Those symbols that are part of the ia64 and the x86-64 ABIs:

_Unwind_RaiseException
_Unwind_Resume
_Unwind_DeleteException
_Unwind_GetGR
_Unwind_SetGR
_Unwind_GetIP
_Unwind_SetIP
_Unwind_GetRegionStart
_Unwind_GetLanguageSpecificData
_Unwind_ForcedUnwind

together with the data types Unwind_Exception and _Unwind_Context,
