I'm not sure when this happened, but I noticed on the weekend that there has been an explosion in the time spent during the alias analysis phase. using cplusplus-grammer.ii, it use to compile on my machine in about 55 seconds, and its now up to about 150 seconds.
A quick gprof indicated about 60% of compile time is being spent in bitmap_bit_p, called from compute_may_aliases. someone made it WAY slow :-) Andrew
