--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-16 branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:669e0f0b33030611339767283c12237f8b2a7231 commit r16-9914-g669e0f0b33030611339767283c12237f8b2a7231 Author: Richard Biener <[email protected]> Date: Wed Oct 21 17:16:53 2026 +0200 tree-optimization/128069 - BB SLP and abnormal edges As vector SSA flow cannot cross abnormal edges we should split the BB SLP region on BBs with incoming abnormal edges. That avoids the issue seen in the testcase. PR tree-optimization/128069 * tree-vect-slp.cc (vect_slp_function): Split region at blocks with incoming abnormal edges. * gcc.dg/vect/bb-slp-pr128069.c: New testcase. (cherry picked from commit dd32b9d9d1d74650c0e67dce5c5eef539846638e)
