Hi, all!
Recently I did some profiling of GCC to find hotspots and areas of possible
performance improvement among them. glibc malloc(3) is one of (perhaps known)
hotspots. It seemed rather strange to me that pool allocators call malloc(3) and
free(3) rather often, and spend considerable time in ma

I've committed this update to my earlier breakout of default handling. After
complaining about something because of 'none', we should fall through to the

In patch "Don't allow unsafe reductions in graphite" ( submitted

In this patch we enable it again, for the case that it's safe, in other
words, for the case that the fixed
