2002-07-11 Daniel Jacobowitz <drow@mvista.com>
Based on patch from Daniel Berlin <dberlin@dberlin.org>.
* buildsym.c: Include "demangle.h" for SYMBOL_INIT_DEMANGLED_NAME.
(finish_block) For non-function blocks, hash the symbol table. For
function blocks, mark the symbol table as unhashed.
* minsyms.c (msymbol_hash): Return hash value without taking modulus.
(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.
