------- Comment #1 from zadeck at naturalbridge dot com 2007-06-18 12:33 -------
I believe that the failure is due to a an insn illegally sharing with a
reg_equal note. Insn 8 is modified in regmove. When this happens, the
reg_equal note in insn 22 magically changes. That reg_equal note was changed
last in cse.
