Yeah, the linkage is already tested. Currently we're checking the linkage is `external` (default linkage). For example, if the linkage is `linkonce_odr`, the output will be something like: `// CHECK-DAG: @_ZTSW3foo5Fruit = linkonce_odr constant` https://github.com/llvm/llvm-project/pull/75912 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
