// This higher-order macro defines the error codes that are in use. It is used
// in the `rustc_errors` crate. Removed error codes are listed in the comment
// below.
//
// /!\ IMPORTANT /!\
//
// Error code explanation are defined in `error_codes/EXXXX.md` files. They must follow the RFC
// 1567 available here:
// https://rust-lang.github.io/rfcs/1567-long-error-codes-explanation-normalization.html
//
// Also, the contents of this macro is checked by tidy (in `check_error_codes_docs`). If you change
// the macro syntax you will need to change tidy as well.
//
// Both columns are necessary because it's not possible in Rust to create a new identifier such as
// `E0123` from an integer literal such as `0123`, unfortunately.
