fitzgen closed issue #439:
For example, wasmtime could use the function index within the wasm file as function name. It could also expose the wasm stack as fake variables, and when possible, it could show the arguments.
It would also be possible (probably behind a flag) to create .wat files and generate appropriate
.debug_linecontents.These things would significantly ease debugging of wasm programs without debuginfo.
fitzgen commented on issue #439:
Wasmtime's recent guest debugging supports stepping through the WAT.
