The commit r208166 will cause some regression on ARM EHABI. This fix has been committed in r208715, and an assertion failure test case has been committed in r208770. This commit further extends the unittest so that the actual value in the handlerdata will be checked. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208790 91177308-0d34-0410-b5e6-96231b3b80d8

; ARM EHABI test for the handlerdata.
|
|
|
|
; This test case checks whether the handlerdata for exception
|
|
; handling is generated properly.
|
|
;
|
|
; (1) The handlerdata must not be empty.
|
|
; (2) LPStartEncoding == DW_EH_PE_omit
|
|
; (3) TTypeEncoding == DW_EH_PE_absptr
|
|
; (4) CallSiteEncoding == DW_EH_PE_udata4
