Status quo up to gcc 4.2 was that gcc did not use them in the kernel on i386. The root of the problem is that your feeling and what the kernel currently implements do not match, and some flamewars^Wdiscussions might be required for getting this sorted out in either gcc or the kernel... Even if this specific issue in the kernel would turn out as a misoptimization, the general problem would still remain waiting to pop up at some later time at a different place. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32044
