future status of generic vectors?

As I understand, they *will* be supported, but not through __attribute__
((mode (Vblah))), which will be only for non-generic vectors.  Vector modes
will die unless necessary in the machine descriptors, there will be vector
types that are lowered (e.g. to SImode or more likely BLKmode) before
tree->RTL expansion.
