--- Comment #2 from alalaw01 at gcc dot gnu.org ---
Being stupid here, but why does the outer loop having multiple exits matter -
it's the inner loop that should be vectorized?
FOO was a macro used to selectively make the test i>max disappear (enabling
vectorization) - the two commandlines had -DFOO=0 (vectorizes) and -DFOO=1
(doesn't).
