History
Jubilee 6b0c8cfedc Rollup merge of #132357 - m-ou-se:explicit-abi, r=compiler-errors 
Improve missing_abi lint

This is for the migration lint for https://github.com/rust-lang/rfcs/pull/3722

It is not yet marked as an edition migration lint, because `Edition2027` doesn't exist yet.

The lint now includes a machine applicable suggestion:

```
warning: extern declarations without an explicit ABI are deprecated
 --> src/main.rs:3:1
  |
3 | extern fn a() {}
  | ^^^^^^ help: explicitly specify the C ABI: `extern "C"`
  |

UI Tests

This folder contains rustc's UI tests.

Test Directives (Headers)

Typically, a UI test will have some test directives / headers which are special comments that tell compiletest how to build and intepret a test.

As part of an on-going effort to rewrite compiletest (see https://github.com/rust-lang/compiler-team/issues/536), a major change proposal to change legacy compiletest-style headers // <directive> to ui_test-style headers //@ <directive> was accepted (see https://github.com/rust-lang/compiler-team/issues/512.

An example directive is ignore-test. In legacy compiletest style, the header would be written as

// ignore-test

but in ui_test style, the header would be written as

//@ ignore-test

compiletest is changed to accept only //@ directives for UI tests (currently), and will reject and report an error if it encounters any comments // <content> that may be parsed as an legacy compiletest-style test header. To fix this, you should migrate to the ui_test-style header //@ <content>.
