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