Hmm, in sourcebuild.texi I found:
...
@item vect_no_int_max
Target does not support a vector max instruction on @code{int}.
...

That looks related. [ I also found a patch introducing vect_no_uint_max 
here: https://gcc.gnu.org/ml/gcc-patches/2010-01/msg00152.html. ]

I'm not sure where to take it from here. Should I introduce 
vect_no_int_min, and use that in combination with vect_no_int_max?

Thanks,
