Move tests from `test/run-fail` to UI 2020-04-16 15:50:32 +09:00			`//@ run-fail`
Change default panic handler message format. 2023-06-20 19:16:18 +02:00			`//@ error-pattern:thread 'main' panicked`
			`//@ error-pattern:attempt to multiply with overflow`
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`

Fix overflow checking in unsigned pow() The pow() method for unsigned integers produced 0 instead of trapping overflow for certain inputs. Calls such as 2u32.pow(1024) produced 0 when they should trap an overflow. This also adds tests for the correctly handling overflow in unsigned pow(). For issue number #34913 2016-07-20 18:23:52 -04:00			`let _x = 2u32.pow(1024);`
