Why is that C++ can't create normal DECL's like everyone else?
Case in point:
(gdb)
unit size
...
addressable used BLK file minimal.c line 194 size unit size
$11 = void
(gdb) y
So we've got a parm decl that if you ask it for the DECL_SIZE, says 0,
but has a TYPE_SIZE of 12 by

I am not sure of what the exact relations between DECL_SIZE and TYPE_SIZE
are, but probably some verification coul

3. Not call layout_decl on the template types until they are completed.
In the abstract, this is the best choice. Although we need to know that
types are complete (which means (in the current implementation) that
TYPE_SIZE != NULL_TREE), but the C++ front end should not

This is what relayout_decl does.

Certainly an option; not doing extra work is good.
4. Make sure that template types are incomplete. That is, with
TYPE_SIZE/TYPE_SIZE_UNIT unset.
I think this makes a lot of sense considering the language se
