--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
And -m32 -msse2 -mno-mmx of course warns:

t.c: In function ‘foo2’:
t.c:8:3: warning: MMX vector argument without MMX enabled changes the ABI
[-Wpsabi]
   bar2(*p);
   ^~~~~~~~

so it seems to work as designed.  Still it might be unfortunate to the
occasional user of generic vectors with MMX size that MMX is used
when not using intrinsics...
