Graphite is able to split the loop, but then the vectorizer punts anyway:
gcc -O3 -ftree-vectorizer-verbose=7 -fgraphite-identity -S t.c
t.c:11: note: not vectorized: number of iterations cannot be computed.
t.c:9: note: not vectorized: number of iterations cannot be computed.
t.c:3: note: vectorized 0 loops in function.
