…ves, r=oli-obk Migrate compiletest to use `ui_test`-style `//@` directives ## Preface There's an on-going effort to rewrite parts of or the entirety of compiletest (<rust-lang/compiler-team#536>). A step towards this involve migrating compiletest tests to use the [`ui_test`](https://github.com/oli-obk/ui_test) framework, which involves changing compiletest directives in `// <directive-name>` style to `ui_test` `//@ <directive-name>` style (rust-lang/compiler-team#512). This PR aims to implement the directive-style change from `//` to `//`@`` for the remaining non-"ui" test suite tests. ## Key Changes 1. All `tests/` tests now use `//`@`` directives. 2. Compiletest only accepts `//`@`` and issues an error if an old-style directive is detected. 3. `// ignore-tidy` and `// ignore-tidy-*` are considered tidy directives and are ignored by compiletest header parsing. ## Diff Generation The diff is generated by: - Collecting directives from `tests/` via hijacking compiletest to emit successfully parsed directive lines. - Using a migration tool (<https://github.com/jieyouxu/compiletest-ui_test-header-migration/tree/master>) to replace `//` directives in compiletest tests with `//`@`.` ### Reproduction Steps 0. Delete the temporary file `$RUSTC_REPO_PATH/build/<target_triple>/test/__directive_lines.txt`, if the collection script was previously ran. 1. Use the <https://github.com/jieyouxu/rust/tree/collect-test-directives> collect-test-directives script, which outputs a temporary file recording headers occuring in each compiletest test. - You need to checkout this branch: `git checkout collect-test-directives`. - This needs to be rebased on latest master to ensure up-to-date test directives can be collected. - You need to run `./x test` on each of the `test/*` subfolders once: ```bash ./x test tests/assembly/ --stage 1 --force-rerun ./x test tests/codegen/ --stage 1 --force-rerun ./x test tests/codegen-units/ --stage 1 --force-rerun ./x test tests/coverage/ --stage 1 --force-rerun ./x test tests/coverage-run-rustdoc/ --stage 1 --force-rerun ./x test tests/debuginfo/ --stage 1 --force-rerun ./x test tests/incremental/ --stage 1 --force-rerun ./x test tests/mir-opt/ --stage 1 --force-rerun ./x test tests/pretty/ --stage 1 --force-rerun ./x test tests/run-make/ --stage 1 --force-rerun ./x test tests/run-make-fulldeps/ --stage 1 --force-rerun ./x test tests/run-pass-valgrind/ --stage 1 --force-rerun ./x test tests/rustdoc/ --stage 1 --force-rerun TARGET=<target-triple> ./x test tests/rustdoc-gui/ --stage 1 --force-rerun ./x test tests/rustdoc-js/ --stage 1 --force-rerun ./x test tests/rustdoc-js-std/ --stage 1 --force-rerun ./x test tests/rustdoc-json/ --stage 1 --force-rerun ./x test tests/rustdoc-ui/ --stage 1 --force-rerun ./x test tests/ui/ --stage 1 --force-rerun ./x test tests/ui-fulldeps/ --stage 1 --force-rerun ``` 2. Checkout the `migrate-compiletest-directives` branch. 3. Run the migration tool <https://github.com/jieyouxu/compiletest-ui_test-header-migration>. 4. Check that the migration at least does not cause test failures if you change compiletest to accept `//`@`` directives only. This is also required if the test outputs somehow need to be blessed. - `RUSTC_TEST_FAIL_FAST=1 ./x test tests/<secondary-directory> --stage 1 --bless` 5. Confirm that there is no difference after running the migration tool when you are on the `migrate-compiletest-directives` branch. ## Follow Up Work - [ ] Adjust rustc-dev-guide docs for compiletest directives (this time for all the other suites and modes). <rust-lang/rustc-dev-guide#1895>.
