Hm, we could arrange dwarf2out.c:current_unit_personality to be set to that of the first DECL_FUNCTION_PERSONALITY we stream in and in expr.c:get_personality_function use that for the eh_personality_any case. Sort of ugly as current_unit_personality is not exported, but ... For multi-language LTO it's probably still prefered to use the C personality for eh_personality_any, so conditionalizing this on !CFI assembler would be needed. Richard.
