Ok i've hit an issue right now, since i changed to ` __builtin_elementwise_fma`
as per your suggestion now my code also falls under the
```
case Builtin::BI__builtin_elementwise_fma:
if (BuiltinElementwiseTernaryMath(TheCall))
return ExprError();
break;
```
in `SemaChecking.cpp` which is problematic because it rejects matrices... what
should i do?
`error: 1st argument must be a scalar or vector of floating-point types (was
'double2x2' (aka 'matrix<double, 2, 2>'))`
