  "message": "openmp: Fix up OpenMP expansion of collapsed loops [PR120564]\n\nMost of gimple_build_cond_empty callers call just build2 to prepare\ncondition which is put into GIMPLE_COND, but this one spot has been\nusing incorrectly fold_build2.  Now the arguments of the *build2 were\nalready gimplified, but the folding of some conditions can turn say\nunsigned_var \u003e INT_MAX into (int) unsigned_var \u003c 0 etc. and thus\nturn the condition into something invalid in gimple, because we only\ntry to regimplify the operands if they refer to some decl which needs\nto be regimplified (has DECL_VALUE_EXPR on it).\n\nFixed by also using build2 instead of fold_build2.\n\n2025-11-25  Jakub Jelinek  \u003cjakub@redhat.com\u003e\n\n\tPR middle-end/120564\n\t* omp-expand.cc (extract_omp_for_update_vars): Use build2 instead of\n\tfold_build2 to build argument for gimple_build_cond_empty.\n\n\t* c-c++-common/gomp/pr120564.c: New test.\n\n(cherry picked from commit a117fd63e423fb60f5e5f07125a11c7183109bf2)\n",
