[LLVMdev] Exception handling question

[Garrison Venn]

Hi Duncan,

Yes, but the personality function will get called in order for it to return _URC_CONTINUE_UNWIND.
When I said "it", I meant the personality function in its search phase not the cleanup/handler phase.
I believe, if I understand correctly, Jame's personality function is not being called during the search
phase. If this is not case, and his personality function is called during the search phase, then as
you indicated earlier, this is easy to solve.
