caller-save.c inserts the restore insns after the can_throw_internal ()
CALL_INSN
and as the rest of reload excepts fixup_abnormal_edges to fix the mess up.
But, fixup_abnormal_edges only inserts the instructions

I think it's caller-save's bug.
The use of fixup_abnormal_edges in reload and reg-stack is to move output

the eh edge, because by

It can't be inserted just on abnormal critical edges:
gcc_assert (!((e-flags EDGE_ABNORMAL) EDGE_CRITICAL_P (e)));
So I guess we could insert it on the EH edges if !EDGE_CRITICAL_P and only
only avoid

Maybe. I think you'll find that most of the time these edges *are* critical.
I don't think it's worth bothering to make the distinction.
