--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:f678eab4f721ee3da1730e6c637b90a40aeb9d4d commit r17-3410-gf678eab4f721ee3da1730e6c637b90a40aeb9d4d Author: Richard Biener <[email protected]> Date: Wed Aug 19 11:38:57 2026 +0200 tree-optimization/126936 - schedule verification for live lanes The testcase shows both live lane extraction and (reduction) root schedule verification errorneously allow the use/root stmt to be the same as the placement point. But as we insert vector defs after the placement point we have to exclude it. PR tree-optimization/126936 * tree-vect-slp.cc (vect_bb_slp_mark_live_stmts): Exclude use_stmt from dominance check. (vect_schedule_slp): Likewise for root. * gcc.dg/vect/bb-slp-pr126936.c: New testcase.
