Do you think 3.3 should be fixed?
I don't really think 3.2 handled -fnon-call-exceptions correctly.
The problem was exposed by a 3.3 change to insn_live_p. A test
was added to check if an insn might trap when flag_non_call_exceptions
is true.
As far as the PA goes, this was needed for libjava. We still don't
have libffi, needed for libjava, integrated yet.
