I'm not sure what you mean by "fix" though. I don't think we can change any of the constraints above.
I don't see why they couldn't be relaxed. What's stopping us from defining some builtins independently of the frontends, and don't all languages except Fortran use the normal builtins.def anyway? Also - if you can have an internal function without a fndecl, why wouldn't it work to allow that for builtins as well? But this is probably moot since I can now see a little more clearly what you want to do.
The main goal is to allow functions to be vectorised simply by defining the associated optab.
Ok. So these internal functions would support arbitrary modes like V[1248][SDX]F etc., unlike the builtins? That wasn't entirely clear from the patches I looked at, it seemed like you were just duplicating every builtin as an internal function (something to which I would have objected).
