How does it work when doing changes to anything in LDC (compiler, library), the change is generic and you want it to be merged. Will this be merged to the repos of GDC and DMD, or if you want to do a generic change, do you have to use the DMD repo?

Another question, do we need LDC to have own repos for the compiler and library. Would it possible to use the DMD submodules and then have the LDC extras in an specific LDC submodule?

One uses the most generic repo, i.e., upstream DMD, and has to wait for the change to trickle down to LDC and GDC (or, if it's super-important, open a PR with backported fix).

We don't just have some extra files but touch upstream files in all of these repos. We only use parts of the DMD repo; the frontend is a direct part of the ldc repo (dmd subdir), while DMD's test dir is the base for our dmd-testsuite repo/submodule.
