30 // -------------------
31 // 10000000: length of first CIE = 0x10
32 // 00000000: This is a CIE
34 // 7a 52 00: augmentation string "zR" -- pointer format is specified
35 // 01: code alignment factor 1
36 // 7c: data alignment factor -4
37 // 1e: return address register 30 (== x30).
38 // 01: 1 byte of augmentation
39 // 1b: pointer format 1b: DW_EH_PE_pcrel | DW_EH_PE_sdata4
40 // 0c 1f 00: initial instructions: "DW_CFA_def_cfa x31 ofs 0" in this case
44 // 10000000: FDE length 0x10
45 // 18000000: Uses CIE 0x18 backwards (only coincidentally same as above)
46 // 00000000: PC begin for this FDE is at 00000000 (relocation is applied here)
47 // 04000000: FDE applies up to PC begin+0x14
48 // 00: Augmentation string length 0 for this FDE
