a.d : import b; void main() { f(); }
b.d : int f() { import c; return i; }
c.d : int i = 42;

The command
$ dmd -deps=a.deps -o- a.d
creates:
a (a.d) : public : object
(C:\\Soft\\dmd2d\\windows\\bin\\..\\..\\import\\druntime\\object.di)
b (b.d) : public : object
(C:\\Soft\\dmd2d\\windows\\bin\\..\\..\\import\\druntime\\object.di)
a (a.d) : public : b (b.d)

Apparently it's because semantic isn't run on the dependencies. It's in
Import::semantic where the import is printed.

You can verify this with that -rb feature.

Right, semantic3 for imported functions is only run during the inline pass.

I am not sure this really needs to be fixed:

b.d either needs to be built at some point, then the dependency is printed and
can be gathered by tools or it does not get built, in this case it does not
matter either, because any use of the function would need to be inlined,
causing the dependency to be printed. If the function is not used at all, then
the dependency also does not matter.

jfanatiker, the compiler is supposed to print the dependencies between all
modules when given just the starting point. This is the purpose of the -deps
switch, it is not intended to be run once for every module in the program. The
same goes for the verbose output (-v).

I see. You are right of course, I viewed it from an incremental build tool
perspective, where it would not matter, but for rdmd this bug is of course a
problem.
