Assuming you still have the object files, do you think you link the
compiler using a combination of LCMC-enabled and non-LCMC-enabled .o
files, and thereby narrow down which modules are negatively impacted?

I'm just guessing that most modules are not transformed by LCMC,
or are not executed enough to affect the timings.
