It look like that dub compile with ldc but use dmd runtime and 
module core.internal.atomic has version only for dmd and gdc. How 
to make ldc use ldc runtime?

While druntime and Phobos will be patched for other platform targets, 
over all its the same library.

The same goes for core.atomic. You should not need to know that it has 
been patched. If you can call it and it gives you the right results, you 
can assume it worked.

Oh and $ dub build --compiler=ldc2

problem is when I build with ldc then id doesn't work and with 
dmd it does:

try compile this with ldc:
https://run.dlang.io/is/gngLFu

error on webite run.dlang.io is same as I have.

LDC has all LLVM intrinsics so try

---
import ldc.intrinsics;
ldc.intrinsics.llvm_atomic_rmw_add(...);

It look like atomicFetchAdd a atomicFetchSub was added to ldc 8 
days ago and my distro has old version. I replace 
core.internal.atomic with this 
https://raw.githubusercontent.com/ldc-developers/druntime/ldc/src/co
e/internal/atomic.d and now everything works.

It's not even in the latest stable version. Should be available in next 
release.
Also, please note that I haven't had the time to check if anything else 
was missing. If you do spot something else that is missing, please let 
me know.
