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