| // mangled name to llvm GlobalValue, we don't see the clang level decl for |
| // an alias target when constructing the alias. Given that and that alias cycles |
| // are not representable in LLVM, we only note the issues when the cycle is |
| // first formed. |

| // FIXME: This error is detected early in CodeGen. Once the first error is |
| // found, Diags.hasErrorOccurred() returs true and we stop the codegen of the |
| // file. The consequence is that we don't find any subsequent error. |
