I don't think you can do profiling in a dxe because it isn't using the mcount routines from the libc the application uses. Even if you get it working, either the mcount data from the dxe isn't written out (no exit handler) or worse it is written out and overwrites the data from the application. I think it's best to just not try to profile dxes. If we wanted to actually support something like this, we'd have to turn libc.a into a shared library, so that we could "link" dxes to it at runtime. Since that causes its own problems, I don't think it's worth it just to profile dxes - you can link the dxe code directly into your app if you're profiling it.
