Yes. My patch is to make sure that empty CONSTRUCTOR is removed when it
can be removed, i.e. all its elements have been initialized.

I meant, removed in the C++ front-end.


We can add code to remove the empty CONSTRUCTOR in the C++ front-end. But it's only useful when all initializers are non-constrant and split out. When there are constant initializers, they will be left in the CONSTRUCTOR and result an non-empty CONSTRUCTOR. The gimplifier handles with such CONSTRUCTOR and removes it if it becomes empty. So we don't need to duplicate the code to remove the empty CONSTRUCTOR in the C++ front-end.
