Only Linux is supported at the moment, and other platforms quickly fault. As a result these tests would fail on non-Linux hosts. It may be worth making the tests more generic again as more platforms are supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174170 91177308-0d34-0410-b5e6-96231b3b80d8

; The first CIE:
|
|
; -------------------
|
|
; 10000000: length of first CIE = 0x10
|
|
; 00000000: This is a CIE
|
|
; 01: version = 0x1
|
|
; 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:
|
|
; -------------
|
|
; 18000000: FDE length 0x18
|
|
; 18000000: Uses CIE 0x18 backwards (only coincidentally same as above)
|
|
; 00000000: PC begin for this FDE is at 00000000 (relocation is applied here)
|
|
; 24000000: FDE applies up to PC begin+0x24
|
|
; 00: Augmentation string length 0 for this FDE
|
|
; Rest: call frame instructions
