------- Additional Comments From rakdver at gcc dot gnu dot org 2005-01-24 01:40 ------- The patch that causes ivopts to reset just the relevant parts of the scev cache (just regtesting) instead of clearing it completely helps a bit -- the compile time for N=100 gets about 2x better and memory consumption about 10x.
Still there remain some inefficiences within the scev analysis itself. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18595
