Take a look at: http://www.suse.de/~gcctest/SPEC/CFP/sb-haydn-head-64-32o-32bit/172_mgrid_recent_big.png And: http://www.suse.de/~gcctest/SPEC/CFP/sb-haydn-head-64-32o-32bit/301_apsi_recent_big.png You will see two big jumps, those are from the impact of adding the DCE. Likewise for ia64: http://www.suse.de/~gcctest/SPEC/CFP/sb-terbium-head-64/172_mgrid_recent_big.png http://www.suse.de/~gcctest/SPEC/CFP/sb-terbium-head-64/301_apsi_recent_big.png And amd64: http://www.suse.de/~gcctest/SPEC/CFP/sb-vangelis-head-64/172_mgrid_recent_big.png http://www.suse.de/~gcctest/SPEC/CFP/sb-vangelis-head-64/301_apsi_recent_big.png Thanks, Andrew Pinski -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32183
