I see differences in the modified_in_p (test, insn) test in
cond_exec_process_insns. For IA64, this tests returns false, for my target
(TriMedia) it returns true, which causes that must_be_last is set and
that causes that cond_exec_process_insns returns false.

You should probably step through modified_in_p to see why it isn't working for your target. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
