| // ------------------- |
| // 10000000: length of first CIE = 0x10 |
| // 00000000: This is a CIE |
| // 03: version = 0x3 |
| // 7a 52 00: augmentation string "zR" -- pointer format is specified |
| // 01: code alignment factor 1 |
| // 7c: data alignment factor -4 |
| // 1e: return address register 30 (== x30). |
| // 01: 1 byte of augmentation |
| // 1b: pointer format 1b: DW_EH_PE_pcrel | DW_EH_PE_sdata4 |
| // 0c 1f 00: initial instructions: "DW_CFA_def_cfa x31 ofs 0" in this case |
| |
| // Next the FDE: |
| // ------------- |
| // 10000000: FDE length 0x10 |
| // 18000000: Uses CIE 0x18 backwards (only coincidentally same as above) |
| // 00000000: PC begin for this FDE is at 00000000 (relocation is applied here) |
| // 04000000: FDE applies up to PC begin+0x14 |
| // 00: Augmentation string length 0 for this FDE |
