+  const vsetvl_info &get_header_info () const
+  {
+    gcc_assert (!empty_p ());
+    return infos.is_empty () ? m_info : infos[0];
+  }

Change it into get_entry_info (be consistent with mode-switching naming which also uses LCM).

+  const vsetvl_info &get_footer_info () const
+  {
+    gcc_assert (!empty_p ());
+    return infos.is_empty () ? m_info : infos[infos.length () - 1];
+  }

Change it into get_exit_info (be consistent with mode-switching naming which also uses LCM).
