> Can you clarify the sequence of events that results in getting in to the state where there are no object files to match? Is that a state that it should be possible to get in to, or is it indicative of an earlier problem too?

It might be a problem that .o files aren't being generated, but ultimately if the script fails to produce a set of llvm files all that will happen is that the inliner won't run.    I can't see what exactly is causing this, but one possibility is that the Objects directory exists, but was created earlier and has been emptied and the .o files are being dumped into some other directory.  I'd need a list of environment variables during the failure to see if this was the case.  Another possibility is that the build system is for whatever reason deleting these files before it gets to the script phase, but this seems unlikely.
