--- Comment #13 from Richard Biener <rguenth at gcc dot gnu.org> --- 433.milc 9180 336 27.4 * 9180 349 26.3 S 433.milc 9180 335 27.4 S 9180 340 27.0 * 433.milc 9180 344 26.7 S 9180 334 27.5 S 450.soplex 8340 225 37.1 * 8340 223 37.5 S 450.soplex 8340 226 36.9 S 8340 228 36.5 S 450.soplex 8340 223 37.4 S 8340 223 37.3 * 482.sphinx3 19490 386 50.5 * 19490 392 49.8 S 482.sphinx3 19490 384 50.7 S 19490 374 52.1 * 482.sphinx3 19490 394 49.5 S 19490 368 53.0 S comparing the fastest runtimes makes this a progression for both 433.milc and 482.sphinx3 and no difference for 450.soplex. I'll post the patch. For GCC 10 we'd want to play with applying the cost model to the whole loop nest instead.
