[PATCH] D70063: clang/Modules: Error if ReadASTBlock does not find the main module

[Adrian Prantl via Phabricator via cfe-commits]

aprantl added a comment.

Do we want to bother with a testcase for this?



================
Comment at: clang/include/clang/Basic/DiagnosticSerializationKinds.td:78
+def err_module_file_missing_definition : Error<
+  "module file '%0' is missing the main module's definition">, DefaultFatal;
 
----------------
Should this be `AST file` like in the above error message?
