I actually made the same mistake when generating the diffs. I attach the
correct diff when --with-precision=extended is given to configure. Similar
contents though, as far as I can judge. Strangely, the code without volatile is
overall larger:

-rw-r--r-- 1 root root 1456592 Apr 18 14:43 shower_core.s
-rw-r--r-- 1 root root 1450362 Apr 18 14:20 shower_core_volatile.s
