ffi::Error tvm::transform::EnrichPassErrorWithContext(const ffi::Error &err, const IRModule &mod, ffi::String pass_name, ffi::Optional<GlobalVar> func = ffi::Optional<GlobalVar>(std::nullopt))

Enrich a pass-time error with a TVMScript-rendered, underlined source location derived from the error’s embedded VisitErrorContext.

Returns an ffi::Error that preserves err’s kind, original message, and backtrace, and appends the failing pass name plus the offending location rendered as TVMScript (the whole mod, or local to func when provided). The returned error drops the VisitErrorContext payload, so an outer catch that re-enriches finds no context and returns the error unchanged.

Pure and total: never throws; returns err unchanged when there is no context, the path is unresolvable, or rendering fails.

Parameters:

• err – The error thrown by the pass body.

• mod – The IRModule the pass ran on (the access-path root, or the container of func when func is provided).

• pass_name – The name of the failing pass, shown in the message.

• func – When set, resolve and render the location local to mod->functions[func]; otherwise use the whole module.

Returns:

The enriched (or, on any fallback, the original) error.
