SYMBOLS): Update.
(BLOCK_SHOULD_SORT): Do not sort hashed blocks.
(struct symbol): Add `hash_next' pointer.
* symtab.c (lookup_block_symbol): Search using the hash table when
possible.
(find_pc_sect_symtab): Use ALL_BLOCK_SYMBOLS.
(search_symbols, find_addr_symbol): Likewise.
* dstread.c (process_dst_block): Clear hashtable bit for new block.
(read_dst_symtab): Likewise.
* jv-lang.c (get_java_class_symtab): Likewise.
* mdebugread.c: Include "gdb_assert.h".
(shrink_block): Assert that the block being modified is not hashed.
* coffread.c (patch_opaque_types): Use ALL_BLOCK_SYMBOLS.
* symmisc.c (free_symtab_block): Walk the hash table when freeing
symbols.
(dump_symtab): Recognize hashed blocks.
* printcmd.c (print_frame_args): Assert that function blocks do not
have hashed symbol tables.
* ada-lang.c (symtab_for_sym): Use ALL_BLOCK_SYMBOLS.
(fill_in_ada_prototype, debug_print_block): Likewise.
(ada_add_block_symbols): Use ALL_BLOCK_SYMBOLS. Handle hash tables.
* symtab.c (remove_params): New function.
(make_symbol_overload_list): Use it instead of cplus_demangle.
(overload_list_add_symbol): Likewise. Reorder. Fix memory leak.
New variables.
(i386nbsd_init_abi): Use these to initialize tdep->sigtramp_start
and tdep->sigtramp_end.
* i386obsd-nat.c: New file.
* config/i386/obsd.mh (NATDEPFILES): Add i386obsd-nat.o.
* i386-nat.c (child_post_startup_inferior): New function
calling i386_cleanup_dregs if
I386_USE_GENERIC_WATCHPOINTS is defined.
* config/i386/nm-i386.h: define CHILD_POST_STARTUP_INFERIOR
conditional to acknowledge that i386-nat.c has its
own child_post_startup_inferior function.
* i386-tdep.c (i386_do_pop_frame): Use I386_MAX_REGISTER_SIZE
instead of MAX_REGISTER_RAW_SIZE.
(i386_extract_return_value, i386_extract_struct_value_address):
Convert to use regcache.
(i386_gdbarch_init): Set max_register_raw_size and
max_register_virtual_size to I386_MAX_REGISTER_SIZE.
Set extract_return_value and extract_struct_value_address instead
of their deprecated variants.
