Summary: AIX uses the existing EH infrastructure in clang and llvm. The major differences would be 1. AIX do not have CFI instructions. 2. AIX uses a new personality routine, named __xlcxx_personality_v1. It doesn't use the GCC personality rountine, because the interoperability is not there yet on AIX. 3. AIX do not use eh_frame sections. Instead, it would use a eh_info section (compat unwind section) to store the information about personality routine and LSDA data address.
