If this information is importamt, it should be above the line.  On the
other hand, it is much too detailed, making it hard to figure out what is
being said.  It would be better to just say diff of the .o files before
and after the changes shows no difference.  Likewise git diff -w shows no
difference.  That way one can quickly see what tests you did, without
being distracted by the machine name, the directory name, etc.
