--- Comment #11 from DJ Delorie <dj at redhat dot com> 2011-01-22 00:37:35 UTC --- I set a breakpoint on the delete of that insn; at that time, the following insn did not have the /S set on it. At the time when the /S is added, the previous insn had already been deleted. So, it's delete first, set /s second, crash third. And it's not the setcc that's delted, it's the (compare) before it. The setcc is the one with the /s on it.
