Btw, I've seen this as well and the "only" change is swapped edges out of a conditional from the split/unsplit dance. I was hoping somebody more familiar with the change intruducing that testcase was going to investigate but in the end it's probably RTL expansion presenting slightly different RTL IL to ifcvt.
