This is a great idea! I personally also wouldn't mind going further in debug builds and actually create and store sequential IDs with the objects and take the small memory hit for improved debuggability. The `PersistentId` field in SelectionDAG works that way and has helped make the output more readable IMO. - Matthias > On Aug 28, 2018, at 5:22 PM, George Karpenkov via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Patch available at https://reviews.llvm.org/D51393 <https://reviews.llvm.org/D...

In various debug dumps (eg., Clang's -ast-dump), various objects (eg., Stmts and Decls in that -ast-dump) are identified by pointers. It's very reliable in the sense that no two objects would ever have the same pointer at the same time, but it's unpleasant that pointers change across runs. Having deterministic identifiers instead of pointers would aid debugging: imagine a
