This has a hole where if a currently-unused file is not listed, but it is changed in such a way that it now matters (e.g., it changes include order, adds/removes includes, etc.), we need to recompile consumers. > what happens if someone adds an overload, or other interesting name > resolution to the module? We would need to do (at least) one of: - track considered-but-discarded decls (e.g., if something SFINAE'd away now matters because of a new decl); - track "new" decls since the last compile (not sure how the state tracking works here though) and recompile if any show up > "col": 12, > "kind": "Function", > "line": 3, So we change the decl hash if a comment adds a line? That seems like low-hanging fruit to me. Can we enumerate decls and use an index instead? That depends on preprocessor state though, so may be hard to externally verify… https://github.com/llvm/llvm-project/pull/72956 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
