I guess you're not using the default flags cause you don't what the SIMD
unit to be used (i.e. you want "generic" vectorization)? If so, maybe it's
more appropriate as a gcc.dg/tree-ssa/gen-vect-*.c test?

Yes, I agree. Or the test wouldn't run on 64-bit targets that don't support vectorization (s390x maybe?).
