Move tests from `test/run-fail` to UI 2020-04-16 15:50:32 +09:00			`//@ run-fail`
Print thread ID in panic message if thread name is unknown `panic!` does not print any identifying information for threads that are unnamed. However, in many cases, the thread ID can be determined. This changes the panic message from something like this: thread '<unnamed>' panicked at src/main.rs:3:5: explicit panic To something like this: thread '<unnamed>' (0xff9bf) panicked at src/main.rs:3:5: explicit panic Stack overflow messages are updated as well. This change applies to both named and unnamed threads. The ID printed is the OS integer thread ID rather than the Rust thread ID, which should also be what debuggers print. 2023-09-11 00:59:31 -04:00			`//@ regex-error-pattern: thread 'main'.*panicked`

tests: use `needs-subprocess` instead of `ignore-{wasm32,emscripten,sgx}` 2025-01-23 16:36:54 +08:00			`//@ needs-subprocess`
Add test for overflowing pow This would catch regressions of issue #28012. 2015-09-13 22:19:36 -04:00			`//@ compile-flags: -C debug-assertions`
