| (see <a href="tracepoint-object.html#tracepoint-object">tracepoint object</a>). The <var>gdb_jump_pad_head</var>, 8-byte long, is the |

| The <var>gdb_jump_pad_head</var> is updated head of jumppad. Both of |
| <var>target_address</var> and <var>gdb_jump_pad_head</var> are 8-byte long. |
| The <var>fjump</var> contains a sequence of instructions jump to jumppad entry. |
| The <var>fjump_size</var>, 4-byte long, is the size of <var>fjump</var>. |
