So far, yes.

I don't see anything that requires or prohibits changing that for the
initial implementation.  If later a GCC developer wants to change it to
not promote e.g. char, that could be a refinement.  I don't think any of
the type-generic builtins allows non-floats anyway, so it would have no
effect to have it or not at this point.

The internal "no vops" builtin isn't documented AFAICT, I was just
following that example.  We don't want to confuse users into thinking they
can use it IMHO.  What do you suggest?
