Fix #131977 parens mangled in shared mut static lint suggestion Resolves #131977 for static mut references after discussion with Esteban & Jieyou on [t-compiler/help](https://rust-lang.zulipchat.com/#narrow/channel/182449-t-compiler.2Fhelp/topic/linting.20with.20parens.20in.20the.20HIR). This doesn't do anything to change the underlying issue if there are other expressions that generate lint suggestions which need to be applied within parentheses.
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>.
