| ; This generates 4 results for OpPtrNotEqual |
| |
| ; The workgroup variable is a struct containing a single float. |
| |
| ; Results: |
| ; 0: comparison of the workgroup var vs null |
| ; 1: comparison of the workgroup float vs null |
| ; 2: comparison of null struct vs null struct |
| ; 3: comparison of null float vs null float |
