I'm a little annoyed by the suggestion that this wouldn't be a real problem if I couldn't measure a performance difference. Depending on workload, other activity on the same machine, and phase of moon, this loop is between .1% and 1% of runtime, and my tweaks make it go about a third faster. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28364
