In my test with Os,  I can see -0.6% in spec2000/gcc, but I couldn't see any change in the hot function (propagate_block), which takes just 11% in profile though.  As far as I check in my environment, 0.6% seems reasonable performance swing. I'm not sure if your regression on 176.gcc could be explained as swing or not. Please let me know you see any negative impact from this.
