| 3 | ; This test was failing because the inliner would inline @list_DeleteElement |
| 4 | ; into @list_DeleteDuplicates and then into @inf_GetBackwardPartnerLits, |
| 5 | ; turning the indirect call into a direct one. This allowed instcombine to see |
| 6 | ; the bitcast and eliminate it, deleting the original call and introducing |
| 7 | ; another one. This crashed the inliner because the new call was not in the |
| 8 | ; callgraph. |
