55 Relocation section '.rel.text' at offset 0x190 contains 4 entries:
62 Each relocation is represented by ``Offset`` (8 bytes) and ``Info`` (8 bytes).
63 For example, the first relocation corresponds to the first instruction
64 (Offset 0x0) and the corresponding ``Info`` indicates the relocation type
81 Similarly, the second relocation is at ``.text`` offset ``0x18``, instruction 3,
