Mostly-Unfair Criticisms of GCCMostly-Unfair Criticisms of GCCPosted Oct 25, 2007 9:28 UTC (Thu) by nix (subscriber, #2304)In reply to: Mostly-Unfair Criticisms of GCC by rmathew Parent article: A potential competitor for GCC: pcc
I thought that the Apple folks did some cachegrinding and found the problem to be largely GC-related poor memory locality and a correspondingly awful rate of cache misses? (IIRC this is being fixed by going back to obstacks in hot spots, but of course new optimizations are landing at a rate of knots which is slowing everything right back down again.)
