--- Comment #10 from Segher Boessenkool  ---
The problem seems to be in generic scheduling code, not in the Power backend. 
Can someone confirm this, or point out where the problem is, is show the
problem no longer exists?  Whatever way we can resolve this :-)

r13-5154, this behavior change is expected, the priorities of some insns change
due to that commit, it further affects the scheduling decision on which insn is
scheduled ahead.

reported issue right after r13-5107-g6224db0e4d6d3b, but I can not reproduce
