The symbol isn't emitted because its instantiatingModule is std.bitmanip
- which is not a root module - and thus the function is ignored by
DtoDefineFunction.

I think the comment in there (functions.cpp:922) is wrong. The frontend
seems to try hard to make sure instantiatingModule is a non-root module
if possible. That should mean LDC is not emitting templates that have a
non-root module instantiating them somewhere.

The idea probably is that you shouldn't need to emit functions again if
they were already emitted into a library you import and link. (if that's
desired, the correct fix is probably to require -lcurl when linking
phobos...)

I wonder if you can break that behavior with a cycle of
imports-that-instantiate. But I couldn't make a failing test case.

Cheers,
