We can't make `scan()` const, since we will pass the member variable `Service` as a non-const reference to construct `DependencyScanningTool`. And we can't (or we don't want) assume the `getRequiredModules()` will be executed after `globalScan()`. We require to run `getSourceForModuleName()` after `globalScan()` since we have to. https://github.com/llvm/llvm-project/pull/66462 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
