Fix unwrap error in overflowing int literal Fixes #136675 it's maybe `negative` only from [check_lit](https://github.com/chenyukang/rust/blob/526e3288feb68eac55013746e03fb54d6a0b9a1e/compiler/rustc_lint/src/types.rs#L546), in this scenario the fields in `TypeLimits` is none. r? ``@oli-obk``
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 interpret a test.
As part of an ongoing 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 a legacy compiletest-style
test header. To fix this, you should migrate to the ui_test-style header
//@ <content>.
