 * `ignore-test` always ignores the test
 * `ignore-lldb` and `ignore-gdb` will skip the debuginfo tests
 * `min-{gdb,lldb}-version`
-* `should-fail` indicates that the test should fail; used for "meta testing",
-  where we test the compiletest program itself to check that it will generate
-  errors in appropriate scenarios. This header is ignored for pretty-printer tests.
-
-## Revisions
-
-Certain classes of tests support "revisions" (as of the time of this
-writing, this includes run-pass, compile-fail, run-fail, and
-incremental, though incremental tests are somewhat
-different). Revisions allow a single test file to be used for multiple
-tests. This is done by adding a special header at the top of the file:
-
-```
-// revisions: foo bar baz
-```
-
-This will result in the test being compiled (and tested) three times,
-once with `--cfg foo`, once with `--cfg bar`, and once with `--cfg
-baz`. You can therefore use `#[cfg(foo)]` etc within the test to tweak
-each of these results.
-
-You can also customize headers and expected error messages to a particular
-revision. To do this, add `[foo]` (or `bar`, `baz`, etc) after the `//`
-comment, like so:
-
-```
-// A flag to pass in only for cfg `foo`:
-//[foo]compile-flags: -Z verbose
-
-#[cfg(foo)]
-fn test_foo() {
-    let x: usize = 32_u32; //[foo]~ ERROR mismatched types
-}
-```
-
-Note that not all headers have meaning when customized too a revision.
-For example, the `ignore-test` header (and all "ignore" headers)
-currently only apply to the test as a whole, not to particular
-revisions. The only headers that are intended to really work when
-customized to a revision are error patterns and compiler flags.
