[Bug rtl-optimization/108273] Inconsistent dfa state between debug and non-debug
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108273 --- 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 :-)
