What I do see from different means is that the number of calls to pow() increases from 63,907,869 to 1,953,139,629. Since pow() is not exactly cheap, I think this could be sufficient to explain the 1.8s difference I see. Note that the code has plenty of x**2 and x**a where a is real. > Does -fno-ipa-cp fix the regression? No. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40106
