When I run the following test with -fno-ivopts option:
make -s -C gcc check-gcc RUNTESTFLAGS="tree-ssa.exp=loop-16.c

I would like to know if this failure is caused by a bug or if there is
something wrong with my environment, or even there are restrictions associated
with the option -fno-ivopts.
Thanks.
