We're looking for a way to speed up compilation of

Is there a dmd flag that shows the code after template
instantiations has been performed? Or some other dmd flag that
can help out finding hot-spots in the compiler in our case.
I have patches which add some tracing functionality.
Another approach is to throw the -v flag and just count which
semantic steps seem to take a long time.
