Please use -fdump-rtl-all since fwprop is not a tree pass. :-) Also, please check if the bug appears disappears with -O2 -fno-forward-propagate -funroll-loops versus -O2 -funroll-loops in both 130042 and 130043. If the -fno-forward-propagate would make a difference, this would be a great way to narrow the bug. Paolo -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34067
