--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Kewen Lin from comment #1) > Created attachment 53126 [details] > move_applying LGTM (maybe the suggested unroll factor should be only applied if the suggestion was from a matching with/without SLP analysis, or in fact vect_analyze_loop_1 should communicate that down - disabling SLP when the one suggesting unrolling did the re-analysis).
