The command line options
-fdump-translation-unit
-fdump-class-hierarchy
don't seem to work.

However they are documented in both the Info and man pages.
Also, said documentation alludes to -fdump-tree, but -fdump-tree neither works nor seems to be documented.

 It seems Nathan missed that when removing said flag with:
 
   2001-06-05  Nathan Sidwell  <nathan@codesourcery.com>
 
         * c-common.h (flag_dump_translation_unit): Remove.
         (enum tree_dump_index): Define.
         (TDF_ADDRESS, TDF_SLIM): New #defines.
         (dump_node_to_file): Remove.
         (dump_node): Make extern. Add flags.
         (dump_flag, dump_enabled_p, dump_begin, dump_end,
         dump_switch_p): Prototype.
         * c-common.c (flag_dump_translation_unit): Remove.
         * c-decl.c (c_decode_option): Remove -fdump-translation-unit
         logic. Use dump_switch_p.
         * c-dump.h (struct dump_info): Add node and user fields.
         (dump_pointer): Declare.
         * c-dump.c (dump_node): Make extern. Add flags.
         (SOL_COLUMN, EOL_COLUMN, COLUMN_ALIGNMENT): New #defines.
         (dump_new_line, dump_maybe_newline): Use them.
         (dump_pointer): New function.
         (dequeue_and_dump): Check TDF_SLIM before dumping a _DECL's
         chain or function's body. Dump address, if TDF_ADDRESS set.
         (dump_flag): Define.
         (dump_node_to_file): Remove.
         (struct dump_file_info): New struct.
         (dump_files): New array.
         (dump_begin, dump_end, dump_enabled_p, dump_switch_p): Define.
         * c-lang.c (finish_file): Adjust dumping.
         * toplev.h (dump_base_name): Make extern.
         * invoke.texi: Document new flags.

 Installed, thanks.  (I added a full-stop at the end of the ChangeLog
 entry.)

 -fdump-translation-unit has been removed from gcc, so it should
 be removed from the documentation as well.
