Last year CodeSourcery had a contract to speed up the C++ front end at -O0, and we found that small linear reductions in memory usage corresponded directly to small linear reductions in time usage, at about a 2:1 ratio (so 1% less memory -> 0.5% less time). That wouldn't be worth bothering with except that there are *lots* of places where such reductions are available. We eventually got something like a 40% overall speedup just from this. (Sorry, I haven't got exact numbers.) zw
