Hi, runs finished for cheap vectorization model. I am running very cheap too. https://lnt.opensuse.org/db_default/v4/SPEC/latest_runs_report?younger_in_days=14&older_in_days=0&all_changes=on&min_percentage_change=0.02&revisions=e54acea9e5a821448af97c66e94a1e4c4f977d5d%2Ce87209a1269622017bf3d98bf71502dcb0f893aa%2C73474527aaa24d9236aca074c5494a07f40ce058&include_user_branches=on compares default -O2 (base), loop vectorize, slp vectorize. Put "O2" to machine name.

Code size growth is too large for -O2 for loop vectorize. SLP vectorize seems slight size win overall. Noteworthy regressions caused by slp are: 5-6%: xz (kaby, lto), milc (zenith), astar (zenith) 4-5%: xalancbmk (kaby), blender (kaby) 3-4%: xz (kaby, nolto), dealII (zenith) 2-3%: povray (kaby), astar (kaby), perlbench (kaby), sjeng (zenith), xz(zenith) We get 10% improvement on imagemagick (kaby), 17.5% (zenith), imagematick 6.99% (zenith) https://lnt.opensuse.org/db_default/v4/CPP/latest_runs_report?younger_in_days=14&older_in_days=0&all_changes=on&min_percentage_change=0.02&revisions=e54acea9e5a821448af97c66e94a1e4c4f977d5d%2Ce87209a1269622017bf3d98bf71502dcb0f893aa%2C73474527aaa24d9236aca074c5494a07f40ce058&include_user_branches=on Is for C++/polyhedron benchmarks. It shows several interesting regressions in polyhedron and tsvc for loop vectorization (over 100%) and also some for slp. Shall I try to search for bugzilla for these? Honza
