9 Relocation Record
12 LLVM BPF backend records each relocation with the following 16-byte
18 Elf64_Xword r_info; // Relocation type and symbol index.
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,
83 The second relocation resolves to global variable ``g2`` which has a symbol
