--- 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:dd32b9d9d1d74650c0e67dce5c5eef539846638e commit r17-5469-gdd32b9d9d1d74650c0e67dce5c5eef539846638e 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.
