--- Comment #15 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
register const void __user *__p asm("r0") = __ptr;
etc. isn't a problem, here __p isn't const, only *__p is. The problem is if
the register variable itself is const.
So
arch/h8300/kernel/sim-console.c: register const unsigned _len
__asm__("er2") = n;
If n can be a constant or is const var initialized to constant etc.
The cases where a const register var doesn't have an initializer aren't a
problem either.
I don't see what should we warn about.
