Forgive me if I've asked this before, but how does one determine what file a library has been loaded from? In particular, whether that file is a source file, a byte compiled file or a native compiled file. I've tried looking at load-history, and it tells me cc-engine was loaded from "/home/acm/emacs/emacs.git/sub-master-5/lisp/progmodes/cc-engine.elc" .. I think that's a lie. I suspect I'm dealing with a native compiled cc-engine, here. In fact, the string ".eln" doesn't occur anywhere in load-history, and I _know_ some of the files are native compiled - my build was configured with-native-compilation. So, how do I find this out?
