| 2 | ; Currently the verifier when traversing the graph induced by the debug info |
| 3 | ; metadata can reach the GV both from a DICompileUnit and a DIGlobalVariable |
| 4 | ; expression, so we emit a diagnostic twice. This is, not ideal, but the |
| 5 | ; alternative is that of keeping a map of visited GVs, which has non trivial |
| 6 | ; memory usage consequences on large testcases, or when LTO is the mode of |
| 7 | ; operation. |
