According to ARM EHABI section 9.2, if the __aeabi_unwind_cpp_pr1() or __aeabi_unwind_cpp_pr2() is used, then the handler data must be emitted after the unwind opcodes. The handler data consists of several words, and should be terminated by zero. In case that the .handlerdata directive is not specified by the programmer, we should emit zero to terminate the handler data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185422 91177308-0d34-0410-b5e6-96231b3b80d8
