It's the same issue as the __muldi3 thing. cgraphbuild.c:rebuild_cgraph_edges is miscompiled at -O2 -fomit-frame-pointer by regalloc/reload because of some problem with elimination offsets. I think -fomit-frame-pointer is somewhat broken since the IRA merge. I'll attach testcases tomorrow. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37296
