Research direction

Start by locating the FIRTOOL strip-all implementation and its custom debug-information stripping pass. Compare it with MLIR’s debuginfo stripping pass, then determine whether the parameterized form should be proposed upstream; done means strip-all uses the MLIR pass and the upstream possibility is documented or addressed.
