+@item jump_table_data
+A @code{jump_table_data} insn is a placeholder for the jump-table data
+of a @code{casesi} or @code{tablejump} insn.  They are placed after
+a @code{tablejump_p} insn.  A @code{jump_table_data} insn is not part o
+a basic blockm but it is associated with the basic block that ends with
+the @code{tablejump_p} insn.  The @code{PATTERN} of a @code{jump_table_data}
+is always either an @code{addr_vec} or an @code{addr_diff_vec}, and a
+@code{jump_table_data} insn is always preceded by a @code{code_label}.
+The @code{tablejump_p} insn refers to that @code{code_label} via its
+@code{JUMP_LABEL}.
