From Tom Tromey <tromey@cygnus.com> and Keith Seitz <?>:
* minsyms.c: #include <ctype.h>, for msymbol_hash_iw.
(compact_minimal_symbols): Added `objfile' argument.
Put symbols in the objfile's hash table.
(install_minimal_symbols): Put symbols in the objfile's demangled
hash table.
(lookup_minimal_symbol): Use hash table to find symbol in
objfile.
(msymbol_hash_iw, msymbol_hash, add_minsym_to_hash_table): New
functions.
(prim_record_minimal_symbol_and_info): Initialize the
hash link fields of the new minimal symbol.
* symtab.h (struct minimal_symbol): New fields `hash_next',
`demangled_hash_next'.
(msymbol_hash_iw, msymbol_hash, add_minsym_to_hash_table): Declare.
* objfiles.h (MINIMAL_SYMBOL_HASH_SIZE): New define.
(struct objfile): New fields `msymbol_hash',
`msymbol_demangled_hash'.
