+; 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
+; 01: Version 1
+; 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)
