fitzgen opened Issue #2204:

pretty_error should be replaced with methods on CodegenError that mutate the error and provide the context that pretty_error otherwise adds, and the CodegenError's Display impl should print what pretty_error creates when it has the necessary context.

These context-adding methods would be similar to how the wast crate adds file contents and filename context to errors with these methods:

• https://docs.rs/wast/24.0.0/wast/struct.Error.html#method.set_text
• https://docs.rs/wast/24.0.0/wast/struct.Error.html#method.set_path

Then we can delete pretty_error, and avoid using string as an error type in more places (notably in cranelift-filetests and its pretty_anyhow_error workaround).

pretty_error takes a reference to isa and func. Doing this would require CodegenError to borrow from them.

The idea is to take copies of the data gathered from those things and store them into the error, rather than borrow those things.

pretty_error needs the entire function, as the error shows the full function source. From the target isa it needs the register_info and encoding_info.
