Move tests from `test/run-fail` to UI 2020-04-16 15:50:32 +09:00			`// run-fail`
Change the expected panic message for unsigned 2016-08-06 23:58:16 -04:00			`// error-pattern:thread 'main' panicked at 'attempt to multiply with overflow'`
Skip tests on emscripten 2020-05-08 00:39:02 +09:00			`// ignore-emscripten no processes`
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);`
