------- 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.

------- Comment #4 from zadeck at naturalbridge dot com 2007-06-29 19:34 -------
there is a rumor being circulated by bonzini that one of honza's unsharing
patches fixes this. However, this fails on the current truck.
One positive note is that if you add in honza's illegal sharing detector, it
triggers that rather than the verify error.

Paolo's rumor is correct, Indeed. I somehow lost track in patches that was or
wasn't approved or tested. I've comited the fix now.
