Remove empty test suite `tests/run-make-fulldeps` After #109770, there were only a handful of tests left in the run-make-fulldeps suite. As of #126111, there are no longer *any* run-make-fulldeps tests, so now we can: - Remove the directory - Remove related bootstrap/compiletest code - Remove various other references in CI scripts and documentation. By removing this suite, we also no longer need to worry about discrepancies between it and ui-fulldeps, and we don't have to worry about porting tests from Makefile to [rmake](https://github.com/rust-lang/rust/issues/121876) (or whether rmake even works with fulldeps).
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>.
