--- Comment #14 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-16 branch has been updated by Tamar Christina <[email protected]>: https://gcc.gnu.org/g:a3a7c2da0508ceec0bd73994f62f9a4cb1ab3649 commit r16-9245-ga3a7c2da0508ceec0bd73994f62f9a4cb1ab3649 Author: Tamar Christina <[email protected]> Date: Fri Jun 12 11:56:54 2026 +0100 vect: use .VARYING for early break IV [PR125597] Similar to the mask control variable, this replaces and adds the temporary SSA var for early break scalar IVs with an IFN_VARYING until the replacement is done when we start vectorization. This prevents similar issues as the mask control variable when the IV expressions are folded. gcc/ChangeLog: PR tree-optimization/125597 * tree-vect-loop-manip.cc (vect_do_peeling): Create IFN_VARYING for early break scalar IV. * tree-vect-loop.cc (vect_update_ivs_after_vectorizer_for_early_breaks): Replace the IFN_VARYING with actual value. (cherry picked from commit 46f07a7b7d4d5b391723a756e5fb7673800bac57)
