The DWARF standard requires a name to be emitted and that's why we do emit
there something, to follow the standard. There are talks about changing this,
but no changes have been made yet.
That said, ideally we wouldn't be emitting nameless base types or __unknown__
named base types in this case, I guess the problem is just that we try to
remove const/volatile in a fixed order and your testcase has it exactly in the
opposite order. With:
typedef int my_int;
typedef volatile my_int volatile_my_int;
typedef const volatile_my_int const_volatile_my_int;
my_int v_my_int = 0;
volatile_my_int v_volatile_my_int = 1;
const_volatile_my_int v_const_volatile_my_int = 4;
int
main ()
{
return 0;
}
the result is expected, always refering to the previous typedef DIE.
