--- Comment #7 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:55fe9aa0923699ee7232448f29462a08d94eae81 commit r16-9270-g55fe9aa0923699ee7232448f29462a08d94eae81 Author: Richard Biener <[email protected]> Date: Mon Jun 15 10:37:29 2026 +0200 tree-optimization/125786 - do not rewrite stmts in reassoc We may not simply rewrite def stmts of associative operands as they might have multiple uses. The following appropriately creates a new stmt instead. PR tree-optimization/125786 * tree-ssa-reassoc.cc (optimize_vec_cond_expr): Create a new stmt instead of rewriting an existing possibly multi-use one. * gcc.dg/torture/pr125786.c: New testcase. (cherry picked from commit b3763e32ea4b0bf9e68bb89eac9bf2d7ab92680c)
