+ * symtab.h (lookup_block_symbol): Add mangled_name argument
+ to prototype.
+
+ * symmisc.c (maintenance_check_symtabs): Call lookup_block_symbol
+ with new mangled_name argument.
+ * linespec.c (decode_line_1): Likewise.
+ * valops (value_of_this): Likewise.
+ * symtab.c (lookup_transparent_type): Likewise.
+ (lookup_symbol_aux): Likewise. Accept new mangled_name argument.
+ (lookup_symbol): If we are given a mangled name, pass it down
+ to lookup_symbol_aux.
+ (lookup_block_symbol): If we are given a mangled name to check
+ against, only return symbols which match it.
+
2002-03-22 Christopher Faylor <cgf@redhat.com>
* win32-nat.c (child_create_inferior): Check for proper shell to use
