      ; 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
