The only difference between dmd, ldc and gdc (in effect) is

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/core/internal/atomic.d and now everything works.
