| ; The key test here is that the personality routine is sanely encoded (under the |
| ; small memory model it must be an 8-byte value for full generality: code+data < |
| ; 4GB, but you might need both +4GB and -4GB depending on where things end |
| ; up. However, for completeness: |
| |
| ; First CIE: |
| ; ---------- |
| ; 1c000000: Length = 0x1c |
| ; 00000000: This is a CIE |
| ; 03: Version 3 |
| ; 7a 50 4c 52 00: Augmentation string "zPLR" (personality routine, language-specific data, pointer format) |
| ; 01: Code alignment factor 1 |
| ; 78: Data alignment factor: -8 |
| ; 1e: Return address in x30 |
| ; 07: Augmentation data 0xb bytes (this is key!) |
| ; 00: Personality encoding is DW_EH_PE_absptr |
| ; 00 00 00 00 00 00 00 00: First part of aug (personality routine). Relocated, obviously |
| ; 00: Second part of aug (language-specific data): absolute pointer format used |
| ; 1b: pointer format: pc-relative signed 4-byte. Just like GNU. |
| ; 0c 1f 00: Initial instructions ("DW_CFA_def_cfa x31 ofs 0" in this case) |
