Hi All,

I am playing with a small hack OS for fun and in 2066 there are 
these undefined refs (I have no druntime):

_d_arraybounds (new to 2066)
_d_assert (new to 2066)
_d_unittest (new to 2066)
_Dmodule_ref (also in 2065)
_d_dso_registry (also in 2065)

It is trivial to stub these out but it got me wondering...

Is there any way to compile D that has no dependencies?


Thanks,
uri

The first one is about someone able to use D on microcontrollers with a few
k ram.:

The second one is about someone trying to strip almost everything out and
see what works:

They both go through the process of striping down the runtime and showing
what works.

This one is very useful, I recommend to implement it. It's just 
easier to live with it, than try to get rid of it.

But it would need to halt the system of course, because throwing 
a RangeError might not work in his minimalistic environment.

Halting the system, or jumping to a error routine seems better 
than running in undefined state.
