| ; Regression test for an issue in which DAG combines created a constant i8x16 |
| ; vector with lane values of 255, which was outside the -128 to 127 range |
| ; expected by our ISel patterns (and similar for the i16 version) and caused an |
| ; ISel failure. The fix was to adjust out-of-range values manually in |
| ; BUILD_VECTOR lowering. |
