--- Comment #11 from rdapp at linux dot vnet.ibm.com ---
Any progress on this? The patch fixes the problem for s390x (no performance
regressions), but without it we see the regression in SPEC2006's libquantum all
the time, I guess the same is true for PowerPC? Any chance for it to go into
7.0?

For s390x, disabling the path-splitting pass does not introduce performance
regressions either and fixes libquantum but that would only be a very last
resort.
