--- Comment #16 from Jeffrey A. Law <law at redhat dot com> --- Yea, just not enough time to push through the regression I've seen. At this point addressing fix-r4000-10.c looks like getting the DF/REG_NOTES consistent within the regcprop pass. Once that's in place we just need to iterate on a subset of blocks within regcprop and all the right things just happen. My schedule starts to open up next week and I expect to wrap this part of the BZ up then. Note there is still the fpr-moves-5 regression in this BZ that I haven't looked at yet. So even once fix-r4000-10.c is resolved we can't close this BZ.
