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 key test here is that the personality routine is sanely encoded (under the

|
|
; 4GB, but you might need both +4GB and -4GB depending on where things end

|
; 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)
