 ```

 `llvm-nm` is used by `scripts/check_unit_wasm.py`, which is called by `scripts/compile_wasm_unit` after linking each unit.
+`llvm-dwarfdump` is used at unit compile time to extract the compact, out-of-band
+source map before debug sections are stripped from the runtime artifact. The
+map is consulted only on a wasm trap.
