Close https://github.com/llvm/llvm-project/issues/84002 Per [module.import]p7: > Additionally, when a module-import-declaration in a module unit of > some module M imports another module unit U of M, it also imports all > translation units imported by non-exported module-import-declarations > in the module unit purview of U. However, we only tried to implement it during the implicit import of primary module interface for module implementation unit. Also we didn't implement the last sentence from [module.import]p7 completely: > These rules can in turn lead to the importation of yet more > translation units. This patch tries to care the both issues.
