Thanks, but we also need flags that were passed to gcc when editors/vi.c was
compiled. Probably you have to enable verbose output from your compile scripts.

No, the problem is that vectorizer runtime tests require some special
treatment. You can look at gcc.dg/vect/vect-2.c, where check_vect is called to
check for SSE2 support (on x86 targets).
I think that kind of C glue fun
