------- Comment #7 from rguenth at gcc dot gnu dot org 2008-03-02 11:00 ------- Note the COND_EXRPs will be lowered to control-flow while the MAX_EXPRs will retain a single BB. Still, on i686 the exactly same inner loop IL is created.
And btw I don't see mgrid miscomparing on our tester that runs with -O3 vs. -O3 -funroll-loops -fpeel-loops -ffast-math. But indeed the other tester with -O2 -ffast-math vs. -O2 -ffast-math with FDO miscompares since Feb. 25 (not so with 32bit or on IA64 though). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35418
